我想寫ResultSet轉Excel(* .xlsx)表使用Apache Poi。在Office ExcelResultSet轉Excel(* .xlsx)表使用Apache POI
無效的表對象錯誤
然而,即使它寫入Excel文件沒有任何錯誤,當我嘗試在Office Excel 2013中打開它,它顯示了一個錯誤,並刪除表格對象只給出純數據視圖。
這裏是粗略的示例代碼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!");
}
}
}
我知道什麼是錯我的代碼,但不能弄明白。 任何想法,爲什麼會發生這種情況,哪裏會出現我的代碼中的潛在錯誤。
更新1:在Excel檔案,如果表手動
<?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>
創建另外使用Apache 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>
表XML文件在Excel檔案,如果創建
表XML文件,如果我打開Excel歸檔文件,它沒有由Apache POI創建的主題文件夾,但它存在於一個創建中在Office Excel中手動。奇怪。

您是否確定自己使用的是最新版本的Apache POI? (截至撰寫時爲3.11測試版) – Gagravarr 2014-08-29 16:27:59
@Gagravarr:是的,我使用的是完全相同的版本。 – Indigo 2014-08-29 16:59:16
嗯,討厭... Apache POI能夠讀取沒有錯誤生成的文件嗎?它能看到桌子嗎?那麼Open Office怎麼樣?它是否容忍文件+查看錶格,或者是否在Excel中投訴? – Gagravarr 2014-08-29 17:04:41
