Spring Boot Actuator 不工作並且 application.properties 在 STS 中是未知的

Question

嘗試使用Web和執行器依賴項測試Spring Initializr Starter，但執行器端點未啟用。

我期待在Spring Boot Actuator: Production-ready features 的每個文檔的日志中映射 /actuator/health

我在application.properties 中嘗試了各種屬性：

management.security.enabled=false 

management.endpoints.web.exposure.include=*

management.endpoints.web.expose=*

在 STS 中，所有三行都帶有黃色下划線，並帶有指示未知屬性的消息。

我沒有碰Spring Initializr生成的pom.xml文件：

我希望這能工作，這里是沒有執行器映射的部分日志：

卷曲測試：

{"timestamp":"2018-08-07T03:09:02.385+0000","status":404,"error":"Not Found","message":"No message available","path":"/actuator/health"}

任何機構都可以告訴我我缺少什么以及為什么 STS 無法識別這些屬性嗎？

這與“SpringBoot 2.0.1 中未提供執行器/刷新”不重復。 下面的解決方案表明這是一個 JAR 損壞問題。

Answer 1

運行后

mvn clean install 

盡管 IDE 一直在運行而不告訴我有關它們的信息（奇怪），但我還是看到了多個錯誤。

刪除罐子后：

rm /Users/xxx/.m2/repository/org/springframework/boot/spring-boot-actuator-autoconfigure/2.0.4.RELEASE/spring-boot-actuator-autoconfigure-2.0.4.RELEASE.jar
rm /Users/xxx/.m2/repository/org/springframework/boot/spring-boot-actuator/2.0.4.RELEASE/spring-boot-actuator-2.0.4.RELEASE.jar
rm /Users/xxx/.m2/repository/io/micrometer/micrometer-core/1.0.6/micrometer-core-1.0.6.jar

其次是

mvn spring-boot:run

強制重新下載。

現在我看到指示暴露端點的日志：

/actuator/health 現在產生：

Answer 2

我的情況是我必須添加我的自定義 HealthIndicator：

 @Component
 public class HealthIndicator implements ReactiveHealthIndicator {

     @Override
     public Mono<Health> health() {
       return checkDownstreamServiceHealth().onErrorResume(
          ex -> Mono.just(new Health.Builder().down(ex).build())
       );
     }

     private Mono<Health> checkDownstreamServiceHealth() {
       return Mono.just(new Health.Builder().up().build());
     }
 }

我使用彈簧靴執行器 2.2.3。 來自https://www.baeldung.com/spring-boot-actuators
