将我的应用程序（堆栈弹簧靴，骆驼，hystrix）从弹簧靴1.5迁移到弹簧靴2之后。我无法在/ actuator / prometheus中显示hystrix指标。
正如许多解决方案和教程所建议的那样，我确保我具有以下依赖性
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-registry-prometheus</artifactId>
<version>${micrometer-version}</version>
</dependency>
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-core</artifactId>
<version>${micrometer-version}</version>
</dependency>
并添加了以下配置类，我已经确定它已被实例化，因为我已经在spring boot自动配置日志中进行了检查：
import io.micrometer.core.instrument.binder.hystrix.HystrixMetricsBinder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class HystrixMetricsConfig {
@Bean
HystrixMetricsBinder registerHystrixMetricsBinder() {
return new HystrixMetricsBinder();
}
}
为了避免假设此类教程/答案在定义上是正确的，我从头开始设置了一个简单的spring boot项目，其中包含一个简单的控制器，hystrix和上述依赖性，并且指标确实出现在/ actuator / prometheus中，而无需执行其他步骤。
与简单项目相比，我的应用程序具有更多的依赖关系，因此我认为可能有其他事情要覆盖/禁用指标绑定。

除了被告知实际问题是什么之外，我还在努力了解如何解决此类问题。是否可以激活任何千分尺/弹簧启动日志（自动配置报告除外）以了解发生了什么？
最佳答案
在遵循整个自定义hystrix度量标准绑定过程之后，我最终发现，至少在原则上，所有内容都正确地绑定了。
然后，我尝试在首次执行hystrix命令时触发一个断点，以检查注册表和发布者的情况。在方法中放置断点
HystrixMetricsPublisherThreadPool getPublisherForThreadPool(HystrixThreadPoolKey threadPoolKey, HystrixThreadPoolMetrics metrics, HystrixThreadPoolProperties properties)
在
HystrixMetricsPublisherFactory类的基础上，我发现HystrixPlugins实例与设置发布者的时间有所不同。检查完应用程序的所有代码后，我发现，要设置自定义事件通知程序，实例将被重置。
@EventListener(ApplicationReadyEvent.class)
public void doAfterStartup() {
Hystrix.reset();
registerCustomHystrixEventNotifier(circuitBreakerHystrixEventNotifier);
logger.info("hello world, application started up");
}
然后，我修改了该方法以注册事件通知程序，而无需重置之前配置的自动配置，并且hystrix指标现在显示在prometheus端点中。
关于java - 将应用程序迁移到Spring Boot 2之后，无法将hystrix指标公开给/actuator/prometheus，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/57844565/
