使用XStream进行对象和xml的转换，极度舒适

XStream xStream = new XStream();
        XStream.setupDefaultSecurity(xStream);
        xStream.allowTypesByRegExp(new String[] { ".*" });
        xStream.alias("Body",CmlabsReturn.ReportListResult.class);
        xStream.alias("Result",CmlabsReturn.UpLoadAppReturn.class);
        xStream.alias("Records",CmlabsReturn.Records.class);
        xStream.alias("results",CmlabsReturn.Results.class);
        xStream.alias("PdfList",CmlabsReturn.PdfList.class);
        xStream.alias("PDF",CmlabsReturn.PDF.class);
        Object result = (CmlabsReturn.ReportListResult) xStream.fromXML(xmlString);
