AspectJ 模块与 Maven 的依赖关系 - 如何使用依赖模块的类型间声明方法
AspectJ module dependency with Maven - How get working the Inter-type declarations methods of a dependency module
这是我的情况:
我有一个 Maven 项目 my-project-aj-dependency
由两个 jar 模块组成:
my-project-aj-dependencyJarWithAJ
(我有一个 Inter-type declaration,请参阅下方 AppWithAj_Ahah.aj
方面的 ahah()
方法)
my-project-aj-dependencyJarWithoutAJ
我的问题是我想在第二个模块中使用在第一个模块方面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:

这里我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(尽管如果您只是启动它就可以正常工作,对于 eclipse 这不是错误,顺便说一下,这不允许您使用自动完成广告用 wanings 填充代码...)。这是快照:
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,还不错。
- 但是声明的方面只影响它自己的模块中的一个 class,通过 ITD 扩展它。因此,无需在仅调用 AJ 模块中的方法的纯 Java 模块上使用 AJ 编译器。被调用的方法是由 ITD 创建的是无关紧要的,对于另一个模块来说它看起来就像正常的 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 classes 之一。 AJ 运行时依赖是可传递的,应该自动使用。
更新:
您要的是 POM,这里有。

请注意:我添加了 Exec Maven 插件只是为了演示目的,所以你可以这样做:
mvn clean install
mvn -pl my-project-aj-dependencyJarWithoutAJ exec:java
然后你应该在控制台上看到类似这样的东西:
(...)
[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。
这是我的情况:
我有一个 Maven 项目 my-project-aj-dependency
由两个 jar 模块组成:
my-project-aj-dependencyJarWithAJ
(我有一个 Inter-type declaration,请参阅下方AppWithAj_Ahah.aj
方面的ahah()
方法)my-project-aj-dependencyJarWithoutAJ
我的问题是我想在第二个模块中使用在第一个模块方面定义的一些声明方法,但可能我错过了一些东西。

其中 AppWithAj.java
是:

public class AppWithAj {
public static void main( String[] args ){
System.out.println( "Hello World!" );
}
}
和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:

public class App {
public static void main( String[] args ) {
System.out.println( "Hello World! " + new AppWithAj().ahah());

我用这个 pom 配置让它工作:

这里我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(尽管如果您只是启动它就可以正常工作,对于 eclipse 这不是错误,顺便说一下,这不允许您使用自动完成广告用 wanings 填充代码...)。这是快照:
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,还不错。
- 但是声明的方面只影响它自己的模块中的一个 class,通过 ITD 扩展它。因此,无需在仅调用 AJ 模块中的方法的纯 Java 模块上使用 AJ 编译器。被调用的方法是由 ITD 创建的是无关紧要的,对于另一个模块来说它看起来就像正常的 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 classes 之一。 AJ 运行时依赖是可传递的,应该自动使用。
更新:
您要的是 POM,这里有。

请注意:我添加了 Exec Maven 插件只是为了演示目的,所以你可以这样做:
mvn clean install
mvn -pl my-project-aj-dependencyJarWithoutAJ exec:java
然后你应该在控制台上看到类似这样的东西:
(...)
[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。
