java泛型得到T.class

import java.lang.reflect.ParameterizedType;

public class Test {
	public Class getTClass() {
		return (Class) ((ParameterizedType) getClass()
				.getGenericSuperclass()).getActualTypeArguments()[0];
	}

	public void test() {
		System.out.println(getTClass());
	}

	public static void main(String s[]) {
		(new Test() {
		}).test();
	}

}

输出结果:

class java.lang.String
