struts2.2.3+spring3.1.0+mybatis3.1.0框架整合集成简单demo

近期公司要开发新的项目，要用struts2+mybatis+spring框架，所以学习了下，来自己的博客发表下，希望能给大家带来帮助！
主要实现用户的增删改查操作

1、导入相应的jar包

2、配置web.xml主要是配置struts2和spring

web.xml文件内容如下：

<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xsi:schemaLocation="http://java.sun.com/xml/ns/javaee    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">   <welcome-file-list>     <welcome-file>index.jsp</welcome-file>   </welcome-file-list>    <!-- 加载spring的配置文件 -->   <listener>     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>   </listener>   <!-- 配置spring配置文件加载的位置 -->   <context-param>     <param-name>contextConfigLocation</param-name>     <param-value>classpath:beans.xml</param-value>   </context-param>     <!-- 配置struts2 -->   <filter>     <filter-name>struts2</filter-name>     <filter-class>       org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>   </filter>   <filter-mapping>     <filter-name>struts2</filter-name>     <url-pattern>/*</url-pattern>   </filter-mapping>   </web-app> 

3、配置spring配置文件，主要包括配置数据源、事务、mybaits等
beans.xml配置文件详细如下：

<?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"   xmlns:aop="http://www.springframework.org/schema/aop"   xmlns:tx="http://www.springframework.org/schema/tx"   xsi:schemaLocation="http://www.springframework.org/schema/beans       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd       http://www.springframework.org/schema/aop        http://www.springframework.org/schema/aop/spring-aop-3.0.xsd       http://www.springframework.org/schema/tx       http://www.springframework.org/schema/tx/spring-tx-3.0.xsd       http://www.springframework.org/schema/context       http://www.springframework.org/schema/context/spring-context-3.0.xsd">      <!-- 采用注释的方式配置bean -->   <context:annotation-config />   <!-- 配置要扫描的包 -->   <context:component-scan base-package="com.pdsu.edu"></context:component-scan>      <!--proxy-target-class="true"强制使用cglib代理  如果为false则spring会自动选择-->   <aop:aspectj-autoproxy proxy-target-class="true"/>      <!-- 数据库配置文件位置 -->   <context:property-placeholder location="classpath:jdbc.properties" />      <!-- 配置dbcp数据源 -->   <bean id="dataSource" destroy-method="close">     <property name="driverClassName" value="${jdbc.driverClassName}" />     <property name="url" value="${jdbc.url}" />     <property name="username" value="${jdbc.username}" />     <property name="password" value="${jdbc.password}" />     <!-- 队列中的最小等待数 -->     <property name="minIdle" value="${jdbc.minIdle}"></property>     <!-- 队列中的最大等待数 -->     <property name="maxIdle" value="${jdbc.maxIdle}"></property>     <!-- 最长等待时间，单位毫秒 -->     <property name="maxWait" value="${jdbc.maxWait}"></property>     <!-- 最大活跃数 -->     <property name="maxActive" value="${jdbc.maxActive}"></property>     <property name="initialSize" value="${jdbc.initialSize}"></property>   </bean>      <!-- 配置mybitasSqlSessionFactoryBean -->   <bean id="sqlSessionFactory">     <property name="dataSource" ref="dataSource" />     <property name="configLocation" value="classpath:mybatis.xml"></property>   </bean>      <!-- 配置SqlSessionTemplate -->   <bean id="sqlSessionTemplate">     <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory" />   </bean>      <!-- 事务配置 -->   <bean id="transactionManager">     <property name="dataSource" ref="dataSource" />   </bean>      <!-- 使用annotation注解方式配置事务 -->   <tx:annotation-driven transaction-manager="transactionManager"/>  </beans> 

4.JDBC配置文件详细

jdbc.driverClassName=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/operationLog jdbc.username=root jdbc.password= jdbc.maxActive = 2 jdbc.maxIdle =5 jdbc.minIdle=1 jdbc.initialSize =3 jdbc.maxWait =3000 

5、配置mybatis主配置文件：

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration>   <typeAliases>     <typeAlias alias="user" type="com.pdsu.edu.domain.User"/>   </typeAliases>   <mappers>     <mapper resource="com/pdsu/edu/domain/sqlMappers/user.xml" />   </mappers> </configuration> 

