[英]Debugging in GWT 2.7 Super Dev Mode, stackTrace is missing?
我剛剛從GWT 2.5.1遷移到2.7並且第一次使用SuperDev模式。 我在Chrome開發工具中啟用了“JavaScript源地圖”。 在Chrome控制台中,異常如下所示:
com.google.gwt.event.shared.UmbrellaException: Exception caught: For input string: "a"

OnModuleLoad我是cacthing例外:
GWT.setUncaughtExceptionHandler(new GWT.UncaughtExceptionHandler() {
@Override
public void onUncaughtException(Throwable e) {
GWT.log(e);
}
});
我怎樣才能獲得stackTrace? 我試過這樣的事情https://stackoverflow.com/a/24334132/1660637但無法正常工作。
您是否嘗試將這些添加到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"/>
從onModuleLoad調用以下方法。 請注意,必須使用java.util.Logging才能生效。 GWT.log無法正常處理異常。
/ ** *設置一個未捕獲的異常處理程序,為SuperDevMode解包異常*(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以下列方式創建
public static final Logger LOGGER = Logger.getLogger("Something");
