问题
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 ReceiveApplication {private final static Log logger = LogFactory.getLog(ReceiveApplication.class);public static void main(String[] args) {try {SpringApplication.run(ReceiveApplication.class, args);logger.info("Receive Service项目启动完成");} catch (Exception e){e.printStackTrace();}}
}
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。
