我不完全确定为什么会这样。我怀疑可能缺少依赖项，但由于我是 spring 引导的新手，所以我真的不明白错误消息的确切含义。 你们中有人知道为什么会发生此错误吗？如果是这样，您能告诉我您是如何得出这个结论的吗？ 让我知道我是否应该 post 我的 pom 文件。提前致谢

Answer 1

ProceedingJoinPoint在org.aspectj:aspectjweaver依赖项中可用，它包含在org.springframework:spring-aspects依赖项中。

要解决此问题，请在 POM 文件中包含以下依赖项 --

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