首先在spring配置文件中加上

xmlns:aop="http://www.springframework.org/schema/aop" http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd

 然后在配置文件中开启aop

 定义bean

package com.test;import org.springframework.stereotype.Component;@Component("SpringTest")public class SpringTest{	public void PrintHello(String name){		System.out.println("Hello," + name);	}		public void save(String name){		System.out.println("我是save()方法...");	}		public void update(String name){		System.out.println("我是update()方法...");	}		public void search(String search){		System.out.println("我是search()方法...");	}}

 然后定义切面

package com.test;import org.aspectj.lang.annotation.After;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;import org.aspectj.lang.annotation.Pointcut;import org.springframework.stereotype.Component;/** * 定义切面 * @author John * */@Aspect@Component("Aspject")public class Aspject {	//定义切点	@Pointcut("execution(* com.test.SpringTest.update(..))")	private void anyMethod(){}		//定义前置通知	@Before("anyMethod() && args(name)")	public void BeforeTongZhi(String name){		System.out.println("我是前置通知.....");	}		@After("anyMethod()")      public void after(){  	       System.out.println("最终通知");      }  }

 测试类

package com.test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class Test {	public static void main(String[] args) {		ApplicationContext cxt =  new ClassPathXmlApplicationContext("applicationContext.xml");		SpringTest test = (SpringTest) cxt.getBean("SpringTest");		test.update("zhangsan");	}}

 运行结果

我是前置通知.....我是update()方法...最终通知

 期间遇到一个错误

error at ::0 can't find referenced pointcut anyMethod

 是aspectjrt jar包的版本太低了。
