打开spring.schemas文件，可以查看到对应命名空间内容，然后输入到配置文件中（这里要保证版本对应）
?
http\://www.springframework.org/schema/aop/spring-aop-2.0.xsd=org/springframework/aop/config/spring-aop-2.0.xsdhttp\://www.springframework.org/schema/aop/spring-aop-2.5.xsd=org/springframework/aop/config/spring-aop-2.5.xsdhttp\://www.springframework.org/schema/aop/spring-aop.xsd=org/springframework/aop/config/spring-aop-2.5.xsd
?
在配置文件中的xsi:schemaLocation标签的内容有顺序，例如
?
?
http://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-2.5.xsd
?
必须保证http://www.springframework.org/schema/aop
在?http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
前面，否则不会正确的解析
