【问题描述】：

有没有办法关闭每次 OmniFaces FullAjaxExceptionHandler 处理 ViewExpiredException 时发生的严重错误日志？它工作正常，我只是不想在日志中看到严重级别的错误消息。

09:11:54,875 SEVERE [org.omnifaces.exceptionhandler.FullAjaxExceptionHandler] (default task-6) FullAjaxExceptionHandler: An exception occurred during processing JSF ajax request.

更新：

我遵循了 BalusC 建议的示例 in this answer，它帮助解决了当 ViewExpiredException 不被 ServletException 包装时的日志记录问题。

（顺便说一句，this explains why ViewExpiredException 并不总是被包装。）

现在，我正在尝试处理 ViewExpiredException 被 ServletException 包裹的情况，在这种情况下，堆栈跟踪如下所示：

BalusC 的solution to handle the wrapped ViewExpiredException 使用网络过滤器，该过滤器解开异常并重新抛出根本原因。以下是 BalusC 示例中的代码：

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws ServletException, IOException {
    try {
        chain.doFilter(request, response);
    } catch (ServletException e) {
        Throwable rootCause = e.getRootCause();
        if (rootCause instanceof RuntimeException) { // This is true for any FacesException.
            throw (RuntimeException) rootCause; // Throw wrapped RuntimeException instead of ServletException.
        } else {
            throw e;
        }
    }
}

虽然过滤器很好地抛出了包装的根本原因，但不幸的是，MyAjaxExceptionHandler 没有处理根本原因（为什么会这样，我还不明白）。因此，不会抑制日志记录。

当 ViewExpiredException 被 ServletException 包裹时，我仍在寻找一种方法来抑制堆栈跟踪的记录。

现在的日志如下所示：

【问题讨论】：

  • 这是可以接受的欺骗吗？ stackoverflow.com/questions/18003309/…它不会关闭日志，而只会关闭堆栈跟踪。
  • 是的！另一个问题很有帮助，但不幸的是并没有完全解决问题。我实现了您给出的答案，并且仅当 ViewExpiredException 不是 ServletException 中的根本原因时才修复它。否则，问题仍然悬而未决。我已经更新了我的问题以反映这一点。

【解决方案1】：

当我根据 BalusC 的建议覆盖 FullAjaxExceptionHandler#logException 时：

https://stackoverflow.com/a/18017404/984932

它在ViewExpiredException 没有被ServletException 包裹的情况下消除了堆栈跟踪。为了去除堆栈跟踪的严重级别日志，我修改了BalusC的解决方案，将日志级别更改为INFO，如下：

@Override protected void logException
(
    FacesContext context,
    Throwable exception,
    String location,
    String message,
    Object... parameters
) {
    if(exception instanceof ViewExpiredException) {
        // With Throwable arg == null, no trace will be logged.
        logger.log(Level.INFO, String.format(message, location), (Throwable)null);
    }
    else {
        super.logException(context, exception, location, message, parameters);
    }
}

这是日志现在的样子：

17:01:18,487 INFO  [io.enterprizr.presentation.controller.exceptionhandler.EnterprizrAjaxExceptionHandler] (default task-18) FullAjaxExceptionHandler: An exception occurred during processing JSF ajax request. Error page '/viewExpired.xhtml' will be shown.

甜！但是，当 ViewExpiredException 包裹在 ServletException 中时，如何抑制对它的记录仍然存在问题。

【讨论】：

  • “当它被包装在 ServletException 中时。” 那么，在非 ajax 请求期间呢？使用过滤器。
  • @BalusC，是的，我实现了过滤器（我更新了原始问题以反映这一点，并展示了堆栈跟踪现在的样子）。虽然过滤器很好地抛出了包装的根本原因，但不幸的是，MyAjaxExceptionHandler 没有处理根本原因。因此，日志记录不会被抑制，我又回到了原点。
