webservice（六）基于契约优先的wsdl文件生成webservice服务代码实例

首先是介绍整个流程

契约优先开发流程
1.先编写schema或者wsdl文件
2.根据这个文件生成一个客户端代码
3.编写实现类（在实现类上指定wsdlLocation）
4.发布服务

创建wsdl
1.在类路径META-INF下创建wsdl
2.新建wsdl并且编写文件
    2.1编写type
    2.2编写message
    2.3编写portType指定接口和方法
    2.4编写binding指定编码样式
    2.5编写service（name要与命名空间名称一样）
3.根据名称生成服务器端代码
    进入wsdl文件夹内用wsimport -d D:\sid\workspace_webservice\wsimport -keep mywsdl.wsdl
    只留IMyService一个接口，其他的都删除
4.编写一个实现类实现接口
    
5.在实现类上指定wsdl的位置
    指定targetNameSpace与接口的一样(可以不指定，但是需要自己重新添加方法的返回标注等)
    @WebService(endpointInterface="org.example.mywsdl.IMyService",
            targetNamespace="http://www.example.org/mywsdl/",
            wsdlLocation="META-INF/wsdl/mywsdl.wsdl")
6.启动服务
    然后在启动时候可以热修改，直接修改wsdl文件
7.执行服务器wsimport，生成客户端代码
    wsimport -d D:\sid\workspace_webservice\wsimport -keep -verbose http://localhost:8989/ms?wsdl
    
8.加入header
    wsdl文件中修改：
      <!-- 定义头部信息 -->
      <xsd:element name="licenseInfo" type="xsd:string"/>
      <!-- 定义头信息 -->
      <wsdl:message name="licenseInfo">
          <wsdl:part name="licenseInfo" element="tns:licenseInfo"/>
      </wsdl:message>
      <!-- 在方法中加入头信息 -->
      <soap:header use="literal" part="licenseInfo" message="tns:licenseInfo"/>
      
    修改IMyService的add方法
    public int add(
        @WebParam(name = "a", targetNamespace = "")
        int a,
        @WebParam(name = "b", targetNamespace = "")
        int b,
        @WebParam(name = "licenseInfo", header=true)
        String licenseInfo);
    

代码如下：

   mywsdl.wsdl：

<?xml version="1.0" encoding="UTF-8" standalone="no"?><wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://www.example.org/mywsdl/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="mywsdl" targetNamespace="http://www.example.org/mywsdl/">  <wsdl:types>    <xsd:schema targetNamespace="http://www.example.org/mywsdl/">  <!-- 定义方法 -->    <xsd:element name="add" type="tns:add"/>    <xsd:element name="addResponse" type="tns:addResponse"/>    <xsd:element name="divide" type="tns:divide"/>    <xsd:element name="divideResponse" type="tns:divideResponse"/>    <!-- 定义头部信息 -->    <xsd:element name="licenseInfo" type="xsd:string"/>      <!-- 定义类型 -->    <xsd:complexType name="add">    <xsd:sequence>    <xsd:element name="a" type="xsd:int"/>    <xsd:element name="b" type="xsd:int"/>    </xsd:sequence>    </xsd:complexType>    <xsd:complexType name="addResponse">    <xsd:sequence>    <xsd:element name="addResult" type="xsd:int"/>    </xsd:sequence>    </xsd:complexType>    <xsd:complexType name="divide">    <xsd:sequence>    <xsd:element name="num1" type="xsd:int"/>    <xsd:element name="num2" type="xsd:int"/>    </xsd:sequence>    </xsd:complexType>    <xsd:complexType name="divideResponse">    <xsd:sequence>    <xsd:element name="divideResult" type="xsd:int"/>    </xsd:sequence>    </xsd:complexType>    </xsd:schema>  </wsdl:types>    <wsdl:message name="add">  <wsdl:part name="add" element="tns:add"/>  </wsdl:message>  <wsdl:message name="addResponse">  <wsdl:part name="addResponse" element="tns:addResponse"/>  </wsdl:message>  <wsdl:message name="divide">  <wsdl:part name="divide" element="tns:divide"/>  </wsdl:message>  <wsdl:message name="divideResponse">  <wsdl:part name="divideResponse" element="tns:divideResponse"/>  </wsdl:message>  <!-- 定义头信息 -->  <wsdl:message name="licenseInfo">  <wsdl:part name="licenseInfo" element="tns:licenseInfo"/>  </wsdl:message>    <wsdl:portType name="IMyService">    <wsdl:operation name="add">      <wsdl:input message="tns:add"/>      <wsdl:output message="tns:addResponse"/>    </wsdl:operation>    <wsdl:operation name="divide">      <wsdl:input message="tns:divide"/>      <wsdl:output message="tns:divideResponse"/>    </wsdl:operation>  </wsdl:portType>      <wsdl:binding name="myServiceSOAP" type="tns:IMyService">    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>    <wsdl:operation name="add">      <wsdl:input>        <soap:body use="literal"/>        <!-- 加入头信息 -->        <soap:header use="literal" part="licenseInfo" message="tns:licenseInfo"/>      </wsdl:input>      <wsdl:output>        <soap:body use="literal"/>      </wsdl:output>    </wsdl:operation>    <wsdl:operation name="divide">      <wsdl:input>        <soap:body use="literal"/>      </wsdl:input>      <wsdl:output>        <soap:body use="literal"/>      </wsdl:output>    </wsdl:operation>  </wsdl:binding>    <wsdl:service name="MyServiceImplService">    <wsdl:port binding="tns:myServiceSOAP" name="MyServiceImplPort">      <soap:address location="http://localhost:8989/ms"/>    </wsdl:port>  </wsdl:service></wsdl:definitions>

