How to integrate with Spring boot actuator?

[ortizman]

I am using this starter to expose JAX-RS resources. Now I want to integrate Spring boot Actuator Simply, I insert the dependency in my build.gradle

Dependency implementation 'org.springframework.boot:spring-boot-starter-actuator'.

LOGS INFO 1386771 --- [ main] o.s.b.a.e.web.EndpointLinksResolver : Exposing 1 endpoint(s) beneath base path '/actuator'. But I can't access it.

Is there any alternative to access these endpoints without having to migrate to Jersey?

Hi @ortizman ,

I used the example in the project:

• https://github.com/resteasy/resteasy-spring-boot/tree/main/sample-app

And added actuator into pom.xml according to the doc:

• https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#actuator.enabling

Then I started the sample-app:

Then I tried to access the endpoint provided by actuator:

➤ curl http://localhost:8080/actuator

From the output I can see the actuator output:

Does this solve your problem?

As doc https://docs.spring.io/spring-boot/docs/current/reference/html/actuator.html#actuator.monitoring

Actuator is supported natively with Spring MVC, Spring WebFlux, and Jersey.

The sample project you mentioned uses Spring MVC https://github.com/resteasy/resteasy-spring-boot/blob/main/sample-app/pom.xml#L38 that's why actuator is working.

I think @ortizman is asking for a native support for Resteasy (in the same way of the above technologies)

This native support should cover the http tracing features of actuator https://docs.spring.io/spring-boot/docs/current/reference/html/actuator.html#actuator.tracing

@jbaris I created a Pull Request to verify the actuator behavior :

• https://github.com/resteasy/resteasy-spring-boot/pull/132/files

I deployed the sample into WildFly:

And I can see that webmvc is the core part that enable the actuator:

If I enable the above webmvc and then the actuator can work:

I need to check the detail implementation of spring-webmvc to see how it works to support actuator.

Just for the record: If you are using a JaxRS application like: @ApplicationPath("") (note this app runs on the root path)

This application will conflict with the spring-mvc path for Actuator. To solve this, just use:

management.server.port=8085 for open Actuator on another Tomcat instance

or:

spring.mvc.servlet.path=/actuator to run spring the mvc endpoint at another path.
