根据您提供的错误信息，似乎是因为在初始化Spring框架的配置时，遇到了一个名为AnnotationAwareAspectJAutoProxyCreator的类无法被加载的问题。这可能是由于Java编译器找不到这个类所需的依赖库或类路径设置不正确导致的。

要解决这个问题，请按照以下步骤操作：

1. 首先确认您的项目中已经包含了所有必要的依赖库（例如，如果使用了Spring Boot，则可能需要添加spring-boot-starter-aop和spring-boot-autoconfigure等）。确保这些依赖已经被包含到项目的pom.xml文件中。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-aop</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-autoconfigure</artifactId>
    <version>2.1.1.RELEASE</version>
</dependency>

1. 如果您正在使用Maven，确保在pom.xml文件中启用了自动构建依赖。对于Spring AOP，可以使用以下指令：

   <build>
       <plugins>
           <plugin>
               <groupId>org.springframework.boot</groupId>
               <artifactId>spring-boot-maven-plugin</artifactId>
           </plugin>
       </plugins>
   </build>
   

3. 确保在项目根目录下存在`src/main/resources/META-INF/spring.factories`文件。这是一个用于存储Spring配置的特殊文件，其中包含自定义的bean工厂、切面扫描器和配置项。
4. 重新运行Maven命令以执行构建过程，确保没有出现任何错误或警告。
5. 如果问题仍然存在，尝试清理并重新构建项目。使用`mvn clean install`命令来清除项目中的所有依赖，并重新生成项目结构。

以上步骤应该能够帮助您解决问题。如果问题依然存在，建议检查其他可能导致此问题的原因，比如是否有重复的包引用或者是否已正确安装了依赖。
