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