使用spring spring MVC mybits 框架。前台用ajax获取表单内容，通过json传到controller，调用service 插到数据库，为什么没有值，数据库里插进去的是key，我检查了好几次，求大神解答
简化下代码，既然使用框架了就利用好框架。还有前端的一下校验可以交给jquery的validator，为了安全后端应该加一些数据的校验

添加一个括号，我也遇到过这样的坑
你写的真复杂，
springMvc前台可以封装 实体的属性 后台自动映射到该实体对应的属性中，
只要你把这个属性的name属性给对就行 不存在这么多的代码问题 也没人看的
在各个层次中断了看json数组的值，确定在哪个层次出的问题；
已自行解决，在前台页面中，key与value写反了，后台代码无任何问题
