1、public class PayToolUtil { /** * 是否签名正确,规则是:按参数名称a-z排序,遇到空值的参数不参加签名。 * @return boolean */ public static boolean isTenpaySign(String characterEncoding, SortedMap<Object, Object> packageParams, String API_KEY) { StringBuffer sb = new StringBuffer(); Set es = packageParams.entrySet(); Iterator it = es.iterator(); while(it.hasNext()) { Map.Entry entry = (Map.Entry)it.next(); String k = (String)entry.getKey(); String v = (String)entry.getValue(); if(!"sign".equals(k) && null != v && !"".equals(v)) { sb.append(k + "=" + v + "&"); } } sb.append("key=" + API_KEY);

3、/** * @author * @date 2016-4-22 * @Description：将请求参数转换为xml格式的string * @param parameters * 请求参数 * @return */ public static String getRequestXml(SortedMap<Object, Object> parameters) { StringBuffer sb = new StringBuffer(); sb.append("<xml>"); Set es = parameters.entrySet(); Iterator it = es.iterator(); while (it.hasNext()) { Map.Entry entry = (Map.Entry) it.next(); String k = (String) entry.getKey(); String v = (String) entry.getValue(); if ("attach".equalsIgnoreCase(k) || "body".equalsIgnoreCase(k) || "sign".equalsIgnoreCase(k)) { sb.append("<" + k + ">" + "<![CDATA[" + v + "]]></" + k + ">"); } else { sb.append("<" + k + ">" + v + "</" + k + ">"); } } sb.append("</xml>"); return sb.toString(); }

5、/** * 获取当前时间 yyyyMMddHHmmss * * @return String */ public static String getCurrTime() { Date now = new Date(); SimpleDateFormat outFormat = new SimpleDateFormat("yyyyMMddHHmmss"); String s = outFormat.format(now); return s; } }

7、这些方法都是工具类，可以直接复制到工程里面直接使用
