SpringMVC check server is UP or DOWN

Question

How can I check if my server is UP or DOWN in SpringMVC or just simple in JAVA? I want a simple function how receiving a URL as a parameter and return just one boolean variable TRUE or FALSE which represents a SERVER.

Answer 1

@RestController
public class HealthCheckController {
    @RequestMapping("/healthcheck")
    public Greeting greeting() {
        return "up";
    }
}

When you have to check if the server is up just send get request to /healthcheck . If it returns "up", you're OK.

If you use Spring Boot, you can take a look at actuator . It allows this functionality out of the box plus some other stuff like datasource checking and so on