只留IMyservice类，并进行修改：

package org.example.mywsdl;import javax.jws.WebMethod;import javax.jws.WebParam;import javax.jws.WebResult;import javax.jws.WebService;import javax.xml.bind.annotation.XmlSeeAlso;import javax.xml.ws.RequestWrapper;import javax.xml.ws.ResponseWrapper;/** * This class was generated by the JAX-WS RI. * JAX-WS RI 2.2.4-b01 * Generated source version: 2.2 *  */@WebService(name = "IMyService", targetNamespace = "http://www.example.org/mywsdl/")public interface IMyService {    /**     *      * @param b     * @param a     * @return     *     returns int     */    @WebMethod    @WebResult(name = "addResult", targetNamespace = "")    @RequestWrapper(localName = "add", targetNamespace = "http://www.example.org/mywsdl/", className = "org.example.mywsdl.Add")    @ResponseWrapper(localName = "addResponse", targetNamespace = "http://www.example.org/mywsdl/", className = "org.example.mywsdl.AddResponse")    public int add(        @WebParam(name = "a", targetNamespace = "")        int a,        @WebParam(name = "b", targetNamespace = "")        int b,    @WebParam(name = "licenseInfo", header=true)    String licenseInfo);    /**     *      * @param num2     * @param num1     * @return     *     returns int     */    @WebMethod    @WebResult(name = "divideResult", targetNamespace = "")    @RequestWrapper(localName = "divide", targetNamespace = "http://www.example.org/mywsdl/", className = "org.example.mywsdl.Divide")    @ResponseWrapper(localName = "divideResponse", targetNamespace = "http://www.example.org/mywsdl/", className = "org.example.mywsdl.DivideResponse")    public int divide(        @WebParam(name = "num1", targetNamespace = "")        int num1,        @WebParam(name = "num2", targetNamespace = "")        int num2);}

创建实现类之后发布服务

package org.example.mywsdl;import javax.xml.ws.Endpoint;public class MyServer {public static void main(String[] args) {//地址是在wsdl中编写的Endpoint.publish("http://localhost:8989/ms", new MyServiceImpl());}}

根据服务器端生成客户端代码后：

wsimport -d D:\sid\workspace_webservice\wsimport -keep -verbose http://localhost:8989/ms?wsdl

加入测试类：

package org.example.test;import java.io.IOException;import java.net.MalformedURLException;import java.net.URL;import javax.xml.namespace.QName;import javax.xml.soap.MessageFactory;import javax.xml.soap.SOAPBody;import javax.xml.soap.SOAPBodyElement;import javax.xml.soap.SOAPEnvelope;import javax.xml.soap.SOAPException;import javax.xml.soap.SOAPHeader;import javax.xml.soap.SOAPMessage;import javax.xml.ws.Dispatch;import javax.xml.ws.Service;public class Test {public static void main(String[] args) {String ns = "http://www.example.org/mywsdl/";try {QName name = new QName(ns,"MyServiceImplService");URL url = new URL("http://localhost:8989/ms?wsdl");//MyServiceImplService mis = new MyServiceImplService(url,name);//IMyService ms = mis.getMyServiceImplPort();//System.out.println(ms.divide(19, 2));//使用soap来传递消息Service service = Service.create(url,name);QName pname = new QName(ns,"MyServiceImplPort");Dispatch<SOAPMessage> dispatch  = service.createDispatch(pname, SOAPMessage.class, Service.Mode.MESSAGE);SOAPMessage msg = MessageFactory.newInstance().createMessage();SOAPEnvelope enve = msg.getSOAPPart().getEnvelope();SOAPHeader header = enve.getHeader();SOAPBody body = enve.getBody();if (header==null) {header = enve.addHeader();}QName hname = new QName(ns,"licenseInfo","ns");header.addHeaderElement(hname).setValue("sssssssss");QName bname = new QName(ns,"add","ns");SOAPBodyElement ele = body.addBodyElement(bname);ele.addChildElement("a").setValue("12");ele.addChildElement("b").setValue("12");msg.writeTo(System.out);System.out.println("\n invoking。。。。。。。。");SOAPMessage rep = dispatch.invoke(msg);rep.writeTo(System.out);} catch (MalformedURLException e) {e.printStackTrace();} catch (SOAPException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}}
