webService调用浅谈（二）

第二种使用java语言调用webservice方法如下：

第二种方法使用的httpclient的方法，需要引入的包为apache的包

import org.apache.*

下面是测试代码：

 public String updateLeechdom() throws Exception

{

　　//首先定义访问的格式和头，这部分的由来最简单的办法就是直接将对方提供的webservice地址在浏览器中访问获取　　

　　//注意用转义符处理特殊符号

　　String xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?> ";
      xml = xml + "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"          xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">";
      xml = xml + "<soap:Body>";
      xml = xml + "<function1 xmlns=\"namespace\">";
      xml = xml +    "<para1>" + para1 + "</para1>";
      xml = xml + "<para2>" + para2 + "</para2>";
       xml = xml + "</function2>";
      xml = xml + "</soap:Body>";
      xml = xml + "</soap:Envelope>";

　　//用来盛放返回值

      String result ="";

      PostMethod postMethod = new  PostMethod(webServiceURL);
      HttpClientParams httpClientParams = new HttpClientParams();

　　//设置链接的访问时间
      httpClientParams.setConnectionManagerTimeout(999999);

　　//设置超时时间
      httpClientParams.setSoTimeout(999999);

　　//创建http线程
      MultiThreadedHttpConnectionManager connectionManager = new MultiThreadedHttpConnectionManager();
      HttpClient httpClient = new HttpClient(httpClientParams,connectionManager);
      postMethod.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,new DefaultHttpMethodRetryHandler(11, true));
      try

      {

　　//设置返回值的编码格式
       postMethod.setRequestEntity(new StringRequestEntity(xml, "text/xml", "GBK"));
       postMethod.addRequestHeader("Connection", "close");

　　//设置一个返回的状态值用以判断是否调用webservice成功
       int statusCode = httpClient.executeMethod(postMethod);
       if (statusCode != HttpStatus.SC_OK) {
       } else {

　　//下面还是老规矩进行流和字符串之间的转换
          InputStream out = postMethod.getResponseBodyAsStream();
         BufferedReader in = new BufferedReader(new InputStreamReader(out));
         StringBuffer buffer = new StringBuffer();
         String line = "";
         while ((line = in.readLine()) != null){
           buffer.append(line);
         }
         result = buffer.toString();

       }
     } catch (Exception e) {
 
     } finally {
        postMethod.releaseConnection();
     }
        return result;

}

下面是第一种调用方式的传送门，感兴趣的朋友可以也去看看。
