java - 将信息从应用程序传递到处理程序级 SOAP

Question

我正在使用 SOAP Web 服务，我需要将信息从应用程序级别(我的主要客户端类)传递到客户端处理程序级别以进行进一步评估。我在下面列出了我的客户和我的客户处理程序。我想扫描来自用户的值并将其存储在位于处理程序中的“discountVal”变量中，以便我可以将文本节点添加到 SOAPHeader。

客户:

package client;

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
import javax.xml.ws.handler.Handler;
import javax.xml.ws.handler.HandlerResolver;
import javax.xml.ws.handler.PortInfo;

/**

public class Client 
{

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {

       client.ItemPriceServiceService service = new client.ItemPriceServiceService();
       service.setHandlerResolver(new ClientHandlerResolver());
       client.ItemPriceService port = service.getItemPriceServicePort();




       String discount = "25";


       Scanner scan = new Scanner(System.in);  
       String item = scan.next();
       while(!item.equals("bye"))
       {
        double price = getPrice(item);

        System.out.println(price);

        item = scan.next();
       }
       if(item.equals("bye"))
       {
           System.exit(0);
       }
    }

    private static double getPrice(java.lang.String arg0) {
        client.ItemPriceServiceService service = new client.ItemPriceServiceService();
        client.ItemPriceService port = service.getItemPriceServicePort();
        return port.getPrice(arg0);
    }

    private static class ClientHandlerResolver implements HandlerResolver {

        public ClientHandlerResolver() {
        }

        @Override
        public List<Handler> getHandlerChain(PortInfo portInfo) {

            List<Handler> hchain = new ArrayList<Handler>();
            hchain.add(new clientHandler());
            return hchain;
        }
    }
}

    public void close(MessageContext context) {

}

任何帮助将不胜感激!我感觉使用 MessageContext 是一种方法，但我不确定从哪里开始。

你是对的，使用 MessageContext 是一种将信息从客户端实现传递到处理程序的方法。方法如下:

1) 向客户端类添加

((BindingProvider)port).getRequestContext().put("discountID", discount);

2) 然后到处理程序

if(context.containsKey("discountID")){
     discountVal = context.get("discountID");
}

仅此而已。
