AspectJ 配置/设置 - 切入点未触发答案

【问题标题】：AspectJ configuration / setup - pointcuts not firingAspectJ 配置/设置 - 切入点未触发
【发布时间】：2022-11-01 16:57:23
【问题描述】：

我正在尝试让我的第一个 AspectJ 方面运行。按照我能找到的文档，安装程序对我来说看起来不错。例如

开发者网站：https://github.com/kriegaex/org.aspectj
设置说明：https://github.com/eclipse/org.aspectj/blob/master/docs/developer/IDE.md
连接点示例：https://www.eclipse.org/aspectj/doc/released/progguide/language-joinPoints.html

但是，无论我今天尝试了哪些选项，都不会触发任何方面。

我相信切入点正确指向我的方法调用，因为我在更改切入点时收到了关于未使用切入点的错误。（现在没有发生 - 不知道我做了什么:-()）

那么是设置的问题吗？切入点？你如何去调试这种情况？我在文档中遗漏了什么吗？

【问题讨论】：

如果有一个带有工作 AspectJ 示例的公共 Intellij 项目，那将是一个很大的帮助
您不需要 IntelliJ 项目，因为如果您激活 IntelliJ 的 AspectJ 支持，它会在自动导入正确的 Maven 项目时自动正确配置项目。

标签： java aspectj

【解决方案1】：

您是否尝试过不使用 Lombok 以避免this problem？尝试在您的测试类中手动执行 Lombok 注释所做的操作。

在我们确定这可以解决问题后，我们可以开始查看possible workarounds。如果这确实是您的第一个 AspectJ 问题，那么您不应该从 AspectJ + Lombok 之类的困难组合开始。

此外，如果您的 @Data 类是不可变的，那么您可能根本不需要 Lombok，并且可以为此使用最新的 Java 版本和本机 Java 记录。
