我追踪了你的一些老问题，试图找出你实际上想做什么。我想出了以下结构和代码，对我来说它运行良好。

我创建了两个不同的方面。一个使用@AspectJ注释，另一个被定义为经典的AspectJ方面。
AspectL.java
package com.stackoverflow.aspects;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
/**
* @author maba, 2012-09-18
*/
@Aspect
public class AspectL {
@Pointcut("execution(* main(..))")
public void defineEntryPoint() {
}
@Before("defineEntryPoint()")
public void aaa(JoinPoint joinPoint) {
System.out.println("aspect before");
}
@After("defineEntryPoint()")
public void bbb(JoinPoint joinPoint) {
System.out.println("aspect after");
}
}
Trace.aj
package com.stackoverflow.aspects;
public aspect Trace {
pointcut publicMethodExecuted(): execution(public !static * *(..));
after(): publicMethodExecuted() {
System.out.printf("Enters on method: %s. \n", thisJoinPoint.getSignature());
Object[] arguments = thisJoinPoint.getArgs();
for (int i =0; i < arguments.length; i++){
Object argument = arguments[i];
if (argument != null){
System.out.printf("With argument of type %s and value %s. \n", argument.getClass().toString(), argument);
}
}
System.out.printf("Exits method: %s. \n", thisJoinPoint.getSignature());
}
}
这两个文件是 ProjectA 模块的一部分，也是 jar 的一部分。
现在我们想使用这些方面，并将它们编织到 ProjectB 的代码中。
ProjectB/pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0"

</executions>
<configuration>
<mainClass>com.stackoverflow.App</mainClass>
</configuration>
</plugin>
</plugins>
</build>
</project>
App.java
package com.stackoverflow;
/**
* @author maba, 2012-09-17
*/
public class App {
public void hello(String name) {
}
public static void main(String[] args) {
App app = new App();
app.hello("world");
}
}
我从top pom构建所有内容：
mvn clean install
然后进入 ProjectB 目录并运行应用：
mvn exec:java
结果是：
aspect before
Enters on method: void com.stackoverflow.App.hello(String).
With argument of type class java.lang.String and value world.
Exits method: void com.stackoverflow.App.hello(String).
aspect after
因此，得出的结论是，这两个方面都在工作，maven设置也有效。
