前言
今天復習一下SpringMVC+Hibernate的搭建，本來想著將Spring-Security權限控制框架也映入其中的，但是發現內容太多了，Spring-Security的就留在下一篇吧，這篇主要搭建SpringMVC4.1.4和Hibernate4.3.8，之前也打了好多SpringMVC的，這部分已經非常的熟悉了，畢竟業開發過一年多SpringMVC的，這次持久層採用Hibernate，數據源採用c3p0，數據庫暫採用MySQL，主要是想複習一下Hibernate。搭建SpringMVC+Hibernate的框架的思路如下：
1、設計數據庫：設計好表結構，最好符合3NF，採用Hibernate tools將設計好的表自動生成對應的實體entity。
1、創建Maven項目，按需映入Maven包依賴。
2、搭建Spring：配置Spring對控件層Bean的注入。
3、搭建Hibernate：配置數據源，配置SessionFactory，配置事務，以及二級緩存ehcache的配置。
4、測試Spring+Hibernate的框架搭建，寫單元測試JUnit，測試事務配置等。
5、映入SpringMVC：配置SpringMVC配置信息。
6、配置web.xml容器
7、測試三個框架的整合：Maven編譯打包部署服務器，測試。
1、數據庫設計
設計一個權限、角色、用戶的表。自然如果一個用戶可以有多個角色，一個角色多個用戶所擁有；一個角色擁有多個權限，一個權限對應多個角色。所以按照數據庫表結構設計，符合3NF的話我們需要5張表進行存在。表的具體信息就不列出了（可以下在源碼，裡面還有數據庫），表關係如下：
這裡面ID才用到是java的UUID（36位）
2、創建Maven項目，編寫pom.xml文件
創建一個Maven的webapp項目，編寫pom.xml文件，引入所需的包依賴，我這裡就將所需的全部的映入了。
pom.xml文件內容如下:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

</configuration> </configuration> </plugin> </plugins> </build></project>3、引入Spring配置
編寫配置文件，配置文件放在src/main/resources資源目錄下（下同）。
項目所需的配置信息config.properties
#application configs#jdbc c3p0 configjdbc.driver = com.mysql.jdbc.Driverjdbc.url = jdbc:mysql://localhost:3306/work?useUnicode=true&characterEncoding=utf-8jdbc.username = rootjdbc.password = 12345#hibernate confighibernate.dialect = org.hibernate.dialect.MySQLDialecthibernate.show_sql = truehibernate.format_sql = falsehibernate.hbm2ddl.auto = updatehibernate.cache.use_second_level_cache = truehibernate.cache.use_query_cache = truehibernate.cache.region.factory_class = org.hibernate.cache.ehcache.EhCacheRegionFactoryhibernate.cache.provider_configuration_file_resource_path = ehcache.xml
3.1、spring配置
spring.xml的配置文件如下：
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd"> <!-- 加載配置文件--> <context:property-placeholder location="classpath:config.properties"/> <!-- 掃描service自動注入為bean --> <context:component-scan base-package="org.andy.work.service.impl,org.andy.work.dao.impl" /></beans>
上面spring配置了對應包下組件bean自動注入管理，我們需要將dao,service的實現類交由spring管理，如（@Repository，@Service）。
3.2、引入日誌文件配置Log4j
log4j.properties的配置文件如下：### set log levels ###log4j.rootLogger = INFO , C , D , E ### console ###log4j.appender.C = org.apache.log4j.ConsoleAppenderlog4j.appender.C.Target = System.outlog4j.appender.C.layout = org.apache.log4j.PatternLayoutlog4j.appender.C.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n### log file ###log4j.appender.D = org.apache.log4j.DailyRollingFileAppenderlog4j.appender.D.File = ../logs/springmvc_hibernate_demo.loglog4j.appender.D.Append = truelog4j.appender.D.Threshold = INFO log4j.appender.D.layout = org.apache.log4j.PatternLayoutlog4j.appender.D.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n### exception ###log4j.appender.E = org.apache.log4j.DailyRollingFileAppenderlog4j.appender.E.File = ../logs/springmvc_hibernate_demo_error.log log4j.appender.E.Append = truelog4j.appender.E.Threshold = ERROR log4j.appender.E.layout = org.apache.log4j.PatternLayoutlog4j.appender.E.layout.ConversionPattern = [sspringmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n 4、Hibernate配置
Hibernate的配置主要包括：配置數據源c3p0，配置SessionFactory，配置事務管理器，配置事務管理，其spring-hibernate.xml文件如下：
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd"> <!-- 配置數據源c3p0 --> <bean id="dataSource" destroy-method="close"> <property name="driverClass" value="${jdbc.driver}" /> <property name="jdbcUrl" value="${jdbc.url}" /> <property name="user" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <!-- 請求超時時間--> <property name="checkoutTimeout" value="30000" /> <!-- 每60秒檢查所有連接池中的空閒連接。默認值: 0，不檢查--> <property name="idleConnectionTestPeriod" value="30" /> <!-- 連接數據庫連接池最大空閒時間--> <property name="maxIdleTime" value="30" /> <!-- 連接池初始化連接數--> <property name="initialPoolSize" value="5" /> <property name="minPoolSize" value="5" /> <property name="maxPoolSize" value="20" /> <!