@RequestMapping("list.do")
        @ResponseBody
        public ServerResponse<PageInfo> list(@RequestParam(value = "keyword",required = false)String keyword,
                                             @RequestParam(value = "categoryId",required = false)Integer categoryId,
                                             @RequestParam(value = "pageNum",defaultValue = "1") int pageNum,
                                             @RequestParam(value = "pageSize",defaultValue = "10") int pageSize,
                                             @RequestParam(value = "orderBy",defaultValue = "") String orderBy){
            return iProductService.getProductByKeywordCategory(keyword,categoryId,pageNum,pageSize,orderBy);
        }
    
    
        //http://www.happymmall.com/product/手机/100012/1/10/price_asc
        @RequestMapping(value = "/{keyword}/{categoryId}/{pageNum}/{pageSize}/{orderBy}",method = RequestMethod.GET)
        @ResponseBody
        public ServerResponse<PageInfo> listRESTful(@PathVariable(value = "keyword")String keyword,
                                             @PathVariable(value = "categoryId")Integer categoryId,
                                             @PathVariable(value = "pageNum") Integer pageNum,
                                             @PathVariable(value = "pageSize") Integer pageSize,
                                             @PathVariable(value = "orderBy") String orderBy){
            if(pageNum == null){
                pageNum = 1;
            }
            if(pageSize == null){
                pageSize = 10;
            }
            if(StringUtils.isBlank(orderBy)){
                orderBy = "price_asc";
            }
    
            return iProductService.getProductByKeywordCategory(keyword,categoryId,pageNum,pageSize,orderBy);
        }

如果有路径变量可能存在是空的情况，例如上面的

keyword 和categoryId，可能存在为空的情况，那么

//    http://www.happymmall.com/product/100012/1/10/price_asc
        @RequestMapping(value = "/{categoryId}/{pageNum}/{pageSize}/{orderBy}",method = RequestMethod.GET)
    	
    	@RequestMapping(value = "/{keyword}/{pageNum}/{pageSize}/{orderBy}",method = RequestMethod.GET)

这两种路径是不合适的，会产生歧义。

应该用下面的形式，添加关键字（自定义占位），来区分路径：

//http://www.happymmall.com/product/keyword/手机/1/10/price_asc
        @RequestMapping(value = "/keyword/{keyword}/{pageNum}/{pageSize}/{orderBy}",method = RequestMethod.GET)
    	
    	    //http://www.happymmall.com/product/category/100012/1/10/price_asc
        @RequestMapping(value = "/category/{categoryId}/{pageNum}/{pageSize}/{orderBy}",method = RequestMethod.GET)
