接前面的那一章节内容，在想使用spring配置自动扫描包的时候报错了

按照 http://blog.csdn.net/qq_19558705/article/details/50086977

的作者所述及进行操作的时候

      <!-- 配置自动扫描的包 -->    <context:component-scan base-package="com.spring.common.beans"/>

报错信息：

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 9 in XML document from class path resource [applicationContext.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 9; columnNumber: 69; 元素 "context:component-scan" 的前缀 "context" 未绑定。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)

发现原作者使用的spring3.x的xml命名空间；

原：

<beans xmlns="http://www.springframework.org/schema/beans"      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      xmlns:util="http://www.springframework.org/schema/util"      xmlns:p="http://www.springframework.org/schema/p"      xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd          http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd  http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context-2.5.xsd"        xmlns:context="http://www.springframework.org/schema/context">

要更改成：

<?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"xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"xmlns:task="http://www.springframework.org/schema/task" xmlns:cache="http://www.springframework.org/schema/cache"xmlns:p="http://www.springframework.org/schema/p"xsi:schemaLocation="http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc.xsdhttp://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">      <!-- 配置自动扫描的包 -->    <context:component-scan base-package="com.spring.common.beans"/>

然后跑单元测试，发现没问题了。
