异常java.lang.NoClassDefoundError：org/aspectj/lang/annotation/aspect

Question

我最近开始研究AspectJ并编写了一个用于日志记录的简单方面。

        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjrt</artifactId>
            <version>1.7.1</version>
        </dependency>
        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjweaver</artifactId>
            <version>1.7.1</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-aspects</artifactId>
        </dependency>

Answer 1

maven项目中类似这样的NoClassDefoundError通常来自库冲突。问题中的信息不足，您只提供了pom的一个片段，而没有显示您正在使用的spring aspects的版本。您需要运行mvn dependency：tree并验证您使用的是所有aspectj依赖项的一致版本号。

编辑：肯定存在某种库冲突，因为您在问题中提到了spring-aspects 3.2.1.Release，但堆栈跟踪包含大量对Spring3.1.1.Release库的引用。
