Use Spring Boot Actuator without a Spring Boot Application [duplicate]

Answer 1

The project I'm working on uses Spring, but neither Spring-boot nor Spring-MVC. The following solution may not be as automagic as the actuator with boot, but it exposes the endpoints in a pretty succinct way.

Basically, all actuator endpoints are just beans, so you can create a new component and autowire in the endpoints however you see fit.

The only additional dependencies in my pom are spring-boot-actuator and spring-webmvc:

   
        org.springframework.boot
        spring-boot-actuator
        1.2.1.RELEASE
    
    
        org.springframework
        spring-webmvc 
        4.1.4.RELEASE
    

Then all you need to do is create a single component class (maybe register it if you need to). Make sure to annotate with @EnableAutoConfiguration:

@Component
@EnableAutoConfiguration
@Path("/actuator/")
public class ActuatorResource {

private ObjectMapper mapper = new ObjectMapper();


@Autowired 
private DumpEndpoint dumpEndpoint;

@GET
@Produces("application/json")
@Path("/dump")
@Transactional(readOnly = true)
public String getDump() throws JsonProcessingException { 
    return mapper.writeValueAsString(dumpEndpoint.invoke());
}

@Autowired
private EnvironmentEndpoint envEndpoint;

@GET
@Produces("application/json")
@Path("/environment")
@Transactional(readOnly = true)
public String getEnvironment() throws JsonProcessingException {
    return mapper.writeValueAsString(envEndpoint.invoke());
}

}
