AspectJ 1.9.4 with OpenJDK 11 Without Spring Context 不作为 Spark 路由的依赖模块工作

Question

我正在尝试使用 AspectJ 创建自定义加载时注释，在没有 Spring 上下文的情况下打开 JDK11。它在模块中运行良好，注释在 class 加载时编织，方面在运行时执行。没问题，但是当 aspectJ 实现模块添加为对另一个具有 spark 路由的模块的依赖时。 AspectJ 和注释不在处理中。我是否缺少任何配置？

好吧，首先你忘了将 Spark Core 添加到应用程序模块的依赖项中，你只在父 POM 的依赖项管理部分定义了版本。否则 Maven 项目甚至不会因为未知的导入而编译。

此外，我在对您的的评论中告诉您的同样适用：

You attach the Java agent via command line, just like you do for the test.

作为示例，我将 Exec Maven 插件添加到您的应用程序 POM 并将其配置为运行您的示例主程序 class:

<!-- (...) -->

  <properties>
    <main-class>de.scrum_master.app.CounterApp</main-class>
  </properties>

<!-- (...) -->

      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>exec-maven-plugin</artifactId>
        <configuration>
          <executable>java</executable>
          <arguments>
            <argument>
              -javaagent:${settings.localRepository}/org/aspectj/aspectjweaver/${aspectj.version}/aspectjweaver-${aspectj.version}.jar
            </argument>
            <argument>-classpath</argument>
            <!-- automatically creates the classpath using all project dependencies, also adding the project build directory -->
            <classpath/>
            <argument>${main-class}</argument>
          </arguments>
        </configuration>
      </plugin>

<!-- (...) -->

然后您运行您的构建，随后运行应用程序：

$ mvn clean install
(...)

$ cd application

$ mvn exec:exec
(...)

然后调用您的 URL http://localhost:4567/counter 并检查运行ning 服务器的控制台输出：

execution(void de.scrum_master.app.MyCounter.count()) -> call_count
