在xml中别忘记加入：<aop:aspectj-autoproxy proxy-target-class="true" />

<?xml version="1.0" encoding="UTF-8"?>
    <beans:beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

结果:

在这之前，要引入

<dependency>
    	<groupId>org.aspectj</groupId>
    	<artifactId>aspectjrt</artifactId>
    	<version>${org.aspectj-version}</version>
    </dependency>
    
    <dependency>
    	<groupId>org.javassist</groupId>
    	<artifactId>javassist</artifactId>
    	<version>3.20.0-GA</version>
    </dependency>
