struts2.2.3 + spring3.1.0 + mybatis3.1.0集成简单demo

项目下载地址：http://download.csdn.net/detail/afgasdg/4171359

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" class="org.apache.commons.dbcp.BasicDataSource" 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" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="configLocation" value="classpath:mybatis.xml"></property>
    </bean>  
 
    <!-- 配置SqlSessionTemplate -->
    <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
        <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory" />
    </bean>  
 
    <!-- 事务配置 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <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_*" class="userAction" 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">

  <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 width="90%" border="1">
            <tr>
