Axis2快速上手指南4

使用ADB生成一个客户端
执行以下步骤来使用Axis Data Binding(ADB)构建一个客户端。
通过在Axis2_HOME/samples/quickstartadb目录键入以下命令来生成客户端数据绑定:
%AXIS2_HOME%/bin/WSDL2Java -uri resources/META-INF/StockQuoteService.wsdl -p samples.quickstart.clients -d adb -s
-o build/client
或者在Axis2_HOME/samples/quickstartadb目录简单的键入ant generate.client。
下一步看看quickstartadb/src/samples/quickstart/clients/ADBClient.java，并看看它在Code Listing 10中是怎样定义的。
Code Listing 10:ADBClient类

package samples.quickstart.clients;

import samples.quickstart.service.adb.StockQuoteServiceStub;

public class ADBClient{
    public static void main(java.lang.String args[]){
        try{
             StockQuoteServiceStub stub =
                new StockQuoteServiceStub
                 ("http://localhost:8080/axis2/services/StockQuoteService");

             getPrice(stub);
             update(stub);

         } catch(Exception e){
             e.printStackTrace();
             System.err.println("\n\n\n");
         }
     }

    /* fire and forget */
    public static void update(StockQuoteServiceStub stub){
        try{
             StockQuoteServiceStub.Update req = new StockQuoteServiceStub.Update();
             req.setSymbol ("ABC");
             req.setPrice (42.35);

             stub.update(req);
             System.err.println("done");
         } catch(Exception e){
             e.printStackTrace();
             System.err.println("\n\n\n");
         }
     }

    /* two way call/receive */
    public static void getPrice(StockQuoteServiceStub stub){
        try{
             StockQuoteServiceStub.GetPrice req = new StockQuoteServiceStub.GetPrice();

             req.setSymbol("ABC");

             StockQuoteServiceStub.GetPriceResponse res =
                 stub.getPrice(req);

             System.err.println(res.get_return());
         } catch(Exception e){
             e.printStackTrace();
             System.err.println("\n\n\n");
         }
     }

}

package samples.quickstart.clients;  import samples.quickstart.service.adb.StockQuoteServiceStub;  public class ADBClient{     public static void main(java.lang.String args[]){         try{             StockQuoteServiceStub stub =                 new StockQuoteServiceStub                 ("http://localhost:8080/axis2/services/StockQuoteService");              getPrice(stub);             update(stub);          } catch(Exception e){             e.printStackTrace();             System.err.println("\n\n\n");         }     }      /* fire and forget */     public static void update(StockQuoteServiceStub stub){         try{             StockQuoteServiceStub.Update req = new StockQuoteServiceStub.Update();             req.setSymbol ("ABC");             req.setPrice (42.35);              stub.update(req);             System.err.println("done");         } catch(Exception e){             e.printStackTrace();             System.err.println("\n\n\n");         }     }      /* two way call/receive */     public static void getPrice(StockQuoteServiceStub stub){         try{             StockQuoteServiceStub.GetPrice req = new StockQuoteServiceStub.GetPrice();              req.setSymbol("ABC");              StockQuoteServiceStub.GetPriceResponse res =                 stub.getPrice(req);              System.err.println(res.get_return());         } catch(Exception e){             e.printStackTrace();             System.err.println("\n\n\n");         }     }  }

该类使用你创建的Axis Data Bindings创建一个客户端存根。然后它在Web服务上调用getPrice和update操作。getPrice方法操作创建
GetPrice有效载荷并设置symbol为ABC。然后它发送请求并显示当前价格。update方法创建一个Update有效载荷，设置symbol为ABC及
price为42.35。
现在通过在Axis2_HOME/samples/quickstartadb目录键入ant run.client来构建并运行客户端。
你应该得到以下输出:

42
done

42 done

使用XMLBeans生成一个客户端
执行以下步骤来使用XMLBeans数据绑定来构建一个客户端。
通过在xmlbeansClient目录键入以下命令来生成数据绑定:
%AXIS2_HOME%/bin/WSDL2Java -uri resources/META-INF/StockQuoteService.wsdl -p samples.quickstart.service.xmlbeans -d
xmlbeans -s -o build/client
或者简单的在Axis2_HOME/samples/quickstartxmlbeans目录下键入ant generate.client。
注意这只会创建客户端存根代码而不会创建服务器端代码。
下一步看看quickstartxmlbeans/src/samples/quickstart/clients/XMLBEANSClient.java，并在Code Listing 11看看它怎样定义的

             getPrice(stub);
             update(stub);

         } catch(Exception e){

             System.err.println("\n\n\n");
         }
     }

             UpdateDocument.Update req = reqDoc.addNewUpdate();
             req.setSymbol ("ABC");
             req.setPrice (42.32);

             stub.update(reqDoc);
             System.err.println("done");
         } catch(Exception e){
