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:
package webservicesample.generated; // original type: ['java:webservicesample']:AwbModel public class AwbModel implements java.io.Serializable { public AwbModel() {} public AwbModel(java.lang.String p__A8 , java.lang.String p_a1 , java.lang.String p_a2 , java.lang.String p_a3 , java.lang.String p_a4 , java.lang.String p_a7) { this._A8 = p__A8; this.a1 = p_a1; this.a2 = p_a2; this.a3 = p_a3; this.a4 = p_a4; this.a7 = p_a7; } private java.lang.String _A8 ; /** <br> Derived from _a8. <br> schema name = ['java:webservicesample']:_a8 <br> schema type = ['http://www.w3.org/2001/XMLSchema']:string <br> schema formQualified = true */ public java.lang.String get_A8() { return _A8; } public void set_A8(java.lang.String v) { this._A8 = v; } private java.lang.String a1 ; /** <br> Derived from a1. <br> schema name = ['java:webservicesample']:a1 <br> schema type = ['http://www.w3.org/2001/XMLSchema']:string <br> schema formQualified = true */ public java.lang.String getA1() { return a1; } public void setA1(java.lang.String v) { this.a1 = v; } private java.lang.String a2 ; /** <br> Derived from a2. <br> schema name = ['java:webservicesample']:a2 <br> schema type = ['http://www.w3.org/2001/XMLSchema']:string <br> schema formQualified = true */ public java.lang.String getA2() { return a2; } public void setA2(java.lang.String v) { this.a2 = v; } private java.lang.String a3 ; /** <br> Derived from a3. <br> schema name = ['java:webservicesample']:a3 <br> schema type = ['http://www.w3.org/2001/XMLSchema']:string <br> schema formQualified = true */ public java.lang.String getA3() { return a3; } public void setA3(java.lang.String v) { this.a3 = v; } private java.lang.String a4 ; /** <br> Derived from a4. <br> schema name = ['java:webservicesample']:a4 <br> schema type = ['http://www.w3.org/2001/XMLSchema']:string <br> schema formQualified = true */ public java.lang.String getA4() { return a4; } public void setA4(java.lang.String v) { this.a4 = v; } private java.lang.String a7 ; /** <br> Derived from A7. <br> schema name = ['java:webservicesample']:A7 <br> schema type = ['http://www.w3.org/2001/XMLSchema']:string <br> schema formQualified = true */ public java.lang.String getA7() { return a7; } public void setA7(java.lang.String v) { this.a7 = v; } public java.lang.String toString() { return "AwbModel" + "{" + " _A8=<" + get_A8() + ">" + " a1=<" + getA1() + ">" + " a2=<" + getA2() + ">" + " a3=<" + getA3() + ">" + " a4=<" + getA4() + ">" + " a7=<" + getA7() + ">" + " }"; } public boolean equals(java.lang.Object __other__) { if (__other__ == this) return true; if (__other__ instanceof AwbModel) { AwbModel __obj__ = (AwbModel) __other__; return true && (_A8==null ? __obj__.get_A8()==null : _A8.equals(__obj__.get_A8())) && (a1==null ? __obj__.getA1()==null : a1.equals(__obj__.getA1())) && (a2==null ? __obj__.getA2()==null : a2.equals(__obj__.getA2())) && (a3==null ? __obj__.getA3()==null : a3.equals(__obj__.getA3())) && (a4==null ? __obj__.getA4()==null : a4.equals(__obj__.getA4())) && (a7==null ? __obj__.getA7()==null : a7.equals(__obj__.getA7())) ; } return false; } public int hashCode() { int __hash__result__ = 17; __hash__result__ = 37*__hash__result__ + (_A8==null ? 0 : _A8.hashCode()) ; __hash__result__ = 37*__hash__result__ + (a1==null ? 0 : a1.hashCode()) ; __hash__result__ = 37*__hash__result__ + (a2==null ? 0 : a2.hashCode()) ; __hash__result__ = 37*__hash__result__ + (a3==null ? 0 : a3.hashCode()) ; __hash__result__ = 37*__hash__result__ + (a4==null ? 0 : a4.hashCode()) ; __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
/// <remarks/> [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "4.0.30319.225")] [System.SerializableAttribute()] [System.Diagnostics.DebuggerStepThroughAttribute()] [System.ComponentModel.DesignerCategoryAttribute("code")] [System.Xml.Serialization.SoapTypeAttribute(Namespace="java:webservicesample")] public partial class AwbModel : object, System.ComponentModel.INotifyPropertyChanged { private string _a8Field; private string a1Field; private string a2Field; private string a3Field; private string a4Field; private string a7Field; /// <remarks/> [System.Xml.Serialization.SoapElementAttribute(IsNullable=true)] public string _a8 { get { return this._a8Field; } set { this._a8Field = value; this.RaisePropertyChanged("_a8"); } } /// <remarks/> [System.Xml.Serialization.SoapElementAttribute(IsNullable=true)] public string a1 { get { return this.a1Field; } set { this.a1Field = value; this.RaisePropertyChanged("a1"); } } /// <remarks/> [System.Xml.Serialization.SoapElementAttribute(IsNullable=true)] public string a2 { get { return this.a2Field; } set { this.a2Field = value; this.RaisePropertyChanged("a2"); } } /// <remarks/> [System.Xml.Serialization.SoapElementAttribute(IsNullable=true)] public string a3 { get { return this.a3Field; } set { this.a3Field = value; this.RaisePropertyChanged("a3"); } } /// <remarks/> [System.Xml.Serialization.SoapElementAttribute(IsNullable=true)] public string a4 { get { return this.a4Field; } set { this.a4Field = value; this.RaisePropertyChanged("a4"); } } /// <remarks/> [System.Xml.Serialization.SoapElementAttribute(IsNullable=true)] public string A7 { get { return this.a7Field; } set { this.a7Field = value; this.RaisePropertyChanged("A7"); } } public event System.ComponentModel.PropertyChangedEventHandler PropertyChanged; protected void RaisePropertyChanged(string propertyName) { System.ComponentModel.PropertyChangedEventHandler propertyChanged = this.PropertyChanged; if ((propertyChanged != null)) { propertyChanged(this, new System.ComponentModel.PropertyChangedEventArgs(propertyName)); } } }
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(); }
