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：

importorg.apache.poi.xwpf.usermodel.XWPFDocument;

importjava.io.IOException;

importjava.io.InputStream;

importorg.apache.poi.openxml4j.opc.OPCPackage;

importorg.apache.poi.xwpf.usermodel.XWPFDocument;

importorg.apache.poi.xwpf.usermodel.XWPFParagraph;

importorg.apache.xmlbeans.XmlException;

importorg.apache.xmlbeans.XmlToken;

importorg.openxmlformats.schemas.drawingml.x2006.main.CTNonVisualDrawingProps;

importorg.openxmlformats.schemas.drawingml.x2006.main.CTPositiveSize2D;

importorg.openxmlformats.schemas.drawingml.x2006.wordprocessingDrawing.CTInline;

/**

*@authordongqianggao

*@version2017-12-18 18:08

*/

public classCustomXWPFDocument extendsXWPFDocument {

publicCustomXWPFDocument(InputStream in) throwsIOException {

super(in);

}

/**

*

*/

publicCustomXWPFDocument() {

super();

//TODO Auto-generated constructor stub

}

/**

*@parampkg

*@throwsIOException

*/

publicCustomXWPFDocument(OPCPackage pkg) throwsIOException {

super(pkg);

//TODO Auto-generated constructor stub

} // picAttch图片后面追加的字符串 可以是空格

public voidcreatePicture(XWPFParagraph paragraph,intid, intwidth, intheight,String picAttch) {

final intEMU = 9525;

width *= EMU;

height *= EMU;

String blipId = getAllPictures().get(id).getPackageRelationship()

.getId();

CTInline inline = paragraph.createRun().getCTR()

.addNewDrawing().addNewInline();

paragraph.createRun().setText(picAttch);

String picXml = ""

+ ""

+ " "

+ " "

+ " "+ "

+ id

+ "\"name=\"Generated\"/>"

+ " "

+ "

"

+ " "

+ "

+ blipId

+ "\"xmlns:r=\"http://schemas.openxmlformats.org/officeDocument/2006/relationships\"/>"

+ " "

+ " "

+ " "

+ " "

+ " "

+ " "

+ " "

+ "

+ width

+ "\"cy=\""

+ height

+ "\"/>"

+ " "

+ " "+ "";

// CTGraphicalObjectData graphicData =

inline.addNewGraphic().addNewGraphicData();

XmlToken xmlToken = null;

try{

xmlToken = XmlToken.Factory.parse(picXml);

} catch(XmlException xe) {

xe.printStackTrace();

}

inline.set(xmlToken);

// graphicData.set(xmlToken);

inline.setDistT(0);

inline.setDistB(0);

inline.setDistL(0);

inline.setDistR(0);

CTPositiveSize2D extent = inline.addNewExtent();

extent.setCx(width);

extent.setCy(height);

CTNonVisualDrawingProps docPr = inline.addNewDocPr();

docPr.setId(id);

docPr.setName("图片"+ id);

docPr.setDescr("");

}

}

实际使用方法如下：

public voidexpWord(OrderRefund orderRefund,HttpServletRequest request,HttpServletResponse response){

try{

CustomXWPFDocument doc = newCustomXWPFDocument(); //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(newFileInputStream(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

intres = 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();

}

}
