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">

             <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">

             <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">

         </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">
