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: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>
