这是做Excel导出的时候 发生异常
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>easyexcel</artifactId>
<version>3.3.2</version>
</dependency>3. 解决
ExcelWriter excelWriter = EasyExcel.write(response.getOutputStream(), ExcelVo.class).includeColumnFieldNames(eventExportDTO.getIncludeColumnFieldNames()).registerWriteHandler(getCellStyleStrategy()).build()
发现没有关闭流导致的
excelWriter.finish();
