EasyExcel读取多sheet excel异常
场景
使用Spring Boot集成EasyExcel进行导入excel多sheet,执行异常
代码
file是MultipartFile,入参,主要处理流程如下
InputStream is = file.getInputStream();
EasyExcel.read(is, SysDict.class, new SysDictReadListener(sysDictMapper, 0L))
.sheet(0, "目录")
.doRead();
List<SysDict> list = sysDictMapper.selectByDictClass1();
for (int i = 0; i < list.size(); i++) {
SysDict sysDict = list.get(i);
// sheet序号
Integer sheetNo = i + 1;
String sheetName = sysDict.getDictName();
EasyExcel.read(is, SysDict.class, new SysDictReadListener(sysDictMapper, sysDict.getDictId()))
.sheet(sheetNo, sheetName)
.doRead();
}
问题描述
异常:com.alibaba.excel.exception.ExcelCommonException: Convert excel format exception.You can try specifying the ‘excelType’ yourself
按照描述,缺少excelType参数,补充后,代码大概如下:
EasyExcel.read(is, SysDict.class, new SysDictReadListener(sysDictMapper, 0L))
.excelType(ExcelTypeEnum.XLSX)
.sheet(0, "目录")
.doRead();
异常:com.alibaba.excel.exception.ExcelAnalysisException: Can not create temporary file!文章来源:https://www.toymoban.com/news/detail-605033.html
方案
按照上述补充excelType,并不能解决问题,经过检索,发现问题是多sheet会重复读取流对象,而一个流对象只能读取一次,重复使用,会导致上述异常,解决代码如下:文章来源地址https://www.toymoban.com/news/detail-605033.html
// 获取MultipartFile的流
is = file.getInputStream();
// 读取第一个sheet
EasyExcel.read(..);
// 读取剩余的sheet
is = file.getInputStream();
EasyExcel.read(..);
