Breakpoint at "throw new SilentExitException()" in Eclipse + Spring Boot
提问by Bruno De Freitas Barros
Everytime I run my Spring Boot project on debug mode in Eclipse IDE (Spring Tool Suite), the thread stops at "throw new SilentExitException();" line even without a breakpoint.
每次我在 Eclipse IDE（Spring 工具套件）中以调试模式运行 Spring Boot 项目时，线程都会在“throw new SilentExitException();”处停止。即使没有断点也行。
Some solution to avoid this behavior?
避免这种行为的一些解决方案？
org.springframework.boot.devtools.restart.SilentExitExceptionHandler.exitCurrentThread() (line 53):
org.springframework.boot.devtools.restart.SilentExitExceptionHandler.exitCurrentThread()（第 53 行）：
public static void exitCurrentThread() {
throw new SilentExitException();
}
This starts happening after upgrade to 1.3.0 Milestones.
这在升级到 1.3.0 里程碑后开始发生。
Spring Tool Suite Version: 3.7.0.RELEASE Build Id: 201506290649 Platform: Eclipse Luna SR2 (4.4.2)

This is unfortunately a know issue with the new spring-boot-devtoolsmodule (see https://github.com/spring-projects/spring-boot/issues/3100). We use this trick to kill the main thread so that we can replace it with a re-loadable version. So far I've not found a way to prevent the debug breakpoint from triggering.
不幸的是，这是新spring-boot-devtools模块的一个已知问题（请参阅https://github.com/spring-projects/spring-boot/issues/3100）。我们使用这个技巧杀死主线程，以便我们可以用可重新加载的版本替换它。到目前为止，我还没有找到防止触发调试断点的方法。
For now, you can toggle the "suspend execution on uncaught exceptions" checkbox in Java -> Debug preferences to prevent it from happening.
现在，您可以在 Java -> Debug 首选项中切换“在未捕获的异常上暂停执行”复选框以防止它发生。

As Eclipse on Debug mode already allows limited hotpatching, I find the reloader to be counterproductive most of the time and so I decided to disable it by:
由于调试模式下的 Eclipse 已经允许有限的热修补，我发现重新加载器在大多数情况下会适得其反，因此我决定通过以下方式禁用它：
System.setProperty("spring.devtools.restart.enabled", "false");
参考：https: //docs.spring.io/spring-boot/docs/current/reference/html/using-boot-devtools.html#using-boot-devtools-restart-disable
Since that exception is thrown by the reloader, this also solves this issue. Note that you'll have to use the System.setPropertymethod instead of setting it in application.properties.
由于该异常是由重新加载器抛出的，因此这也解决了这个问题。请注意，您必须使用该System.setProperty方法而不是将其设置在application.properties.

Try to run devtools at scope runtime:
尝试在范围运行时运行 devtools：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<scope>runtime</scope>
</dependency>

Add the property as a VM argument in the configuration like:
在配置中添加属性作为 VM 参数，例如：
That way you don't have to change your code, as it is the case when using:
这样您就不必更改代码，就像使用时一样：
System.setProperty("spring.devtools.restart.enabled", "false");

My workaround:
我的解决方法：
public static void main(String[] args) {
try {
SpringApplication.run(App.class, args);
} catch (Throwable e) {
if(e.getClass().getName().contains("SilentExitException")) {
LOGGER.debug("Spring is restarting the main thread - See spring-boot-devtools");
} else {
LOGGER.error("Application crashed!", e);
}
}
}
It doesn't matter that we ignore the SilentExitExceptionbecause the devtools are just restarting the instance with a SilentExitExceptionwhich isn't very silent. This try block will silence it...
我们忽略 并不重要，SilentExitException因为 devtools 只是用一个SilentExitException不是很安静的a 重新启动实例。这个 try 块将使其静音...
I had to use text matching on the class as the SilentExitExceptionis private in SilentExitExceptionHandler.
我不得不使用文本匹配的类作为SilentExitException在私人SilentExitExceptionHandler。
It doesn't solve your problem with the breakpoint...
它不能解决您的断点问题...
