[FIXED] Show entries of cache via Spring Boots Actuator Endpoint /caches

Issue

I have a Spring Boot application with Actuator and Caching running. When I call

http://localhost:8080/actuator/caches/myCacheName

I only get some basic information about target, name and cacheManager.

But I want to see all entries of this particular cache.

So is it possible to customize this endpoint that it gives me more information?

Solution

you can customize current endpoints by extending them. This is an example using the @EndpointWebExtension annotation to extend the standard info actuator endpoint with more functionality.

example is taken from here: Extend actuator endpoints

Here is springs official documentation about extending endpoints: Spring extending endpoints

@Component
@EndpointWebExtension(endpoint = InfoEndpoint.class)
public class InfoWebEndpointExtension {

    private InfoEndpoint delegate;

    // standard constructor

    @ReadOperation
    public WebEndpointResponse<Map> info() {
        Map<String, Object> info = this.delegate.info();
        Integer status = getStatus(info);
        return new WebEndpointResponse<>(info, status);
    }

    private Integer getStatus(Map<String, Object> info) {
        // return 5xx if this is a snapshot
        return 200;
    }
}
