如何在Console上停止打印异常堆栈跟踪？ [英] How to stop printing exception stack trace on Console?

问题描述

我编写了一个servlet来处理我的Web应用程序中发生的异常，并将它们映射到web.xml中

I wrote a servlet to handle the exceptions occurring in my web app and mapped them in web.xml

    <error-page>
      <exception-type>java.lang.Exception</exception-type>
      <location>/exceptionHandler</location>
    </error-page>

以下是我在异常处理servlet中所做的 service 方法：

Here is what I have done in the Exception Handling servlet service method:

@Override
    protected void service(HttpServletRequest req, HttpServletResponse arg1)
            throws ServletException, IOException {
         Object attribute = req.getAttribute("javax.servlet.error.exception");
         if(attribute instanceof  SocketException){
            // don't do anything 
         }else{
          super.service(req, arg1);
         }
    }.

问题：

上述方法无效，堆栈跟踪正在打印到控制台。当用户请求某些内容然后关闭其浏览器时会发生这种情况。

The above approach is not working and the stack trace is printing to the console. This occurs when the user requests something and then closes their browser.

问题：

每当发生 SocketException 时，如何停止将printtrace打印到JBoss控制台？

How do I stop printing the stacktrace to the JBoss console whenever a SocketException occurs?

原因为此：

我想避免在最后看到所有日志的 SocketException 因为我对这些信息无能为力。

I want to avoid seeing all of the log's SocketExceptions at the end of th day because I can't do anything with that information.

推荐答案

而不是添加 java。您的web.xml中的lang.Exception 为什么不尝试在web.xml本身添加套接字异常，如下所示

Instead of adding java.lang.Exception in your web.xml why won't you just try to add socket exception in web.xml itself like below

<error-page>
  <exception-type>java.net.SocketException</exception-type>
  <location>/exceptionHandler</location>
</error-page>

并且只在您的servlet中执行任何操作
或而是添加一个空的jsp文件，比如

and just do nothing in your servlet Or instead add a empty jsp file like

<error-page>
  <exception-type>java.net.SocketException</exception-type>
  <location>/error.jsp</location>
</error-page>
