POI导出简单的带有图片的Word文档
由于导出的文档中需要插入图片，因此需要新建类来处理由于插入图片引进的错误即“导出的word文档在打开时会报内容出现错误，无法打开文件”
新建处理类为：
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import java.io.IOException;
import java.io.InputStream;
import org.apache.poi.openxml4j.opc.OPCPackage;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.xmlbeans.XmlException;
import org.apache.xmlbeans.XmlToken;
import org.openxmlformats.schemas.drawingml.x2006.main.CTNonVisualDrawingProps;
import org.openxmlformats.schemas.drawingml.x2006.main.CTPositiveSize2D;
import org.openxmlformats.schemas.drawingml.x2006.wordprocessingDrawing.CTInline;

String picXml = “”

}
实际使用方法如下：
public void expWord(OrderRefund orderRefund,HttpServletRequest request,HttpServletResponse response){
try{
CustomXWPFDocument doc = new CustomXWPFDocument(); //创建文档实体
XWPFParagraph title = doc.createParagraph(); //创建一个段落
title.setAlignment(ParagraphAlignment.CENTER); //设置段落的位置
XWPFRun r1 = title.createRun(); //设置相同样式的文本
r1.setBold(true); //设置字体是否加粗
r1.setFontFamily(“宋体“); //设置字体
r1.setText(“退费审批表“); //添加文字内容
r1.setFontSize(16); //设置字体大小
//插入图片文件，同样需要新建一个段落实体
XWPFParagraph pic = doc.createParagraph();
pic1.setAlignment(ParagraphAlignment.CENTER);
doc.addPictureData(new FileInputStream(request.getSession().getServletContext().getRealPath(“/”)+“/upload/refund/qmw.png”),XWPFDocument.PICTURE_TYPE_PNG);
doc.createPicture(pic,doc.getAllPictures().size()-1, 97, 47,” “);
//判断添加的图片的类型
int res = XWPFDocument.PICTURE_TYPE_PICT;
if(picType != null){
if(picType.equalsIgnoreCase(“png”)){
res = XWPFDocument.PICTURE_TYPE_PNG;
}else if(picType.equalsIgnoreCase(“gif”)) {
res = XWPFDocument.PICTURE_TYPE_GIF;
}else if(picType.equalsIgnoreCase(“jpg”) || picType.equalsIgnoreCase(“jpeg”)){
res = XWPFDocument.PICTURE_TYPE_JPEG;
}
}
//通过respons输出提示框下载文件，要注意的是如果文件名称中有文字，需要对文件名称进行URLEncoder编码
String fileName = “退费审批表——”+orderRefund.getProInfo().getProName();
OutputStream out=response.getOutputStream();
response.setHeader(“Content-Type”,“application/ms-winword”);
response.addHeader(“Content-Disposition”,“attachment;filename=\”“+ URLEncoder.encode(fileName,“UTF-8”)+ “.docx\”“);
response.setContentType(“application/octet-stream”);
response.setCharacterEncoding(“UTF-8”);
doc.write(out);
out.close();
}catch(Exception e){
e.printStackTrace();
}
}
