3.编写UserDao、LoginLogDao类

　　  3.1 UserDao

　　　　

 package com.zwy.dao;

 import java.sql.ResultSet;
 import java.sql.SQLException;

 import org.springframework.beans.factory.annotation.Autowired;
 import org.springframework.jdbc.core.JdbcTemplate;
 import org.springframework.jdbc.core.RowCallbackHandler;
 import org.springframework.stereotype.Repository;

 import com.zwy.domain.User;

 /**
  * 通过@Repository注解定义一个DAO
  * */
 @Repository
 public class UserDao {
     @Autowired//自动注入JdbcTemplate
     private JdbcTemplate jdbcTemplate;

     /**
      * 查询用户是否存在
      * */
     public int getMacthCount(String username,String password){
         String sql="SELECT COUNT(*) FROM user WHERE user_name=? and password=? ";
         return jdbcTemplate.queryForInt(sql, username,password);
     }
     /**
      * 根据username找到相应的user 记录（对象）
      * */
     public User findUserByUserName(final String username){
         String sql="SELECT id,user_name,credits FROM user WHERE user_name=?";
         final User user=new User();
         jdbcTemplate.query(sql, new Object[]{username}, new RowCallbackHandler() {
                     public void processRow(ResultSet reSet) throws SQLException {
                         user.setId(reSet.getInt("id"));
                         user.setUserName(reSet.getString("user_name"));
                         user.setCredits(reSet.getInt("credits"));
                     }
         });
         return user;
     }
     /**
      * 根据useid更新相应的user （对象）在数据库中的记录
      * 更新积分，登录IP，登录时间
      * */
     public void updateLoginInfo(User user){
         String sql="UPDATE user  SET      credits=?,last_ip=?,last_time=?"
             +"  WHERE id=?";
         jdbcTemplate.update(sql, user.getCredits(),user.getLastIp(),user.getLastTime(),user.getId());
     }
 }

　　3.2 LoginLogDao类

package com.zwy.dao;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Repository;

import com.zwy.domain.UserLog;

@Repository
public class LoginLogDao {
    @Autowired
    private JdbcTemplate jdbcTemplate;

    /**
     * 插入一条登录记录
     * */
    public void insertLoginLog(UserLog user){
        String sql="INSERT INTO user_log(user_id,ip,log_time)"
            +" VALUES (?,?,?)";
        jdbcTemplate.update(sql,user.getUserId(),user.getIp(),user.getLogTime());
    }
}

　　省略了domain 实体类的代码

4.业务层UserService的代码

　　通过业务层组织持久化层的DAO完成业务逻辑操作

package com.zwy.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.zwy.dao.LoginLogDao;
import com.zwy.dao.UserDao;
import com.zwy.domain.User;
import com.zwy.domain.UserLog;

@Service
public class UserService {
    @Autowired
    private UserDao userDao;
    @Autowired
    private LoginLogDao loginLogDao;
    /**
     * 登录业务
     * */
    public boolean userLogin(String username,String password){
        int count=userDao.getMacthCount(username, password);
        return count>0;
    }
    /**
     * 根据username找到User对象
     * */
    public User finUserByUserName(String username){
        User user=userDao.findUserByUserName(username);
        return user;
    }
    /**
     * 成功登录，更新user的积分并添加到user_log
     * */
    public void successLoginLog(User user){
        if(user!=null){
            user.setCredits(5+user.getCredits());
            UserLog userLog=new UserLog();
            userLog.setUserId(user.getId());
            userLog.setIp(user.getLastIp());
            userLog.setLogTime(user.getLastTime());
            userDao.updateLoginInfo(user);
            loginLogDao.insertLoginLog(userLog);
        }
    }
}

5.配置applicationContext.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"

 ">
         <!--1. 扫描类包，把标注spring注解的类自动转化成bean，同时完成bean的注入 -->
        <context:component-scan base-package="com.zwy.dao"/>
        <context:component-scan base-package="com.zwy.service" />
        <!-- 2.定义一个使用DBCP的数据源 -->
        <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
            destroy-method="close"
            p:driverClassName="com.mysql.jdbc.Driver"

            p:password="123456"
        />
        <!-- 3.定义Spring-JDBC模板bean-->
        <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate" p:dataSource-ref="dataSource" />
        <!--4.配置事务管理器-->
        <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"
            p:dataSource-ref="dataSource"
        />
        <!--5.配置AOP,让service包下的方法处于增强事务中-->
        <aop:config proxy-target-class="true">
                <aop:pointcut expression=" execution(* com.zwy.service..*(..))" id="serviceMethod"/>
                <aop:advisor advice-ref="txAdvice" pointcut-ref="serviceMethod"/>
        </aop:config>
        <tx:advice id="txAdvice" transaction-manager="transactionManager">
            <tx:attributes>
                    <tx:method name="*"/>
            </tx:attributes>
        </tx:advice>
</beans>

