4.WSDL文档

请求Web Service

import com.atguigu.day01_ws.ws.HelloWS;import com.atguigu.day01_ws.ws.HelloWSImplService;public class ClientTest {    public static void main(String[] args) {        HelloWSImplService factory = new HelloWSImplService();        HelloWS hellWS = factory.getHelloWSImplPort();        String result = hellWS.sayHello("BOB");        System.out.println("client "+result);    }}

WSDL文档结构

WSDL文档图解

5.使用框架开发Web Service

Apache CXF继承了 Celtix 和 XFire 两大开源项目的精华，提供了对JAX-WS全面的支持，并且提供了多种 Binding 、DataBinding、Transport 以及各种 Format 的支持，并且可以根据实际项目的需要，采用代码优先（Code First）或者 WSDL 优先（WSDL First）来轻松地实现 Web Services 的发布和使用。

Apache CXF支持的数据类型有：int、float、String、自定义类型、集合、数组、List、Set、Map。

5.1 Web Service的请求流程

使用Apache CXF框架开发Web Service需要将相关的jar包导入到项目的类路径下，并且客户端使用wsdl2java命令生成客户端代码。

5.2 Apache CXF的拦截器

为了在Web Service请求过程中，能动态操作请求和响应数据，Apache CXF设计了拦截器。

package org.apache.cxf.interceptor;import org.apache.cxf.message.Message;/** * Base interface for all interceptors. */public interface Interceptor
    
      {    /**     * Intercepts a message.      * Interceptors should NOT invoke handleMessage or handleFault     * on the next interceptor - the interceptor chain will     * take care of this.     *      * @param message     */    void handleMessage(T message) throws Fault;        /**     * Called for all interceptors (in reverse order) on which handleMessage     * had been successfully invoked, when normal execution of the chain was     * aborted for some reason.     *      * @param message     */    void handleFault(T message);}
    

5.3 用Apache CXF编写基于Spring的Web Service

5.3.1 服务器端

beans.xml

web.xml

    
      
     
      day02_ws_cxf_spring
       
         
      
       index.html
          
      
       index.htm
          
      
       index.jsp
          
      
       default.html
          
      
       default.htm
          
      
       default.jsp
        
         
       
           
      
       contextConfigLocation
            
      
       classpath:beans.xml
         
           
        
           
      
                org.springframework.web.context.ContextLoaderListener      
         
           
        
           
      
       CXFServlet
            
      
                org.apache.cxf.transport.servlet.CXFServlet      
            
      
       1
         
        
           
      
       CXFServlet
            
      
       /*
          
     
    

5.3.2 客户端

client-beans.xml

测试

public class ClientTest {    public static void main(String[] args) {        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[]  {"client-beans.xml"});        OrderWS orderWS = (OrderWS) context.getBean("orderClient");        Order order = orderWS.getOrderById(24);        System.out.println(order);    }}

5.4 通过Ajax请求Web Service

<%@ page language="java" contentType="text/html; charset=utf-8"    pageEncoding="utf-8"%>
        用户名:        
    AJax请求webservice

5.4.1 通过JQuery请求Web Service

<%@ page language="java" contentType="text/html; charset=utf-8"    pageEncoding="utf-8"%>
        用户名:        
    Jquery请求webservice

5.4.2 HttpUrlConnection请求WebService

<%@ page language="java" contentType="text/html; charset=utf-8"    pageEncoding="utf-8"%>
        用户名:        
    HttpURLConnection请求webservice

public class HttpURLConnectionServlet extends HttpServlet {    private static final long serialVersionUID = 1L;        protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {        String name = request.getParameter("name");        System.out.println("doPost "+name);                String data = "
    
     
      
       
        "+name+"
       
      
     
    ";        URL url = new URL("http://192.168.10.165:8888/day01_ws/datatypews");                HttpURLConnection connection = (HttpURLConnection) url.openConnection();                connection.setRequestMethod("POST");        connection.setDoOutput(true);        connection.setDoInput(true);        connection.setRequestProperty("Content-Type", "text/xml;charset=utf-8");                OutputStream os = connection.getOutputStream();        os.write(data.getBytes("utf-8"));                int responseCode = connection.getResponseCode();        if(responseCode==200) {            InputStream is = connection.getInputStream();//String xml            System.out.println("return "+is.available());                        response.setContentType("text/xml;charset=utf-8");            ServletOutputStream outputStream = response.getOutputStream();                        byte[] buffer = new byte[1024];            int len = 0;            while((len=is.read(buffer))>0) {                outputStream.write(buffer, 0, len);            }            outputStream.flush();        }    }}
