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" 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">

      <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">
