我想避免模拟类的getClass()方法,但似乎无法找到它的任何方法.我正在尝试测试一个将HashMap中的对象类类型存储到以后要使用的特定方法的类.一个简短的例子是:

public class ClassToTest {
    /** Map that will be populated with objects during constructor */
    private Map<Class<?>, Method> map = new HashMap<Class<?>, Method>();

    ClassToTest() {
        /* Loop through methods in ClassToTest and if they return a boolean and 
           take in an InterfaceA parameter then add them to map */
    }

    public void testMethod(InterfaceA obj) {
        final Method method = map.get(obj.getClass());
        boolean ok;
        if (method != null) {
             ok = (Boolean) method.invoke(this, obj);
        }
        if (ok) {
            obj.run();
        }
    } …
