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.
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：
@Component
public class ServiceBHealthIndicator implements HealthIndicator {
private final String message_key = "Service B";
@Override
public Health health() {
if (!isRunningServiceB()) {
return Health.down().withDetail(message_key, "Not Available").build();
}
return Health.up().withDetail(message_key, "Available").build();
}
private Boolean isRunningServiceB() {
Boolean isRunning = true;
// 在这里添加您的逻辑
return isRunning;
}
}
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：
{
"status":"DOWN",
"details":{
"serviceB":{
"status":"UP",
"details":{
"Service B":"Available"
}
},
"serviceC":{
"status":"DOWN",
"details":{
"Service C":"Not Available"
}
}
}
}
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):
@Component
public class ServiceBHealthIndicator implements HealthIndicator {
private final String message_key = "Service B";
@Override
public Health health() {
if (!isRunningServiceB()) {
return Health.down().withDetail(message_key, "Not Available").build();
}
return Health.up().withDetail(message_key, "Available").build();
}
private Boolean isRunningServiceB() {
Boolean isRunning = true;
// Your logic here
return isRunning;
}
}
If you combine it with other health indicators like the one before, you can get a health endpoint response in a way like this:
{
"status":"DOWN",
"details":{
"serviceB":{
"status":"UP",
"details":{
"Service B":"Available"
}
},
"serviceC":{
"status":"DOWN",
"details":{
"Service C":"Not Available"
}
}
}
}
You can find more information about custom health checks and endpoints in the spring boot documentation.
