编写相关工具类

可以自己写或用别人写好的轮子。Excel一般会比较简单实现，我在熟悉POI相关编写时先找了一个不错的开源代码，强烈推荐直接使用或作为学习参照:

需求:

  1. 根据需求编写对应实体类或存储结构等(省略)。

Word

需求:

通过 https://github.com/hyberbin/J-Excel 的开源工具代码来实现
或自编Word工具类实现

  1. 编写实体类和控制层，和Excel导出大体相同。

  2. 服务层

Word插入图片时，调用POI函数addPicture导致生成的Word无法打开。

public XWPFPicture addPicture(InputStream pictureData, int pictureType, String filename, int width, int height) throws InvalidFormatException, IOException

首先定位BUG产生原因应该是XWPFRun成员方法生成图片后无法在新版Word打开(xml问题?)

参考：https://blog.csdn.net/Alice_qixin/article/details/71730346

通过自实现Document继承XWPFDocument，实现插入图片方法createPic。

用自定义的Document代替XWPFDocument，并在插入图片时参考写入以下代码

CTInline ctInline = tempRun.getCTR().addNewDrawing().addNewInline();//设置段落行
String id = document.addPictureData(getPicStream(path), picType);
int idPic = document.getAllPackagePictures().size()+1;
document.createPic(id,idPic,width,height,ctInline);//添加图片
