spring的cglib代理

有接口的默认是JDK的动态代理，没有接口的是cglib代理

没有接口spring自动应用cglib

package org.example;JDK

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class Hello {
    
    
    @Value("yasuo")
    private String name;

    public String sayHello(String name){
    
    
        System.out.println(name+":pasaki");
        return name;
    }

}

package org.example;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.*;
import org.springframework.stereotype.Component;

import java.util.Date;

@Component
@Aspect
public class MyAspect {
    
    

    @Pointcut("execution(public String org.example.Hello.sayHello(String))\"")
    public void cut(){
    
    }

    @After(value = "cut()")
    public void after(){
    
    
        System.out.println("最终通知");

    }

    @Before(value = "cut()")
    public void before(){
    
    
        System.out.println("前置通知");

    }
}

    @Test
    public void shouldAnswerWithTrue()
    {
    
    
        //1、指定spring配置文件的名称
        String config="spring_total" + ".xml";
        //2、创建表示spring容器的对象，ApplicationContext
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(config);
        //3、通过容器获取对象
        Hello hello =(Hello)context.getBean("hello");
        String  result=hello.sayHello("yasuo");
        System.out.println(result);
    }

有接口应用cglib代理

在spring 配置文件中

<aop:aspectj-autoproxy proxy-target-class="true"/>
