spring-boot - Spring Boot 不会从类路径 (cloudwatch) 中获取 Micrometer Registry

Question

我在类路径上使用带有 micrometer-spring-legacy:1.1.4 和 micrometer-registry-cloudwatch:1.1.4 的 Spring Boot 1.5。根据docs它应该自动获取这个注册表:

Having a dependency on micrometer-registry-{system} in your runtime classpath is enough for Spring Boot to configure the registry.

但是，当我在应用程序启动时查看已注册的 Spring bean 时，只有“simpleMeterRegistry”(我认为这是默认设置)。

为什么它不接收 CloudWatchMeterRegistry ？如何排除故障？谢谢!!!

来自日志:

更新

我看到有 CloudWatchMetricAutoConfiguration我希望它能产生 CloudWatchMetricWriter Bean 但是没有这样的bean。它还应该创建一个 AmazonCloudWatchAsync bean 但它没有 - 我们拥有的唯一“amazon”bean 是 amazonS3 .

可能的原因

我发现 micrometer-spring-legacy:1.1.4有包裹 io.micrometer.spring.autoconfigure.export.<system>与 <system>MetricsExportAutoConfiguration , <system>Properties , <system>PropertiesConfigAdapter对于每个受支持的系统 - 但不是 CloudWatch。这些类使 *Registry 可用作 Spring bean，并且由于不支持 cloudwatch 注册表，因此不能用作 spring bean。

Answer 1

所以问题是我缺少 CloudWatch 的 micrometer-spring 集成，由于其依赖性，它不包含在 micrometer-spring-legacy 中。相反，它存在于 Spring Cloud AWS 存储库中，即 in the package org.springframework.cloud.aws.autoconfigure.metrics的 spring-cloud-aws-autoconfigure图书馆。

参见 spring-projects/spring-boot#11276背景。

但是 spring-cloud-aws-autoconfigure 2 需要 Boot 2.x，最新的 Boot 1.5 是 1.2.3，它缺少 CloudWatch 指标集成。因此，唯一的选择是复制、粘贴、调整其 CloudWatchMetricsExportAutoConfiguration。
