在GWT 2.7超级开发模式下调试,是否缺少stackTrace?

[英]Debugging in GWT 2.7 Super Dev Mode, stackTrace is missing?

我刚刚从GWT 2.5.1迁移到2.7并且第一次使用SuperDev模式。 我在Chrome开发工具中启用了“JavaScript源地图”。 在Chrome控制台中,异常如下所示:

com.google.gwt.event.shared.UmbrellaException: Exception caught: For input string: "a"
  at fillInStackTrace_0_g$
  at Throwable_3_g$
  at Exception_3_g$

  at dispatchEventImpl_0_g$
  at dispatchEvent_4_g$
  at dispatchEvent_6_g$
  at apply_0_g$
  at entry0_0_g$
  at <anonymous>

OnModuleLoad我是cacthing例外:

GWT.setUncaughtExceptionHandler(new GWT.UncaughtExceptionHandler() {
        @Override
        public void onUncaughtException(Throwable e) {
            GWT.log(e);
        }
    });

我怎样才能获得stackTrace? 我试过这样的事情https://stackoverflow.com/a/24334132/1660637但无法正常工作。

您是否尝试将这些添加到gwt.xml文件中?

<set-property name="compiler.stackMode" value="emulated"/>
<set-configuration-property name="compiler.emulatedStack.recordLineNumbers" value="true"/>
<set-configuration-property name="compiler.emulatedStack.recordFileNames" value="true"/>

SuperDevMode,堆栈跟踪和GWT.log的使用存在一个未解决的问题 GWT 2.8似乎也有所改进

据我所知,如果你使用普通的java.util.logging而不是GWT.log你应该在SDM中获得堆栈跟踪。

从onModuleLoad调用以下方法。 请注意,必须使用java.util.Logging才能生效。 GWT.log无法正常处理异常。

/ ** *设置一个未捕获的异常处理程序,为SuperDevMode解包异常*(UmbrellaException)。 * / private void setUncaughtExceptionHandler(){GWT.setUncaughtExceptionHandler(new GWT.UncaughtExceptionHandler(){@ Override public void onUncaughtException(Throwable e){Throwable unwrapped = unwrap(e); BootBox.error(I18NMessages.getMessage(3774)+“\\ n \\ n“+ unwrapped”; LOGGER.log(Level.EXCEPTION,“onUncaughtException”+ e.getMessage(),unwrapped);}

     public Throwable unwrap(Throwable e)
     {
        if (e instanceof UmbrellaException)
        {
           UmbrellaException ue = (UmbrellaException) e;
           if (ue.getCauses().size() == 1)
           {
              return unwrap(ue.getCauses().iterator().next());
           }
        }
        return e;
     }
  });

}

LOGGER以下列方式创建

public static final Logger LOGGER = Logger.getLogger("Something");
