@Startup @Singleton Java注释不起作用（TomEE 8 Web Profile + CentOS 7）

Question

Trying to deploy web application on TomEE Web Edition 8.0.0-M3 (CentOS7, JDK12) - everything works, but for some reason @Startup @Singleton annotations not working - start() and destroy() methods are not called.

package test;

import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.ejb.Singleton;
import javax.ejb.Startup;

@Startup
@Singleton
public class SessionManager {

        @PostConstruct
        public void start() {
            System.out.println("PostConstruct");
        }

        @PreDestroy
        public void destroy() {
            System.out.println("PreDestroy");
        }
    }

On Win10 it works. When starting TomEE I can see that it loads openejb:

But not on CentOS.. TomEE versions and configuration identical, strange..

Downloaded TomEE plus - now it's working as expected. So it seems like TomEE webprofile version does not support EJBs??

Answer 1

It does but it seems your EJB does not have start/destroy methods, the nested class not being an EJB you end up with an empty EJB and an unmanaged class with an ignored lifecycle.

Can you drop SessionManager class and move start/destroy in NewClass?