--當連接池中的連接耗盡的時候c3p0一次同時獲取的連接數。默認值: 3 --> <property name="acquireIncrement" value="5" /> </bean> <!-- 配置hibernate的SessionFactory --> <bean id="sessionFactory"> <!-- 注入數據源相關信息看源碼--> <property name="dataSource" ref="dataSource" /> <!-- hibernate配置信息--> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">${hibernate.dialect}</prop> <prop key="hibernate.show_sql">${hibernate.show_sql}</prop> <prop key="hibernate.format_sql">${hibernate.format_sql}</prop> <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop> <!-- 開啟二級緩存ehcache --> <prop key="hibernate.cache.use_second_level_cache">${hibernate.cache.use_second_level_cache}</prop> <prop key="hibernate.cache.use_query_cache">${hibernate.cache.use_query_cache}</prop> <prop key="hibernate.cache.region.factory_class">${hibernate.cache.region.factory_class}</prop> <prop key="hibernate.cache.provider_configuration_file_resource_path">${hibernate.cache.provider_configuration_file_resource_path} </prop> </props> </property> <!-- 掃描hibernate註解配置的entity --> <property name="packagesToScan" value="org.andy.work.entity" /> </bean> <!-- 配置事務管理器--> <bean id="transactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <!-- 配置事務增強處理Bean，指定事務管理器--> <tx:advice id="transactionAdvice" transaction-manager="transactionManager"> <!-- 配置詳細事務處理語義--> <tx:attributes> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="get*" propagation="SUPPORTS" read-only="true" /> <tx:method name="find*" propagation="SUPPORTS" read-only="true" /> <tx:method name="select*" propagation="SUPPORTS" read-only="true" /> <tx:method name="load*" propagation="SUPPORTS" read-only="true" /> <!-- 其他採用默認事務方式--> <tx:method name="*" /> </tx:attributes> </tx:advice> <!-- Spring aop事務管理--> <aop:config> <!-- 配置切入點--> <aop:pointcut id="transactionPointcut" expression="execution(* org.andy.work.service..*Impl.*(..))" /> <!-- 指定在txAdvice切入點應用txAdvice事務增強處理--> <aop:advisor pointcut-ref="transactionPointcut" advice-ref="transactionAdvice" /> </aop:config></beans>上面配置了二級緩存，ehcache，相關的具體信息查看上一篇Hibernate二級緩存以及ehcache的搭建配置，下面是二級緩存的配置。
4.1、ehcache.xml的配置
<?xml version="1.0" encoding="UTF-8"?><ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../config/ehcache.xsd"> <diskStore path="D:/ehcache" /> <!-- DefaultCache setting. --> <defaultCache maxElementsInMemory="1000" eternal="false" timeToIdleSeconds="120" timeToLiveSeconds="120" maxElementsOnDisk="1000000" overflowToDisk="true" memoryStoreEvictionPolicy="LRU"> </defaultCache> <!-- Special objects setting. --> <cache name="org.andy.work.entity.AcctUser" maxElementsInMemory="2" memoryStoreEvictionPolicy="LRU" eternal="true" diskPersistent="false" overflowToDisk="false" maxElementsOnDisk="1000000" /> </ehcache>
上面Hibernate二級緩存ehcache存放磁盤是D:/ehcache
5、生成業務entity實體
設計好數據表後，Hibernate的實體有工具Hibernate tools自動生成，Eclipse需要安裝Hibernate tools插件（我在線安裝過幾次都不成功，推薦使用links離線安裝，附錄將介紹），所以不需要手工的書寫，下面就貼一個用戶信息的實體，AcctUser.java
package org.andy.work.entity;// Generated 2015-2-3 10:43:00 by Hibernate Tools 4.0.0import java.util.Date;import java.util.HashSet;import java.util.Set;import javax.persistence.Column;import javax.persistence.Entity;import javax.persistence.FetchType;import javax.persistence.Id;import javax.persistence.JoinColumn;import javax.persistence.JoinTable;import javax.persistence.ManyToMany;import javax.persistence.Table;import javax.persistence.Temporal;import javax.persistence.TemporalType;import org.hibernate.annotations.Cache;import org.hibernate.annotations.CacheConcurrencyStrategy;import com.fasterxml.jackson.annotation.JsonIgnoreProperties;/** * AcctUser generated by hbm2java */@Entity@Table(name = "acct_user", catalog = "work")@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)public class AcctUser implements java.io.Serializable { /** * */ private static final long serialVersionUID = 