1、报错内容

在Spring的配置文件中报错：

Caused by: org.xml.sax.SAXParseException; lineNumber: 7; columnNumber: 66; cvc-complex-type.2.4.c:
通配符的匹配很全面, 但无法找到元素 ‘context:component-scan’ 的声明。

原配置文件：

<?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:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <context:component-scan base-package="com.test02.usermodule"></context:component-scan>


</beans>

2、解决

在xsi:schemaLocation这个字符串中添加context相关的解析文件 ：

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd

修改后配置文件：

<?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:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
              http://www.springframework.org/schema/context
              http://www.springframework.org/schema/context/spring-context-4.2.xsd">

    <context:component-scan base-package="com.test02.usermodule"></context:component-scan>

</beans>
