一、解决方法

　　A . 编写一个监听器，在监听器中发布服务

 

二、案例一

• 方法A：编写一个监听器，在监听器中发布服务

 

　　1. 　　编写服务接口

package com.shyroke.service;import javax.jws.WebParam;import javax.jws.WebResult;import javax.jws.WebService;@WebServicepublic interface IFirst {    @WebResult(name = "addResult")    public int add(@WebParam(name = "x") int x, @WebParam(name = "y") int y);}

 

　　2.　　实现服务接口

package com.shyroke.service;import javax.jws.WebParam;import javax.jws.WebResult;import javax.jws.WebService;@WebService(endpointInterface = "com.shyroke.service.IFirst")public class IFirstImpl implements IFirst {    public int add(int x, int y) {        return x + y;    }}

 

　　3.　　在监听器中发布

package com.shyroke.listener;import javax.crypto.EncryptedPrivateKeyInfo;import javax.servlet.ServletContextEvent;import javax.servlet.ServletContextListener;import javax.xml.ws.Endpoint;import com.shyroke.service.IFirstImpl;public class MyListener implements ServletContextListener {    public void contextInitialized(ServletContextEvent arg0) {        System.out.println("项目初始化。。");        /**         * 发布服务         */        Endpoint.publish("http://localhost:3030/web_webService", new IFirstImpl());        System.out.println("发布服务。。。。。。");    }    public void contextDestroyed(ServletContextEvent arg0) {        System.out.println("项目销毁。。");    }}

　　4.　　 编写servlet

package com.shyroke.servlet;import java.io.IOException;import java.io.PrintWriter;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;public class TestServlet extends HttpServlet {    @Override    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {        this.doPost(req, resp);    }    @Override    protected void doPost(HttpServletRequest request, HttpServletResponse response)            throws ServletException, IOException {        request.setCharacterEncoding("UTF-8");        response.setContentType("text/html;charset=UTF-8");        PrintWriter out = response.getWriter();        out.print("这是一个servlet");        out.flush();        out.close();    }}

 

　　5.　　web.xml配置监听器和servlet

             
                  
       
        com.shyroke.listener.MyListener
               
          
              
       
        testServlet
               
       
        com.shyroke.servlet.TestServlet
           
              
              
       
        testServlet
               
       
        /servlet/TestServlet
           
      
     

 

　　6.　　结果

 

 

• 缺陷

  • 　　通过监听器发布的web服务，web服务的端口和web工程的端口是不能一致的，否则就会报错。
