整理了一下用的Utils,更新一下哈！
1、DocType
/**
* 定義了報表輸出型別，固定了可輸出型別
*
* @author
*
*/
public enum DocType {
PDF, HTML, XLS,XLSX, XML, RTF, CSV, TXT, DOC
}2、DocTypeUtil
/** * 匹配格式 * * @author * */ public class DocTypeUtil { /** * 預設型別pdf * @param docType * @return */ public static DocType getEnumDocType(String docType) { DocType type = DocType.PDF; docType = docType.toUpperCase(); if (docType.equals("DOC")) { type = DocType.DOC; } else if (docType.equals("XLS")) { type = DocType.XLS; } else if(docType.equals("XLSX")) { type = DocType.XLSX; }else if (docType.equals("XML")) { type = DocType.XML; } else if (docType.equals("RTF")) { type = DocType.RTF; } else if (docType.equals("CSV")) { type = DocType.CSV; } else if (docType.equals("HTML")) { type = DocType.HTML; } else if (docType.equals("TXT")) { type = DocType.TXT; } return type; } }
3、JasperreportUtils
