详解手把手Maven搭建SpringMVC+Spring+MyBatis框架(超级详细版)

SSM（Spring+SpringMVC+Mybatis），目前较为主流的企业级架构方案。标准的MVC设计模式，将整个系统划分为显示层、Controller层、Service层、Dao层四层，使用SpringMVC负责请求的转发和视图管理，Spring实现业务对象管理, MyBatis作为数据对象持久化引擎。

一. 框架详情

Spring是一个轻量级的Java开发框架，它是为了解决企业应用开发的复杂性而创建的。Spring的用途不仅限于服务器端的开发。从简单性、可测试性和松耦合的角度而言，任何Java应用都可以从Spring中受益。 简单来说，Spring是一个轻量级的控制反转（IoC）和面向切面（AOP）的容器框架

SpringMVC属于SpringFrameWork的后续产品，分离了控制器、模型对象、分派器以及处理程序对象的角色，这种分离让它们更容易进行定制

MyBatis是一个基于Java的持久层框架。MyBatis提供的持久层框架包括SQL Maps和Data Access Objects（DAO）它消除了几乎所有的JDBC代码和参数的手工设置以及结果集的检索。MyBatis 使用简单的 XML或注解用于配置和原始映射，将接口和 Java映射成数据库中的记录

二. 创建Maven项目

1、Eclipse中用Maven创建项目

2、按默认Next

3、找到maven-archetype-webapp后，点击next

4、填写相应的信息，GroupID是项目组织唯一的标识符，实际对应JAVA的包的结构。ArtifactID就是项目的唯一的标识符，实际对应项目的名称，就是项目根目录的名称。Package填了默认给你建一个包，不写也可以。

5、刚建好的目录如下

6、Maven规定必须添加以下Source Folder：

src/main/resources
src/main/java
src/test/resources
src/test/java

在这步之前最好先项目上右键选择properties，然后点击java build path，在Librarys下，编辑JRE System Library，选择workspace default jre。

7、分别修改输出路径为，对应关系如下：

8、将项目转换成Dynamic Web Project，在项目上右键Properties，在左侧选择 Project Facets。

9、设置部署时的文件发布路径，删除test的两项，因为test是测试使用，并不需要部署。

设置将Maven的jar包发布到lib下。Add -> Java Build Path Entries -> Maven Dependencies -> Finish

