Java6 WebService学习

参考了网络上中资料，自己学习实践了一个Java6 WebService.

首先，建立一个WebService:

package garfield;

import javax.jws.WebService;
import javax.xml.ws.Endpoint;


@WebService
public class MyJ6WebService {
        public String SayHello(String strName) {
                return "Hello ,"+strName+"!";
        }

        public static void main(String[] args) {
                //发布WebService,注意如果提示：Exception in thread "main" com.sun.xml.internal.ws.server.ServerRtException: Server Runtime Error: java.net.BindException: Address already in use: bind
                //则需要修改一下发布端口
                Endpoint.publish("http://localhost:8030/garfield.MyJ6WebService", new MyJ6WebService());
                System.out.println("WebService was published success !");
        }
}

启动Tomcat，然后运行，系统会输出：WebService was published success !，表示WebService已启动。

可以在浏览器中输入地址：http://localhost:8030/garfield.MyJ6WebService?wsdl

显示WebService信息：

  </message>

  <output wsam:Action="http://garfield/MyJ6WebService/SayHelloResponse" message="tns:SayHelloResponse" /> 
  </operation>
  </portType>

  <soap:address location="http://localhost:8030/garfield.MyJ6WebService" /> 
  </port>
  </service>
  </definitions>

在WebService启动的状态下，在命令行中输入：

E:\Temp>wsimport -p garfield.garfieldj6wsclient -keep http://localhost:8030/garf
ield.MyJ6WebService?wsdl
parsing WSDL...


generating code...


compiling code...


E:\Temp>

注意，一定要对应你发布的WebService信息!

然后系统会自动生成相关的接口文件，如下：

新建Java工程，将输出文件引入，然后建立测试类：

package xxh;

import garfield.garfieldj6wsclient.*;

public class WebClient {
        /**  
         * @param args  
         */  
        public static void main(String[] args) {   
             //创建一个客户端服务对象 
            MyJ6WebService myJ6WS = new MyJ6WebServiceService().getMyJ6WebServicePort(); 
            //调用服务方法，并得到方法返回值 
            String strTest = myJ6WS.sayHello("Garfield"); 
            //打印服务的返回值 
            System.out.println(strTest); 
        }   
}

 在WebService运行情况下，运行客户端测试程序，输出：

Hello ,Garfield!
