我们使用 Spring Boot 2 与 Actuator 和 Prometheus 来显示 Grafana 仪表板。我想添加 Apache Http Client PoolingHttpClientConnectionManager 指标来报告连接池统计信息。我看到它已添加到 micrometer-core:1.3.0 ( https://github.com/micrometer-metrics/micrometer/pull/1223 )。但是，我在 /actuator/metrics 或 /actuator/prometheus 端点中没有看到任何相关指标。我尝试更新 pom.xml 中的依赖项：

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.6.RELEASE</version>
        <relativePath/>
        <!-- lookup parent from repository -->
    </parent>
...
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-core</artifactId>
            <version>1.4.2</version>
        </dependency>
        <dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-registry-prometheus</artifactId>
            <version>1.4.2</version>
        </dependency>