6、配置user.xml文件

<?xml version="1.0" encoding="utf-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.pdsu.edu.domain.User">      <resultMap type="com.pdsu.edu.domain.User" id="userResult">     <result property="id" column="id" jdbcType="INTEGER" javaType="java.lang.Integer" />     <result property="username" column="username" />     <result property="password" column="password" />   </resultMap>   <select id="userLogin" parameterType="user" resultMap="userResult">     select * from user      where        username=#{username} and password=#{password}   </select>    <select id="selectAllUser" resultMap="userResult">     select * from user   </select>    <select id="findUserById" parameterType="int" resultMap="userResult">     select *     from user where id=#{id}   </select>    <insert id="insertUser" parameterType="user">    <![CDATA[     insert into     user(username,password) values(#{username},#{password})     ]]>   </insert>    <update id="updateUser" parameterType="user">     update user set     username=#{username},password=#{password} where id=#{id}   </update>      <delete id="deleteUser" parameterType="int">     delete from user where     id=#{id}   </delete>  </mapper> 

7、User实体的写法

public class User implements Serializable {   private static final long serialVersionUID = -4415990281535582814L;   private Integer id;   private String username;   private String password;    public Integer getId() {     return id;   }    public void setId(Integer id) {     this.id = id;   }    public String getUsername() {     return username;   }    public void setUsername(String username) {     this.username = username;   }    public String getPassword() {     return password;   }    public void setPassword(String password) {     this.password = password;   }    @Override   public String toString() {     return "User [id=" + id + ", password=" + password + ", username=" + username + "]";   }    @Override   public int hashCode() {     final int prime = 31;     int result = 1;     result = prime * result + ((id == null) ? 0 : id.hashCode());     return result;   }    @Override   public boolean equals(Object obj) {     if (this == obj)       return true;     if (obj == null)       return false;     if (getClass() != obj.getClass())       return false;     User other = (User) obj;     if (id == null) {       if (other.id != null)         return false;     } else if (!id.equals(other.id))       return false;     return true;   } } 

8、UserDao的写法

public interface UserDao {    public abstract void insertUser(User user);    public abstract void updateUser(User user);    public abstract void deleteUser(Integer userId);    public abstract User findUserByid(Integer userId);    public abstract List<User> findAll();    public abstract User userLogin(User user);  } 

9、UserDao的实现

@Repository public class UserDaoImpl implements UserDao {   private final String INSERT_USER = "insertUser";   private final String UPDATE_USER = "updateUser";   private final String DELETE_USER = "deleteUser";   private final String FIND_USER_BYID = "findUserById";   private final String SELECT_ALL_USER = "selectAllUser";   private final String USER_LOGIN = "userLogin";   @Autowired   private SqlSessionTemplate sqlSessionTemplate;    public void insertUser(User user) {     sqlSessionTemplate.insert(INSERT_USER, user);   }    public void updateUser(User user) {     sqlSessionTemplate.update(UPDATE_USER, user);   }    public void deleteUser(Integer userId) {     sqlSessionTemplate.delete(DELETE_USER, userId);   }    public User findUserByid(Integer userId) {     return sqlSessionTemplate.selectOne(FIND_USER_BYID, userId);   }    public List<User> findAll() {     return sqlSessionTemplate.selectList(SELECT_ALL_USER);   }    public User userLogin(User user) {     return sqlSessionTemplate.selectOne(USER_LOGIN, user);   } } 

10、UserService接口

public interface UserService {    // 添加用户   public abstract void addUser(User user);    public abstract void updateUser(User user);    public abstract void deleteUser(Integer userId);    public abstract User findUserById(Integer userId);    public abstract List<User> findAllUser();    public abstract User login(User user);  } 

11、UserService接口的实现

@Service @Transactional public class UserServiceImpl implements UserService {    @Autowired   private UserDao userDao;    // 添加用户   public void addUser(User user) {     userDao.insertUser(user);   }    // 更新用户   public void updateUser(User user) {     userDao.updateUser(user);   }    public void deleteUser(Integer userId) {     userDao.deleteUser(userId);   }    public User findUserById(Integer userId) {     return userDao.findUserByid(userId);   }    public List<User> findAllUser() {     return userDao.findAll();   }    public User login(User user) {     return userDao.userLogin(user);   } } 

