Java 异常体系设计文档

1. 异常层次设计

1.1 未检查异常 (RuntimeException)

UrlFormatException：继承自 RuntimeException，用于处理 URL 格式校验失败
- 包含无效 URL 的信息
- 提供有意义的错误消息

1.2 已检查异常 (Exception)

NetworkException：继承自 Exception，用于处理网络相关问题
- 支持链式异常 (cause)
- 提供网络操作的上下文信息

2. 异常设计原则

2.1 Checked/Unchecked 选择

UrlFormatException (Unchecked)：因为 URL 格式校验是编程错误，可以通过预检查避免，使用 Unchecked 异常更合理
NetworkException (Checked)：因为网络问题是不可预测的外部因素，使用 Checked 异常强制调用者处理

2.2 异常包装

所有异常都保留原始异常信息 (cause)
使用链式异常避免根因丢失
提供构造函数支持 cause 链

2.3 上下文信息

UrlFormatException 保存无效的 URL
NetworkException 支持传递详细的错误信息
异常消息包含足够的上下文帮助调试

3. 重试机制

3.1 指数退避策略

基础等待时间：500ms
计算公式：wait = base * 2^attempt
最大重试次数：5次
等待时间示例：500ms, 1000ms, 2000ms, 4000ms, 8000ms

4. AI 架构审计请求

作为Java架构师，请审查我的异常层次设计：Checked/Unchecked选择是否合理？异常包装是否丢失根因？日志是否包含足够上下文？
