三、SpringBoot 整合 SpringMVC+MyBatis

package com.taiping;

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

@SpringBootApplication
@MapperScan("com.taiping.dao") //@MapperScan 用户扫描MyBatis的Mapper
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}