12、配置Struts2

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts>     <constant name="struts.i18n.encoding" value="UTF-8"/>       <!-- 指定默认编码集 ，作用于HttpServletRequest的setCharacterEncoding（）和freemarker，vilocity的输出 -->   <constant name="struts.configuration.xmlreload" value="true"/>       <!-- 当struts配置文件修改时是否自动加载 -->   <constant name="struts.devMode" value="true"/>       <!-- 开发模式下打印详细的错误信息 -->   <constant name="struts.ui.theme" value="xhtml"/>      <package name="user" namespace="/user" extends="struts-default">     <action name="user_*" method="{1}">       <result name="success" type="redirectAction">user_queryAllUser.action</result>       <result name="input">/index.jsp</result>       <result name="userList">/userList.jsp</result>       <result name="addUser">/userAdd.jsp</result>       <result name="updateUser">/userUpdate.jsp</result>     </action>   </package> </struts>   

13、UserAction具体实现

@Controller @Scope("prototype") public class UserAction extends ActionSupport {   @Autowired   private UserService userService;   private User user;   private List<User> userList;    public String execute() throws Exception {     return null;   }    public String login() {     if (user != null) {       User user2 = userService.login(user);       if (user2 != null) {         return SUCCESS;       }     }     this.addFieldError("user.username", "用户名或密码错误!");     return INPUT;   }    public String addUI() {     return "addUser";   }    public String updateUI() {     user = userService.findUserById(user.getId());     return "updateUser";   }    public String add() {     userService.addUser(user);     return SUCCESS;   }    public String delete() {     userService.deleteUser(user.getId());     return SUCCESS;   }    public String update() {     userService.updateUser(user);     return SUCCESS;   }    public User getUser() {     return user;   }    public void setUser(User user) {     this.user = user;   }    public String queryAllUser() {     userList = userService.findAllUser();     return "userList";   }    public List<User> getUserList() {     return userList;   }    public void setUserList(List<User> userList) {     this.userList = userList;   }  } 

14、登录页面的实现

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %>  <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html>  <head>   <base href="<%=basePath%>">      <title>用户登录</title>   <meta http-equiv="pragma" content="no-cache">   <meta http-equiv="cache-control" content="no-cache">   <meta http-equiv="expires" content="0">     <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">   <meta http-equiv="description" content="This is my page">   <!--   <link rel="stylesheet" type="text/css" href="styles.css">   -->   <s:head/>  </head>    <body>   <center>     <h1>用户登录</h1>     <s:a action="user_addUI" namespace="/user">添加新用户</s:a>     <s:form action="user_login" namespace="/user" method="post">       <s:textfield label="用户名" name="user.username"></s:textfield>       <s:password label="密码" name="user.password"></s:password>       <s:submit value="登录"></s:submit>     </s:form>   </center>  </body> </html> 

15、添加页面

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html>  <head>      <title>添加新用户</title>      <meta http-equiv="pragma" content="no-cache">   <meta http-equiv="cache-control" content="no-cache">   <meta http-equiv="expires" content="0">     </head>    <body>   <center>     <h1>添加新用户</h1>     <s:form action="user_add" namespace="/user" method="post">       <s:textfield label="用户名" name="user.username"></s:textfield>       <s:password label="密码" name="user.password"></s:password>       <s:submit value="提交"></s:submit>     </s:form>   </center>  </body> </html> 

16、修改页面

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html>  <head>      <title>修改用户</title>      <meta http-equiv="pragma" content="no-cache">   <meta http-equiv="cache-control" content="no-cache">   <meta http-equiv="expires" content="0">     </head>    <body>   <center>     <h1>修改用户</h1>     <s:form action="user_update" namespace="/user" method="post">       <s:hidden name="user.id"></s:hidden>       <s:textfield label="用户名" name="user.username"></s:textfield>       <s:password label="密码" name="user.password"></s:password>       <s:submit value="提交"></s:submit>     </s:form>   </center>  </body> </html> 

17、列表页面

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html>  <head>      <title>用户列表</title>      <meta http-equiv="pragma" content="no-cache">   <meta http-equiv="cache-control" content="no-cache">   <meta http-equiv="expires" content="0">     </head>    <body>   <center>     <h2>用户列表</h2>     <h3><s:a action="user_addUI" namespace="/user">添加新用户</s:a> </h3>     <table>       <tr>         <th>用户id</th>         <th>用户名称</th>         <th>用户密码</th>         <th>操作</th>       </tr>       <s:iterator value="userList">         <tr>           <td><s:property value="id"/> </td>           <td><s:property value="username"/> </td>           <td><s:property value="password"/> </td>           <td><s:a action="user_updateUI" namespace="/user"><s:param name="user.id">${id}</s:param>修改</s:a>            <s:a action="user_delete" namespace="/user"><s:param name="user.id">${id}</s:param>删除</s:a></td>         </tr>       </s:iterator>     </table>   </center>  </body> </html>
