反射中getSuperclass与getGenericSuperclass区别

相同点：都返回当前对象所表示的类的超类。
不同点：getGenericSuperclass会包含该超类的泛型。

class Person<T, V> {
}
class Teacher {
}
class Student extends Person<Student, Teacher> {
}

Class<? super Student> superclass = Student.class.getSuperclass();
 Type genericSuperclass = Student.class.getGenericSuperclass();
 System.out.println(superclass);
 System.out.println(genericSuperclass);

输出结果

class com.test.Person
com.test.Person<com.test.Student, com.test.Teacher>

getGenericSuperclass能取出指定的泛型

Type[] params = ((ParameterizedType) genericSuperclass).getActualTypeArguments();
		System.out.println((Class) params[1]);

输出结果

class com.test.Teacher
