micronaut-spring和spring-boot-actuator，无法访问/actuator端点

Question

我正在尝试使用Spring功能的micronaut，但无法访问我的/actuator端点Spring Bootv2.3.0版本和Micronaut2.0.0.M3

我使用mn create-app xxx --lang groovy创建了一个基本的micronaut项目。

然后，我添加了spring依赖项和micronaut-spring以及相关的批注处理器。

我的build.gradle现在如下所示

plugins {
    id "groovy"
    id "com.github.johnrengelman.shadow" version "5.2.0"
    id "application"
    id "net.ltgt.apt" version "0.21"  //enables annotation preproccessing support
    id "net.ltgt.apt-idea" version "0.21"
    id "org.springframework.boot" version "2.3.0.RELEASE"
    id "io.spring.dependency-management" version "1.0.9.RELEASE"
}

ext['groovy.version'] = '3.0.4'

version "0.1"
group "com.softwood"

repositories {
    mavenCentral()
    maven { url "https://jcenter.bintray.com" }
}

configurations {
    // for dependencies that are needed for development only
    developmentOnly 
}

dependencies {

    //annotation processors
    annotationProcessor platform("io.micronaut:micronaut-bom:$micronautVersion")
    annotationProcessor "io.micronaut.spring:micronaut-spring-boot-annotation"
    annotationProcessor "io.micronaut.spring:micronaut-spring-web-annotation"
    testAnnotationProcessor "io.micronaut.spring:micronaut-spring-web-annotation:2.0.1"

    //latest groovy v3
    implementation group: 'org.codehaus.groovy', name: 'groovy-all', version: '3.0.4' //, ext: 'pom'

    //spring
    compileOnly "io.micronaut.spring:micronaut-spring-annotation:2.0.1"
    implementation("org.springframework.boot:spring-boot-starter-web")
    implementation("org.springframework.boot:spring-boot-starter-actuator")
    implementation group: 'io.micronaut.spring', name: 'micronaut-spring-web', version: '2.0.1'
    runtime ("io.micronaut.spring:micronaut-spring-boot:2.0.1")


    compileOnly platform("io.micronaut:micronaut-bom:$micronautVersion")
    compileOnly "io.micronaut:micronaut-inject-groovy"
    implementation platform("io.micronaut:micronaut-bom:$micronautVersion")
    implementation "io.micronaut:micronaut-runtime-groovy"
    implementation "io.micronaut:micronaut-validation"
    implementation "javax.annotation:javax.annotation-api"
    implementation "io.micronaut:micronaut-http-server-netty"
    implementation "io.micronaut:micronaut-http-client"
    runtimeOnly "ch.qos.logback:logback-classic:1.2.3"
    testCompileOnly platform("io.micronaut:micronaut-bom:$micronautVersion")
    testImplementation platform("io.micronaut:micronaut-bom:$micronautVersion")
    testImplementation("org.spockframework:spock-core:2.0-M2-groovy-3.0") {
        exclude group: "org.codehaus.groovy", module: "groovy-all"
    }
    testImplementation "io.micronaut:micronaut-inject-groovy"
    testImplementation "io.micronaut.test:micronaut-test-spock"
    testImplementation "io.micronaut.test:micronaut-test-junit5"
}

test.classpath += configurations.developmentOnly

mainClassName = "com.softwood.Application"

//added - enable incremetal compile feature - can't enable with annotation processors !
/*tasks.withType(GroovyCompile).configureEach {
    options.incremental = true
}*/

tasks.withType(GroovyCompile) {
    groovyOptions.forkOptions.jvmArgs.add('-Dgroovy.parameters=true')
}


shadowJar {
    mergeServiceFiles()
}

tasks.withType(JavaExec) {
    classpath += configurations.developmentOnly
    jvmArgs('-noverify', '-XX:TieredStopAtLevel=1', '-Dcom.sun.management.jmxremote')
}

我调整了一个HelloController，如下所示

import io.micronaut.http.annotation.Controller
import io.micronaut.http.annotation.Get
import io.micronaut.http.HttpStatus
import org.springframework.boot.actuate.endpoint.annotation.Endpoint


@Controller("/hello")
@Endpoint
class HelloController {

    @Get("/")
    String index() {
        return 'hello william'
    }
}

并将应用程序类标记为SpringbootApplication -但调用Micronaut.run()来构建MN上下文等

import io.micronaut.runtime.Micronaut
import groovy.transform.CompileStatic
import org.springframework.boot.autoconfigure.SpringBootApplication

@CompileStatic
@SpringBootApplication
class Application {
    static void main(String[] args) {
        Micronaut.run(Application)
    }
}

我尝试调整application.yml以公开所有端点，如下所示

micronaut:
  application:
    name: micronaut-std-app

management:
  endpoints:
    web:
      exposure:
        include=*:

这一切都编译得很好，也运行得很好。如果调用localhost:8080/hello，则会得到预期的字符串

如果您尝试访问执行器端点-没有生成任何内容，浏览器将显示

{"message":"Page Not Found","_links":{"self":{"href":"/actuator/health","templated":false}}}

如果你正在尝试做一个混合的micronaut和spring项目，那么你如何为你的MN预处理控制器等启用任何执行器端点？

Answer 1

如果您只需要运行状况检查端点，Micronaut会提供内置运行状况检查端点。

在build.gradle中添加休眠依赖，以添加像health这样的端点：

implementation("io.micronaut:micronaut-management")

您可以在application.yml中添加

endpoints:
    health:
        enabled: true

然后将运行状况检查url更改为"/health“
