vaadin + spring boot : 요청시 오류 페이지로 전달할 수 없음

Question

단일보기 응용 프로그램 vaadin 7.7.7, spring-boot 1.5 사용자로부터 uri fragment https :/tld/#! category-name-1을 확인하고 범주 쇼 항목을 존재하고 난 오류가 발생했습니다 (임베디드 바람둥이와) 업데이트 스프링 부팅 1.5 angel이라는 7.7.7 후하지 않을 경우

VaadinService.getCurrentResponse().sendError(404, "page not found!"); 

하지만 :

Cannot forward to error page for request [/vaadinServlet/UIDL/] as the response has already been committed. As a result, the response may have the wrong status code. If your application is running on WebSphere Application Server you may be able to resolve this problem by setting com.ibm.ws.webcontainer.invokeFlushAfterService to false 

어떻게 내가 만약 angel에서 HTTP 오류 페이지를 보낼 수 있습니다 사용자에게? ErrorPageCutomizer.java

@Component 
public class ErrorPageCutomizer implements EmbeddedServletContainerCustomizer { 
    @Override 
    public void customize(ConfigurableEmbeddedServletContainer container) { 
     container.addErrorPages(new ErrorPage(HttpStatus.NOT_FOUND, "/error/404")); 
     container.addErrorPages(new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR, "/error/500")); 
    } 
} 

RestController.java

import org.springframework.boot.autoconfigure.web.ErrorController; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RestController; 

@RestController 
public class ErrorHandlingController implements ErrorController { 

    private static final String PATH = "/error"; 

    @RequestMapping(value = PATH + "/404") 
    public String error404() { 
     return "<div style='font-weight:bold; margin-top:200px; text-align:center; font-size:160%;'>Page not found...<br><a href=\"https://tld\">to home</a></div>"; 
    } 

    @RequestMapping(value = PATH + "/500") 
    public String error500() { 
     return "<div style='font-weight:bold; margin-top:200px; text-align:center; font-size:160%;'>500 Internal server error...</div>"; 
    } 

    @Override 
    public String getErrorPath() { 
     return PATH; 
    } 
}

Soliution했다 :

@Configuration 
public class AppInitializer implements WebApplicationInitializer { 

    @Bean 
    public ErrorPageFilter errorPageFilter() { 
     return new ErrorPageFilter(); 
    } 

    @Bean 
    public FilterRegistrationBean disableSpringBootErrorFilter(ErrorPageFilter filter) { 
     FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(); 
     filterRegistrationBean.setFilter(filter); 
     filterRegistrationBean.setEnabled(false); 
     return filterRegistrationBean; 
    } 
}

당신이 SystemMessagesProvider을 시도했습니다. 그 프로 바이더에서 당신은 다양한 오류에 대한 errorUrl을 정의 할 수 있습니다 :

public class YourServlet extends VaadinServlet 
{ 
    @Override 
    protected void servletInitialized() throws ServletException 
    { 
     super.servletInitialized(); 

     getService().setSystemMessagesProvider(new SystemMessagesProvider() 
     { 
      @Override 
      public SystemMessages getSystemMessages(SystemMessagesInfo systemMessagesInfo) 
      { 
       final CustomizedSystemMessages c = new CustomizedSystemMessages(); 
       final String errorUrl = "<url to errorpage>"; 
       c.setSessionExpiredURL(errorUrl); 
       c.setSessionExpiredNotificationEnabled(false); 

       c.setAuthenticationErrorURL(errorUrl); 
       c.setAuthenticationErrorNotificationEnabled(false); 

       c.setCommunicationErrorURL(errorUrl); 
       c.setCommunicationErrorNotificationEnabled(false); 

       c.setCookiesDisabledURL(errorUrl); 
       c.setCookiesDisabledNotificationEnabled(false); 

       c.setInternalErrorURL(errorUrl); 
       c.setInternalErrorNotificationEnabled(false); 

       c.setSessionExpiredURL(errorUrl); 
       c.setSessionExpiredNotificationEnabled(false); 
       return c; 
      } 
     }); 
    }
