有没有办法在重定向到错误页面之前捕获错误的堆栈跟踪（在Java中）？

标签： java stack-trace printstacktrace exceptionhandler

当我的Spring MVC应用程序发生错误时，我想发送一封电子邮件，其中包含导致错误的代码的堆栈跟踪。

我正在使用@ControllerAdvice和@ExceptionHandler注释重定向到一个方法，该方法将输出异常的堆栈跟踪并通过电子邮件发送该信息。但是，堆栈跟踪信息是针对在错误处理程序中执行的代码，而不是来自导致错误的代码。

以下是错误处理程序中输出堆栈跟踪等的代码

for(StackTraceElement stackTraceElement : Thread.currentThread().getStackTrace()) {
    logger.error(stackTraceElement);
}

这导致此输出：

但我希望这个输出（这是控制台中显示的内容）：

Thread.currentThread().getStackTrace()返回当前的堆栈跟踪（这应该不足为奇）。

如果您有对异常对象的引用（比如在局部变量e中），则可以在抛出异常时使用e.getStackTrace()来获取堆栈跟踪（实际上，当异常对象时被创造了）。这是打印异常时显示的内容。

如果您不想自己格式化堆栈跟踪，还可以使用printStackTrace(PrintStream)或printStackTrace(PrintWriter)方法，该方法将打印异常详细信息并将跟踪堆栈添加到{{1}您选择的{或PrintWriter，格式与通常打印到控制台的异常相同。
