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：

复制代码

@InitBinder
public void initBinder(WebDataBinder binder) {

    binder.setAutoGrowCollectionLimit(**2048**);
}
