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">
