spring - 了解 Maven 依赖树输出

Question

我正在尝试编译一个 Spring 应用程序，其中ApplicationConfig文件@EnableAspectJAutoProxy anotation在尝试运行项目时遇到此错误：

Failed to instantiate [org.springframework.aop.aspectj.annotation.
 AnnotationAwareAspectJAutoProxyCreator]:
 Constructor threw exception; nested exception is    
 java.lang.NoClassDefFoundError: org/aspectj/lang/annotation/Around

我不得不说，当我删除上面的注释时，项目运行成功。

在互联网上阅读后，我想可能是因为库和 jar 文件的版本不兼容。

当我运行mvn dependency:tree输出如下：

[INFO]    task-segment: [dependency:tree]

这是pom.xml文件的内容：

 <dependencies>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.11</version>
    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>

    </dependency>

    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjweaver</artifactId>

    </dependency>

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
    </dependency>

    <dependency>

        <artifactId>aspectjrt</artifactId>
        <version>1.8.9</version>
    </dependency>
</dependencies>

问题：我不明白这个输出是说一切都很好，或者我的项目中可能存在一些不兼容，如果有如何解决它们？
