Disconnected from the target VM, address: ‘127.0.0.1:56577‘, transport: ‘socket‘

spring boot启动的时候报这个错，一堆不靠谱的答案，根因没有显示，直接在启动类里面把run方法进行try，catch捕获打印下异常信息就能找到根因解决了。。。什么端口号啥的只是可能原因

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

变为

public static void main(String[] args) {try {SpringApplication.run(Application.class, args);} catch (Exception e) {e.printStackTrace();}}
