Ich versuche ResultSet in Excel (* .xlsx) Tabelle mit Apache Poi zu schreiben.ResultSet in Excel (* .xlsx) Tabelle mit Apache POI
Ungültige Tabellenobjekt Fehler in Office Excel
Doch obwohl es die Excel-Datei ohne Fehler schreibt, wenn ich versuche, es zu öffnen in Office Excel 2013, zeigt es einen Fehler und entfernt das Tabellenobjekt um nur eine Datenansicht zu geben.
Hier ist der grobe Beispielcode using this example:
public static void writeExcel(ResultSet rs, int sqliteRowCount, String dir) {
System.out.println("Writing Excel(*.xlsx) File...");
XSSFWorkbook workbook = null;
try {
if (rs != null) {
// Get ResultSet MetaData
ResultSetMetaData rsmd = rs.getMetaData();
// Number of columns
int numColumns = rsmd.getColumnCount();
// Number of rows
// + 1 for headers
int numRows = sqliteRowCount + 1;
workbook = new XSSFWorkbook();
// Create Excel Table
XSSFSheet sheet = workbook.createSheet("Text");
XSSFTable table = sheet.createTable();
table.setDisplayName("Test");
CTTable cttable;
cttable = table.getCTTable();
// Style configurations
CTTableStyleInfo style = cttable.addNewTableStyleInfo();
style.setName("TableStyleMedium16");
style.setShowColumnStripes(false);
style.setShowRowStripes(true);
// Set Table Span Area
AreaReference reference = new AreaReference(new CellReference(0, 0), new CellReference(numRows - 1, numColumns - 1));
cttable.setRef(reference.formatAsString());
cttable.setId(1);
cttable.setName("Test");
cttable.setDisplayName("Test");
cttable.setTotalsRowCount(numRows);
cttable.setTotalsRowShown(false);
// Create Columns
CTTableColumns columns = cttable.addNewTableColumns();
columns.setCount(numColumns);
// Create Column, Row, Cell Objects
CTTableColumn column;
XSSFRow row;
// Add Header and Columns
XSSFRow headerRow = sheet.createRow(0);
for (int i = 0; i < numColumns; i++) {
column = columns.addNewTableColumn();
column.setName("Column" + (i + 1));
column.setId(i + 1);
headerRow.createCell(i).setCellValue(rsmd.getColumnLabel(i + 1));
}
// Write each row from ResultSet
int rowNumber = 1;
while (rs.next()) {
row = sheet.createRow(rowNumber);
for (int y = 0; y < numColumns; y++) {
row.createCell(y).setCellValue(rs.getString(y + 1));
}
rowNumber++;
}
// Set AutoFilter
CTAutoFilter fltr = CTAutoFilter.Factory.newInstance();
fltr.setRef((new AreaReference(new CellReference(0, 0), new CellReference(numRows - 1, numColumns - 1))).formatAsString());
cttable.setAutoFilter(fltr);
// sheet.setAutoFilter(CellRangeAddress.valueOf((new AreaReference(new CellReference(0, 0), new CellReference(numRows - 1, numColumns - 1))).formatAsString()));
// Freeze Pan
sheet.createFreezePane(0, 1, 0, 2);
}
} catch (SQLException ex) {
System.out.println("SQL Error while writing Excel file!");
} finally {
try {
// Let's write the excel file now
if (workbook != null) {
String excelDir = dir + File.separator + "workbook.xlsx";
try (final FileOutputStream out = new FileOutputStream(excelDir)) {
workbook.write(out);
}
}
} catch (IOException ex) {
System.out.println("IO Error while writing Excel summary file!");
}
}
}
Ich weiß, etwas falsch mit meinem Code, aber kann es nicht herausgefunden. Irgendeine Idee, warum das passiert, wo wäre möglicher Fehler in meinem Code.
Update 1:
Tabelle XML-Datei im Archiv Excel wenn POI
<?xml version="1.0" encoding="UTF-8"?>
<table displayName="Test" ref="A1:B881" id="1" name="Test" totalsRowCount="881" xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main" totalsRowShown="0"><autoFilter ref="A1:B881"/><tableColumns count="2"><tableColumn name="ID" id="1"/><tableColumn name="Name" id="2"/><tableStyleInfo name="TableStyleMedium2" showColumnStripes="true" showRowStripes="true"/></table>
in Excel-Archiv
Tabelle XML-Datei mit Apache erstellt, wenn die Tabelle
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<table xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main" id="1" name="Table1" displayName="Table1" ref="A1:B881" totalsRowShown="0"><autoFilter ref="A1:B881"/><tableColumns count="2"><tableColumn id="1" name="ID"/><tableColumn id="2" name="Name"/></tableColumns><tableStyleInfo name="TableStyleLight9" showFirstColumn="0" showLastColumn="0" showRowStripes="1" showColumnStripes="0"/></table>
Zusätzlich manuell erstellt Wenn ich das Excel-Archiv öffne, hat es keinen Themenordner in dem von Apache POI erstellten Ordner, aber er ist in dem einen crea vorhanden manuell in Office Excel. Seltsam.

Haben Sie sichergestellt, dass Sie die neueste Version von Apache POI verwenden? (3.11 Beta 2 zum Schreiben) – Gagravarr
@Gagravarr: ja ich benutze genau die gleiche Version. – Indigo
Hmm, nervtötend ... Ist Apache POI in der Lage, die erzeugte Datei ohne Fehler zu lesen? Kann es den Tisch sehen? Und wie wäre es mit Open Office - toleriert das die Datei + sehen Sie die Tabelle, oder verbindet es sich mit Excel bei beschweren? – Gagravarr
