Kafka消费者指标从Spring Boot 2.2.2升级到2.3.0

• 我们正在为我们的kafka broker（kafka Version2.1.1)使用Red Hat AMQ Streams
• 我们在环境中唯一更改的是Spring Boot版本（以及自动拉入/更新的依赖项），以重新创建此问题

以下是更改前的构建。gradle.kts：

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

plugins {
    id("org.springframework.boot") version "2.2.2.RELEASE"
    id("io.spring.dependency-management") version "1.0.9.RELEASE"
    kotlin("jvm") version "1.3.72"
    kotlin("plugin.spring") version "1.3.72"
}

group = "ourGroup"
version = "0.0.1"
java.sourceCompatibility = JavaVersion.VERSION_1_8

repositories {
    mavenCentral()
}

extra["springCloudVersion"] = "Hoxton.RELEASE"

dependencyManagement {
    imports {
        mavenBom("org.springframework.cloud:spring-cloud-dependencies:${property("springCloudVersion")}")
    }
}

dependencies {
    implementation("org.springframework.cloud:spring-cloud-starter-stream-kafka")
    implementation("org.springframework.boot:spring-boot-starter-actuator")
    implementation("io.micrometer:micrometer-registry-prometheus")
    implementation("org.springframework.boot:spring-boot-starter-webflux")
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
    testImplementation("org.springframework.boot:spring-boot-starter-test") {
        exclude(group = "org.junit.vintage", module = "junit-vintage-engine")
    }
    testImplementation("io.projectreactor:reactor-test")
    testImplementation("org.springframework.security:spring-security-test")
}

tasks.withType<Test> {
    useJUnitPlatform()
}

tasks.withType<KotlinCompile> {
    kotlinOptions {
        freeCompilerArgs = listOf("-Xjsr305=strict")
        jvmTarget = "1.8"
    }
}

现在，如果我们只是用如下所示的新的Spring Boot版本更新build.gradle.kts，我们的kafka度量标准就会消失：

    id("org.springframework.boot") version "2.3.0.RELEASE"

提前感谢您的帮助！如果你需要任何其他细节让我知道！

它适用于普通的spring-kafka消费者

@SpringBootApplication
public class So62292889Application {

    public static void main(String[] args) {
        SpringApplication.run(So62292889Application.class, args);
    }

    @KafkaListener(id = "so62292889", topics = "so62292889")
    public void listen(String in) {
        System.out.println(in);
    }

    @Bean
    public NewTopic topic() {
        return TopicBuilder.name("so62292889").partitions(1).replicas(1).build();
    }

    @Bean
    public ApplicationRunner runner(MeterRegistry registry) {
        return args -> {
            registry.getMeters().forEach(meter -> System.out.println(meter.getId()));
        };
    }

}

MeterId{name='kafka.consumer.outgoing.byte.total'...

我看你用的是春云流。问题是这个项目创建了自己的生产者/消费者工厂，并且没有添加千分尺监听器。

我打开了一个针对活页夹的问题。
