自动连线的带注释的Bean在侦听器类中为null

Question

I get null logservice in after method.

I used @Component, @ComponentScan, @Service and @Configuration, but none worked.

Here is my Listener class

@Component
public class LogOrder {

   private static LogService logService;

   @Autowired
   public void setLogService(LogService logService) {
       LogOrder.logService = logService;
   }   

   @PostUpdate
   private void after(Order order) {           
       logService.log("Logged");
   }

}

Here is my Entity class

@EntityListeners(LogOrder.class)
@Entity
public class Order{
}

Here is LogService interface and its implementation

public interface LogService {
    void send("");
}

@Service(value = "logService")
public class LogServiceImpl implements LogService {

    private final SomeOtherService someOtherService;

    @Autowired
    public LogServiceImpl(SomeOtherService someOtherService) {
        this.someOtherService = someOtherService;
    }

    public void send(String someText) {
        SomeTemplate someTemplate = someOtherService.someTemplate();
        someTemplate.convertAndSend(someText);
    }
}

What can I do to get LogService not null.

Answer 1

You are trying to autowire a static field.

   private static LogService logService;

Remove static from the attribute.
