用到的jar包有：
commons-codec-1.3.jar
commons-httpclient-3.0.jar
commons-logging-1.0.4.jar
具体流程大致这样：
String soapRequestData = "<?xml version=""1.0"" encoding=""utf-8""?>" +
"<soap12:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap12=""http://www.w3.org/2003/05/soap-envelope"">" +
"<soap12:Body>" +
" <qqCheckOnline xmlns=""http://WebXml.com.cn/"">" +
" <qqCode>349104641</qqCode>" +
" </qqCheckOnline>" +
" </soap12:Body>" +
"</soap12:Envelope>";
System.out.println(soapRequestData);
//PostMethod postMethod = new PostMethod("http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl");
PostMethod postMethod = new PostMethod("http://www.webxml.com.cn/webservices/qqOnlineWebService.asmx?wsdl");
// 然后把Soap请求数据添加到PostMethod中
byte[] b = soapRequestData.getBytes("utf-8");
InputStream is = new ByteArrayInputStream(b,0,b.length);
RequestEntity re = new InputStreamRequestEntity(is,b.length,"application/soap+xml; charset=utf-8");
postMethod.setRequestEntity(re);
//最后生成一个HttpClient对象，并发出postMethod请求
HttpClient httpClient = new HttpClient();
int statusCode = httpClient.executeMethod(postMethod);
String soapResponseData = postMethod.getResponseBodyAsString();
System.out.print(soapResponseData);
动态构造调用串的话如下实现：
private String tns;
private String methodName;
private String wsdlLocation;
private String soapResponseData;
private int invoke(Map<String, String> patameterMap) throws Exception {
PostMethod postMethod = new PostMethod(wsdlLocation);
String soapRequestData = buildRequestData(patameterMap);
byte[] bytes = soapRequestData.getBytes("utf-8");
InputStream inputStream = new ByteArrayInputStream(bytes, 0,
bytes.length);
RequestEntity requestEntity = new InputStreamRequestEntity(inputStream,
bytes.length, "application/soap+xml; charset=utf-8");
postMethod.setRequestEntity(requestEntity);
HttpClient httpClient = new HttpClient();
int statusCode = httpClient.executeMethod(postMethod);
soapResponseData = postMethod.getResponseBodyAsString();
return statusCode;
}
private String buildRequestData(Map<String, String> patameterMap) {
StringBuffer soapRequestData = new StringBuffer();
soapRequestData.append("<?xml version=""1.0"" encoding=""utf-8""?>");
soapRequestData
.append("<soap12:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap12=""http://www.w3.org/2003/05/soap-envelope"">");
soapRequestData.append("<soap12:Body>");
soapRequestData.append("<" + methodName + " xmlns=""" + tns + """>");
Set<String> nameSet = patameterMap.keySet();
for (String name : nameSet) {
soapRequestData.append("<" + name + ">" + patameterMap.get(name)
+ "</" + name + ">");
}
soapRequestData.append("</" + methodName + ">");
soapRequestData.append("</soap12:Body>");
soapRequestData.append("</soap12:Envelope>");
return soapRequestData.toString();
}
