我试图创建从另一个项目（testMaven）调用的项目（test5）的方法的建议。我已经将test5项目作为依赖项包含在testMaven的pom.xml中，并在testMaven的类中设置了一个建议，但仍未执行。方法（dfg）的调用工作正常。
这是它的代码：
MainApp.java（testMaven）
package testMaven;
import test5.yxc;
public class MainApp {
public static void main(String[] args) {
yxc b = new yxc();
b.dfg(2);
}
}
yxc.java（test5）
package test5;
public class yxc {
public void dfg(int a){
System.out.println(a);
}
}
testAspect.java（testMaven）
package testMaven;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.annotation.Before;
import test5.yxc;
@Aspect
public class testAspect {
@Before("execution(* test5.yxc.dfg(..))")
public void testBefore(){
System.out.println("yooi");
}
}
pom.xml（testMaven）

你能帮我这是怎么回事吗？谢谢
最佳答案
在testMaven中签入代码，并签出代码并按如下所示更改POM：

注意：添加了程序集插件，以使自己的测试/验证更加容易。
当我编译项目时，我在maven中看到以下记录：
[INFO] --- aspectj-maven-plugin:1.8:compile (AspectJ-Classes) @ testMaven ---
[INFO] Showing AJC message detail for messages of types: [error, warning, fail]
[INFO] Join point 'method-execution(void testMaven.aaaa.aa(int))' in Type 'testMaven.aaaa' (aaaa.java:5) advised by before advice from 'testMaven.aspecter' (aspecter.java:10)
现在，按如下所示执行jar时，会看到以下结果：
...>java -cp target/testMaven-0.0.1-SNAPSHOT-jar-with-dependencies.jar testMaven/MainApp
yooi
2
鉴于MainApp如下：
package testMaven;
public class MainApp {
public static void main(String[] args) {
// TODO Auto-generated method stub
aaaa a = new aaaa();
a.aa(2);
}
}
启动的类将打印传递的参数
package testMaven;
public class aaaa {
public void aa(int a){
System.out.println(a);
}
}
和拦截器如下
package testMaven;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.annotation.Before;
@Aspect
public class aspecter {
@Before("execution(* testMaven.aaaa.aa(..))")
public void testBefore(){
System.out.println("yooi");
}
}
我会说它有效:)