三. Maven引入需要的JAR包

<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 http://maven.apache.org/maven-v4_0_0.xsd">   <modelVersion>4.0.0</modelVersion>   <groupId>com.yingjun.test</groupId>   <artifactId>TradingState</artifactId>   <packaging>war</packaging>   <version>2.0.1</version>    <properties>     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>     <maven.build.timestamp.format>yyyyMMddHHmmss</maven.build.timestamp.format>     <spring.version>3.2.9.RELEASE</spring.version>     <mybatis.version>3.1.1</mybatis.version>     <mybatisspring.version>1.1.1</mybatisspring.version>   </properties>    <dependencies>     <dependency>       <groupId>org.springframework</groupId>       <artifactId>spring-core</artifactId>       <version>${spring.version}</version>     </dependency>     <dependency>       <groupId>org.springframework</groupId>       <artifactId>spring-webmvc</artifactId>       <version>${spring.version}</version>     </dependency>     <dependency>       <groupId>org.springframework</groupId>       <artifactId>spring-test</artifactId>       <version>${spring.version}</version>     </dependency>     <dependency>       <groupId>org.mybatis</groupId>       <artifactId>mybatis</artifactId>       <version>${mybatis.version}</version>     </dependency>     <dependency>       <groupId>org.mybatis</groupId>       <artifactId>mybatis-spring</artifactId>       <version>${mybatisspring.version}</version>     </dependency>     <dependency>       <groupId>mysql</groupId>       <artifactId>mysql-connector-java</artifactId>       <version>5.1.34</version>     </dependency>     <dependency>       <groupId>junit</groupId>       <artifactId>junit</artifactId>       <version>4.11</version>       <scope>test</scope>     </dependency>     <dependency>       <groupId>c3p0</groupId>       <artifactId>c3p0</artifactId>       <version>0.9.1.2</version>     </dependency>     <dependency>       <groupId>org.aspectj</groupId>       <artifactId>aspectjweaver</artifactId>       <version>1.8.1</version>     </dependency>     <dependency>       <groupId>javax.servlet</groupId>       <artifactId>jstl</artifactId>       <version>1.2</version>     </dependency>     <dependency>       <groupId>javax.servlet</groupId>       <artifactId>servlet-api</artifactId>       <version>3.0</version>       <scope>provided</scope>     </dependency>     <dependency>       <groupId>javax.servlet.jsp</groupId>       <artifactId>jsp-api</artifactId>       <version>2.2</version>       <scope>provided</scope>     </dependency>     <dependency>       <groupId>commons-fileupload</groupId>       <artifactId>commons-fileupload</artifactId>       <version>1.3.1</version>     </dependency>     <dependency>       <groupId>commons-lang</groupId>       <artifactId>commons-lang</artifactId>       <version>2.6</version>     </dependency>     <dependency>       <groupId>commons-codec</groupId>       <artifactId>commons-codec</artifactId>       <version>1.9</version>     </dependency>     <dependency>       <groupId>org.apache.httpcomponents</groupId>       <artifactId>httpclient</artifactId>       <version>4.5</version>     </dependency>     <dependency>       <groupId>org.slf4j</groupId>       <artifactId>slf4j-api</artifactId>       <version>1.7.10</version>     </dependency>     <dependency>       <groupId>org.slf4j</groupId>       <artifactId>slf4j-log4j12</artifactId>       <version>1.7.10</version>     </dependency>     <dependency>       <groupId>log4j</groupId>       <artifactId>log4j</artifactId>       <version>1.2.17</version>     </dependency>     <dependency>       <groupId>com.alibaba</groupId>       <artifactId>fastjson</artifactId>       <version>1.1.41</version>     </dependency>     <dependency>       <groupId>org.codehaus.jackson</groupId>       <artifactId>jackson-mapper-asl</artifactId>       <version>1.9.13</version>     </dependency>   </dependencies>    <build>     <plugins>       <plugin>         <artifactId>maven-compiler-plugin</artifactId>         <version>2.3.2</version>         <configuration>           <source>1.7</source>           <target>1.7</target>         </configuration>       </plugin>       <plugin>         <artifactId>maven-war-plugin</artifactId>         <version>2.2</version>         <configuration>           <version>3.0</version>           <failOnMissingWebXml>false</failOnMissingWebXml>         </configuration>       </plugin>     </plugins>     <finalName>${project.artifactId}_${project.version}_${maven.build.timestamp}</finalName>   </build> </project> 

四. 相关配置文件配置，整合SSM框架

web.xml

<?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/j2ee" xmlns:web="http://xmlns.jcp.org/xml/ns/javaee"   xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"   version="2.4">    <!-- 配置 Spring -->   <context-param>     <param-name>contextConfigLocation</param-name>     <param-value>classpath:spring.xml</param-value>   </context-param>   <listener>     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>   </listener>   <!-- 防止Spring内存溢出监听器 -->   <listener>     <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>   </listener>    <!-- 配置springmvc -->   <servlet>     <servlet-name>springMVC</servlet-name>     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>     <init-param>       <param-name>contextConfigLocation</param-name>       <param-value>classpath:spring-mvc.xml</param-value>     </init-param>     <load-on-startup>1</load-on-startup>   </servlet>   <servlet-mapping>     <servlet-name>springMVC</servlet-name>     <url-pattern>/</url-pattern>   </servlet-mapping>      <!-- 字符集过滤器 -->   <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>    </web-app> 

spring.xml

为了代替手工使用 SqlSessionDaoSupport 或 SqlSessionTemplate 编写数据访问对象 (DAO)的代码,MyBatis-Spring 提供了一个动态代理的实现:MapperFactoryBean。这个类 可以让你直接注入数据映射器接口到你的 service 层 bean 中。当使用映射器时,你仅仅如调 用你的 DAO 一样调用它们就可以了,但是你不需要编写任何 DAO 实现的代码,因为 MyBatis-Spring 将会为你创建代理。

五. 利用MyBatis Generator自动创建实体类、映射文件以及DAO接口

MyBatis属于一种半自动的ORM框架，所以主要的工作就是配置Mapping映射文件，但是由于手写映射文件很容易出错，所以可利用MyBatis生成器自动生成实体类、DAO接口和Mapping映射文件。这样可以省去很多的功夫，将生成的代码copy到项目工程中即可。

