触发场景描述
一个Excel文件含有多个工作簿，设置部分工作簿隐藏之后，通过文件上传EasyExcel读取解析该文件出现OOM [Uploading 日报模板-0304的副本2.xlsx…]()触发Bug的代码
if (file == null) {
return null;
}
ExcelReader excelReader = null;
SourceJoinDataListener sourceJoinDataListener = new SourceJoinDataListener(Constant.FILE_SOURCE_ID.toString(), preview, append, tableNameIdMap);
try (InputStream inputStream = file.getInputStream()) {
excelReader = EasyExcelFactory.read(inputStream , sourceJoinDataListener).build();
List<ReadSheet> readSheets = excelReader.excelExecutor().sheetList();
checkDuplicateSheetNameAndLength(readSheets);
excelReader.read(readSheets);
} catch (Exception e) {
if (e instanceof BusinessException) {
throw e;
}
Throwable cause = e.getCause();
if (cause instanceof BusinessException) {
String message = e.getMessage();
if (!StringUtils.isNullOrEmpty(message)) {
String[] split = message.split(":");
String errorMessage = split.length > 1 ? split[1].trim() : message;
ErrorCodeEnum.CUSTOMIZE_BUSINESS_EXCEPTION.throwBizException(errorMessage);
}
} else {
e.printStackTrace();
log.error("解析excel失败", e);
ErrorCodeEnum.PARSE_EXCEL_ERROR.throwBizException();
}
} finally {
if (excelReader != null) {
// 这里千万别忘记关闭，读的时候会创建临时文件，到时磁盘会崩的
excelReader.finish();
}
}提示的异常或者没有达到的效果
