java开发软件eclipse图片,如何生成Java调用图，基于Eclipse的解决方案

I&＃39;d like to analyze and understand a certain Java app and I think a call graph would be very useful. How do I generate one? I&＃39;m using Eclipse.

Getting callstack

1) If you can debug the application simply put a breakpoint (double click over the left margin of the code) and wait it to stop. Go to Debug Perspective if you&＃39;re not there, and open the Call stack View/Panel. It has the call stack :)

2) If you want to print this stack trace somewhere use an Exception:

Exception aux &＃61; new Exception("I&＃39;m here"); // not for throwing!

aux.printStackTrace(); // if you want it in stdout

or

Exception aux &＃61; new Exception("I&＃39;m here"); // not for throwing!

StringWriter sw &＃61; new StringWriter();

aux.printStackTrace(new PrintWriter(sw));

String result &＃61; sw.toString(); // if you want it in a string

Obtaining method references

You can obtain all references to a method by right-clicking, References, Workspace. It will search all callings in your current open projects. Very very useful.

Profiling an app

(thanks those who had answered the profiler option)

Eclipse TPTP provides profiling:
