如何获取我的应用程序在JAVA中加载的所有类

Question

How to get all the classes loaded by my application running in integrated weblogic server . I used java -verbose:class and created a javaagent that returns .getAllLoadedClasses() using Instrumentation package . Both returns a large set of results mainly from packages java.* and sun.* but no class from my app was present in the output. How to get the classes loaded by my app. I am a beginner. Please help.

Answer 1

You can try something with following

Reflections reflections = new Reflections(ClasspathHelper
                          .forClass(Object.class),new SubTypesScanner(false));
Set<String> classList =reflections.
                         getStore().getSubTypesOf(Object.class.getName())

FYI: Reflections

Answer 2

You might try to experiment with java.lang.ClassLoader . This class has an internal attribute classes of type Vector . If you use reflection then you can access the loaded classes of its classloader-instance only. And of course you can also go up the ClassLoader-hierarchy to ask the parents of application classloader.
