java - 如何使详细主题应用于异常处理生成的错误页面？

Question

我使用了 Spring MVC 异常处理。修改 web.xml 像

<error-page>
    <error-code>404</error-code>
    <location>/error</location>
</error-page>

@Controller
class GeneralErrorHandlerController {

    @RequestMapping("error")    
    public String handelError(final HttpServletRequest request, final Model model) {
         /**
      * Process the error details received in the request
     */

     // Lets get the status code and uri from the request
     final Integer statusCode = (Integer) request.getAttribute("javax.servlet.error.status_code");      
     String requestUri = (String) request.getAttribute("javax.servlet.error.request_uri");
          if (requestUri == null) {
        requestUri = "Unknown";
      }
      // create a message to be sent back via the model object.
      final String message = MessageFormat.format("{0} returned for {1}", 
        statusCode, requestUri); 

       model.addAttribute("errorMessage", message);
        return "Common/Error/globalError";
    }
}

但详细信息主题不适用于返回 View 。所以请让我知道如何实现它。

也许你可以尝试这样的事情。我为所有 Controller 实现了一个抽象基类。这个基类有一个例程来处理 servlet 遇到的所有 http 错误。

    @ExceptionHandler()
    public ModelAndView handleException(ServletException exception, HttpServletResponse response) {
    response.setStatus(HttpServletResponse.SC_BAD_REQUEST);

    // populate your modell with data, choose errorpage etc.

    }
