1、如果使用spring， 可以使用以下方式获得spring context中的所有的类：

public class GameReflect implements ApplicationContextAware {
	public ApplicationContext applicationContext;

@Override
	public void setApplicationContext(ApplicationContext applicationContext)
			throws BeansException {
		this.applicationContext = applicationContext;
	}
public void getAllClass(){
        applicationContext.getBeansOfType(GameBaseAction.class);
}
}

2、除此之外，也可以从classloader中使用一种hack方式获得所有的类:

package cn.joylab.service;

import java.lang.reflect.Field;
import java.util.Vector;

public class ClassLoaderTest extends GameBaseManagerTestCase {
	@org.junit.Test
	public void test1() {
		try {
			Field f = ClassLoader.class.getDeclaredField("classes");
			f.setAccessible(true);

			ClassLoader classLoader = Thread.currentThread().getContextClassLoader();

			Vector<Class> classes = (Vector<Class>) f.get(classLoader);
			for (Class c : classes) {
				System.out.println(c);
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

}
