我的JSF 2.0 Web项目中有一个扩展ExceptionHandlerWrapper的异常处理程序。我遇到的问题是，在调用 handle（） 方法之前，异常出现在服务器日志中。
知道为什么会发生这种情况，以及如何解决这个问题吗？
我正在使用jBoss 7.1.2。异常处理程序 handle（） 方法如下所示：
@Override
public void handle() {
if (getUnhandledExceptionQueuedEvents() == null || !getUnhandledExceptionQueuedEvents().iterator().hasNext()) {
getWrapped().handle();
return;
}
FacesContext fc = FacesContext.getCurrentInstance();
ExternalContext externalContext = fc.getExternalContext();
Outcome outcome = Outcome.GENERAL_ERROR;
for (Iterator<ExceptionQueuedEvent> i = getUnhandledExceptionQueuedEvents().iterator(); i.hasNext();) {
ExceptionQueuedEvent event = i.next();
ExceptionQueuedEventContext context = (ExceptionQueuedEventContext) event.getSource();
Throwable throwable = context.getException();
logger.warn("Intercepting exception before it bubbles to the UI", throwable);
outcome = determineOutcome(throwable);
populateMessageForOutcome(outcome);
i.remove();
}
try {
logger.warn("GeneralUiExceptionHandler is redirecting to " + outcome.value() + " as a result of an exception");
externalContext.redirect(outcome.value());
} catch (IOException e) {
logger.error("Error while handling exceptions", e);
}
// fc.renderResponse();
// getWrapped().handle();
}

这不是由冒泡引起的。它只是由 JSF 实现的内部日志记录引起的。这在异常处理程序被命中之前已经记录下来，因此没有冒泡的方法。在您的特定示例中，它按FaceletViewHandlingStrategy#renderView()方法记录。
在您的特定情况下，使用 java.util.logging 的 Mojarra ，您可以通过在运行时类路径中logging.properties来调整日志记录。若要关闭特定日志，请添加以下条目：
javax.enterprise.resource.webcontainer.jsf.application.level = OFF
它将关闭javax.enterprise.resource.webcontainer.jsf.application记录器的所有日志记录，该记录器由其他FaceletViewHandlingStrategy使用。请注意，您可能会错过出于其他目的而记录的日志。 java.util.logging不允许对日志记录进行细粒度控制。
