Spring AOP异常：Error creating bean with name ‘org.springframework.aop.aspectj.AspectJPointcutAdvisor#0

Posted 2022-08-11 小猪快跑22

刚开始学 Spring 的时候，我在 xml 配置文件中配置 aop 就报错了，配置如下：

<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"
       xmlns:tx="http://www.springframework.org/schema/c"
       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="userId" class="com.example.user.User">
        <property name="userName" value="pig"/>
        <property name="passWord" value="123456"/>
    </bean>
    <bean id="userDaoImpl" class="com.example.user.UserDaoImpl"/>
    <bean id="logInterceptor" class="com.example.user.LogInterceptor"/>


    <aop:config proxy-target-class="true">
        <aop:pointcut id="servicePointerCut" expression="execution(* com.example.user.UserDao.saveUser(..))"/>
        <!-- 配置切面以及通知(指向切面，比如错误日志) -->
        <aop:aspect id="logAspect" ref="logInterceptor">
            <!-- method写切面中（比如错误日志）的方法名称 -->
            <aop:before method="before" pointcut-ref="servicePointerCut"/>
            <aop:after method="after" pointcut-ref="servicePointerCut"/>
        </aop:aspect>
    </aop:config>

</beans>

报错具体日志如下：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userId' defined in class path resource [aop.xml]: BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.aop.aspectj.AspectJPointcutAdvisor#0': Cannot create inner bean '(inner bean)#704d6e83' 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)#704d6e83': Cannot resolve reference to bean 'servicePointerCut' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'servicePointerCut': Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: org/aspectj/weaver/reflect/ReflectionWorld$ReflectionWorldException

解决方法就是导入以下2个依赖，maven 依赖如下：

       <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjrt</artifactId>
            <version>1.6.9</version>
            <scope>runtime</scope>
        </dependency>

        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjweaver</artifactId>
            <version>1.9.6</version>
            <scope>runtime</scope>
        </dependency>

添加依赖后，找到项目的 pom.xml 然后右击 选择 maven，然后 reload project ，如下图：

最后我的项目就能正常运行了。
