今天在寫spring aop示例的時候，在spring.xml檔案中新增spring aop的schema後出現紅叉，spring配置檔案如下：

<?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:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="
http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
http://www.springframework.org/schema/context 
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/aop 
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
">

</beans>
 

提示說：cvc-elt.1: Cannot find the declaration of element 'beans'，

從網上搜了一些，有的說是因為網路原因訪問不到xsd檔案，因為訪問不到網路上的xsd檔案，我們可以訪問本地的啊，在引入的spring的包中spring-beans-3.2.2.RELEASE.jar中有spring-beans-3.0.xsd檔案，其他的xsd檔案也都能在相應的包中找到，這樣就好說了，把xsd檔案的引用全部改為本地檔案：

<?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:aop="http://www.springframework.org/schema/aop" 
xsi:schemaLocation="
http://www.springframework.org/schema/beans 
classpath:/org/springframework/beans/factory/xml/spring-beans-3.0.xsd 
http://www.springframework.org/schema/context 
classpath:/org/springframework/context/config/spring-context-3.0.xsd
http://www.springframework.org/schema/aop 
classpath:/org/springframework/aop/config/spring-aop-3.0.xsd
">
	
</beans>
 

ok紅叉消失
