import java.lang.reflect.ParameterizedType;public class Test<T> {public Class<T> getTClass() {return (Class<T>) ((ParameterizedType) getClass().getGenericSuperclass()).getActualTypeArguments()[0];}public void test() {System.out.println(getTClass());}public static void main(String s[]) {(new Test<String>() {}).test();}}

输出结果:
