The prefix "p" for attribute "p:dataPattern" associated with an element type "bean" is not bound.

原因：

意思是: 前缀“p”属性“p:dataPattern。dataPattern”与某个元素类型相关“bean”却不被捆绑

 

这是因为在使用XML Schema作为配置文件的语义约束时,没有添加下面这条语句

xmlns:p="http://www.springframework.org/schema/p"

 

解决办法：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
