AspectJ:通知不适用于数组类型

看起来该类型正在被展平,并被视为非数组类型(不适用于数组类型,而适用于非数组类型,与预期正好相反)。

简单复制

方面:

public aspect Aspect {
    after() : call(public MaybeMissingClass MaybeMissingClass.*())
    {
        System.out.println("Aspect: MaybeMissingClass 1");
    }
    after() : call(public MaybeMissingClass[] MaybeMissingClass.*())
    {
        System.out.println("Aspect: MaybeMissingClass[] 2");
    }
}

类别:

// compile all together
//      java -cp aspectjtools.jar;aspectjrt.jar org.aspectj.tools.ajc.Main -source 1.6 Aspect.aj Main.java
// compile aspect without concrete class in CP and then compile class
//      java -cp aspectjtools.jar;aspectjrt.jar org.aspectj.tools.ajc.Main -source 1.6 Aspect.aj
//      java -cp aspectjtools.jar;aspectjrt.jar org.aspectj.tools.ajc.Main -source 1.6 -aspectpath . Main.java

// run
//      java -cp .;aspectjtools.jar;aspectjrt.jar Main

import java.io.*;
import java.util.*;

public class Main {
    
    public static void main(String[] args) throws Exception {
        System.out.println("hello from main");
        MaybeMissingClass.f1();
        MaybeMissingClass.f2();
    }
}

class MaybeMissingClass {
    public static MaybeMissingClass f1(){System.out.println("hello from MaybeMissingClass.f1");return null;}
    public static MaybeMissingClass[] f2(){System.out.println("hello from MaybeMissingClass.f2");return null;}
}

一起编译时的输出:

hello from main
hello from MaybeMissingClass.f1
Aspect: MaybeMissingClass 1
hello from MaybeMissingClass.f2
Aspect: MaybeMissingClass[] 2

hello from main
hello from MaybeMissingClass.f1
Aspect: MaybeMissingClass 1
Aspect: MaybeMissingClass[] 2
hello from MaybeMissingClass.f2

有人能解释一下吗?

编辑
呼叫时维度信息似乎丢失 resolveBindingsForMissingType() 而不是 resolveBindingsForExactType() .
