如何在另一个中介类中调用类中介属性值 [英] How to call Class mediator property value inside another mediator Class

问题描述

我需要在另一个中介类中调用一些类中介属性值

I need to call some Class mediator property value inside another mediator Class

这是我的 SurepayMediator 课程

This is my SurepayMediator class

package esb.cellcard.billing;    
public class SurepayMediator extends AbstractMediator{
    public boolean mediate(MessageContext context) { 
      context.setProperty("firstValue", "Run Fast");

      if(something){
          //Here I need to execute AddSubscription class 
      }
      else {
         //Here I need to execute CancleSubscription class 
      }
      return true;
   }
}

我需要在 AddSubscription 类和 CancelSubscription 类中调用这个 firstValue

I need to call this firstValue inside the AddSubscription class and CancelSubscription class

添加订阅

package esb.cellcard.billing;

public class AddSubscription extends AbstractMediator{

SurepayMediator sm = new SurepayMediator();

public boolean mediate(MessageContext context) { 
    //I need to call that firstValue in here
    return true;
  }
}

取消订阅

package esb.cellcard.billing;

public class CancelSubscription extends AbstractMediator{

 SurepayMediator sm = new SurepayMediator();

 public boolean mediate(MessageContext context) { 
   //I need to call that firstValue in here
   return true;
 }
}

推荐答案

看来只有SurepayMediator"才应该是类中介(您需要从中介中调用的唯一中介).

It seems that only "SurepayMediator" should be a class mediator (the only one you need to call from your mediation).

更改类 AddSubscription 和 CancelSubscription，使它们不扩展 AbstractMediator.

Change classes AddSubscription and CancelSubscription so that they do not extends AbstractMediator.

最终，重命名mediate"方法并从 SurepayMediator 使用 MessageContext 参数调用它:您将获得firstValue"属性的值，调用 context.getProperty("firstValue");

Eventually, rename 'mediate' method and call it from SurepayMediator with the MessageContext parameter : you will get "firstValue" property's value calling context.getProperty("firstValue");

 if(something){
          addSubscription.add(context); 
      }

.

public class AddSubscription{
  public boolean add(MessageContext context) { 
    //I need to call that firstValue in here
    String value = context.getProperty("firstValue");
    ...
    return true;
  }
}
