AjaxGridServlet 우리는 글래스 피시 4 JDK 1.7로 업데이트 할 경우, 우리는 응용 프로그램을 배포하려고 다음과 같은 오류가 BaseJsonServlet. 이 문제는 TSource 인스턴스를 삽입하는이 파일에 있습니다.
public abstract class AjaxGridServlet<TSource extends AjaxGridSource<?,?>> extends BaseJsonServlet {
private static final long serialVersionUID = 1L;
@Inject
protected Instance<TSource> sourceInstance;
@Override
protected void process(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
TSource source= sourceInstance.get();
source.process(request, response);
response.getWriter().write(source.toJsonString());
}
}
AjaxGridServlet은 다음 어떤 도움을 크게 감상 할 수 것 webservlet
@WebServlet("/api/admin-dashboard")
public class AdminDashboard extends AjaxGridServlet<AdminDashboardSource> {
private static final long serialVersionUID = 1L;
}
에 의해 확장됩니다. 감사.
응용 프로그램을 배포하지만 서블릿이 작동하지 않는다고 바꿀 때. org.jboss.weld.exceptions.UnsatisfiedResolutionException을 반환합니다 : WELD-001308 Types에 대한 빈을 모두 확인할 수 없습니다 : [class com.co.ejb.web.AjaxGridSource]; 바인딩 : [QualifierInstance {annotationClass = interface javax.enterprise.inject.Default, values = {}, hashCode = -1237982948}] – user2340647
이는 컨텍스트에서 그러한 bean이 없다는 것을 의미합니까? – Bozho
AjaxGridSource는 그것을 확장하는 30 가지 이상의 클래스를 가진 추상 클래스입니다. 우리가 인스턴스>을 수행하면 org.jboss.weld.exceptions.AmbiguousResolutionException으로 끝납니다 : WELD-001318 ... –
