反射，获取一个类中的静态方法。报异常看不明白

Question

@Test
public void testField1() throws Exception {
    Class<Person> personClass = Person.class;
    //创建运行时类的对象
    Person person = personClass.getDeclaredConstructor().newInstance();
    System.out.println("***********静态方法************");

    Method showDesc = personClass.getDeclaredMethod("showDesc");
    show.setAccessible(true);
    Object invoke = showDesc.invoke(personClass);
    System.out.println(invoke);
}

Answer 1

Method showDesc = personClass.getDeclaredMethod("showDesc");
    show.setAccessible(true);

私有方法，需要设置访问权限。上面调用错了吧。应该是

Method showDesc = personClass.getDeclaredMethod("showDesc");
 showDesc.setAccessible(true);
