springboot+mybatis+mysql+thymeleaf 实现最基本数据库操作demo

使用springboot框架引入mybatis连接mysql数据库（xml和注解两种方式实现sql语句），最后用thymeleaf展示数据。

package com.example.demo;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@MapperScan（“com.example.demo.dao“）// mybatis扫描路径，针对的是接口Mapper类
public class DemoApplication {



	public static void main（String[] args） {
		SpringApplication.run（DemoApplication.class args）;
	}



}
