三、配置

　　1.打开web.xml文件，添加如下配置

　　　　Web程序整合SpringMvc框架

<?xml version="1.0" encoding="UTF-8"?>
<web-app 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xsi:schemaLocation="

          <param-value>classpath:ApplicationContext-*.xml</param-value>
      </context-param>
      <listener>
          <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
      
      
      <!-- 配置springmvc前端控制器 -->
      <servlet>
          <servlet-name>springMvc</servlet-name>
          <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
          <init-param>
              <!-- 配置初始化参数：指定SpringMvc核心配置文件的位置 -->
              <param-name>contextConfigLocation</param-name>
              <param-value>classpath:SpringMvc.xml</param-value>
          </init-param>
          <!-- tomcat启动时就加载这个servlet -->
          <load-on-startup>0</load-on-startup>
      </servlet>
      <servlet-mapping>
          <servlet-name>springMvc</servlet-name>
          <!-- / 表示拦截所有请求，不包括jsp     /* 表示拦截所有请求，包括jsp -->
          <url-pattern>/</url-pattern>
      </servlet-mapping>
      
      <!-- 配置post乱码过滤器 -->
      <filter>
          <filter-name>encodingFilter</filter-name>
          <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
          <init-param>
              <param-name>encoding</param-name>
              <param-value>utf-8</param-value>
          </init-param>
      </filter>
      <filter-mapping>
          <filter-name>encodingFilter</filter-name>
          <url-pattern>/</url-pattern>
      </filter-mapping>
  
</web-app>

　　2.打开config下的ApplicationContext-service.xml，添加如下配置

　　　　spring框架自身的配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context" 
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:aop="http://www.springframework.org/schema/aop" 
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/aop 
        http://www.springframework.org/schema/aop/spring-aop-4.0.xsd 
        http://www.springframework.org/schema/tx 
        http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
        http://www.springframework.org/schema/util 
        http://www.springframework.org/schema/util/spring-util-4.0.xsd">

    <!-- 添加@Service注解扫描 -->
    <context:component-scan base-package="cn.hpe.service"></context:component-scan>
    
</beans>

　　3.打开config下的ApplicationContext-dao.xml，添加如下配置

　　　　spring整合Mybatis框架

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context" 
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:aop="http://www.springframework.org/schema/aop" 
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/aop 
        http://www.springframework.org/schema/aop/spring-aop-4.0.xsd 
        http://www.springframework.org/schema/tx 
        http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
        http://www.springframework.org/schema/util 
        http://www.springframework.org/schema/util/spring-util-4.0.xsd">

    <!-- 引入db属性文件 -->
    <context:property-placeholder location="classpath:db.properties"/>
    
    <!-- 配置数据源 -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="${jdbc.driver}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
        <property name="maxActive" value="20"/>
        <property name="maxIdle" value="5"/>
    </bean>
    
    <!-- 配置mbatis会话工厂 -->
    <bean class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="configLocation" value="classpath:SqlMapConfig.xml"/>
    </bean>
    
    <!-- 配置mapper包扫描 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="cn.hpe.dao"></property>
    </bean>
    

</beans>

　　4.打开config下的ApplicationContext-trans.xml，添加如下配置：

　　　　将事务交给spring处理，这里使用的是注解的方式，也可以使用AOP的方式。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context" 
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:aop="http://www.springframework.org/schema/aop" 
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/aop 
        http://www.springframework.org/schema/aop/spring-aop-4.0.xsd 
        http://www.springframework.org/schema/tx 
        http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
        http://www.springframework.org/schema/util 
        http://www.springframework.org/schema/util/spring-util-4.0.xsd">

    <!-- 配置事务管理器 -->
    <bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>
    
    <!-- 配置@Transactional注解驱动 -->
    <tx:annotation-driven/>
    
    
</beans>

　　5.打开config下的SpringMvc.xml，添加如下配置：

　　　　SpringMvc框架自身配置

<?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"
    xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" 
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
        http://code.alibabatech.com/schema/dubbo 
        http://code.alibabatech.com/schema/dubbo/dubbo.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-4.0.xsd">
    
    <!-- 配置@Controller注解扫描 -->
    <context:component-scan base-package="cn.hpe.controller"></context:component-scan>
    
    <!-- 配置注解驱动，有了这个，就能自动配置HandlerMapping和HandlerAdapter -->
    <mvc:annotation-driven></mvc:annotation-driven>
    
    
    <!-- 配置视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
        <property name="order" value="0"/>
    </bean>
    
</beans>

　　6..打开config下的db.properties，添加如下配置：

　　　　数据库、用户名密码根据自己情况修改

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test?characterEncoding=utf-8
jdbc.username=lemodk
jdbc.password=lemodk

　　7.SqlMapConfig.xml不需要添加配置，但是不能没有

至此，配置就结束了，下面开始编写后台测试代码：

四、后台测试代码

　后台代码整体结构：

　　User.java

package cn.hpe.pojo;

public class User {

    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;
    }
    @Override
    public String toString() {
        return "User [username=" + username + ", password=" + password + "]";
    }
    
    
}

　　UserMapper.java

package cn.hpe.dao;

import cn.hpe.pojo.User;

public interface UserMapper {

    /**
     * 登录验证
     * @param user 包含用户名和密码的user对象
     * @return user 存在，则返回一行记录的所有信息对象。否则为null
     */
    User getOneByLogin(User user);
}

　　UserMapper.xml

<?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="cn.hpe.dao.UserMapper">

    <select id="getOneByLogin" parameterType="cn.hpe.pojo.User" resultType="cn.hpe.pojo.User">
        select * from user where username=#{username} and password=#{password}
    </select>

</mapper>

　　IUserService.java-----------接口

package cn.hpe.service;

import cn.hpe.pojo.User;

public interface IUserService {

    User login(User user);
}

　　UserServiceImpl.java

package cn.hpe.service;

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

import cn.hpe.dao.UserMapper;
import cn.hpe.pojo.User;

@Service(value="userService")
public class UserServiceImpl implements IUserService {
    
    
    @Autowired
    private UserMapper userMapper;

    @Override
    public User login(User user) {
        return userMapper.getOneByLogin(user);
        
    }

}

　　UserController.java

package cn.hpe.controller;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import cn.hpe.pojo.User;
import cn.hpe.service.IUserService;

@Controller
@RequestMapping("/user")
public class UserController {
    
    @Resource(name="userService")
    private IUserService userService;

    @RequestMapping("/login")
    public String login(User user,Model model) {
        
        User reUser = userService.login(user);
        if(reUser!=null){
            model.addAttribute("flag", "1");
        }
        return "success";
    }
}

最后附上测试项目源码：

这是最原始的配置方式，所以下载解压，导入工作空间后，需要修改一些本测试项目的配置：jdk版本、tomcat等
