问题概述

Spring AOP 报错，一直显示：Error creating bean with name 'student' defined in file 的报错。从五个方向排查：第一，aspectj 包的 scope 是不是 runtime；第二，jar 包是否导全，第三，jar 包的版本是否过低；第四，xml 配置文件；第五，切入点表达式是否正确。

排查问题

aspectj

如果你的 IDE 是 IDEA，导入 aspectj 依赖包时，其 Scope 有可能是 runtime。其实，这个问题很容易发现，因为 Scope 不是 Compiler 的话，@Aspect 这个注解就无法导包。

多少个 jar 包

要使用 Spring AOP，必须导入以下 6 个 jar 包：

spring-beans；
spring-context；
spring-aop；
spring-aspects；
aopalliance；
aspectj

jar 包版本过低

博主之前用的都是 4.3.6 版本的 jar 包，经过版本调整，索性全部设置最新版本，也就是 5.3.23 版本（截止至2022年10月25日）。以下是我运行正确的 jar 包数量和 jar 包版本：

<dependency>

  <groupId>org.springframework</groupId>

  <artifactId>spring-beans</artifactId>

  <version>5.3.23</version>

</dependency>

<dependency>

  <groupId>org.springframework</groupId>

  <artifactId>spring-context</artifactId>

  <version>5.3.23</version>

</dependency>

<dependency>

  <groupId>javax.annotation</groupId>

  <artifactId>javax.annotation-api</artifactId>

  <version>1.3.2</version>

</dependency>

<dependency>

  <groupId>org.springframework</groupId>

  <artifactId>spring-aop</artifactId>

  <version>5.3.23</version>

</dependency>

<dependency>

  <groupId>org.springframework</groupId>

  <artifactId>spring-aspects</artifactId>

  <version>5.3.23</version>

</dependency>

<dependency>

  <groupId>aopalliance</groupId>

  <artifactId>aopalliance</artifactId>

  <version>1.0</version>

</dependency>

<dependency>

  <groupId>org.aspectj</groupId>

  <artifactId>aspectjweaver</artifactId>

  <version>1.9.9.1</version>

</dependency>

配置文件是否正确

注意配置文件头标签上的配置信息，xmlns:aop、xmlns:context 等，单词拼写不要错。组件（Bean）扫描的包范围也不要写错，一定要在这个范围内，否则不能扫描：

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:context="http://www.springframework.org/schema/context"

       xmlns:aop="http://www.springframework.org/schema/aop"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xsi:schemaLocation="

       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd

       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">

  <context:component-scan base-package="com.aop"/>

  <context:annotation-config/>

  <aop:aspectj-autoproxy/>

</beans>

切入点表达式是否正确

切入点表达式是否写正确？切入点表达式的基本形式都是execution(* com.*.*())。其中，通配符*非常重要。具体的语法查网上其他的资料。
