一.面板上传该上传方式支持一次上传多个文件:使用说明:1.引入上传面板
var attachmentPanel = Ext.create("BeidaSoft.XTGL.attachment.AttachmentPanel", { height : 200, baseParams : { tableName : "test", // 业务表表名 recordID : "testRecordID", // 业务表主键 extParam : ‘AAAAA‘ // 面板标识,用于一个功能使用多个上传控件,对上传附件做区分 } });
2.界面展示
3.数据保存
attachmentPanel.baseParams.recordID = "testRecordID"; attachmentPanel.baseParams.tableName = "test"; attachmentPanel.baseParams.extParam = "AAAAA"; attachmentPanel.Save();
二.按钮上传
该上传方式一次只能上传一个文件
1.在js文件中加入var attachmentButton = Ext.create( "BeidaSoft.XTGL.attachment.AttachmentButtonN", { isSingle : true, fileTypes : "*.gif;*.pdf;*.jpg;*.doc;*.xls;*.docx;*.xlsx;*.rar;*.zip;*.png;*.rm;*.rmvb;*.avi;*.wmv;*.mp3", scale : ‘medium‘, id : ‘attachmentButton‘, cellCls : ‘labelbutton‘, baseParams : { extParam : ‘AAAAA‘ }, listeners : { uploadsuccess : function(serverData) { if (serverData.success = ‘true‘) { Ext.Ajax.request({ url : ‘/sfjcgl/lzbahjwzhgl/zhgl/getFileName‘, success : function(r) { var data = Ext.decode(r.responseText); if (data.fileName && data.fileName.length && data.fileName.length > 0) { var lxgb = data.fileName[data.fileName.length - 1]; Ext.getCmp(‘FJ‘).show(); Ext.getCmp(‘FJ‘).setValue(lxgb); Ext.getCmp("DeleteFile") .setVisible(true); } }, failure : function(r) { Ext.Msg.alert("提示", "查询失败!"); } }); } else { Ext.Msg.alert("提示", "上传失败!"); } } } }); this.attachmentButton = attachmentButton;
将它单独作为一个form
var form2 = new Ext.form.FormPanel({ baseCls : "", width : "99%", layout : "form", id : "form2", items : [{ baseCls : "", layout : ‘hbox‘, items : [{ xtype : ‘label‘, width : "15%", text : ‘具体内容:‘, name : "具体内容", fieldLabel : "具体内容", labelStyle : "font-size:‘5px‘", style : { textAlign : ‘right‘ } }, { xtype : ‘label‘, html : "<span id=‘DownloadFile‘></span>" }, { layout : ‘hbox‘, xtype : ‘textfield‘, width : 200, id : ‘FJ‘ }, { xtype : ‘button‘, id : "DeleteFile", text : "删除附件", listeners : { "click" : function() { Ext.Ajax.request({ url : "/sfjcgl/lzbahjwzhgl/zhgl/deleteAttachment", params : { recordId : me.PXBID, tableName : ‘SFJC08‘ }, success : function(r) { Ext.getCmp("DeleteFile") .setVisible(false); Ext.getCmp(‘FJ‘).setValue(‘‘); Ext.Msg.alert("提示", "附件删除成功!"); }, failure : function(r) { Ext.Msg.alert("提示", "删除附件失败!"); } }); } } }, attachmentButton] }] }); Ext.getCmp("DeleteFile").setVisible(false); // 隐藏删除按钮
点击保存时
Ext.Ajax.request({ url : ‘/sfjcgl/lzbahjwzhgl/zhgl/savedata?theme=none‘, params : params, success : function(response) { var data = Ext.decode(response.responseText); if (data.success == ‘true‘) { Ext.Msg.alert("提示", "操作成功!"); } else { Ext.Msg.alert("提示", "操作失败!"); } attachmentButton.baseParams.recordID = data.uuid; attachmentButton.baseParams.tableName = "SFJC08"; attachmentButton.baseParams.extParam = "AAAAA"; attachmentButton.Save(); me.up("window").destroy(); me.onPanelSuccessClose(); }, failure : function(response) { Ext.Msg.alert("提示", "操作失败!"); } });
2.在java文件中下载删除附件,取附件名称
