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;@WebService
public 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

<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" ><web-app> <listener>
<listener-class>com.shyroke.listener.MyListener</listener-class>
</listener> <servlet>
<servlet-name>testServlet</servlet-name>
<servlet-class>com.shyroke.servlet.TestServlet</servlet-class>
</servlet> <servlet-mapping>
<servlet-name>testServlet</servlet-name>
<url-pattern>/servlet/TestServlet</url-pattern>
</servlet-mapping>
</web-app>
