使用 Resilience4j 重试的 HttpSender

HttpSender 是一个用于 HTTP 客户端的接口，这些客户端用于基于 HTTP 的指标发布。它有两个实现：

• HttpUrlConnectionSender: 基于 HttpURLConnection 的 HttpSender

• OkHttpSender: 基于 OkHttp 的 HttpSender

Micrometer 不支持重试，但你可以使用 Resilience4j 的重试功能来装饰它，如下所示：

@Bean
	public DatadogMeterRegistry datadogMeterRegistry(DatadogConfig datadogConfig, Clock clock) {
		return DatadogMeterRegistry.builder(datadogConfig)
				.clock(clock)
				.httpClient(new RetryHttpClient())
				.build();
	}

	private static class RetryHttpClient extends HttpUrlConnectionSender {

		private final RetryConfig retryConfig = RetryConfig.custom()
				.maxAttempts(2)
				.waitDuration(Duration.ofSeconds(5))
				.build();

		private final Retry retry = Retry.of("datadog-metrics", this.retryConfig);

		@Override
		public Response send(Request request) {
			CheckedFunction0<Response> retryableSupplier = Retry.decorateCheckedSupplier(
					this.retry,
					() -> super.send(request));
			return Try.of(retryableSupplier).get();
		}

	}
