问题描述

我对MXBean自定义类型有问题,我无法处理.这是我的java结构,涉及到Map< enum, OtherThing>属性

I have a problem with MXBean custom types and I am not able to handle it. This is my java structure, that involves Map< enum, OtherThing> attribute

PPV及其界面

public class PPV implements PPVMXBean {

   public enum EnumPV {
      PV1,
      PV2;
   }

   public static Map<EnumPV, PV> list;

   public Map<EnumPV, PV> getList() {
       return list;
   }
}

public interface PPVMXBean {
    public Map<EnumPV, PV> getList();
}

PV及其界面

public class PV implements PVBean {

   public enum EnumTP {
      TP1,
      TP2;
   }

   private Map<EnumTP, EnumP[]> mapP;
   private Map<EnumTP, EnumP[]> mapC;
   private Map<EnumTP, EnumP[]> mapT;
   private Map<EnumTP, EnumP[]> mapV;

   public Map<EnumTP, EnumP[]> getMapP() {
      return mapP;
   }

   public Map<EnumTP, EnumP[]> getMapC() {
      return mapC;
   }

   public Map<EnumTP, EnumP[]> getMapT() {
      return mapT;
   }

   public Map<EnumTP, EnumP[]> getMapV() {
      return mapV;
   }
}

public interface PVBean {
    public Map<EnumTP, EnumP[]> getMapP();
    public Map<EnumTP, EnumP[]> getMapC();
    public Map<EnumTP, EnumP[]> getMapT();
    public Map<EnumTP, EnumP[]> getMapV();
}

枚举

public enum EnumP {
    P1(1),
    P2(2);

    private int p;

    EnumP (int pAux) {
        p = pAux;
    }

    public int getP() {
       return p;
    }
}

有了这些,我得到:

...
Caused by: javax.management.NotCompliantMBeanException: com.example.PPVMXBean: Method com.example.PPVMXBean.getLista has parameter or return type that cannot be translated into an open type
...
Caused by: java.lang.IllegalArgumentException: Method com.example.PPVMXBean.getLista has parameter or return type that cannot be translated into an open type
...
Caused by: javax.management.openmbean.OpenDataException: Cannot convert type: java.util.Map<com.example.PPV$EnumPV, com.examplePV>
...
Caused by: javax.management.openmbean.OpenDataException: Cannot convert type: class com.example.PV
...
Caused by: javax.management.openmbean.OpenDataException: Cannot convert type: java.lang.Class<?>
...
Caused by: javax.management.openmbean.OpenDataException: Cannot convert type: java.lang.Class<?>

我做错了什么?问题出在哪里?

What am I doing wrong? Where is the problem?

推荐答案

编写时:

public interface PVBean {
    public Map<EnumTP, EnumP[]> getMapP();
    public Map<EnumTP, EnumP[]> getMapC();
    public Map<EnumTP, EnumP[]> getMapT();
    public Map<EnumTP, EnumP[]> getMapV();
}

... EnumTP 的范围如何?

... how is EnumTP in scope?
