我收到错误:
javax.ejb.EJBException:javax.ejb.EJBException: javax.ejb.CreateException:无法创建无状态EJB
在我的应用中,我有以下代码:
@Path("/nodos")
@Stateless
public class NodosRestController extends NodosControllerRestController{
@Context
protected HttpServletRequest request;
@Inject
Log log;
@EJB(beanName = "NodoManager")
private NodoManager nm;
@EJB(name="TareaDescargaEventos")
private TareaDescargaEventos tde;
@EJB(beanName="TareaTransferenciaHuellas")
private TareaTransferenciaHuellas tareaTransferenciaHuellas;
@Resource
UserTransaction transaccion;
public NodosRestController() {
}
@GET
@GsonDevRootName("nodo")
@Produces(MediaType.APPLICATION_JSON)
public List<Nodo> getAllNodos() throws Throwable {
return nm.findAllNodos();
}
@PUT
@GsonDevRootName("nodo")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Nodo updateNodo(Nodo nodo) throws Throwable {
transaccion.begin();
nodo = nm.updateNodo(nodo);
transaccion.commit();
return nodo;
}
}
当我不使用&#39;延伸&#39;程序工作,但当我使用它时程序失败
NodosControllerRestController
课在这里:
public abstract class NodosControllerRestController {
@Context
protected UriInfo context;
@Context
protected HttpServletRequest request;
@Context
protected HttpServletResponse response;
//more code
}

您所显示的代码可能会出错,可能有多种原因。原因可能是在Glassfish注入字段或方法依赖期间遇到冲突异常。只需检查NodosControllerRestController
是否存在任何不一致之处。进一步分析您的异常堆栈跟踪也会有所帮助。
