WebService从服务端到客户端的用例

1、首先编写Wsdl（基于契约优先的方式），要注意的是命名空间（若是使用include或import）最好使用一致的，代码如下：

 <?xml version="1.0" encoding="UTF-8" standalone="no"?>
 <wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
                 xmlns:tns="http://www.xiaoqiaolv/ws"
                 xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
                 xmlns:xsd="http://www.w3.org/2001/XMLSchema"
                 name="UserServiceImpl"
                 targetNamespace="http://www.xiaoqiaolv/ws">
   <wsdl:types>
     <xsd:schema targetNamespace="http://www.xiaoqiaolv/ws">
      <!-- <xsd:include schemaLocation="UserSchema.xsd"/> -->
      <!-- <xsd:import namespace="http://www.xiaoqiaolv/ws" schemaLocation="UserSchema.xsd"/>-->

         <xsd:element name="add" type="tns:add"/>
         <xsd:element name="addResponse" type="tns:addResponse"/>
         <xsd:element name="delete" type="tns:delete"/>
         <xsd:element name="deleteResponse" type="tns:deleteResponse"/>
         <xsd:element name="login" type="tns:login"/>
         <xsd:element name="loginResponse" type="tns:loginResponse"/>

         <xsd:complexType name="add">
             <xsd:sequence>
                 <xsd:element name="user" type="tns:user"/>
             </xsd:sequence>
         </xsd:complexType>
         <xsd:complexType name="addResponse">
             <xsd:sequence/>
         </xsd:complexType>

         <xsd:complexType name="delete">
             <xsd:sequence>
                 <xsd:element name="username" type="xsd:string"/>
             </xsd:sequence>
         </xsd:complexType>
         <xsd:complexType name="deleteResponse">
             <xsd:sequence/>
         </xsd:complexType>

         <xsd:complexType name="list">
             <xsd:sequence/>
         </xsd:complexType>
         <xsd:complexType name="listResponse">
             <xsd:sequence minOccurs="0" maxOccurs="unbounded">
                 <xsd:element name="user" type="tns:user"/>
             </xsd:sequence>
         </xsd:complexType>

         <xsd:complexType name="login">
             <xsd:sequence>
                 <xsd:element name="username" type="xsd:string"/>
                 <xsd:element name="password" type="xsd:string"/>
             </xsd:sequence>
         </xsd:complexType>
         <xsd:complexType name="loginResponse">
             <xsd:sequence/>
         </xsd:complexType>
         <xsd:complexType name="user">
             <xsd:sequence>
                 <xsd:element name="id" type="xsd:int"/>
                 <xsd:element name="username" type="xsd:string"/>
                 <xsd:element name="password" type="xsd:string"/>
             </xsd:sequence>
         </xsd:complexType>
     </xsd:schema>
   </wsdl:types>

   <wsdl:message name="addMessage">
     <wsdl:part element="tns:add" name="add"/>

   <wsdl:binding name="userBinding" type="tns:UserService">
     <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
     <wsdl:operation name="add">

     <wsdl:operation name="list">

         <soap:body use="literal"/>
       </wsdl:output>
     </wsdl:operation>
   </wsdl:binding>
   <wsdl:service name="UserServiceImpl">
     <wsdl:port binding="tns:userBinding" name="UserServiceImplPort">
       <soap:address location="http://localhost:9999/ws"/>
     </wsdl:port>
   </wsdl:service>
 </wsdl:definitions>

2、实现服务器端的应用实现，这个就不加代码了，根据wsdl文档用wsimport生成服务，只取出接口service，然后其他的和我们正常的web开发都一致。

3、服务端发布服务：public static void main(String[] args) {
        Endpoint.publish("http://localhost:9999/ws", new UserServiceImpl());
    }

4、实现客户端：根据服务网址http://localhost:9999/ws，生成服务，得到所有以.java为后缀的类，把整个包包含在自己的项目中

5、编写测试类：代码如下：

 public class Test {
     private UserService userService;
     private UserServiceImpl userServiceImpl;

     public void testWsdl(){
         try {
             URL url = new URL("http://localhost:9999/ws?wsdl");
             QName  qname = new QName("http://www.xiaoqiaolv/ws","UserServiceImpl");
             userServiceImpl = new UserServiceImpl(url,qname);
             userService = userServiceImpl.getUserServiceImplPort();
             User user = new User();
             user.setUsername("aaa");
             user.setPassword("1111");
             user.setId(21212);
             userService.add(user);
             List<User> list = userService.list();
             for(User u:list){
                 System.out.println(u.getUsername());
             }
         } catch (MalformedURLException e) {
             // TODO Auto-generated catch block
             e.printStackTrace();
         }

     }
     public static void main(String[] args) {
         new Test().testWsdl();
     }
 }

6、有问题的话可以打开tcpmon，对接口服务进行监听，查看客户端与服务端传递的信息java -jar tcpmon.jar
