1. 创建一个TestBean

public class TestBean {private String testStr = "testStr";public String getTestStr() {return this.testStr;}public void setTestStr(String testStr) {this.testStr = testStr;}public void test() {System.out.println("test");}
}

2. 创建一个AspectJ类

import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;/*** Unit tests for {@link AspectJ}.** @author Lazy Hu*/
@Aspect
class AspectJ {@Pointcut("execution(* *.test(..))")public void test() {}@Before("test()")public void beforeTest() {System.out.println("beforeTest");}@After("test()")public void afterTest() {System.out.println("afterTest");}@Around("test()")public Object aroundTest(ProceedingJoinPoint p) {System.out.println("before1");Object o = null;try {o = p.proceed();}catch (Throwable throwable) {throwable.printStackTrace();}System.out.println("after1");return o;}
}

3. 创建配置文件

<?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"xsi:schemaLocation="http://www.springframework.org/schema/beans https://www.springframework.org/schema/beans/spring-beans-2.0.xsdhttp://www.springframework.org/schema/aop https://www.springframework.org/schema/aop/spring-aop-2.0.xsd"><!--开启支持注解的AOP--><aop:aspectj-autoproxy/><bean id="test" class="com.lazy.aop.test.TestBean"/><bean class="com.lazy.aop.test.AspectJ"/>
</beans>

4. 创建测试类

import org.springframework.context.support.ClassPathXmlApplicationContext;/*** Unit tests for {@link AopTests}.** @author Lazy Hu*/
class AopTests {public static void main(String[] args) {BeanFactory bf = new ClassPathXmlApplicationContext("aspectTest.xml");TestBean bean = (TestBean) bf.getBean("test");bean.test();}
}
