java学习：调用 java web service

先写一个java的class:AwbModel(相当于要在web service中传输的实体对象)

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!";
    }


}

　　然后再写一个Awb类(相当于web service的接口+实现)

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环境下，封装成web service发布到weblogic后，WSDL的内容见下图:

　

注意：因为A5只有get方法，A6只有set方法，最终生成的WSDL自动去掉了这二个“属性”(后面在用c#调用该java web Service时，能看到这将会生成真正意义上的.net property)，自定义的其它方法(比如sayHelloA)被丢弃(即：这类方法没有自动序列化)，同时比较有意思的是"_a8"，AwbModel.java里只定义了set_a8(String value),get_a8()方法，根本没有声明_a8的private变量，但是java自动视为已经存在“_a8”的私有成员；此外直接声明的public变量，WSDL里不改变大小写，仍然还是A7；而其它的setXXX,getXXX方法，最终一律去掉set/get后，将首字母小写，即xXX。

类似vs.net里添加服务引用后，会自动生成xxxClient、xxxChannel、代理类等客户端调用代码一样，make之后，jBuilder也会生成客户端代码示例包Awb_Client.jar，解压后看下AwbModel.java的内容:

    __hash__result__ = 37*__hash__result__ + (a7==null ? 0 : a7.hashCode()) ;
    

    return __hash__result__;
  }

}

　　

与WSDL里看到的基本一致，不过跟原始的AwbModel.java相比，还是有一些有趣的小变化：原始AwbModel.java里定义的私成成员，一律变成了小写，而自动添加的"_A8"却又是大写。

下面看看用java如何调用web service：

随便新建一个java项目，把jBuilder自动生成的Awb_client.jar包引用进来

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();
        }
    }
}

　　

这样就能调用了.

.net当然也能调用java写的web service，在vs.net里添加服务引用，服务地址输入:http://127.0.0.1:7001/MyWebService/Awb?WSDL vs.net会象添加wcf/asmx服务引用一样，自动生成代理类等其它代码，看看自动生成的AwbModel类

可以发现，刚才截图里的a1、a2、a3、a4、A7、_a8全都以属性(property)的方式出现了。

c#的调用代码还是一如继往的简单：

            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();
            }
