如何通过属性控制方法行为？

def my_decorator(func):
    def wrapper(*args, **kwargs):
        # 在这里添加您的自定义行为
        result = func(*args, **kwargs)
        # 在这里添加您的自定义行为
        return result
    return wrapper

class MyClass:
    def __init__(self, use_decorator=False):
        self.use_decorator = use_decorator

    def my_method(self, *args, **kwargs):
        print("This is my method.")

    @property
    def my_method_with_decorator(self):
        if self.use_decorator:
            return my_decorator(self.my_method)
        else:
            return self.my_method

obj1 = MyClass(use_decorator=True)
obj1.my_method_with_decorator() # 输出 "This is my method." 并使用装饰器修改行为

obj2 = MyClass(use_decorator=False)
obj2.my_method_with_decorator() # 输出 "This is my method." 并不使用装饰器修改行为
