如何使用弹簧靴执行器？官方步骤无效

Question

我尝试使用 spring boot 执行器来观察我的简单应用程序，期望观察我办公室中的应用程序。

我原来的端点可以工作，但执行器的端点不能使用以下命令。

执行的命令：

• gradle build
• java -jar build/libs/HelloWorld.jar
• curl http://localhost:8080/greet/hello -> “世界你好！”曾是 打印（预期）
• curl http://localhost:8080/health -> 状态 404，错误：不是 找到（意外）

虽然我编译了spring-boot-starter-actuator-1.5.6.RELEASE.jar，但似乎没有包含执行器的包。

你能告诉我出了什么问题吗？

我的环境：

• 在我的办公室开发服务器
• Cent OS 7
• Javac 1.8.0_101
• 弹簧靴 1.5.6
• Gradle 4.6

我的应用程序的结构：

HelloWorld - build.gradle
           - setting.gradle
           - lib
           - src/main/java - Application.java
                           - GreetController.java 

这是我的代码：

build.gradle

buildscript {
    repositories {
        maven { url "http://192.168.131.247:8081/nexus/content/repositories/maven2/" }
    }

    dependencies {
            classpath("org.springframework.boot:spring-boot-gradle-plugin:1.5.6.RELEASE")
    }
    dependencies {
        classpath fileTree('./lib') {
            include '**/*.jar'
        }
    }
}

apply plugin: 'java'
apply plugin: 'application'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'


sourceCompatibility = '1.8'
targetCompatibility = '1.8'

// configure project
configurations {
    provided
    //compile.exclude module: "spring-boot-starter-tomcat"
}
sourceSets {
    main.compileClasspath += configurations.provided
    test.compileClasspath += configurations.provided
    test.runtimeClasspath += configurations.provided
}

repositories {
    maven { url "http://192.168.131.247:8081/nexus/content/repositories/maven2/" }
}

dependencies {
    compile fileTree(dir: './lib', include: ['*.jar'])
    testCompile fileTree(dir: './lib', include: ['*.jar'])
}

springBoot {
    executable = true
}

settings.gradle

rootProject.name = 'HelloWorld'

我关注了苏珊的评论，但也没有用。

我做了什么：

• 创建 src/profile/application.yml
• 更新 build.gradle

application.yml

endpoints:
  enabled: true
  sensitive: false
  health:
    enabled: true
    sensitive: false
  info:
    enabled: true
    sensitive: false
  loggers:
    enabled: true
    sensitive: false

在 build.gradle 中，我添加了以下几行

......
sourceSets {
    main.resources {
        srcDirs "src/profile"
    }
    ......
}
......

Answer 1

它应该是 curl http://localhost:8080/actuator/health 除非您使用

更改执行器端点

management:
  endpoints:
    web:
      base-path: <endpoint>

在 yml 文件中也应该是这样的

endpoint
  health:
    enabled: true

不是endpoints

我遵循不同的方式来公开端点，如下所示，这也应该可以工作

management:
  endpoints:
      exposure:
        include: health,info

所以你的 application.yml 应该是这样的

endpoint:
  health:
    enabled: true
  info:
    enabled: true
  loggers:
    enabled: true

或

management:
  endpoints:
      exposure:
        include: health,info.loggers

Answer 2

在您的 application.properties 文件中添加以下内容

endpoints:
  enabled: true
  sensitive: false
  health:
    enabled: true
    sensitive: false
  info:
    enabled: true
    sensitive: false
  loggers:
    enabled: true
    sensitive: false
