Tomcat中的Web应用程序部署状态

Question

I have java web application (.war) and deployed into application server (tomcat or any app server). I need to write a REST API which returns health check of that application or status of deployment of that application in server.

So my requirement something like,

http://<host>:<port>/myapp/healthcheck

response : {"status":"UP"}

How I can implement this feature. I have tried JavaMelody but I have not seen status or health check API in JavaMelody which return application deployment status.

Answer 1

You might like wildfly's health check . That allows you to create JAXRS endpoints annotated with @Health and returning status UP or DOWN depending on the app state.

@GET
@Path("/health")
@Health
public HealthStatus checkHealth() {
   return isMyAppOK() ? HealthStatus.up() : HealthStatus.down();
}

Other option can be spring boot actuator which exposes /health endpoint to your spring boot application.
