17-SpringBoot构建微服务实战
17.1 编写服务启动入口
package com.clsaa.edu.springboot;
import com.clsaa.edu.springboot.bean.Product;
import com.clsaa.edu.springboot.mapper.ProductMapper;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;
/**
* Created by Egg on 2017/2/28.
*/
@SpringBootApplication
public class App {
public static void main(String[] args) {
ConfigurableApplicationContext context = SpringApplication.run(App.class,args);
}
}
