                  @RequestParam：  ·取querystring当中的参数
                  @PathVariable：     取 在@RequestMapping中定义的占位符中的参数（/test/{id}）
                  @RequestBody：   取request 这个消息体 （可以组装json对象）

在不使用注解的情况下，默认有一些对象可以自动注入如：

                  HttpServletRequest
                  HttpServletResponse
                  MultipartFile
                  MultipartRequest

除此之外不使用注解的情况下，也可以接受前台传入的querystring中的参数

1、JSON化参数：

前台js发送请求：

$.ajax({   type:"POST",   url:"/item/getRequestArrayData",   dataType:"json",           contentType:"application/json",                 data:JSON.stringify(itemArray),   success:function(data){   console.log(data);                         }   });  

JAVA后台接收：

   @RequestMapping(value="/getRequestArrayData")  @ResponseBody  public Map<String,Object> getRequestArrayData(@RequestBody List<Item> itemList){  for(Item item:itemList){  //打印接收到的数据  System.out.println(item.getId()+"----"+item.getItem_name());  }  return null;  }  

2、使用HttpServletRequest 接收参数数组

js发送请求：

                var imageUrlArr = [];$.each($("input[name=imageUrlFlag]"),function(index,obj){imageUrlArr.push($(obj).attr('id'));});data.field.imageUrl = imageUrlArr;$.post(URL,data.field, function(result) {if(result.status ==0){Msg.ok(result.msg);//关闭页面if(flagAdd=='add'){tabUtil.tabDelete('posterThemeTableTab',-1);}else{tabUtil.tabDelete('posterThemeTableTab',data.field.themeId);}//页面切换tabUtil.tabChange('posterThemeTableTab',0);//刷新页面table.reload('posterThemeTab', {url: baseUrl+'/postertheme/listPosterThemeByPage',page: {curr: 1 //重新从第 1 页开始}});}else{Msg.fail(result.msg);}

后台接收：

@RequestMapping(value="addPosterTheme",method=RequestMethod.POST)@ResponseBodypublic ResponseVo addPosterTheme(ScreenPosterThemeDto screenPosterThemeDto,HttpServletRequest request) {ResponseVo vo = new ResponseVo();String [] imageUrls  =request.getParameterValues("imageUrl[]");//查看新增的主题是否存在//新增try {ScreenPosterThemeDto addPosterTheme = posterThemeService.addPosterTheme(screenPosterThemeDto);List<ScreenPosterDto> list = new ArrayList<>();for (String  imageUrl: imageUrls) {ScreenPosterDto screenPosterDto = new ScreenPosterDto();screenPosterDto.setThemeId(addPosterTheme.getThemeId());screenPosterDto.setImageUrl(PropertiesConstant.FDFS_DOMAIN+"/"+imageUrl);list.add(screenPosterDto);}Integer res = posterService.addPosters(list);if(res>0){vo.setStatus(ResponseEnum.SUCCESS.getStatus());vo.setMsg("添加成功");}} catch (Exception e) {e.printStackTrace();vo.setStatus(ResponseEnum.FAIL.getStatus());vo.setMsg("添加失败");}return vo;}
