使用itext操作pdf导出（springmvc框架）

  @RequestMapping(value = "/exportPdf.do", method = RequestMethod.POST)
    public void exportPdf(HttpServletRequest request, HttpServletResponse response) throws DocumentException, IOException {
    	response.setCharacterEncoding("UTF-8");
    	request.setCharacterEncoding("UTF-8");
		String fileName="";
		//PdfWriter pdfWriter=null;
		//字体格式设置
		BaseFont bfChinese=BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);
		Font FontChinese=new Font(bfChinese,10,Font.NORMAL);
		//1创建document对象
		Rectangle rectPageSize=new Rectangle(PageSize.A4);
		//下面代码设置页面横置
		//创建document对象并指定边框
		Document doc=new Document(rectPageSize,80,80,80,80);
		Document document=new Document();
		fileName ="平台更新公告详情"+DateUtil.generateStandardDateTimeFormat2(new Date()) + ".pdf";
		//response.setContentType("application/pdf");
		
		//fileName=new String(fileName.getBytes(),"UTF-8");
		//response.setHeader("Content-disposition","attachment; FileName="+fileName);
        ByteArrayOutputStream bos= new ByteArrayOutputStream();
        //OutputStream out=response.getOutputStream();
		//buffer.writeTo(out);
        PdfWriter.getInstance(document,bos);
		//buffer.close();
		//out.flush();
		document.open();
		//创建表格
		PdfPTable table = new PdfPTable(3);
		table.addCell(new Paragraph("内容",FontChinese));
		table.addCell(new Paragraph("时间",FontChinese));
		table.addCell(new Paragraph("创建人",FontChinese));
	//	table.addCell(new Paragraph("告警次数",FontChinese));
	//	table.addCell(new Paragraph("合格率",FontChinese));
		
		////////
		 Notice notice =new Notice();
	 		List<Notice> hjllist=noticeService.queryPage(notice);
	 		SimpleDateFormat datafDateFormat=new SimpleDateFormat("yyyy-MM-dd");
	 		
	 		//////
		for(int i = 0 ; i < hjllist.size();i++){
			table.addCell(new Paragraph(hjllist.get(i).getNotice_content(),FontChinese));
			table.addCell(new Paragraph(datafDateFormat.format(hjllist.get(i).getNotice_time()),FontChinese));
			table.addCell(new Paragraph(hjllist.get(i).getCreateUser(),FontChinese));
		//	table.addCell(new Paragraph(hjllist.get(i).getAlarmtravel().toString(),FontChinese));
		//	table.addCell(new Paragraph(hjllist.get(i).getQualifiedrate(),FontChinese));	
		}
		
		document.add(table);
		 
		document.close();
		response.setHeader("Content-Disposition", "attachment; filename=" + java.net.URLEncoder.encode(fileName, "UTF-8"));
		response.setContentType("application/pdf");
		response.setContentLength(bos.size());
						
		OutputStream out1=response.getOutputStream();
						
		bos.writeTo(out1);
		out1.flush();
	
	}
