如何从自定义反序列化程序引发自定义异常

import json

class CustomDeserializationError(Exception):
    """自定义反序列化异常"""
    def __init__(self, message):
        super().__init__(message)

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

def deserialize_person(data):
    try:
        person_data = json.loads(data)
        if 'name' not in person_data or 'age' not in person_data:
            raise CustomDeserializationError("数据格式不正确")
        if not isinstance(person_data['age'], int):
            raise CustomDeserializationError("年龄必须是整数")
        return Person(person_data['name'], person_data['age'])
    except json.JSONDecodeError:
        raise CustomDeserializationError("JSON解析失败")

# 示例数据
data = '{"name": "Alice", "age": "30"}'

try:
    person = deserialize_person(data)
    print(f"反序列化成功: {person.name}, {person.age}")
except CustomDeserializationError as e:
    print(f"反序列化失败: {e}")
