使用itext導出多個 數據庫中的富文本html標籤(帶佔位符可替換的)的word文檔並壓縮

首先引入 itext 需要的jar包 

      <dependency>
	      <groupId>com.lowagie</groupId>
	      <artifactId>iText</artifactId>
	      <version>2.1.3</version>
	  </dependency>
	  <dependency>
	      <groupId>com.lowagie</groupId>
	      <artifactId>itext-rtf</artifactId>
	      <version>2.1.3</version>
	  </dependency>

其次是我們的controller 從前端接收到 必要的參數 ，從數據庫得到自己想要導出的富文本內容其次導出word

    @RequestMapping("/externalVisitToBeReviewed")
	@ResponseBody
	public ResultBean externalVisitToBeReviewed(HttpServletRequest request, HttpServletResponse response, String casIds,
			String chIds, String paths) throws IOException {
		ResultBean resultBean = new ResultBean();
        //這個是我查詢數據庫的方法 換成你自己的內容即可
		DocTemplate docTemplate = 
        docTemplateService.selectDocTemplateById(Long.valueOf(paths));
		String content = docTemplate.getTmpHtml();
		String[] casIdArray = casIds.split(",");
		String[] chIdArray = chIds.split(",");
        //這裏生成你要導出之後的壓縮包名字
		String zipName = new Date().getTime() + ".zip";
        //下面註釋掉的這句如果 前段沒有設置的話 最好不寫 要不然 壓縮包可能會打不開
//		response.setContentType("APPLICATION/OCTET-STREAM");
        //設置請求頭
		response.setHeader("Content-Disposition", "attachment; filename=" + zipName);
		ZipOutputStream out = new ZipOutputStream(response.getOutputStream());
		try {
			File file = new File(wordTemplate);
            //這裏判斷下選中的導出的文件夾是否存在 如果不存在 就自己創建
			if(!file.exists()){
				file.mkdirs();
			}
            //循環我上面的條件 如果循環三次 最後導出的壓縮包中就有三個word文檔
			for (int i = 0; i < casIdArray.length; i++) {
                 //循環裏的 是真正導出word的方法 這裏調用下
				String path = wordTemplate + new Date().getTime() + ".doc";
				wordService.externalVisitToBeReviewed(request, response, casIdArray[i], chIdArray[i], path, content);
			}
            //這裏把剛剛導出word的文件夾壓縮 然後返回給前臺
			ZipUtils.doCompress(wordTemplate, out);
			response.flushBuffer();
			resultBean.put("msg", "下載成功");
			resultBean.put("code", "1");
		} catch (Exception e) {
			e.printStackTrace();
			resultBean.put("msg", "下載失敗");
			resultBean.put("code", "0");
		} finally {
			out.close();
            //這裏是對下載到本地的word進行下 刪除操作 要不然下次再下載 這次的 也會跟着下載下去
			FileUploadUtils.deleteFileCCDS(wordTemplate);
		}
		return resultBean;
	}

下面這個是itext 導出word的方法

@Override
	public String externalVisitToBeReviewed(HttpServletRequest request,HttpServletResponse response, String casId,String chId,String path,String content) throws Exception {
        //這裏是我封裝的一個model 用來替換富文本中的佔位符用的
		Placeholder placeholder = new Placeholder(Long.valueOf(casId), !"".equals(chId)?Long.valueOf(chId):null, bankCaseMapper, caseHpMapper, salEmpMapper, typeListMapper);
		OutputStream out = new FileOutputStream(path);  
        Document document = new Document(PageSize.A4);  
        RtfWriter2.getInstance(document, out);  
        document.open();  
        Paragraph context = new Paragraph();
        StyleSheet ss = new StyleSheet();  
        //這裏是 判斷 數據庫的富文本中有沒有某個佔位符 然後進行替換
        content = replacePlaceholder(content, placeholder);
        List htmlList = HTMLWorker.parseToList(new StringReader(content), ss);  
        for (int i = 0; i < htmlList.size(); i++) {  
            com.lowagie.text.Element e = (com.lowagie.text.Element) htmlList  
                    .get(i);  
            context.add(e);  
        }  
			document.add(context);
        document.close();  
        System.out.println("ok");  
		return path;

	}

最後是我替換的 方法 你們可以按自己需求自己定義 我這裏只是舉個例子

public String replacePlaceholder(String content,Placeholder placeholder){
		if(content.contains("${caseID}")){
			String caseID = placeholder.getCaseID();
			System.out.println(caseID);
