Question

我正在研究AspectJ注释，在Spring Framework中配置AOP阅读本文： http://www.tutorialspoint.com/spring/aspectj_based_aop_appoach.htm

与本文不同，我不是在我的项目中手动添加jar，而是使用Maven。

问题是当我尝试执行MainApp类时，我得到以下错误：

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'student' defined in class path resource [Beans.xml]: Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: error at ::0 can't find referenced pointcut selectAll

我想我已经错过了一些依赖但我无法理解...

这是我的 pom.xml ：

为什么我有这个问题？我该怎么做才能解决？

解决方案（由我自己解决）：

我已从pom.xml文件中删除了这两个依赖项：

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-aop</artifactId>
        <version>3.1.1.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjtools</artifactId>
        <version>1.6.2</version>
    </dependency>

我用这个替换了它：

    <dependency>
                <groupId>org.aspectj</groupId>
                <artifactId>aspectjweaver</artifactId>
                <version>1.6.8</version>
           </dependency>

似乎工作正常： - ）

@AndreaNobili，以下是我的maven依赖。很高兴你自己解决了这个问题。

<!-- Application Context -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>${spring.framework.version}</version>
</dependency>
<!-- Spring AOP -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-aop</artifactId>
    <version>${spring.framework.version}</version>
</dependency>
<!-- to use AspectJ style AOP interception -->
<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjrt</artifactId>
    <version>1.6.11</version>
</dependency>
<dependency>
