在Spring Boot Actuators中，有没有一种标准方法来检查子服务的健康状态？

英文:

Is there a standard way in Spring Boot Actuators of checking the health of child services?

问题

以下是要翻译的内容：

假设我有一个依赖（调用）Spring Boot服务B的Spring Boot服务A。

A -> B

Spring Boot Actuators可以告诉我A是否正常运行。

https://A/health

我想知道的是通过调用A来检查B是否正常运行。

https://A/integratedhealth

我的问题是：在Spring Boot Actuators中，是否有标准的方法来检查子服务的健康状态？
（还是我必须构建一个自定义的执行器服务？）

英文:

Suppose I have Spring Boot service A which depends on (calls) Spring Boot service B.

  1. A -> B

Spring Boot Actuators can tell me if A is up.

https://A/health

What I want to know is if B is up, by calling A.

https://A/integratedhealth

My question is: Is there a standard way in Spring Boot Actuators of checking the health of child services?
(or do I just have to build a custom actuator service?)

Spring Boot提供了许多开箱即用的健康指标。但是，您可以通过实现HealthIndicator接口（对于响应式应用程序，使用ReactiveHealthIndicator）来添加自定义健康指标：

  1. @Component
  2. public class ServiceBHealthIndicator implements HealthIndicator {
  4.     private final String message_key = "Service B";
  6.     @Override
  7.     public Health health() {
  8.         if (!isRunningServiceB()) {
  9.             return Health.down().withDetail(message_key, "Not Available").build();
  10.         }
  11.         return Health.up().withDetail(message_key, "Available").build();
  12.     }
  14.     private Boolean isRunningServiceB() {
  15.         Boolean isRunning = true;
  16.         // 在这里添加您的逻辑
  17.         return isRunning;
  18.     }
  19. }

如果将其与之前的健康指标等组合，您可以获得类似以下方式的健康端点响应：

  1. {
  2.    "status":"DOWN",
  3.    "details":{
  4.       "serviceB":{
  5.          "status":"UP",
  6.          "details":{
  7.             "Service B":"Available"
  8.          }
  9.       },
  10.       "serviceC":{
  11.          "status":"DOWN",
  12.          "details":{
  13.             "Service C":"Not Available"
  14.          }
  15.       }
  16.    }
  17. }

您可以在Spring Boot文档中找到有关自定义健康检查和端点的更多信息。

英文:

Spring boot provides a lot of Health Indicators out of the box. However, you can add your own custom health indicator by implementing HealthIndicator interface (ReactiveHealthIndicator for reactive apps):

  1. @Component
  2. public class ServiceBHealthIndicator implements HealthIndicator {
  3.     
  4.     private final String message_key = "Service B";
  6.     @Override
  7.     public Health health() {
  8.         if (!isRunningServiceB()) {
  9.             return Health.down().withDetail(message_key, "Not Available").build();
  10.         }
  11.         return Health.up().withDetail(message_key, "Available").build();
  12.     }
  13.     private Boolean isRunningServiceB() {
  14.         Boolean isRunning = true;
  15.         // Your logic here
  16.         return isRunning;
  17.     }
  18. }

If you combine it with other health indicators like the one before, you can get a health endpoint response in a way like this:

  1. {
  2.    "status":"DOWN",
  3.    "details":{
  4.       "serviceB":{
  5.          "status":"UP",
  6.          "details":{
  7.             "Service B":"Available"
  8.          }
  9.       },
  10.       "serviceC":{
  11.          "status":"DOWN",
  12.          "details":{
  13.             "Service C":"Not Available"
  14.          }
  15.       }
  16.    }
  17. }

You can find more information about custom health checks and endpoints in the spring boot documentation.
