java學習：調用 java web service

先寫一個java的class:AwbModel(相當於要在web service中傳輸的實體物件)

package webservicesample;public class AwbModel {    private String _a1 = "_a1";    public String getA1() {        return _a1;    }    public void setA1(String value) {        this._a1 = value;    }    private String _A2 = "_A2";    public String getA2() {        return _A2;    }    public void setA2(String value) {        this._A2 = value;    }    private String a3 = "a3";    public String getA3() {        return a3;    }    public void setA3(String value) {        this.a3 = value;    }    private String A4 = "A4";    public String getA4() {        return A4;    }    public void setA4(String value) {        this.A4 = value;    }    private String A5 = "A5";    public String getA5() {        return A5;    }    private String A6 = "A6";    public void setA6(String value) {        this.A6 = value;    }    public String A7 = "A7";    //private String _a8="a8";    public String get_a8(){        //return _a8;        return "";    }    public void set_a8(String value){        //this._a8=value;    }    public String sayHelloA(){        return "Hello!";    }}

　　然後再寫一個Awb類(相當於web service的介面+實現)

package webservicesample;public class Awb {    public AwbModel GetAwbModelByNo() {        AwbModel a = new AwbModel();        a.setA1("a1_new");        return a;    }    private String _b1 = "_b1";    public String getB1() {        return _b1;    }    public void setB1(String value) {        this._b1 = value;    }    private String _B2 = "_B2";    public String getB2() {        return _B2;    }    public void setB2(String value) {        this._B2 = value;    }    private String b3 = "b3";    public String getB3() {        return b3;    }    public void setB3(String value) {        this.b3 = value;    }    private String B4 = "B4";    public String getB4() {        return B4;    }    public void setB4(String value) {        this.B4 = value;    }    private String B5 = "B5";    public String getB5() {        return B5;    }    private String B6 = "B6";    public void setB6(String value) {        this.B6 = value;    }    public String B7 = "B7";    public String sayHelloB() {        return "Hello B!";    }}

　jBuilder2006環境下，封裝成web service發布到weblogic後，WSDL的內容見:

　

注意：因為A5隻有get方法，A6隻有set方法，最終產生的WSDL自動去掉了這二個“屬性”(後面在用c#調用該java web Service時，能看到這將會產生真正意義上的.net property)，自訂的其它方法(比如sayHelloA)被丟棄(即：這類方法沒有自動序列化)，同時比較有意思的是"_a8"，AwbModel.java裡只定義了set_a8(String value),get_a8()方法，根本沒有聲明_a8的private變數，但是java自動視為已經存在“_a8”的私人成員；此外直接聲明的public變數，WSDL裡不改變大小寫，仍然還是A7；而其它的setXXX,getXXX方法，最終一律去掉set/get後，將首字母小寫，即xXX。

類似vs.net裡加入服務參考後，會自動產生xxxClient、xxxChannel、代理類等用戶端調用代碼一樣，make之後，jBuilder也會產生用戶端程式碼範例包Awb_Client.jar，解壓後看下AwbModel.java的內容:

與WSDL裡看到的基本一致，不過跟原始的AwbModel.java相比，還是有一些有趣的小變化：原始AwbModel.java裡定義的私成成員，一律變成了小寫，而自動添加的"_A8"卻又是大寫。

下面看看用java如何調用web service：

隨便建立一個java項目，把jBuilder自動產生的Awb_client.jar包引用進來

package jmyang.web_service_call;import webservicesample.generated.*;import java.io.IOException;import javax.xml.rpc.ServiceException;public class wsCallDemo {    public void callService() {        String wsdlUrl = "http://127.0.0.1:7001/MyWebService/Awb?WSDL";        try {            Awb service = new Awb_Impl(wsdlUrl);            AwbPort port = service.getAwbPort();            AwbModel result = port.getAwbModelByNo();            System.out.println("awbmodel.a1=" + result.getA1());        } catch (IOException e) {            e.printStackTrace();        } catch (ServiceException e2) {            e2.printStackTrace();        }    }}

　　

這樣就能調用了.

.net當然也能調用java寫的web service，在vs.net裡加入服務參考，服務地址輸入:http://127.0.0.1:7001/MyWebService/Awb?WSDL vs.net會象添加wcf/asmx服務引用一樣，自動組建代理程式類等其它代碼，看看自動產生的AwbModel類

可以發現，剛才裡的a1、a2、a3、a4、A7、_a8全都以屬性(property)的方式出現了。

c#的調用代碼還是一如繼往的簡單：

            using (YJM.AwbPortClient client = new AwbPortClient())            {                var model = client.GetAwbModelByNo();                Console.WriteLine("a1=" + model.a1);                Console.WriteLine("a2=" + model.a2);                Console.WriteLine("a3=" + model.a3);                Console.WriteLine("a4=" + model.a4);                Console.WriteLine("A7=" + model.A7);                Console.WriteLine("_a8=" + model._a8);                Console.Read();            }
