webservice练习（cxf，axis，httpclient）

需要的jar包：

代码如下：

 1 package com.dyf.client;
 2 
 3 import java.io.IOException;
 4 import java.net.MalformedURLException;
 5 import java.net.URL;
 6 import java.rmi.RemoteException;
 7 
 8 import javax.xml.namespace.QName;
 9 import javax.xml.rpc.ServiceException;
10 
11 import org.apache.axis.AxisFault;
12 import org.apache.axis.client.Call;
13 import org.apache.axis.client.Service;
14 import org.apache.axis.encoding.XMLType;
15 import org.apache.cxf.endpoint.Client;
16 import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
17 import org.apache.cxf.transport.http.HTTPConduit;
18 import org.apache.cxf.transports.http.configuration.HTTPClientPolicy;
19 import org.apache.http.Header;
20 import org.apache.http.client.config.RequestConfig;
21 import org.apache.http.client.methods.CloseableHttpResponse;
22 import org.apache.http.client.methods.HttpGet;
23 import org.apache.http.impl.client.CloseableHttpClient;
24 import org.apache.http.impl.client.HttpClients;
25 
26 public class SimpleClient {
27     
28     public static void main(String[] args){
29         CloseableHttpClient httpclient = HttpClients.createDefault();
30         RequestConfig requestConfig = RequestConfig.custom()
31                 .setSocketTimeout(1000)
32                 .setConnectTimeout(1000)
33                 .build(); 
34         
35         HttpGet httpGet1 = new HttpGet("http://www.baidu.com");
36         httpGet1.setConfig(requestConfig);
37         CloseableHttpResponse response1;
38         try {
39             response1 = httpclient.execute(httpGet1);
40             Header[] headers =response1.getAllHeaders();
41             for (Header header : headers) {
42                 System.out.println(header.toString());
43             }
44         } catch (IOException e) {
45             e.printStackTrace();
46         }
47         
48         //axis
49          Call call;
50         try {
51             call = (Call) new Service().createCall();
52             call.setTargetEndpointAddress(new URL("http://localhost:9001/Service/HelloWorld"));
53             QName methodObj = new QName("http://service.dyf.com/","getValue");
54             call.setOperationName(methodObj);
55 //            call.addParameter("arg0", XMLType.XSD_ANYTYPE,ParameterMode.IN);//接口的参数  
56             call.addParameter("arg0", null, null);
57             call.setReturnType(XMLType.XSD_STRING);//设置返回类型
58             Object[] paras ={"dashen"};
59             Object res = call.invoke(paras);
60             System.out.println(res);
61         } catch (ServiceException e) {
62             e.printStackTrace();
63         } catch (MalformedURLException e) {
64             e.printStackTrace();
65         } catch (AxisFault e) {
66             e.printStackTrace();
67         } catch (RemoteException e) {
68             e.printStackTrace();
69         }
70         
71         //cxf01
72         try {
73             Client client = JaxWsDynamicClientFactory.newInstance().createClient("http://localhost:9002/Service/HelloWorld4j?wsdl");
74             HTTPConduit http = (HTTPConduit) client.getConduit();
75             HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
76             http.setClient(httpClientPolicy);
77             Object[] res = client.invoke("getValue", "dashen");
78             System.out.println(res[0]);
79         } catch (Exception e) {
80             e.printStackTrace();
81         }
82         
83         
84         
85     }
86 }

 其中遇到的错误：

Exception in thread "main" java.lang.NoSuchMethodError: javax.wsdl.xml.WSDLReader.readWSDL(Ljavax/wsdl/xml/WSDLLocator;Lorg/w3c/dom/Element;)Ljavax/wsdl/Definition; 

 

java.lang.ClassNotFoundException: com/sun/tools/internal/xjc/api/XJC 问题,最后发现是因为配置jdk环境的时候用的是jre，改成jdk就可以了

jar包冲突问题；在tomcat下lib下有个wsdl-1.5.jar,而在cxf中则要使用的wsdl-1.6.jar;

需注意的地方：

cxf的地址后需加上“？wsdl”；

axis：传值是按照arg0，arg1传入的，所以只需在addParameter中设置arg0，arg1就可以了。

 

本文值是练习，欢迎多多指正，共同学习。
