Maven 的 AspectJ 模块依赖 - 如何使用依赖模块的类型间声明方法
[英]AspectJ module dependency with Maven - How get working the Inter-type declarations methods of a dependency module
问题描述
这是我的情况：
我有一个由两个 jar 模块组成的 maven 项目my-project-aj-dependency ：
-
my-project-aj-dependencyJarWithAJ（我有一个Inter-type 声明，请参阅下面AppWithAj_Ahah.aj方面的ahah()方法） -
my-project-aj-dependencyJarWithoutAJ
我的问题是我想使用在第二个模块中的第一个模块的方面中定义的一些声明方法，但可能我错过了一些东西。
我的poms配置如下：

AppWithAj.java在哪里：
package org.my.project.aj.dependencyJarWithAJ;
public class AppWithAj {
public static void main( String[] args ){
System.out.println( "Hello World!" );
}
}
而AppWithAj_Ahah.aj是：
package org.my.project.aj.dependencyJarWithAJ;
public aspect AppWithAj_Ahah {
public String AppWithAj.ahah(){
return "Ahahahah!";
}
}
最后App.java是：
package org.my.project.aj.dependencyJarWithoutAJ;
import org.my.project.aj.dependencyJarWithAJ.AppWithAj;
public class App {
public static void main( String[] args ) {
System.out.println( "Hello World! " + new AppWithAj().ahah());
}
}

您的解决方案太复杂了：
- AspectJ (AJ) 模块需要 AJ Maven 插件和对aspectjrt的依赖。 到目前为止，很好。
- 但是声明的方面只影响它自己模块中的一个类，通过 ITD 扩展它。 所以没有必要在纯 Java 模块上使用 AJ 编译器，它只从 AJ 模块调用一个方法。 被调用的方法是由 ITD 创建的无关紧要，对于其他模块来说，它看起来就像普通的 Java。
- 因此，所有非 AJ 模块需要的是对 AJ 模块的正常依赖，因为它使用其类之一。 AJ 运行时依赖项是可传递的，应该自动使用。

带有 AspectJ 的模块：

请注意：我添加了 Exec Maven 插件只是为了演示目的，因此您可以执行以下操作：
mvn clean install
mvn -pl my-project-aj-dependencyJarWithoutAJ exec:java
然后你应该在控制台上看到这样的东西：
(...)
[INFO] --- exec-maven-plugin:1.4.0:java (default-cli) @ my-project-aj-dependencyJarWithoutAJ ---
Hello World! Ahahahah!
从根和普通 Java POM 中删除 Exec Maven 以获得更短的 POM。

我在这里展示了它的工作原理： AspectJ module dependency with Maven
编辑：似乎如果 nonAj 项目没有 AspectJ 性质，它会在 .aj 定义的方法附近警告您（尽管如果您简单地启动它就可以正常工作，对于 eclipse 这不是错误，顺便说一句，这不允许您使用自动完成广告填充代码以减少...）。 这是快照：
