问题记录：Linux环境EasyExcel的doWrite方法报错问题

2023-04-19 18:37| 来源: 网络整理| 查看: 265

背景

使用easyexcel进行数据导出时报错，服务是使用Dockerfile打包镜像然后Docker启动服务。在测试到数据导出功能也就是doWrite方法报错，且不同环境下可以正常导出，猜想：由于Linux环境导致。

Dockerfile

FROM openjdk:8-jdk-alpine ADD source.jar target.jar ENV TZ Asia/Shanghai CMD java -jar target.jar

报错方法

ExcelWriterBuilder.doWrite(excelHeads);

错误堆栈部分代码

Docker新增一段代码下载

RUN apk add --update font-adobe-100dpi ttf-dejavu fontconfig
