如何配置spring-boot micrometer 推入elasticsearch？

Question

我有一个 spring-boot 2 应用程序，它公开了它的执行器端点。这些值，我想导出到现有的 elasticsearch 实例。因此我使用了以下内容：

pom.xml

...

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.5.RELEASE</version>
    </parent>

    <properties>
        <java.version>11</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-registry-elastic</artifactId>
            <version>1.2.0</version>
        </dependency>

        ...

    </dependencies>

application.yml

management:
  metrics:
    export:
      elastic:
        enabled: true
        host: http://192.168.23.43:9200/
        auto-create-index: true
        index: metrics
        step: 1m

启动应用程序时，POST 抛出以下异常：

我确保 elasticsearch 可以访问，但事实上，它试图 post 反对 /，这让我感到困惑。我错过了什么？

Answer 1

由于某种原因，micrometer-registry-elastic 的版本导致了问题。降级到版本 1.1.4 后一切正常。
