触发场景描述 resin服务器环境下 触发Bug的代码
List<DemoData> result = data();
EasyExcel.write(response.getOutputStream(), DemoData.class).sheet("sheet1").doWrite(result);提示的异常或者没有达到的效果 getWriter() can't be called after getOutputStream()
请提供详细异常 和详细代码
代码应该影响不大，问题主要是针对某些容器类型的，本地jetty可以运行，线上使用的resin（已验证），可能welogic也会报错（未验证） 项目框架 SSM 版本依赖： `
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>3.17</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>3.17</version>
</dependency>`
涉及功能，web导出
代码
@Get("/ot/export/pa") public void paymanageExport(@Param("a") String a, @Param("b") String b, HttpServletRequest request, HttpServletResponse response) throws Exception { List<DataRow> result = Lists.newArrayList(); ImmutablePair<Boolean, Object> ret = homeDataService.getTableData(a, b); String fileName = URLEncoder.encode(homeDataService.fileNameGenerator(a, b), "UTF-8"); response.setContentType("application/vnd.ms-excel"); response.setCharacterEncoding("utf-8"); //URLEncoder.encode防止中文乱码 String fileName = URLEncoder.encode(homeDataService.fileNameGenerator(a, b), "UTF-8"); response.setHeader("Content-disposition", "attachment;filename=" + fileName + ".xlsx"); EasyExcel.write(response.getOutputStream(), DataRow.class).sheet("sheet1").doWrite(result); }
实体类
@Data public class DataRow implements Bean { @ExcelProperty("序号") private int rank; @ExcelProperty("编码") private String code; @ExcelProperty("名称") private String name; }
请提供详细异常

是不是 框架不一样 你尝试 设置参数 autoclosestream 为false 应该就行了
