1、新建springboot项目结构

2、准备数据库脚本,新建test数据库和user表,并模拟一些数据。

3、利用easycode插件把数据库表自动生成controller、service、dao、mapper、entity等文件和目录。



4、在springboot启动类上添加对dao层包的扫描
package com.test.springbootmybatis;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@MapperScan(basePackages = "com.test.springbootmybatis.dao")
@SpringBootApplication
public class SpringbootMybatisApplication {
public static void main(String[] args) {
SpringApplication.run(SpringbootMybatisApplication.class, args);
}
}
5、启动项目,测试访问