/** * 下载附件 */ @Action public void download(){ HttpServletRequest request = ActionContext.getActionContext().getHttpServletRequest(); HttpServletResponse response = ActionContext.getActionContext().getHttpServletResponse(); String fid = request.getParameter("fid"); String downSql = "select FILEPATH,FILENAME from S_ATTACHMENT_FILE where FID = ‘" + fid +"‘"; Map<String, Object> downObj = jdbcOperations.queryForMap(downSql); String path = downObj.get("FILEPATH").toString(); String filename = downObj.get("FILENAME").toString(); File file = new File(path); // 以流的形式下载文件 try { InputStream fis = new BufferedInputStream(new FileInputStream(path)); byte[] buffer = new byte[fis.available()]; fis.read(buffer); fis.close(); // 清空response response.reset(); // 设置response的Header response.addHeader("Content-Disposition", "attachment;filename=" + new String(filename.getBytes("gbk"), "iso-8859-1")); response.addHeader("Content-Length", "" + file.length()); OutputStream toClient = new BufferedOutputStream(response.getOutputStream()); response.setContentType("application/octet-stream"); toClient.write(buffer); toClient.flush(); toClient.close(); } catch (IOException e) { e.printStackTrace(); } } // 取附件名称 @Action public String getFileName() { HttpServletRequest request = ActionContext.getActionContext() .getHttpServletRequest(); HttpSession session = request.getSession(); Map<String, ArrayList<String>> fileNameMap = new HashMap<String, ArrayList<String>>(); ArrayList<Map<String, Object>> fileArray = new ArrayList<Map<String, Object>>(); Object sessionObj = session.getAttribute("uploadList"); if (null != sessionObj) { fileArray = (ArrayList<Map<String, Object>>) sessionObj; ArrayList fileNameArrayList = new ArrayList<String>(); for (Map<String, Object> map : fileArray) { if (null != map.get("filename")) { fileNameArrayList.add((String) map.get("filename")); } } fileNameMap.put("fileName", fileNameArrayList); } return Json.encode(fileNameMap); } @Action public void deleteAttachment() { HttpServletRequest request = ActionContext.getActionContext() .getHttpServletRequest(); String fileID = ""; String recordId = request.getParameter("recordId"); String tableName = request.getParameter("tableName"); String ftype = request.getParameter("ftype"); String querySQL = null; List<Map<String, Object>> list = null; if (null != ftype && !"".equals(ftype)) { querySQL = "select A1.FID from S_ATTACHMENT_RELATION A1 LEFT JOIN S_ATTACHMENT_FILE A2 ON A1.FID = A2.FID WHERE A1.TABLENAME=? AND A1.RECORDID = ? AND A2.FTYPE = ?"; list = jdbcOperations.queryForList(querySQL, tableName, recordId, ftype); } else { querySQL = "select FID from S_ATTACHMENT_RELATION WHERE TABLENAME=? AND RECORDID = ?"; list = jdbcOperations.queryForList(querySQL, tableName, recordId); } if (list.size() > 0) { fileID = list.get(0).get("FID").toString(); } /** * 删除保存的上传文件 * * 功能待实现 * */ if (fileID != null && !"".equals(fileID) && !"null".equals("fileID")) { /** * 删除文件记录表数据 */ String deleteSql = "DELETE FROM S_ATTACHMENT_FILE WHERE FID = ? "; jdbcOperations.update(deleteSql, fileID); /** * 删除数据文件关联表 */ deleteSql = "DELETE FROM S_ATTACHMENT_RELATION WHERE FID = ? "; jdbcOperations.update(deleteSql, fileID); } }
