问题描述

限时送ChatGPT账号..

我想分析和理解某个 Java 应用程序，我认为调用图会非常有用.我如何生成一个?我正在使用 Eclipse.

I'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'm using Eclipse.

推荐答案

获取调用堆栈

1) 如果您可以调试，应用程序只需放置一个断点(双击代码的左边距)并等待它停止.如果您不在那里，请转到 Debug Perspective，然后打开 Call stack View/Panel.它有调用堆栈:)

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're not there, and open the Call stack View/Panel. It has the call stack :)

2) 如果您想在某处打印此堆栈跟踪，请使用异常:

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

Exception aux = new Exception("I'm here"); // not for throwing!
aux.printStackTrace(); // if you want it in stdout

或

Exception aux = new Exception("I'm here"); // not for throwing!
StringWriter sw = new StringWriter();
aux.printStackTrace(new PrintWriter(sw));
String result = sw.toString(); // if you want it in a string

获取方法引用

您可以通过右键单击引用"、工作区"来获取对方法的所有引用.它将搜索您当前打开的项目中的所有调用.非常非常有用.

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.
