问题

使用spring的切面编程时遇到一个错误，错误原因如下

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.aop.aspectj.AspectJPointcutAdvisor#0': Cannot create inner bean '(inner bean)#53f65459' of type [org.springframework.aop.aspectj.AspectJMethodBeforeAdvice] while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#53f65459': Resolution of declared constructors on bean Class [org.springframework.aop.aspectj.AspectJMethodBeforeAdvice] from ClassLoader [sun.misc.Launcher$AppClassLoader@18b4aac2] failed; nested exception is java.lang.NoClassDefFoundError: org/aspectj/lang/JoinPoint

最重要的一句话就是
Error creating bean with name ‘org.springframework.aop.aspectj.AspectJPointcutAdvisor#0’: Cannot create inner bean ‘(inner bean)#53f65459’ of type [org.springframework.aop.aspectj.AspectJMethodBeforeAdvice] while setting constructor argument;

看这个说明，不能创建xxx，应该就是少导入jar包了

解决

解决方法很简单，导入对应的jar包就行，如下

        <!-- https://mvnrepository.com/artifact/org.aspectj/aspectjweaver -->
        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjweaver</artifactId>
            <version>1.9.19</version>
            <scope>runtime</scope>
        </dependency>

导入之后成功解决问题
