一、项目层级结构以及所需JAR包：

watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3pfeGluZG9uZw_size_16_color_FFFFFF_t_70

二、SpringMVC、Spring、Mybatis核心配置文件：

1.Mybatis：sqMapConfig.xml

2.Spring：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"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mybatis-spring="http://mybatis.org/schema/mybatis-spring"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring-1.2.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">
        <!-- 数据源dataSource sqlMapConfig.xml -->
        <!-- 加载db.properties文件 -->
    <bean  id="config" class="org.springframework.beans.factory.config.PreferencesPlaceholderConfigurer">
        <property name="locations">
            <array>
                <value>classpath:db.properties</value>
            </array>
        </property>
    </bean>
    <!-- 配置配置数据库信息（替代mybatis的配置文件conf.xml） -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
            <property name="driverClassName" value="${driver}"></property>
            <property name="url" value="${url}"></property>
            <property name="username" value="${username}"></property>
            <property name="password" value="${password}"></property>
    </bean>
        <!-- 配置mybatis sqlSessionFactory -->
        <bean id = "sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
             <property name="dataSource" ref="dataSource"/>
             <!-- 告诉spring mybatis核心配置文件的位置 -->
             <property name="configLocation" value="classpath:sqlMapConfig.xml"/>
        </bean>
        <!-- mapper动态扫描开发 -->
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
          <property name="basePackage" value="cn.skh.mapper"/>
          <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
        </bean>
        <bean name="userService" class="cn.skh.service.impl.UserServiceImpl">
           <property name="um" ref="userMapper"></property>
           <!-- userMapper就为UseMapper的对象 通过mapper动态扫描开发配置好了直接引用即可 -->
        </bean>
</beans>

3.SpringMVC：applicationContext-controller.xml：

watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3pfeGluZG9uZw_size_16_color_FFFFFF_t_70 3

三、Mapper、Service、Controller

1.mapper：

watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3pfeGluZG9uZw_size_16_color_FFFFFF_t_70 4

3.Service以及实现类:

watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3pfeGluZG9uZw_size_16_color_FFFFFF_t_70 6

2.Controller:

package cn.skh.controller;
import java.util.List;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import cn.skh.bean.User;
import cn.skh.service.UserService;
@Controller
@RequestMapping("uc")
public class UserController {
     @Autowired
     private UserService us ;
     @RequestMapping("selectAll")
     public ModelAndView select() {
         ModelAndView mv = new ModelAndView("index");
         List<User> lists = us.selectAllUser();
         mv.addObject("list", lists);//放入request域中
         return mv;
     }
     @RequestMapping("delete/{id}")
     public String deleteUser(@PathVariable("id") int id,Map<String,String>map) {
         us.deleteUser(id);
         map.put("type", "delete");
         return "success";
     }
     @RequestMapping("update")
     public String updateUser(User u,Map<String,String> map) {
         us.updateById(u);
         map.put("type", "update");
         return "success";
     }
     @RequestMapping("add")
     public String addUser(User u,Map<String,String>map) {
         us.insertOne(u);
         map.put("type", "add");
         return "success";
     }
}