6980093847795726310L; private String id; private String nickName; private String telephone; private Date registerTime; private Set<AcctRole> acctRoles = new HashSet<AcctRole>(0); public AcctUser() { } public AcctUser(String id, String nickName) { this.id = id; this.nickName = nickName; } public AcctUser(String id, String nickName, String telephone, Date registerTime, Set<AcctRole> acctRoles) { this.id = id; this.nickName = nickName; this.telephone = telephone; this.registerTime = registerTime; this.acctRoles = acctRoles; } @Id @Column(name = "id", unique = true, nullable = false, length = 36) public String getId() { return this.id; } public void setId(String id) { this.id = id; } @Column(name = "nick_name", nullable = false) public String getNickName() { return this.nickName; } public void setNickName(String nickName) { this.nickName = nickName; } @Column(name = "telephone") public String getTelephone() { return this.telephone; } public void setTelephone(String telephone) { this.telephone = telephone; } @Temporal(TemporalType.TIMESTAMP) @Column(name = "register_time", length = 19) public Date getRegisterTime() { return this.registerTime; } public void setRegisterTime(Date registerTime) { this.registerTime = registerTime; } @JsonIgnoreProperties(value={"acctUsers", "acctAuthorities"}) @ManyToMany(fetch = FetchType.LAZY) @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) @JoinTable(name = "acct_user_role", catalog = "work", joinColumns = { @JoinColumn(name = "user_id", nullable = false, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "role_id", nullable = false, updatable = false) }) public Set<AcctRole> getAcctRoles() { return this.acctRoles; } public void setAcctRoles(Set<AcctRole> acctRoles) { this.acctRoles = acctRoles; }}上面有幾個需要注意的：
上面大多數都是Hibernate tools自動生成的，但是有幾個需要手動添加：
1、如果這個實體使用二級緩存的話，需要添加@cache註解；
2、如果該實體裡面還有集合元素（set， map，list），如果實體要採用二級緩存，那麼這些集合元素必須也添加@cache註解。
3、@JsonIgnoreProperties註解是為了防止SpringMVC在json返回時產生循環輸出使用，如果不配置的話就會出現json死循環（還有多對多，一對多的屬性時）。
4、@JsonIgnore這個是在轉換成json是忽略該屬性，而@JsonIgnoreProperties(value={"acctUsers", "acctAuthorities"})則是忽略acctRoles裡面的acctUsers和acctAuthorites屬性。
6、創建Dao層
6.1Dao接口
Dao層和Service層我們肯定採用的是面相接口編程的思想，所以，我們先定義一個通用的Dao接口，GenericDao.java
package org.andy.work.dao;import java.io.Serializable;import java.util.List;/** * 創建時間：2015-2-6 下午2:26:42 * * @author andy * @version 2.2 * * Dao通用接口*/interface GenericDao<T, PK extends Serializable> { T load(PK id); T get(PK id); List<T> findAll(); void persist(T entity); PK save(T entity); void saveOrUpdate(T entity); void delete(PK id); void flush();}在定義具體的UserDao.java接口
package org.andy.work.dao;import org.andy.work.entity.AcctUser;/** * 創建時間：2015-2-6 下午2:43:50 * * @author andy * @version 2.2 * * 用戶Dao接口*/public interface UserDao extends GenericDao<AcctUser, String> {}6.2、Dao層實現類
我們需要將Dao層的實現類註入為bean，所以需要添加@Repository註解，UserDaoImpl如下：
package org.andy.work.dao.impl;import java.util.List;import org.andy.work.dao.UserDao;import org.andy.work.entity.AcctUser;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Repository;/** * 創建時間：2015-2-6 下午2:45:14 * * @author andy * @version 2.2 */@Repository("userDao")public class UserDaoImpl implements UserDao { @Autowired private SessionFactory sessionFactory; private Session getCurrentSession() { return this.sessionFactory.getCurrentSession(); } @Override public AcctUser load(String id) { return (AcctUser) this.getCurrentSession().load(AcctUser.class, id); } @Override public AcctUser get(String id) { return (AcctUser) this.getCurrentSession().get(AcctUser.class, id); } @SuppressWarnings("unchecked") @Override public List<AcctUser> findAll() { List<AcctUser> acctUsers = this.getCurrentSession().createQuery("from AcctUser").setCacheable(true).list(); return acctUsers; } @Override public void persist(AcctUser entity) { this.getCurrentSession().persist(entity); } @Override public String save(AcctUser entity) { return (String) this.getCurrentSession().save(entity); } @Override public void saveOrUpdate(AcctUser entity) { this.getCurrentSession().saveOrUpdate(entity); } @Override public void delete(String id) { AcctUser entity = this.load(id); this.getCurrentSession().delete(entity); } @Override public void flush() { this.getCurrentSession().flush(); }}7、創建Service層
