RetryHelper

智能重试器 — 支持退避策略（固定/线性/指数）+ 抖动 + 断路器 + 降级 + 超时。

核心功能

退避策略：固定间隔 / 线性增长 / 指数退避
抖动类型：Full（全抖动）/ Equal（等量）/ Decorrelated（去相关）/ None（无）
断路器：Closed → Open → HalfOpen 三态自动切换
超时控制：单次执行超时 + 总超时
降级 Fallback：重试耗尽后执行备选逻辑
重试回调：每次失败后可执行自定义逻辑
同步 + 异步：完整的同步/异步 API，支持 CancellationToken
扩展方法：Func<T>.Retry() / Func<T>.RetryWith(policy) 等链式调用

快速开始

基础用法

// 使用默认策略（3次，指数退避 1s→30s，全抖动）
var result = RetryPolicy.Default.Execute(() => CallRemoteService());

// 自定义策略
var policy = RetryPolicy
    .Build()
    .WithMaxRetries(5)
    .WithExponentialBackoff(TimeSpan.FromSeconds(1), TimeSpan.FromMinutes(1))
    .WithJitter(JitterType.Full)
    .When<HttpRequestException>()
    .When<TimeoutException>()
    .Build();

var result = policy.Execute(() => CallRemoteService());

异步使用

var result = await policy.ExecuteAsync(async ct =>
{
    return await httpClient.GetAsync(url, ct);
});

断路器

var policy = RetryPolicy
    .Build()
    .WithCircuitBreaker(failures: 3, breakDuration: TimeSpan.FromSeconds(30))
    .WithOperationKey("PaymentService")
    .OnCircuitStateChanged((s, e) =>
    {
        Console.WriteLine($"断路器: {e.OldState} → {e.NewState}");
    })
    .Build();

降级 Fallback

var result = policy.ExecuteWithFallback(
    () => CallPrimaryService(),
    report => CallBackupService()
);

扩展方法

// 使用默认策略重试
var result = (() => CallService()).Retry();

// 使用自定义策略
var result = (() => CallService()).RetryWith(policy);

// 异步
var result = await (() => CallServiceAsync()).RetryAsync();
