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,  8             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);
    }
