问题描述：

IDEA中，启动Spring boot项目，控制台提示org.springframework.boot.devtools.restart.SilentExitExceptionHandler$SilentExitException的异常。

解决方案：

问题出在启动入口文件 ***Application.java中，

public class XKSManagerApplicationBootstrap {

public static void main(String[] args) { //        try { //            SpringApplication.run(XKSManagerApplicationBootstrap.class, args); // 

}catch (Exception e){ // e.printStackTrace(); // }
SpringApplication.run(XKSManagerApplicationBootstrap.class, args);
log.info("++++++++++++++++++++++++++++++");
log.info("|大连同达侠刻送管理系统已启动|");
log.info("++++++++++++++++++++++++++++++");
} }

把“SpringApplication.run(ReceiveApplication.class, args);”放到try catch外面(或删掉try catch)，或在catch中不要抛出异常，就能正常显示了。

实际上在启动的时候，也没有必要try catch。

这个问题是在spring-boot-devtools引起的，但只有少数情况下会出现这种异常，如果有就按上述方法解决。

另外，spring-boot-devtools可以使开发调试时程序随时热部署，不用每次手工启停，很大程度提高了我们调试效率。
