1.導包

aopalliance.jar

aspectjweaver.jar

2.編寫Controller

package com.chen.web;

@Controller
@RequestMapping("/list")
public class MyController {

       @RequestMapping("test.html")
	public String test(HttpServletRequest req, HttpServletResponse res){
		return "../NewFile";
	}
}

3.建立橫切處理類

package com.chen.aspect;

public class TestHelper {
	public void printTime(){
		System.out.println("current time :"+System.currentTimeMillis());
	}
}
 

4.建立AOP配置檔案spring-aop.xml

<?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-4.2.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-4.2.xsd">
            
    
    <bean id="myController" class="com.chen.web.MyController"/>
    <bean id="timeHandler" class="com.chen.aspect.TestHelper"/>
    
    <aop:config>
        <aop:aspect id="time" ref="timeHandler">
            <aop:pointcut expression="execution(* com.chen.web.MyController.test(..))" id="addAllMethod"/>
            <aop:before method="printTime" pointcut-ref="addAllMethod"/>
            <aop:after method="printTime" pointcut-ref="addAllMethod"/>
        </aop:aspect>
    </aop:config>
</beans>
 

5.部署tomcat，並測試

execution表示式解釋

execution(* com.chen.aspect..*.*(..))
