엑셀 다운로드 중 10만 column의 엑셀 데이터를 다운 받으려니 엄청난 에러가 떴다. 사실 이 문제는 처음부터 예상한 문제였다.
코드 리뷰 때 팀원이 언급해준 내용이었고 수정하는 과정에서 실험해 본 것이다.
그런데 이렇게 리뷰하는 팀 활동이 처음이라 그런지 내 코드의 문제점을 찾아주셔서 너무 감사했고, 기록을 남기고 싶어서 글을 작성한다.
문제 해결
private <T> void createDataRows(
Workbook workbook,
Sheet sheet,
List<ExcelField> fields,
List<T> dataList,
ExcelDataMapper<T> mapper
) {
for (int rowIndex = 0; rowIndex < dataList.size(); rowIndex++) {
Row dataRow = sheet.createRow(rowIndex + 1);
T data = dataList.get(rowIndex);
Object[] rowData = mapper.extractRowData(data);
createDataColsByRow(workbook, fields, rowData, dataRow);
}
}
private void createDataColsByRow(Workbook workbook, List<ExcelField> fields, Object[] rowData, Row dataRow) {
int colCount = Math.min(fields.size(), rowData.length);
for (int colIndex = 0; colIndex < colCount; colIndex++) {
ExcelField field = fields.get(colIndex);
Cell cell = dataRow.createCell(colIndex);
setCellValue(cell, rowData[colIndex]);
CellStyle dataStyle = renderDataStyle(workbook, field.getFormat());
cell.setCellStyle(dataStyle);
}
}
private CellStyle renderDataStyle(Workbook workbook, FieldFormat fieldFormat) {
CellStyle style = workbook.createCellStyle();
DataFormat dataFormat = workbook.createDataFormat();
String pattern = fieldFormat.getPattern();
short format = dataFormat.getFormat(pattern);
style.setDataFormat(format);
return style;
}기존의 코드인데, 해결법은 간단했다. 팀원이 가르쳐주셨기 때문이다.
감사합니다 윤정님 ㅠㅠ
private List<CellStyle> createColumnStyles(List<ExcelField> fields, Workbook workbook) {
return fields.stream()
.map(field -> renderDataStyle(workbook, field.getFormat()))
.toList();
}그래서 나는 미리 Field 정보들을 추출하고 재사용하는 방식을 적용했다.
private void createDataColsByRow(
List<ExcelField> fields,
Object[] rowData,
Row dataRow,
List<CellStyle> columnStyles
) {
int colCount = Math.min(fields.size(), rowData.length);
for (int colIndex = 0; colIndex < colCount; colIndex++) {
Cell cell = dataRow.createCell(colIndex);
setCellValue(cell, rowData[colIndex]);
cell.setCellStyle(columnStyles.get(colIndex));
}
}그리고 cell 별 스타일을 가져와서 적용한다.
결과는 잘 다운로드 된다. 데이터 스타일도 잘 적용됐다.
다만 아쉬운 문제점이 발생했다.
@GetMapping("/down")
public void test(HttpServletResponse response, @RequestParam int col) {
List<TestDto> data = testDtos.stream().limit(col).toList();
long start = System.currentTimeMillis();
excelDownloader.downloadAsStream(data, response);
long end = System.currentTimeMillis();
System.out.println("Time: " + (end - start) / 1000.0 + "s");
}
10만개 데이터를 다운로드 받는데 31초나 걸렸따..
try (SXSSFWorkbook workbook = new SXSSFWorkbook(WINDOW_SIZE)) {
workbook.setCompressTempFiles(true);
SXSSFSheet sheet = workbook.createSheet(mapper.getSheetName());
//sheet.trackAllColumnsForAutoSizing();
List<ExcelField> fields = mapper.getFields();
createHeaderRow(workbook, sheet, fields);
List<CellStyle> cellStyles = createColumnStyles(fields, workbook);
createDataRows(sheet, fields, dataList, mapper, cellStyles);
//autoSizeColumns(sheet, fields.size());
workbook.write(outputStream);
outputStream.flush();
}스트림에서는 AutoSize를 추적해야되는데 이게 생각보다 시간을 너무 많이 잡아먹었다.
주석처리 후 10만개의 데이터를 엑셀 파일로 추출하는데 1초도 안걸린다.
아쉬운 부분은 AutoSize까지 적용해주고 싶은데, 어차피 관리자분들께서는 엑셀 매크로를 따로 적용해두실 것 같으니 정보만 있어도 될 것 같기도..
마치며
팀원과의 리뷰 덕분에, 내가 예상하지 못한 문제점을 해결할 수 있었다.
팀 리뷰의 중요성을 깨닫고 Apache POI의 CellStyle 개수 제한에 대해서도 알 수 있었다.
if (이런 시나리오는 어떨까?) then(테스트로 검증하고 해결) else(다음 시나리오 고민)
