App.java
package com.lfy.cn.springbootTest; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; /** * Hello world! * */ @SpringBootApplication public class App { public static void main( String[] args ) { SpringApplication.run(App.class,args); } }
运行结果：
在App.java中以鼠标邮件启动springboot。
