我在我的@ExceptionHandler一个控制器上使用注释，但如果我使用除 以外Exception.class的任何异常类型，页面将返回消息
客户端发送的请求在语法上不正确。
这是我的控制器：
@Controller
@RequestMapping("/foobar")
public class TodayInHistoryController {
@Autowired(required = true)
private TodayInHistoryService service;
private static final String DATE_FMT = "yyyyMMdd";
/**
*
* @return
*/
@RequestMapping(method = RequestMethod.GET)
public HistoryContent getTodayInHistory(
@RequestParam(value = "date", required = false) Date date) {
if (date != null)
return service.getHistoryContent(date);
return service.getHistoryContent();
}
/**
* Binds URL arguments to their correct object representation.
*
* @param binder
*/
@InitBinder
public void initBinder(WebDataBinder binder) {
// Date object binder
SimpleDateFormat dateFormat = new SimpleDateFormat(DATE_FMT);
binder.registerCustomEditor(Date.class, new CustomDateEditor(
dateFormat, false));
}
/**
*
* @return
*/
// If I change the value param of the annotation to Exception.class it works fine...
@ExceptionHandler(NumberFormatException.class)
public ModelAndView handleParseException(Exception ex) {
// create and populate Map to hold error data
Map<String, String> errorData = new HashMap<String, String>();
errorData.put("errorMessage","Formatting error occurred");
errorData.put("errorDetails", "None");
// create and return ModelAndView
ModelAndView mv = new ModelAndView();
mv.addAllObjects(errorData);
return mv;
}
}
这是我的弹簧配置（相关的）
@Configuration
@Import(ServicesConfig.class)
@ImportResource({ "classpath:applicationContext-security.xml",
"classpath:dataSources.xml" })
@EnableWebMvc

ContentNegotiatingViewResolver resolver = new ContentNegotiatingViewResolver();
resolver.setIgnoreAcceptHeader(true);
resolver.setDefaultContentType(MediaType.APPLICATION_JSON);
resolver.setFavorPathExtension(true);
resolver.setOrder(1);
// setup mediaTypes
Map<String, String> mediaTypes = new HashMap<String, String>();
mediaTypes.put("json", "application/json");
mediaTypes.put("xml", "application/xml");
resolver.setMediaTypes(mediaTypes);
// setup defaultViews
List<View> defaultViews = new ArrayList<View>();
defaultViews.add(jsonView());
defaultViews.add(xmlView());
resolver.setDefaultViews(defaultViews);
return resolver;
}
@Bean