6.在Junit4下测试Service的方法

package com.zwy.service;

import java.util.Date;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.zwy.domain.User;

@RunWith(SpringJUnit4ClassRunner.class)//1.基于junit4的spring测试框架
@ContextConfiguration(locations={"/applicationContext.xml"})//2.启动spring容器
public class TestService {

    @Autowired
    private UserService userService;

    @org.junit.Test
    public void userLogin(){
        boolean b1=userService.userLogin("admin", "123456");
        boolean b2=userService.userLogin("admin", "1111");
        System.out.println(b1+","+b2);
    }
    @org.junit.Test
    public void findUser(){
        User user=userService.finUserByUserName("admin");
        System.out.println(user);
    }
    @Test
    public void successLog(){
        User user=userService.finUserByUserName("admin");
        user.setLastIp("192.168.1.101");
        user.setLastTime(new Date());
        userService.successLoginLog(user);
    }
}

7.编写Web层，用到SpringMVC框架

ModelAndView 是这个包下的org.springframework.web.servlet.ModelAndView;不要搞成其他包下相同名字的类

package com.zwy.web;

import java.util.Date;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.zwy.domain.User;
import com.zwy.service.UserService;

//标注成为springMVC controller
@Controller
public class LoginController {

    @Autowired
    private UserService userService;
    //来自处理index.html
    @RequestMapping(value="/index.html")
    public String loginPage(){
        return "login";
    }
    //来自处理loginCheck.html的请求
    @RequestMapping(value="/loginCheck.html")
    public ModelAndView loginCheck(HttpServletRequest request,LoginCommod loginCommod){
        boolean isLogin=userService.userLogin(loginCommod.getUsername(), loginCommod.getPassword());
        if(isLogin){
            User user=userService.finUserByUserName(loginCommod.getUsername());
            user.setLastIp(request.getRemoteAddr());
            user.setLastTime(new Date());
            userService.successLoginLog(user);
            request.getSession().setAttribute("user", user);
            return new ModelAndView("main");
        }else {
            //参数1：逻辑视图名 参数2：数据模型 ---参数3：数据对象
            //request会以（数据模型，数据对象）的形势返回。
            return new ModelAndView("login", "error", "用户名或者密码错误！");
        }
    }

}

 package com.zwy.web;
 //封装了form表单提交的信息
 public class LoginCommod {
     private String username;
     private String password;
     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;
     }

 }

8配置web.xml

web容器自动启动Spring容器

 <?xml version="1.0" encoding="UTF-8"?>
 <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
   <!--1. 从类路径下加载spring配置文件，classpath关键字特指类路径下加载 -->
   <context-param>
           <param-name>contextConfigLocation</param-name>
           <param-value>classpath:applicationContext.xml</param-value>
   </context-param>
     <!-- 2.负责启动spring容器监听器，它将引用1处的上下文参数获得spring配置文件地址 -->
   <listener>
               <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
   </listener>
   <!-- spring MVC主控制的servlet  -->
   <servlet>
                   <!-- spring MVC的配置文件的名字 serviletName-servlet.xml -->
                   <servlet-name>zwy</servlet-name>
                   <servlet-class>    org.springframework.web.servlet.DispatcherServlet</servlet-class>
                   <!--
                       1)load-on-startup元素标记容器是否在启动的时候就加载这个servlet(实例化并调用其init()方法)。
                       2)正数的值越小，该servlet的优先级越高，应用启动时就越先加载。
                   -->
                   <load-on-startup>2</load-on-startup>
   </servlet>
   <!-- spring MVC处理的URL  -->
   <servlet-mapping>
                   <servlet-name>zwy</servlet-name>
                 <url-pattern>*.html</url-pattern>
  </servlet-mapping>
   <welcome-file-list>
     <welcome-file>index.jsp</welcome-file>
   </welcome-file-list>
 </web-app>

9.配置zwy-servlet.xml

放在WEB-INF目录下，放在src目录下报错

<?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:p="http://www.springframework.org/schema/p"
 xmlns:context="http://www.springframework.org/schema/context"
 xsi:schemaLocation="
 http://www.springframework.org/schema/beans
 http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
 http://www.springframework.org/schema/context
 http://www.springframework.org/schema/context/spring-context-3.0.xsd
 ">
 <!-- 1.扫描web包，应用Spring注解 -->
 <context:component-scan base-package="com.zwy.web" />
 <!--
     2.配置视图解析器，将ModelAndView及字符串解析为具体的页面
       prefix指定在视图名所添加的前缀
       suffix指定在视图名后添加的后缀
       InternalResourceViewResolver：通过在逻辑视图名前后加后缀
  -->
 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
         p:viewClass="org.springframework.web.servlet.view.JstlView"
         p:prefix="/WEB-INF/jsp/"
        p:suffix=".jsp"
 />
 </beans>

**注意 加入log4j日志框架，否则Spring框架会报错
