如何从没有printStackTrace的异常中获取stackTrace？

Question

Is it possible to get the whole trace from an exception without using printStackTrace() ?. One of the reasons it's because I use CheckStyle and I'm getting an ugly message. It's not enough just to call toString() . I want to get the complete message, because I needed to send me by email.

Currently, I'm doing

 StringWriter e = new StringWriter();
 exception.printStackTrace(new PrintWriter(e));

--Avoid tracing with printStackTrace() , use log4j instead.

Otherwise, I could disable CheckStyle there.

Answer 1

If you want to get error details try Apache Commons Lang api

There is a class ExceptionUtils . You can use getFullStackTrace

Answer 2

Have you tried?:

Throwable thr = e.getStackTrace();
StackTraceElement[] lines = thr.getStackTrace();

And working from there. Also, take a look at the javadocs Oli linked above

Answer 3

您可以从当前线程获取堆栈跟踪，请检查以下内容：

Thread.currentThread().getStackTrace()

Answer 4

Try this, you will be able to print stack trace with no check style error.

import org.apache.commons.lang.exception.ExceptionUtils;

String errorMessage = ExceptionUtils.getFullStackTrace(exception);  
logger.debug(errorMessage);
