获取接口数据-HttpClient

1.调用接口方法，使用HttpClient，请求报文为xml格式（返回数据 xml，中间使用标签包含json数据）

//传送报文和路径进行接口调用
  public String send(String url, String soapXmlData) {
    String responseBody = "";
        PostMethod post = new PostMethod(url);
        System.out.println("接口发送内容为：" + soapXmlData);
        int state;
    try {
      RequestEntity requestEntity = new StringRequestEntity(soapXmlData,"text/xml","UTF-8");
      post.setRequestEntity(requestEntity);
      HttpClient httpClient = new HttpClient();
      state = httpClient.executeMethod(post);
      responseBody = new String(post.getResponseBodyAsString());
      System.out.println("调用状态是：" + state);
      System.out.println("返回消息是：" + responseBody);
    } catch (Exception e) {
      e.printStackTrace();
      throw new MisException(e);
    }
    return responseBody;
  }

//对返回数据解析成map（返回xml的json数据，解析）
//返回map类型的json数据，但需要进行解析xml标签获取json数据
  public Map sendXmlData(String url, String soapXmlData){
    Map respDataMap = new HashMap();
    String respdata = "";
    
    try {
      respdata = send(url, soapXmlData.toString());
      respDataMap = XMLUtil.doXMLParse(respdata);
    } catch (Exception e){
      e.printStackTrace();
    }
    return respDataMap;
  }      

2.使用xml报文，将报文中参数设置成参数，传map进行进行对应

/**
   * 根据模板字符串生成内容
   * @param strTemplate 模板信息
   * @param map 数据信息
   * @return
   */
  public static String publishHtml(String strTemplate, Map<String, Object> map) {
    //Open Declaration freemarker.template.Configuration
    Configuration cfg = new Configuration();
    String content = null;
    StringWriter stringWriter = new StringWriter(); // 将数据模型和模板合并
    //获取编码格式
    String encoding ="gbk";
    try {
      cfg.setTemplateLoader(new StringTemplateLoader(strTemplate));  
      cfg.setDefaultEncoding(encoding);
      cfg.setOutputEncoding(encoding);
      cfg.setLocale(Locale.CHINA);
      cfg.setNumberFormat("0.####");
      cfg.setTagSyntax(Configuration.AUTO_DETECT_TAG_SYNTAX);
      Template template = cfg.getTemplate("");
      template.setEncoding(encoding);
      template.process(map, stringWriter);
      content = stringWriter.toString();
      stringWriter.flush();
    } catch (IOException e) {
      throw new MisException(e);
    } catch (TemplateException e) {
      throw new MisException(e);
    }  finally {
      if (stringWriter != null) {
        try {
          stringWriter.close();
        } catch (Exception ex) {
          ex.printStackTrace();
        }
      }
    }
    return content;
  }
