原因解释：
Spring接受前台的数据超过2048出现如下异常：前台的Form 元素绑定到 后台的JaveBean对象，做的一个映射，但是这个映射的List长度不可以超过2048
溯源了下Spring的代码，找到了DataBinder，先解释下DataBinder类的作用，见链接
链接: http://docs.spring.io/spring/docs/1.2.x/api/org/springframework/validation/DataBinder.html
可以在controller 规定 长度即可；
解决方案：
@InitBinder
public void initBinder(WebDataBinder binder) {binder.setAutoGrowCollectionLimit(**2048**);
}
