使用setting配置web.xml

<error-page>
    <error-code>500</error-code>
    <location>/error/500</location>
</error-page>

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

创建新控制器

   /**
     * Error Controller. handles the calls for 404, 500 and 401 HTTP Status codes.
     */
    @Controller
    @RequestMapping(value = ErrorController.ERROR_URL, produces = MediaType.APPLICATION_XHTML_XML_VALUE)
    public class ErrorController {


        /**
         * The constant ERROR_URL.
         */
        public static final String ERROR_URL = "/error";


        /**
         * The constant TILE_ERROR.
         */
        public static final String TILE_ERROR = "error.page";


        /**
         * Page Not Found.
         *
         * @return Home Page
         */
        @RequestMapping(value = "/404", produces = MediaType.APPLICATION_XHTML_XML_VALUE)
        public ModelAndView notFound() {

            ModelAndView model = new ModelAndView(TILE_ERROR);
            model.addObject("message", "The page you requested could not be found. This location may not be current.");

            return model;
        }

        /**
         * Error page.
         *
         * @return the model and view
         */
        @RequestMapping(value = "/500", produces = MediaType.APPLICATION_XHTML_XML_VALUE)
        public ModelAndView errorPage() {
            ModelAndView model = new ModelAndView(TILE_ERROR);
            model.addObject("message", "The page you requested could not be found. This location may not be current, due to the recent site redesign.");

            return model;
        }
}

重写你的方法签名，使它接受HttpServletResponse作为参数，这样你就可以对它调用setStatus(int)。

http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-ann-requestmapping-arguments

从Spring 3.0开始，你还可以抛出一个用@ResponseStatus注释声明的Exception:

@ResponseStatus(value = HttpStatus.NOT_FOUND)
public class ResourceNotFoundException extends RuntimeException {
    ...
}

@Controller
public class SomeController {
    @RequestMapping.....
    public void handleCall() {
        if (isFound()) {
            // whatever
        }
        else {
            throw new ResourceNotFoundException(); 
        }
    }
}

如果你想从控制器返回404状态，你只需要这样做

@RequestMapping(value = "/something", method = RequestMethod.POST)
@ResponseBody
public HttpStatus doSomething(@RequestBody String employeeId) {
    try {
        return HttpStatus.OK;
    } 
    catch (Exception ex) { 
         return HttpStatus.NOT_FOUND;
    }
}

通过这样做，当您想从控制器返回404时，您将收到一个404错误。

我想提一下，Spring默认提供了404异常(不仅是)。有关详细信息，请参阅Spring文档。所以如果你不需要自己的异常，你可以简单地这样做:

 @RequestMapping(value = "/**", method = RequestMethod.GET)
 public ModelAndView show() throws NoSuchRequestHandlingMethodException {
    if(something == null)
         throw new NoSuchRequestHandlingMethodException("show", YourClass.class);

    ...

  }

因为做同一件事至少有十种方法总是好的:

import org.springframework.http.HttpStatus;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class Something {
    @RequestMapping("/path")
    public ModelAndView somethingPath() {
        return new ModelAndView("/", HttpStatus.NOT_FOUND);
    }
}
