WebService的调用有很多种方式，本地调用（静态调用），远程调用（动态）
关于上边静态，动态是我个人的理解，没有权威性，个人喜好而已
本地调用
具体操作请看：http://www.jianshu.com/p/1e9582a4b340
远程调用
远程调用的方式比较多，例如利用cxf，axis、axis2 、HttpClient等框架的调用，这里具体看基于HttpClient的调用, HttpClient 3和4 使用方式稍有区别，经测试，4.5.2版本不支持jdk1.5
- HttpClient 3.x
public static String doPostSOAP_RemoveUser(String logonName){
Properties prop = new Properties();
PostMethod post = null;
String responseXml = null;
String json= null;
try {
InputStream in = HttpClient3_0_SOAPUtil.class.getResourceAsStream("/sysPath.properties");
prop.load(in);
String postURL = prop.getProperty("postURL");
post = new PostMethod(postURL);
post.setRequestHeader("Content-Type","text/xml;charset=utf-8");
//File input = new File(strXMLFilename);
// Prepare HTTP post
// Request content will be retrieved directly
// from the input stream
String systemId = prop.getProperty("systemId");
String strWSDLXml_RemoveUser = ""
+ ""
+ " "
+ " "
+ " "
+ " "+systemId+" "
+ " "
+ " "+logonName+" "
+ " "
+ " "
+ " ";
System.out.println(strWSDLXml_RemoveUser);
String strSoapAction_RemoveUser = prop.getProperty("strSoapAction_RemoveUser");
byte[] b = strWSDLXml_RemoveUser.getBytes("utf-8");
InputStream is = new ByteArrayInputStream(b,0,b.length);
RequestEntity entity = new InputStreamRequestEntity(is,b.length,"application/soap+xml; charset=utf-8");
post.setRequestEntity(entity);
// consult documentation for your web service
post.setRequestHeader("SOAPAction", strSoapAction_RemoveUser);
// Get HTTP client
HttpClient httpclient = new HttpClient();
// Execute request
int result = httpclient.executeMethod(post);
// Display status code
//System.out.println("Response status code: " + result);
// Display response
//System.out.println("Response body: ");
responseXml = post.getResponseBodyAsString();
//System.out.println(responseXml);
Document document_ret = DocumentHelper.parseText(responseXml);
json = document_ret.getRootElement().element("Body").element("RemoveUserResponse").element("RemoveUserResult").getText();
}catch (Exception e) {
e.printStackTrace();
} finally {
// Release current connection to the connection pool once you are done
post.releaseConnection();
}
return json;
}
这是我个人根据相应业务而产生的代码，不同业务可根据业务需求做相应的改动,strWSDLXml_RemoveUser 这个字符串是在soapUI 中得到，

关于soapUI我也是小白，不多做解释，具体自行百度、google。
上述代码使用了到了外部配置文件
sysPath 内容如下
systemId=xxxxxxxxxxxxxxxxxxxx
postURL=http://xxx.xxx.xxx.xxx:9999/webservice/externalservice/userservice.asmx
strSoapAction_RemoveUser=http://xxxxxx.xxx/RemoveUse
jar 包依赖关系

调用上述方法，将会得到调用webService后的响应内容
下边给出3.x的官方提供的示例

public static String doPostSoap1_1(String postUrl, String soapXml,
String soapAction) {
String retStr = "";
// 创建HttpClientBuilder
HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();
// HttpClient
CloseableHttpClient closeableHttpClient = httpClientBuilder.build();
HttpPost httpPost = new HttpPost(postUrl);
// 设置请求和传输超时时间
RequestConfig requestConfig = RequestConfig.custom()
.setSocketTimeout(socketTimeout)
.setConnectTimeout(connectTimeout).build();
httpPost.setConfig(requestConfig);
try {
httpPost.setHeader("Content-Type", "text/xml;charset=UTF-8");
httpPost.setHeader("SOAPAction", soapAction);
StringEntity data = new StringEntity(soapXml,
Charset.forName("UTF-8"));
httpPost.setEntity(data);
CloseableHttpResponse response = closeableHttpClient.execute(httpPost);
HttpEntity httpEntity = response.getEntity();
if (httpEntity != null) {
// 打印响应内容
retStr = EntityUtils.toString(httpEntity, "UTF-8");
System.out.println("response:" + retStr);
}
// 释放资源
closeableHttpClient.close();
} catch (Exception e) {
// logger.error("exception in doPostSoap1_1", e);
e.printStackTrace();
}
return retStr;
}
public static void main(String[] args) {
String systemId = "ssss";
String jsonUserInfo="";
String adduser = ""
+ ""
+ " "
+ " "
+ " "
+ " "+systemId+" "
+ " "
+ " "+jsonUserInfo+" "
+ " "

String postUrl = "http://1xxx.xxx.x.x:9999/webservice/externalservice/userservice.asmx";
String repXml= doPostSoap1_1(postUrl, adduser, "http://tempuri.org/AddUser");
}
之后解析repXml得到响应的json 字符串；