生成代码需要的文件和jar并建立如下目录结构：

在generatorl.xml中配置相关的数据库连接，已经数据库表：

<?xml version="1.0" encoding="UTF-8"?>  <!DOCTYPE generatorConfiguration   PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"   "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">   <generatorConfiguration>   <!-- 数据库驱动 -->   <classPathEntry location="mysql-connector-java-5.1.34.jar" />   <context id="DB2Tables" targetRuntime="MyBatis3">     <commentGenerator>       <property name="suppressDate" value="true" />       <!-- 是否去除自动生成的注释 true：是 ： false:否 -->       <property name="suppressAllComments" value="true" />     </commentGenerator>     <!--数据库链接URL，用户名、密码 -->     <jdbcConnection driverClass="com.mysql.jdbc.Driver"       connectionURL="jdbc:mysql://192.168.1.194:3306/noc"        userId="root" password="root">     </jdbcConnection>     <javaTypeResolver>       <property name="forceBigDecimals" value="false" />     </javaTypeResolver>     <!-- 生成模型的包名和位置 -->     <javaModelGenerator targetPackage="com.yingjun.test.model"       targetProject="src">       <property name="enableSubPackages" value="true" />       <property name="trimStrings" value="true" />     </javaModelGenerator>     <!-- 生成映射文件的包名和位置 -->     <sqlMapGenerator targetPackage="com.yingjun.test.mapping"       targetProject="src">       <property name="enableSubPackages" value="true" />     </sqlMapGenerator>     <!-- 生成DAO的包名和位置 -->     <javaClientGenerator type="XMLMAPPER" targetPackage="com.yingjun.test.dao"         targetProject="src">        <property name="enableSubPackages" value="true" />     </javaClientGenerator>     <!-- 要生成的表 tableName是数据库中的表名或视图名 domainObjectName是实体类名 -->     <table tableName="other_list" domainObjectName="OtherList"       enableCountByExample="fasle" enableUpdateByExample="false"       enableDeleteByExample="false" enableSelectByExample="false"       selectByExampleQueryId="false" >     </table>   </context> </generatorConfiguration>  

打开CMD窗口 进入该目录结构，输入命令行：

java -jar mybatis-generator-core-1.3.2.jar -configfile generator.xml -overwrite

运行完成后会生成相应的dao mapper 和model，是不是很爽。

六. 建立Service层以及conrorller层

package com.yingjun.test.service; public interface OtherServiceI {      public String getOterList();  } 

package com.yingjun.test.service; import java.util.ArrayList; import java.util.Arrays; import java.util.HashSet; import java.util.List; import java.util.Map; import java.util.Set;  import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service;  import com.alibaba.fastjson.JSON; import com.alibaba.fastjson.serializer.SerializerFeature; import com.yingjun.test.dao.OtherListMapper; import com.yingjun.test.model.OtherList; import com.yingjun.test.model.OtherListDomain; @Service public class OtherServiceImpl implements OtherServiceI {      @Autowired   private OtherListMapper otherListMapper;   @Override   public String getOterList() {     Set<String> set=new HashSet<String>();     List<OtherList> list=otherListMapper.selectAll();     List<OtherListDomain> jsonList=new ArrayList<OtherListDomain>();     for(OtherList other:list){       String title=other.getTitle();       if(set.contains(title)){         continue;       }else{         List<OtherList> t_list=new ArrayList<OtherList>();         for(OtherList data:list){           if(title.equals(data.getTitle())){             t_list.add(data);           }         }         OtherListDomain domain=new OtherListDomain();         domain.setTitle(title);         domain.setItems(t_list);         jsonList.add(domain);         set.add(other.getTitle());       }     }     return JSON.toJSONString(jsonList, SerializerFeature.WriteMapNullValue);   }  } 

package com.yingjun.test.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody;  import com.alibaba.fastjson.JSON; import com.yingjun.test.service.OtherServiceI; import com.yingjun.test.service.StockStatusServiceI; @Controller @RequestMapping(value = "/") public class TSSController {      @Autowired   private OtherServiceI otherService;      @RequestMapping(value="/getOtherList",produces="text/html;charset=UTF-8" )    @ResponseBody   private String getOtherList(){     String json=otherService.getOterList();     return json;   } } 

七. 建立测试类

import java.util.List; import org.apache.log4j.LogManager; 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; @RunWith(SpringJUnit4ClassRunner.class)  @ContextConfiguration(locations = {"classpath:spring.xml"}) public class TestMybatis {    @Autowired   private OtherServiceI service;    @Test   public void test() {       String list=service.getOterList();       logger.info(list);   }    } 

八. 通过浏览器进行验证

http://localhost:8080/TzyjStateService/getOtherList

至此，测试成功，SSM三大框架的整合就完成了，有什么其他需求可以在此基础继续添
