具有特定参数注释和类型的Spring AOP执行匹配方法

Question

给定以下方法:

public void doSth(@AnnotationA @AnnotationB SomeType param) {
...do sth...
}

和@Aspect与以下@Around建议:

@Around("execution(* *(.., @com.a.b.AnnotationA (*), ..))") 

是否有可能修改上述表达式以匹配带有@AnnotationA和SomeType类型注释的参数的方法，并将这两者之间和AnnotationA之前的任何内容通配符?

类似(* @com.a.b.AnnotationA * SomeType)的东西，因此以下方法将匹配:

doSth(@AnnotationA @AnnotationB SomeType param) 
doSth(@AnnotationB @AnnotationA SomeType param) 
doSth(@AnnotationA SomeType param) 

提前感谢。

辅助类:

package de.scrum_master.app;
public class SomeType {}

package de.scrum_master.app;
import static java.lang.annotation.RetentionPolicy.RUNTIME;
import java.lang.annotation.Retention;
@Retention(RUNTIME)
public @interface AnnotationA {}

package de.scrum_master.app;
import static java.lang.annotation.RetentionPolicy.RUNTIME;
import java.lang.annotation.Retention;
@Retention(RUNTIME)
public @interface AnnotationB {}

驱动应用程序:

package de.scrum_master.app;
public class Application {
public static void main(String[] args) {
Application application = new Application();
SomeType someType = new SomeType();
application.one(11, someType, "x");
application.two(someType, new Object());
application.three(12.34D, someType);
application.four(22, someType, "y");
application.five(56.78D, someType);
}
// These should match
public void one(int i, @AnnotationA @AnnotationB SomeType param, String s) {}
public void two(@AnnotationB @AnnotationA SomeType param, Object o) {}
public void three(double d, @AnnotationA SomeType param) {}
// These should not match
public void four(int i, @AnnotationB SomeType param, String s) {}
public void five(double d, SomeType param) {}
}

方面:

package de.scrum_master.aspect;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
@Aspect
public class MyAspect {
@Before("execution(* *(.., @de.scrum_master.app.AnnotationA (de.scrum_master.app.SomeType), ..))")
public void intercept(JoinPoint joinPoint) {
System.out.println(joinPoint);
}
}

控制台日志:

execution(void de.scrum_master.app.Application.one(int, SomeType, String))
execution(void de.scrum_master.app.Application.two(SomeType, Object))
execution(void de.scrum_master.app.Application.three(double, SomeType))
