Java发布一个简单 webservice应用 并发送SOAP请求

一、创建并发布一个简单的webservice应用

　　1、webservice 代码：

　　

1 package com.ls.demo;
2
3 import javax.jws.WebMethod;
4 import javax.jws.WebService;
5 import javax.xml.ws.Endpoint;
6
7
8 @WebService
9 public class HelloWorld {
10     @WebMethod
11     public String sayHello(String str){
12         System.out.println("get Message...");
13         String result = "Hello World, "+str;
14         return result;
15     }
16     public static void main(String[] args) {
17         System.out.println("server is running");
18         String address="http://localhost:9000/HelloWorld";
19         Object implementor =new HelloWorld();
20         Endpoint.publish(address, implementor);
21     }
22
23 }

 

　　2、运行项目，并访问 "http://localhost:9000/HelloWorld?wsdl"，得到如下wsdl文件，说明webservice发布成功：

37         </port>
38     </service>
39 </definitions>

 

二、客户端访问webservice

　　1、通过 HttpClient 及  HttpURLConnection 发送SOAP请求，代码如下：

　　

1 import java.io.BufferedReader;
2 import java.io.DataOutputStream;
3 import java.io.InputStream;
4 import java.io.InputStreamReader;
5 import java.net.HttpURLConnection;
6 import java.net.URL;
7
8 import org.apache.commons.httpclient.HttpClient;
9 import org.apache.commons.httpclient.methods.PostMethod;
10 import org.apache.commons.httpclient.methods.RequestEntity;
11 import org.apache.commons.httpclient.methods.StringRequestEntity;
12 import org.apache.commons.io.IOUtils;
13
14 public class TestHelloWrold {
15     public static void main(String[] args) throws Exception {
16         String wsdl = "http://localhost:9000/HelloWorld?wsdl";
17         int timeout = 10000;
18         StringBuffer sb = new StringBuffer("");
19         sb.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
20         sb.append("<soap:Envelope "
21                 + "xmlns:api='http://demo.ls.com/' "
22                 + "xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' "
23                 + "xmlns:xsd='http://www.w3.org/2001/XMLSchema' "
24                 + "xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'>");
25         sb.append("<soap:Body>");
26         sb.append("<api:sayHello>");
27         sb.append("<arg0>ls</arg0>");
28         sb.append("</api:sayHello>");
29         sb.append("</soap:Body>");
30         sb.append("</soap:Envelope>");
31
32
33
34         // HttpClient发送SOAP请求
35         System.out.println("HttpClient 发送SOAP请求");
36         HttpClient client = new HttpClient();
37         PostMethod postMethod = new PostMethod(wsdl);
38         // 设置连接超时
39         client.getHttpConnectionManager().getParams().setConnectionTimeout(timeout);
40         // 设置读取时间超时
41         client.getHttpConnectionManager().getParams().setSoTimeout(timeout);
42         // 然后把Soap请求数据添加到PostMethod中
43         RequestEntity requestEntity = new StringRequestEntity(sb.toString(), "text/xml", "UTF-8");
44         //设置请求头部，否则可能会报 “no SOAPAction header” 的错误
45         postMethod.setRequestHeader("SOAPAction","");
46         // 设置请求体
47         postMethod.setRequestEntity(requestEntity);
48         int status = client.executeMethod(postMethod);
49         // 打印请求状态码
50         System.out.println("status:" + status);
51         // 获取响应体输入流
52         InputStream is = postMethod.getResponseBodyAsStream();
53         // 获取请求结果字符串
54         String result = IOUtils.toString(is);
55         System.out.println("result: " + result);
56
57
58
59         // HttpURLConnection 发送SOAP请求
60         System.out.println("HttpURLConnection 发送SOAP请求");
61         URL url = new URL(wsdl);
62         HttpURLConnection conn = (HttpURLConnection) url.openConnection();
63
64         conn.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
65         conn.setRequestMethod("POST");
66         conn.setUseCaches(false);
67         conn.setDoInput(true);
68         conn.setDoOutput(true);
69         conn.setConnectTimeout(timeout);
70         conn.setReadTimeout(timeout);
71
72         DataOutputStream dos = new DataOutputStream(conn.getOutputStream());
73         dos.write(sb.toString().getBytes("utf-8"));
74         dos.flush();
75
76
77         BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream(), "utf-8"));
78         String line = null;
79         StringBuffer strBuf = new StringBuffer();
80         while ((line = reader.readLine()) != null) {
81             strBuf.append(line);
82         }
83         dos.close();
84         reader.close();
85
86         System.out.println(strBuf.toString());
87     }
88
89 }

 

　　响应报文如下：

　　

<?xml version="1.0" ?>
　　<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
　　　　<S:Body>
　　　　　　<ns2:sayHelloResponse xmlns:ns2="http://demo.ls.com/">
　　　　　　　　<return>Hello World, ls</return>
　　　　　　</ns2:sayHelloResponse>
　　　　</S:Body>
　　</S:Envelope>

　　问：SOAP的请求报文的格式是怎么来的呢？

　　答：可用Eclipse测试WSDL文件，则可得到想要的SOAP请求及响应报文，具体步骤如下图：

 

第一步：



 

第二步：

 通过第一步，会在浏览器打开如下的页面



　　

　　2、生成客户端代码访问

　　　a、通过 "wsimport"（JDK自带）命令生成客户端代码。进入命令行模式，执行 wsimport -s . http://localhost:9000/HelloWorld?wsdl，就会在当前目录下生成客户端代码。附图：

 


　　b、通过Eclipse生成客户端代码
