5.3.Spring AOP基于XML方式实现(了解)

• • test文件顶部配置
  • @SpringJUnitConfig(locations = "spring.xml")
  • TODO: xml配置
  • <?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.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop https://www.springframework.org/schema/aop/spring-aop.xsd">
