java 导出word_Java使用word模板导出word

1.创建一个空的springboot工程，引入jar包

org.apache.poi

poi-ooxml

3.17

org.apache.poi

2.工具类一

import java.io.InputStream;

}

public void createPicture(String blipId,int id, int width, int height, XWPFParagraph paragraph)

{

final int EMU = 9525;

//给段落插入图片

CTInline inline = paragraph.createRun().getCTR().addNewDrawing().addNewInline();

String picXml = "" +
