问题 SetCellType(HSSFCELL.CELL_TYPE_NUMERIC) is not working in apache poi. Anyone have used this feature of POI in JAVA? When I created XLS file using POI and cell contains integer value and I set cell type as numeric at that time that cell reflects some other integer value. Example: Using JAVA program and poi utility, I am putting in Cell A1 value "5" . Now this cell contains Integer value but by default cell type is CELL_TYPE_STRING . So this cell gives me error and asked me to convert this cell

问题 I have the problem with the following code: XWPFTable table = <get table somehow>; CTRow firstRow = table.getRow(0).getCtRow(); for (int i = 0; i < data.getRowCount(); i++) { CTRow ctRow = (CTRow) firstRow.copy(); XWPFTableRow row = new XWPFTableRow(ctRow, table); XWPFRun[] cellRuns = row.getTableCells() .stream() .map(c -> c.getParagraphs().get(0)) .map(p -> p.getRuns().isEmpty() ? p.createRun() : p.getRuns().get(0)) .toArray(XWPFRun[]::new); for (int j = 0; j < cellRuns.length; j++) {

问题 I've got a piece of code which is erroring when I attempt to get the Styles Table for an Excel file, using apache POIs XSSFReader. All I do, involving the file, is shown below: XSSFReader reader = new XSSFReader(OPCPackage.open(excelFile.getPath(), PackageAccess.READ)); StylesTable table = reader.getStylesTable(); I get the following error: Caused by: java.io.IOException: Zip bomb detected! The file would exceed certain limits which usually indicate that the file is used to inflate memory

问题 I am new to jasper . My project used jasper to create an excel template that has only column names (eg : Name , Age , Department , Location) which uses jrxml for fonts and alignment. [basically we used the for showing the column names] User can download the template and they can enter the values they want. Now in order to avoid user enter the details manually by entering values , I would like to give dropdowns in the template with some hard coded values . For example for the field 'Location'

问题 I am writing a java program in which I have to take data from XML file and put it into excel file. While doing this I have to create row headers and add data accordingly.

问题 I have spent countless hours trying to find a solution to this. I have tried Apache POI, JExcel and JXLS but no where have I found code to successfully read checkbox (form control) values. If anyone has found a working solution then it would be great if you could share it here. Thanks! UPDATE I have written code that reads the checkbox but it cannot determine whether it is checked or not. import java.io.File; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io

问题 I'm trying to read data from excel using POI. How can I check if that is an empty cell? I don't know what is missing I think this should be working: java.util.Iterator<Row> rows = worksheet.rowIterator(); HSSFRow row = (HSSFRow) rows.next(); HSSFCell cellF1 = (HSSFCell) row.getCell(5); if(cellF1.getCellType() == HSSFCell.CELL_TYPE_BLANK) { String val = ""; } I got error in if statement (null pointer), but only if I use this I can check that: while (rows.hasNext()) { HSSFRow row = (HSSFRow)

问题 I am currently using HSSFColor/HSSFPalette and XSSFColor to set the Existing/Custom Colors. Implementation is as follows : for e.g. font.setColor(HSSFColor.WHITE.index); for HSSF or cs.setFillForegroundColor(xssfColor); for XSSF I want to pass parameters in both the above cases for "Hexadecimal Color Codes". Like : for HSSF: font.setColor()/font.setColor(getShortIndexFromHexColorCodes()) for XSSF: cs.setFillForegroundColor(); Is there any way out to do the above thing, where I can pass

问题 I am trying to get the "last saved by" attribute from MS Office 2013 file(docx, xlsx, pptx ...). I am using Apache POI, but I can get only the Author of the file with the following code: OPCPackage pkg = OPCPackage.open(file); POIXMLProperties props = new POIXMLProperties(pkg); props.getCoreProperties().getCreator(); Is there a way to get "last saved by" attribute? 回答1: Lookin at the Apache POI OOXML Properties Extractor as a good source of inspiration for this sort of problem, we see what
