我想使用 primefaces 4.0 或 primefaces 扩展导出器在一个 Excel 文件中导出多个数据表,每个数据表都在单独的工作表中。这可以做到吗?

使用jxl框架处理 Excel 文件。我认为它仍然是最好的选择之一。
一个例子:
public void createExcelReport(OutputStream stream) {
WritableWorkbook workbook = null;
try {
Workbook template = Workbook.getWorkbook(new File(getClass().getResource("/report/report_template.xls").getFile()));
workbook = Workbook.createWorkbook(stream, template);
WritableSheet sheet = workbook.getSheet(0);
int idx = START_ROW_IDX;
for (SomePojo pojo : pojoService.getPojos()) {
writePojoToRow(pojo);
idx++;
}
if (idx == START_ROW_IDX) {
addNoErrorSheet(sheet);
}
workbook.write();
} catch (Exception e) {
log.error("There was a problem here.", e);
throw new RuntimeException("Excel file creation did not work because of this Exception: ", e);
} finally {
if (workbook != null) {
try {
workbook.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
