SpringBoot利用Spring-Data-Jpa操作数据库

SpringBoot利用Spring-Data-Jpa操作数据库，是楼主花了快一周的时间所做的demo，导入Idea或者eclipse保证可以使用，不懂的地方可以看我的博文。

package com.antfin.firstboot;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class FirstbootApplication {

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