1 要执行的普通方法

package com.zxf.demo;
    
    public class Demo1 { 
        public void d1(){ 
               System.out.println("d1()方法。。。。");
        }
    }

2 定义环绕通知的相关类

package com.zxf.advice;
    
    
    import org.aspectj.lang.ProceedingJoinPoint;
    
    public class MyAdvice { 
        public void  mybeofre(){ 
            System.out.println("前置........");
        }
        public void  myafter(){ 
            System.out.println("后置........");
        }
        public void mythrow(){ 
            System.out.println("环绕异常通知");
        }
        public Object myarround(ProceedingJoinPoint pjo) throws Throwable{ 
    
            System.out.println("。。。执行环绕。。。");
            System.out.println("......环绕前置");
                Object obj=pjo.proceed();
            System.out.println("环绕后置........");
             return obj;
        }
    }

3 Spring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
            http://www.springframework.org/schema/beans/spring-beans.xsd
            http://www.springframework.org/schema/aop
            http://www.springframework.org/schema/aop/spring-aop.xsd">
    <bean id="myadvice" class="com.zxf.advice.MyAdvice"/>
        <aop:config>
             <aop:aspect ref="myadvice">
                 <aop:pointcut id="mypoint" expression="execution(* com.zxf.demo.Demo1.d1(..))"/>
                 <aop:before method="mybeofre" pointcut-ref="mypoint"/>
                 <aop:after method="myafter" pointcut-ref="mypoint"/>
                 <aop:after-throwing method="mythrow" pointcut-ref="mypoint"/>
                 <aop:around method="myarround" pointcut-ref="mypoint"/>
             </aop:aspect>
        </aop:config>
        <bean id="domo1" class="com.zxf.demo.Demo1"/>
    </beans>

4 编写测试类

package com.zxf.test;
    
    import com.zxf.demo.Demo1;
    import org.junit.Test;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    public class Test1 { 
        @Test
        public void test1(){ 
            ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml");
            Demo1 domo1 = ac.getBean("domo1", Demo1.class);
            domo1.d1();
        }
    }
