How to create more than one health check endpoints with Spring Boot Actuator - spring

Question

What I want to do
Create two (different) endpoints using Spring Boot Actuator
My environment
Spring Boot 1.4.2
spring-boot-starter-actuator embedded in Spring Boot 1.4.2
Detail
I'm creating a Web app using Spring Boot and will need to create two separated endpoints: one for just checking application health including the app's DB connection and so on (This will be realized by the default behavior of "/health") and the other for just checking if the app is ready for accepting HTTP requests (say "/httpcheck").
To implement health check feature, I guess it's the fastest way to use Spring Boot Actuator (by default, /health is mapped to health check endpoint).
I also understand we can configure this endpoint by extending AbstractHealthIndicator (so that it will include DB health check).
But as far as I could see, I could not find a way to create more than one endpoints to do different health checks.
Do you have any ideas?
Thanks in advance.

Answer 1

Thanks for your answer.
Actually, I dealt with this problem by implementing a new endpoint (/httpcheck) to simply check if its HTTP stack works well or not.
HttpCheckEndpoint.java
#Component
#ConfigurationProperties(prefix = "endpoints.httpcheck") // Specifies the prefix on application.yml
public class HttpCheckEndpoint extends AbstractMvcEndpoint {
public HttpCheckEndpoint() {
super("/httpcheck", false);
}
/**
* Check if simply the app can connect to their own HTTP stack and return 200 OK.
* <ul>
* <li>Method: GET, HEAD, POST, PUT, PATCH, DELETE, OPTIONS</li>
* <li>Endpoint: "/httpcheck"</li>
* </ul>
*/
#RequestMapping
#ResponseBody
public ResponseEntity<String> checkHttpConnecton() {
if (!isEnabled()) {
return new ResponseEntity<String>("", HttpStatus.NOT_FOUND);
} else {
return new ResponseEntity<String>("{\"status\": \"UP\"}", HttpStatus.OK);
}
}
}
application.yml
endpoints:
enabled: false # Default enabled/disabled on endpoints on Spring Boot Actuator
health: # Health check (already prepared in Spring Boot Actuator)
enabled: true
httpcheck: # Simple HTTP connection check (newly created by myself)
enabled: true
I've confirmed it worked well, although not sure if it's the best solution...

Solution
You can use Jolokia end points in your Spring-boot application and get it registered with o.s.b.a.e.jmx.EndpointMBeanExporter along with your Actuator Plugins.
<dependency>
<groupId>org.jolokia</groupId>
<artifactId>jolokia-core</artifactId>
<version>1.2.2</version>
</dependency>
Jolokia Configurations in application.properties
jolokia.config.debug=true
endpoints.jolokia.enabled=true
