SpringMvc 静态内部类 封装请求数据

最近写一个小电商项目的时候碰到一个整单/单件（退货）以及单件换货共用的一个接口

本来打算直接传json字符串作为参数的  

(List)JSONArray.toCollection(JSONArray.fromObject(json)

　后边发现利用框架进行简单粗暴的集合更方便

于是参数直接写成：

@RequestBody List<TClaimOnline> theList
//TClaimOnline为封装商品参数的单件商品对象

又发现对象中用来区别退货和换货的是对象的一个属性，于是提取出来应该是最好的

于是乎在架构师的指导下

写了一个静态内部类

@RestController
@RequestMapping(APIUrls.API_CUSTOMERSERVICE_URI)
public class ReturnExchangeController {

    @Autowired
    private ReturnExchangeService returnExchangeService;

    @Autowired
    private ShopStockService shopStockService;

    @Autowired
    private TokenManager tokenManager;

    public static class ItemReturn {
        private String retExchYn;
        private List<TClaimOnline> theList;

        public String getRetExchYn() {
            return retExchYn;
        }

        public void setRetExchYn(String retExchYn) {
            this.retExchYn = retExchYn;
        }

        public List<TClaimOnline> getTheList() {
            return theList;
        }

        public void setTheList(List<TClaimOnline> theList) {
            this.theList = theList;
        }
    }
......

方法及参数写成：

/**
     * 退换货申请
     * 
     * @param request
     * @param response
     * @return
     * @throws Exception
     */
    @RequestMapping(value = APIUrls.API_FCUSTOMERSERVICE_ITEM_RETURN_APPLICATION_URI, method = RequestMethod.POST)
    public ResponseEntity<?> itemReturnApplication(@RequestBody ItemReturn itemReturn, HttpServletRequest request,
            HttpServletResponse response) throws Exception {

很好的解决了提取共性封装数据的问题

在集合便利赋值的时候  还使用了点装B的  Java8新写法 ：

itemReturn.getTheList().forEach(t -> {
                t.setRetExchYn(itemReturn.getRetExchYn());
                t.setCustNo(custNo);
                t.setcCode(cCode);
            });

感觉高大上了很多
