重载Post请求映射

Question

我想重载一个Spring控制器的RequestMapping。控制器得到POST作为请求方法，我需要通过它不同的参数来超载它。

我怎么能做到这一点，而无需更改网址？

@RequestMapping(method = RequestMethod.POST, value = "/windparks/import/error") 
public ModelAndView handleFileUploadError(Locale locale, @AuthenticationPrincipal SpringUser authenticatedUser, List<RegulationEvent> regList, @RequestParam("regulations") MultipartFile regulations, RedirectAttributes redirectAttributes, @PathVariable String windparkId) throws IOException, WindSpeedInterpolator.TimeSeriesMismatchException, SAXException { 
    ModelAndView view = new ModelAndView("uis/windparks/parkdetail"); 

    view.addObject("failedEvents", regList); 
    view.addObject("windparkId", windparkId); 


    return view; 
} 

@RequestMapping(method = RequestMethod.POST, value = "/windparks/import/error") 
public ModelAndView handleFileUploadError(Locale locale, @AuthenticationPrincipal SpringUser authenticatedUser, RedirectAttributes redirectAttributes, @PathVariable String windparkId) throws IOException, WindSpeedInterpolator.TimeSeriesMismatchException, SAXException { 
    ModelAndView view = new ModelAndView("uis/windparks/parkdetail"); 

    view.addObject("windparkId", windparkId); 


    return view; 
} 

Answer 1

您可以使用注释@RequestParamparams选项，如：

@RequestMapping(method = RequestMethod.POST, value = "/windparks/import/error", params = {"locale", "authenticatedUser", "regList", "regulations", "windparkId"}) 
public ModelAndView handleFileUploadError(Locale locale, @AuthenticationPrincipal SpringUser authenticatedUser, List<RegulationEvent> regList, @RequestParam("regulations") MultipartFile regulations, RedirectAttributes redirectAttributes, @PathVariable String windparkId) throws IOException, WindSpeedInterpolator.TimeSeriesMismatchException, SAXException { 
    ModelAndView view = new ModelAndView("uis/windparks/parkdetail"); 

    view.addObject("failedEvents", regList); 
    view.addObject("windparkId", windparkId); 


    return view; 
} 

@RequestMapping(method = RequestMethod.POST, value = "/windparks/import/error", params = {"locale", "authenticatedUser", "windparkId"}) 
public ModelAndView handleFileUploadError(Locale locale, @AuthenticationPrincipal SpringUser authenticatedUser, RedirectAttributes redirectAttributes, @PathVariable String windparkId) throws IOException, WindSpeedInterpolator.TimeSeriesMismatchException, SAXException { 
    ModelAndView view = new ModelAndView("uis/windparks/parkdetail"); 

    view.addObject("windparkId", windparkId); 


    return view; 
} 

也许不适合你，但你可以在Spring检查params手册。
