Exposing a custom Spring Boot Actuator endpoint

The @ReadOperation annotation will expose the Getter for the custom endpoint and the @WriteOperation will expose the Setter for the custom endpoint. The endpoint will be mapped under the http://<host>:<port>/actuator/custom URL (the default host is localhost, and the default port is 8080 unless configured otherwise) and also exposed as a JMX Management bean:

@Component
@Endpoint(id = "custom")
public class CustomEndpoint {

    private final static Logger LOGGER = 
     LoggerFactory.getLogger(CustomEndpoint.class);

    @ReadOperation
    public String get() {
        return "Custom Endpoint";
    }

    @WriteOperation
    public void set(String message) {
        LOGGER.info("Custom Endpoint Message {}", message);
    }
}
