??? </filter>
??? <filter-mapping>
??? ??? <filter-name>struts2</filter-name>
??? ??? <url-pattern>/*</url-pattern>
??? </filter-mapping>
</web-app>
3、配置spring配置文件
application.xml
<?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"

?????????? 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-/>
???
??? <!-- 配置dbcp数据源 -->
??? <bean id="dataSource" 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 -->

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_*" 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>
