How do I get the current stack trace in Java, as in. Environment.StackTrace?

I found thread.Dumpstack () but that’s not what I wanted – I wanted to retrieve the stack trace information, not print it out.

Answer:

$\color{purple} a lot of knowledge points, really need to write out just can master!! {~}$

You can use thread.currentThread ().getStackTrace().

This returns an array of StackTraceElements that represents the current stack trace for the program.

Answer:

Thread.currentThread().getStackTrace();
Copy the code

If you don’t care about the first element of the stack, that’s fine.

new Throwable().getStackTrace();
Copy the code

If important, the location is defined for your current method.

Answer:

Thread.currentThread().getStackTrace();
Copy the code

Available as of JDK1.5.

For the older version, you can redirect the exception. PrintStackTrace () to a StringWriter () :

StringWriter sw = new StringWriter();
new Throwable("").printStackTrace(new PrintWriter(sw));
String stackTrace = sw.toString();
Copy the code

The author suggests: I care about my stack information when I have memory overflow or memory leak. If in Windows, I can directly open jVisualVM under the bin file. If in Linux, I can use Jmap to see the most occupied heap, jStack to see the stack information of threads, and can also use Arthas to analyze.
