spring配置为什么使用<aop:config>报错

<?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:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
<aop:config> //在该标签前面提示红色的圈，
<aop:pointcut id="lovo"
expression="execution(* com.lovo.cq.dao.*.*(..))" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="lovo" />
</aop:config>

Answer 1

你在applicationContext.xml 的 <beans>标签中引入aop如：xmlns:aop="http://www.springframework.org/schema/aop"
<?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:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">

所谓AOP,就是面向切面编程，当一个程序很复杂时，用面向切面的思想可以简化编程，一般做权限管理时，使用这样的思想，