7.1、Service層接口
package org.andy.work.service;import java.util.List;import org.andy.work.entity.AcctUser;/** * 創建時間：2015-2-6 下午3:18:57 * * @author andy * @version 2.2 * userService接口*/public interface UserService { AcctUser load(String id); AcctUser get(String id); List<AcctUser> findAll(); void persist(AcctUser entity); String save(AcctUser entity); void saveOrUpdate(AcctUser entity); void delete(String id); void flush();}7.2、service層實現類
UserServiceImpl就需要注入上面定義的Dao層bean。
package org.andy.work.service.impl;import java.util.List;import org.andy.work.dao.UserDao;import org.andy.work.entity.AcctUser;import org.andy.work.service.UserService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;/** * 創建時間：2015-2-6 下午3:24:16 * * @author andy * @version 2.2 UserService 的實現*/@Service("userService")public class UserServiceImpl implements UserService { @Autowired private UserDao userDao; @Override public AcctUser load(String id) { return userDao.load(id); } @Override public AcctUser get(String id) { return userDao.get(id); } @Override public List<AcctUser> findAll() { return userDao.findAll(); } @Override public void persist(AcctUser entity) { userDao.persist(entity); } @Override public String save(AcctUser entity) { return userDao.save(entity); } @Override public void saveOrUpdate(AcctUser entity) { userDao.saveOrUpdate(entity); } @Override public void delete(String id) { userDao.delete(id); } @Override public void flush() { userDao.flush(); }}8、測試Spring和Hibernate的整合
我們可以在src/test/java編寫測試類，測試上面的配置，如果測試成功已經基本大功告成。
package org.andy.work.service;import java.util.Date;import java.util.List;import java.util.UUID;import org.andy.work.entity.AcctUser;import org.apache.log4j.Logger;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.alibaba.fastjson.JSON;/** * 創建時間：2015-2-6 下午3:31:07 * * @author andy * @version 2.2 */@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = { "classpath:spring.xml", "classpath:spring-hibernate.xml" })public class TestUserService { private static final Logger LOGGER = Logger .getLogger(TestUserService.class); @Autowired private UserService userService; @Test public void save() { AcctUser acctUser = new AcctUser(); acctUser.setId(UUID.randomUUID().toString()); acctUser.setNickName("andy"); acctUser.setRegisterTime(new Date()); acctUser.setTelephone("13022221111"); String id = userService.save(acctUser); LOGGER.info(JSON.toJSONString(id)); }}9、引入SpringMVC
添加spring-mvc.xml文件
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd"> <!-- 自動掃描@Controller注入為bean --> <context:component-scan base-package="org.andy.work.controller" /> <!-- 以下為SpringMVC配置--> <mvc:annotation-driven> <!-- 返回json數據，@response使用--> <mvc:message-converters register-defaults="true"> <bean> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> <value>application/json;charset=UTF-8</value> </list> </property> </bean> </mvc:message-converters> </mvc:annotation-driven> <!-- 對模型視圖名稱的解析，即在模型視圖名稱添加前後綴--> <bean> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="prefix" value="/WEB-INF/views" /> <property name="suffix" value=".jsp" /> </bean></beans>
上面配置了包掃描Controller，[email protected]��，和視圖層的配置。
10、配置web.xml容器
web容器是web項目的大腦，所以web容器，首先需要引入spring，讓spring管理各個框架，並將其註入為bean。然後配置控制層的filter信息。並且配置了springmvc攔截的url為以.hmls結尾的請求。
web.xml文件如下：
