完整错误报告

Description Resource Path Location Type
cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element ‘context:component-scan’. spring.xml /spring-study/src/main/resources line 17 XML Problem

方法1：把对应的XML头部换掉成下面这个即可（看方法2）

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

方法2：关闭Eclipse的xml自动校验

由于eclipse会自动校验xml，该错误是定义schema的xml没有下载好，也许是网络问题，也许只是校验卡了。

只需要做以下步骤就可消除红叉叉！！

window—>Preferences—>Validation—>diabled All即可
