java - 注入(inject)EntityListener

Question

当我尝试启动服务器 JBoss 7.0 时遇到问题，因为抛出错误。当将entityListiner放在Entity上时会发生这种情况。

是否可以注入(inject)实体监听器？

实体:

@Entity
@EntityListeners({Listener.class})
public class DetalleBeca implements Serializable {
...
..
}

监听者:

public class Listener {
@Inject
private LogFacade logFacade;    

@PostRemove
public void metodoRemover(DetalleBeca detalle) throws LogException {
        logfacade.reg(detalle)
        System.out.println(detalle);
}

你是对的。这是EAP 7.0 中的一个错误。这是门票:JBEAP-5371 , WFLY-2387
