springboot 整合 Mybatis mysql

1.加入mybatis需要依赖

        
            org.mybatis.spring.boot
            mybatis-spring-boot-starter
            1.3.1
        

        
        
            mysql
            mysql-connector-java
        



		
			
				src/main/java
				
					**/*.xml
				
			
		
	

2.添加mysql配置

#mysql 配置
spring.datasource.url= jdbc:mysql://localhost:3306/hz_subway?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=root
        
#mybatis配置
mybatis.mapper-locations=com/seage/dao/*.xml
mybatis.type-aliases-package=com.seage.entity

3.修改启动类，扫描mapper配置文件

4.简单controller（service dao层省略）

package com.test.controller;

import com.test.entity.User;
import com.test.service.TestService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

/**
 * @author gdl
 * @date 2018/12/18 17:04
 */
@RequestMapping("test")
@Controller
public class TestController {
    @Autowired
    TestService testService;

    @RequestMapping("index")
    public String index(){
        return "index";
    }


    @RequestMapping("/getUser")
    @ResponseBody
    public User getUser(){
        return  testService.getUsers();
    }
}

5.浏览器访问，访问成功
