java 生成word

public class RTFCreate {

public static void main(String[] args) throws MalformedURLException,
   IOException {
RTFCreate rtfCreate = new RTFCreate();
try {    String bodyText="abc";
   //byte[] b= null;
   //rtfCreate.createRTF(bodyText,"WebRoot/images/yjg.png");
// rtfCreate.createRTF(bodyText,b);
// } catch (FileNotFoundException e) {
/  
//    e.printStackTrace();
//   } catch (DocumentException e) {
//  
//    e.printStackTrace();
//   }
// }

public String createRTF(String bodyText, byte[] image) throws DocumentException, BadElementException,
    MalformedURLException, IOException {
  
   String filePath = "c:/testW.rtf";
   Document document = new Document(PageSize.A4);
   // document.addTitle("Title");
   // document.addHeader("header","Header");

//生成html格式文件
//   HtmlWriter.getInstance(document, new FileOutputStream("C:/testW.html"));

//生成rtf格式文件doc文件
   RtfWriter2.getInstance(document, new FileOutputStream("C:/testW.rtf"));

//生成pdf格式文件
//   PdfWriter.getInstance(document, new FileOutputStream("C:/testW.pdf"));


////生成xml格式文件

//   XmlWriter.getInstance(document, new FileOutputStream("C:/testW.xml"));
   document.open();
   // add a word
   document.add(new Paragraph(bodyText));
   // add a table
   Table table = new Table(3);
   table.setBorderWidth(1);
   table.setBorderColor(new Color(0, 0, 255));
   table.setPadding(5);
   table.setSpacing(5);
   Cell cell = new Cell("header");
cell.setHeader(true);
   cell.setColspan(3);
   table.addCell(cell);
   table.endHeaders();
cell = new Cell("example cell with colspan 1 and rowspan 2");
   cell.setRowspan(2);
   cell.setBorderColor(new Color(255, 0, 0));
   table.addCell(cell);
   table.addCell("1.1");
   table.addCell("2.1");
   table.addCell("1.2");
   table.addCell("2.2");
   table.addCell("cell test1");
   cell = new Cell("big cell");
   cell.setRowspan(2);
   cell.setColspan(2);
   table.addCell(cell);
table.addCell("cell test2");
document.add(table);

//这里可以是图片路径，也可以把图片读为是byte[] 类型传进来，我这里用的是byte 因为我的图片从数据表取出
   //Image png = Image.getInstance(imageUrl);
   Image img = Image.getInstance(image);
   document.add(img);
   document.close();

//返回生成word文档的路径，为了在Action 中读出此word文件
   return filePath;
  
}

Action 方法中读取word文件，可以读取图片，部分代码

String bodyText = null;
   if (clsb != null) {
    bodyText = clsb.getBodyText();
   }

if(bodyText !=null){
    RTFCreate rtfCreate = new RTFCreate();
    try{
     //TODO word letter form 
     CamDoc cdoc = new CamDoc();
     cdoc = camDocControl.findByRecordID(3);
     byte[] cimg = cdoc.getDocObject();
     request.setAttribute("cimg", cimg);
     String body = TestHTMLParser.testHtml(bodyText);//使用htmlparser来解析html中的文本 
    
     String filePath = rtfCreate.createRTF(body, cimg);
     FileInputStream fis = new FileInputStream(filePath);
     // 1 k = 1024 byte , 1 m = 1024 k = 1048576 byte
     // 10000000 byte = 9.5 m
     byte[] bytes = new byte[10000000];
     while (fis.read(bytes) != -1) // 将文件读入byte数组
     {

     }
     
      response.reset();
      response.setContentType("application/rtf;charset=UTF-8");
      response.setContentLength(bytes.length);
      response.setHeader("Content-disposition",
        "attachment; filename=bankAuthForm.doc");
  
      ServletOutputStream ouputStream = response.getOutputStream();
      ouputStream.write(bytes, 0, bytes.length);
      ouputStream.flush();
      ouputStream.close();

//这段是提取word 文件中的文本
//     String st = null;
//          DefaultStyledDocument styledDoc = new DefaultStyledDocument(); 
//          InputStream is = new FileInputStream(new File("c:/testW.rtf"));
//             new RTFEditorKit().read(is, styledDoc, 0);
//             st = styledDoc.getText(0, styledDoc.getLength());
//             System.out.println("---rtf content>>>"+st);
             //   String(styledDoc.getText(0, styledDoc.getLength()).getBytes("UTF-8"));
    }catch(Exception e){
     e.printStackTrace();
    }
   }
   return null;

}

jsp 直接頁面直接生成word 文檔來下載保存，這個基本可以滿足了。

Action ：中的方法

public ActionForward downloadWord(ActionMapping mapping, ActionForm form,
    HttpServletRequest request, HttpServletResponse response) throws Exception {
   return mapping.findForward("printWord");}

轉到這個生成word 文檔的頁面。

在此JSP 頁面中加上：<%@ page contentType="application/msword; charset=UTF-8" %>
<%
response.setHeader("Content-Disposition", "attachment;filename=application.doc");
%>這兩句后即可以下載了。
