Spring Springmvc mybatis整合思路：Springmvc属于Spring体系的不用特意去整合，但是在业务开发的时候通常将Springmvc.XML与Spring.xml配置分开处理，是为了降低业务的耦合度，Springmvc负责请求分发，Spring.xml配置事务,整合其他框架。spring与mybatis整合参考文档

启动Web项目的时候，Tomcat首先会读取web.xml文件的信息，启动全局Spring父容器与Springmvc子容器

    
    
    
    
        contextConfigLocation
        classpath:spring.xml
    
    
        org.springframework.web.context.ContextLoaderListener
    
    
    
        springmvc
        org.springframework.web.servlet.DispatcherServlet
        
            contextConfigLocation
            classpath:springmvc.xml
        
    
    
        springmvc
        /
    

Spring.xml配置信息，其中配置了数据库连接池，以及整合Mybatis的配置

    
    
    
        
        
        
        
        
        
    



    
    
    
        
         
service层
 
package com.cqupt.service;

import com.cqupt.entity.User;

import java.util.List;

public interface UserService {
    public List list();
}

 
package com.cqupt.service.impl;

import com.cqupt.entity.User;
import com.cqupt.repository.UserMapper;
import com.cqupt.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserMapper userMapper;

    @Override
    public List list() {
        return userMapper.list();
    }
}

 
Dao层
 
package com.cqupt.Dao;

import com.cqupt.entity.User;

import java.util.List;

public interface UserMapper {
    public List list();
}

 




    
        select * from user
