Question

我需要获取引发异常的类名和方法名。我怎样才能做到这一点？提前谢谢。

我的代码：

private void setErrorDetails(final Throwable cause) {
    for (final StackTraceElement ste : cause.getStackTrace()) {
        System.out.println(ste.getClassName()); 
        System.out.println(ste.getMethodName()); 
    }
}

通过这段代码，我可以得到一个类名和方法名列表。其中，我怎样才能得到抛出异常的方法和类名

我也试过这个。

 final StackTraceElement[] stackTrace = cause.getStackTrace();
    if ((stackTrace != null) && (stackTrace.length > 1)) {
                    final StackTraceElement stElement = stackTrace[0];

                    this.className = stElement.getClassName();
                    this.methodName = stElement.getMethodName();}

这是打印的堆栈跟踪。

我已经打印了堆栈跟踪。我需要得到16：01：24,110。

Answer 1

实际抛出初始异常的方法是堆栈跟踪的根本原因中的第一个元素：

private void setErrorDetails(final Throwable cause)
{
     Throwable rootCause = cause;
     while(rootCause.getCause() != null &&  rootCause.getCause() != rootCause)
          rootCause = rootCause.getCause();

    System.out.println(rootCause.getStackTrace()[0].getClassName()); 
    System.out.println(rootCause.getStackTrace()[0].getMethodName()); 
    }
}

Answer 2

This article显示了如何使用LogBack过滤掉日志中不希望在堆栈跟踪中看到的包。

同样的原则应该适用于你的java代码，你只需要在类名上构造过滤器。
