升级4.x版本注意事项

因POI 4.x与5.x版本存在部分不兼容情况,升级MyExcel为4.x(POI 5.x)时,需要注意以下事项:

  1. POI版本必须为5.x
  2. 排除掉poi-ooxml-schemas依赖(POI 5.x以poi-ooxml-full作为代替)
  3. commons-io版本为2.11.0

Velocity模板引擎注意事项

自MyExcel 4.0.2版本开始,Velocity依赖修改如下:

<dependency>
    <groupId>org.apache.velocity</groupId>
    <artifactId>velocity-engine-core</artifactId>
    <version>2.3</version>
</dependency>

如仍然使用旧依赖,可能会有编码错乱问题。
