spring mvc 用map的形式接收form表单的参数：

 

只要在@controller中有@RequestParam Map<String, Object> regUser；这个map会自动在jsp提交的时候，将name作为map的key,对应的值作为map 的value，

这种适用注册等字段复杂，但是重用性不高的情况（此时不是另建bo接收），另用map接收由于用单个参数接收url之后的参数对name是依靠数据库临时组合出来的form，

中的域值可以都接到，详见后续的不同name的多图片上传，就连url后面的参数“=”也可

不需要可以

                param.remove("navTabId");

param.remove("callbackType");

param.remove("menuitemId");

param.put("PROVINCE_AREA_KEY", param.get("provinceAreaKey"));//替换成数据库字段

param.put("CITY_AREA_KEY", param.get("cityAreaKey"));

param.put("COUNTY_AREA_KEY", param.get("country"));

param.remove("provinceAreaKey");

param.remove("cityAreaKey");

param.remove("country");

param.remove("button2");
