在网上复制了一下SpringMVC.xml文件，报了个的

Referenced file contains errors (http://www.springframework.org/schema/context/spring-context-3.1.xsd).  For more information, right click on the message in the Problems View and select "Show Details..." spring-mybatis.xml /test_mass/src/main/resources line 1 XML Problem

错误，在网上找了半天,又看了以前的项目 。最后把SpringMVC头部的

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
     http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
     version="3.0">

改成了