<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>springmvc_demo</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring.xml,classpath:spring-hibernate.xml</param-value> </context-param> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>utf-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- openSessionInView配置作用是延遲session關閉到view層--> <filter> <filter-name>openSessionInViewFilter</filter-name> <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class> <init-param> <param-name>singleSession</param-name> <param-value>true</param-value> </init-param> </filter> <!-- 監聽servletContext，啟動contextConfigLocation中的spring配置信息--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 防止spring內存溢出監聽器--> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <servlet> <description>spring mvc servlet</description> <servlet-name>rest</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <!-- 此處配置的是SpringMVC的配置文件--> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>rest</servlet-name> <url-pattern>*.htmls</url-pattern> </servlet-mapping> <filter-mapping> <filter-name>openSessionInViewFilter</filter-name> <url-pattern>*.htmls</url-pattern> </filter-mapping> <!-- 配置session超時時間，單位分鐘--> <session-config> <session-timeout>30</session-timeout> </session-config> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list></web-app>
11、創建控制層Controller
控制層UserController
package org.andy.work.controller;import java.util.List;import org.andy.work.entity.AcctUser;import org.andy.work.service.UserService;import org.apache.log4j.Logger;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.ui.ModelMap;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;/** * 創建時間：2015-2-7 上午11:49:00 * @author andy * @version 2.2 * 描述： 用戶Controller */@Controller@RequestMapping("/user")public class UserController { private static final Logger LOGGER = Logger.getLogger(UserController.class); @Autowired private UserService userService; @RequestMapping("/showInfo/{userId}") public String showUserInfo(ModelMap modelMap, @PathVariable String userId){ LOGGER.info("查詢用戶：" + userId); AcctUser userInfo = userService.load(userId); modelMap.addAttribute("userInfo", userInfo); return "/user/showInfo"; } @RequestMapping("/showInfos") public @ResponseBody List<AcctUser> showUserInfos(){ LOGGER.info("查詢用戶全部用戶"); List<AcctUser> userInfos = userService.findAll(); return userInfos; }}12、創建視圖層
在src/main/webapp/WEB-INF/views下創建user/showInfo.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%><%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%><% String path = request.getContextPath(); String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><base href="<%=basePath%>" /><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><script type="text/javascript" src="js/jquery-1.9.1.min.js"></script><title>userInfo</title></head><body> 用戶信息暱稱： ${userInfo.nickName} 用戶id：${userInfo.id} 用戶電話:${userInfo.telephone } 註冊時間： <fmt:formatDate value="${userInfo.registerTime }" pattern="yyyy-MM-dd HH:mm:ss" /> 角色：[ <c:forEach items="${ userInfo.acctRoles}" var="role"> ${role.name } 權限[ <c:forEach items="${ role.acctAuthorities}" var="authority"> ${authority.name } </c:forEach> ] </c:forEach> ] <br /> ajax顯示全部用戶信息： <div id="show_all_user"></div></body><script type="text/javascript"> $.ajax({ type : "get", url : "user/showInfos.htmls", dataType : "json", success : function(data) { $(data).each( function(i, user) { var p = "<p>暱稱:" + user.nickName + " 電話:" + user.telephone + " 註冊時間:" + user.registerTime + " id:" + user.id + "</p>"; $("#show_all_user").append(p); }); }, async : true });</script></html>13、部署服務器測試
使用Maven打包部署：clean compile package
部署到tomcat，測試主要測試上面的http://localhost:8080/springmvc_hibernate_demo/user/showInfo/6e5afb1d-50e1-45fe-b6fe-b9e399415387.htmls
和http://localhost:8080/springmvc_hibernate_demo/user/showInfos.htmls （json數據返回）
上面視圖層就包含了這兩條url請求的測試：
ok，到此Spring+SpringMVC+Hibernate搭建完畢。
