public class UserController {
    
    @Autowired
    private IUserService userService;
    
    @RequestMapping("/indexs")
    public String index(){
        userService.getUserById(1);
        return "demo";
    }
}

package com.springdemo.service;

import com.springdemo.pojo.User;

public interface IUserService {
    public User getUserById(Integer userId);  
}

package com.springdemo.service.impl;

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

import com.springdemo.dao.IUserDao;
import com.springdemo.pojo.User;
import com.springdemo.service.IUserService;

@Service
public class UserServiceImpl implements IUserService{
    
    @Autowired
    private IUserDao userDao;
    @Override
    public User getUserById(Integer userId) {
        User user=userDao.selectByPrimaryKey(1);
        
        int count=userDao.deleteByPrimaryKey(1);
        
        User u=new User();
        u.setUserName("u2");
        u.setPassword("p2");
        u.setAge(22);
        userDao.insert(u);
        userDao.insertSelective(u);
        
        
        return user;
    }

}

3.整合springMVC

上面已经完成了2大框架的整合，SpringMVC的配置文件单独放，然后在web.xml中配置整合。

配置里面的注释也很详细，在此就不说了，主要是自动扫描控制器，视图模式，注解的启动这三个。

spring-servlet.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:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
       http://www.springframework.org/schema/beans/spring-beans.xsd 
       http://www.springframework.org/schema/context 
       http://www.springframework.org/schema/context/spring-context.xsd 
       http://www.springframework.org/schema/tx 
       http://www.springframework.org/schema/tx/spring-tx.xsd
          http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!-- 配置扫描的包 -->
    <!-- 自动扫描bean，把作了注解的类转换为bean -->  
    <context:component-scan base-package="com.springdemo.*" />

    <!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射  解决了@Controller注解的使用前提配置  注册DefaultAnnotationHandlerMapping和AnnotationMethodHandlerAdapter两个映射类 -->
    <mvc:annotation-driven />

    <!-- 访问静态资源 -->
    <mvc:default-servlet-handler />
    
    
    
    <!-- 视图解析器 -->
    <!-- 对模型视图名称的解析，在请求时模型视图名称添加前后缀 -->  
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/view/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
    
  <!--  <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
           <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>

           <property name="username" value="root"></property>
           <property name="password" value="root"></property>
   </bean> -->
 
    
    <!-- <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource" ref="dataSource"></property>

</beans>
