spring报错:通配符的匹配很全面, 但无法找到元素 'context:annotation-config' 的声明

最近在自学Java Spring，在使用注解装配的时候，遇到了如下报错:
通配符的匹配很全面, 但无法找到元素 ‘context:annotation-config’ 的声明, 具体报错信息如下:

Exception in thread "main" org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 68 in XML document from class path resource [Beans.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 68; columnNumber: 32; cvc-complex-type.2.4.c: 通配符的匹配很全面, 但无法找到元素 'context:annotation-config' 的声明。    at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:399)    at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:336)    at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:304)    at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:181)    at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:217)    at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:188)    at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:252)    at org.springframework.context.support.AbstractXmlApplicationContext.loadBeanDefinitions(AbstractXmlApplicationContext.java:127)    at org.springframework.context.support.AbstractXmlApplicationContext.loadBeanDefinitions(AbstractXmlApplicationContext.java:93)    at org.springframework.context.support.AbstractRefreshableApplicationContext.refreshBeanFactory(AbstractRefreshableApplicationContext.java:129)    at org.springframework.context.support.AbstractApplicationContext.obtainFreshBeanFactory(AbstractApplicationContext.java:614)    at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:515)    at org.springframework.context.support.ClassPathXmlApplicationContext.<init>(ClassPathXmlApplicationContext.java:139)    at org.springframework.context.support.ClassPathXmlApplicationContext.<init>(ClassPathXmlApplicationContext.java:83)    at MainApp.main(MainApp.java:13)

经过搜索，发现是由于虽然定义了context的namespace但是没有指定context对应的xsd文件的位置。即需要在schemaLocation当中添加context对应的位置。

<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.xsd">

即上文档中的

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