SpringMVC的controller方法中注解方式传List参数使用@RequestBody

在SpringMVC控制器方法中使用注解方式传List类型的参数时，要使用@RequestBody注解而不是@RequestParam注解：

     //创建文件夹
     @RequestMapping(value="api/createFolders",method=RequestMethod.POST)
     @ResponseBody
     public ClientResponse<LinkedHashMap<String, BookFsApiJson>> createFolders(
             @RequestParam("bookId") long bookId,
             @RequestParam("parentId") long parentId,
             @RequestBody List<String> paths,
             HttpServletRequest request) {
         int userId = loginService.getCurrentUserId(request);
         LinkedHashMap<String, BookFs> pathBookFsMap = mService.createFolders(bookId, userId, parentId, paths);
         LinkedHashMap<String, BookFsApiJson> pathBookFsJsonMap = new LinkedHashMap<>();
         for (Map.Entry<String, BookFs> entry : pathBookFsMap.entrySet()) {
             pathBookFsJsonMap.put(entry.getKey(), BookFsConverter.ConvertDomToJson(entry.getValue()));
         }
         return ClientResponse.success(pathBookFsJsonMap);
     }
