Question

模块 1 服务器端

public interface BaseInterface{
  Customer createCustomer(Profile profile);
}

public interface InterfaceA extends BaseInterface{
}

public class ServiceProducer {  
    @EJB(lookup = "java:global/path/ClassA")
    @Produces
    private InterfaceA interfaceA;
}

@Remote(ClassA.class)
public class ClassA implements InterfaceA{
    
    BaseInterface base;

    @Inject
    public ClassA(@Named BaseInterface base){
        this.base = base;
    }
    @Override
    createCustomer implementation ...
}

public class Api{
    @Inject
    InterfaceA intA;
    
    @Override
    Customer createCustomer(arg){
        intA.createCustomer
    }
}

嗨，我在运行上述代码时收到以下错误

“ClassA”的无状态EJBLocator，视图是接口InterfaceA，关联性是Local
