今天跟大家分享一下工作中比较实用的导出word 带图片的功能。
对于在idea开发中我们需要引入以下依赖：
2.对于eclipse 开发我们需要进入对应的jar包
这个必须放在lib下，同样也需要在当前项目的环境是加入该依赖
需要在MEAT-INF加入
首先制定word 导出模版格式，用占位符进行代替
对于插入的图片提前设置好大小格式
编写好后：进行另存为 html 格式或者xml
接着用编辑文本打开修改里面的内容
对于插入图片的时候请注意：在src 的时候也用占位符。
注意：所有的占位符要与代码中的Hashmap 中的key，保持一致。
编写代码：
@RequestMapping(value = "/exportWord")public void exportWord(HttpServletRequest request, HttpServletResponse response, @RequestParam(value = "id") String id ) throws Exception{List<Map<String, Object>> list = new ArrayList<Map<String,Object>>();ArrayList<String> parameters = new ArrayList<String>();List<Map<String,Object>> queryResult2 = limitspaceworkBizc.findyxkjzydc(id);if(queryResult2.size()>0){list.add(queryResult2.get(0));}Map<String, Object> query = list.get(0);exportWord(request, response, query, "明细表.docx",id);}public void exportWord(HttpServletRequest request,HttpServletResponse response, Map<String, Object> query, String fileName,String id) throws IOException, InvalidFormatException {//获取 模版的路径String pathString = request.getSession().getServletContext().getRealPath("/WEB-INF/templete/");System.out.println("获取到的模板路径是：templetePath------->" + pathString);Configuration configuration = new Configuration(new Version("2.3.23"));configuration.setDefaultEncoding("utf-8");configuration.setDirectoryForTemplateLoading(new File(pathString));Template freemarkerTemplate = configuration.getTemplate("yxkjzydmysd.ftl");File file = null;InputStream fin = null;ServletOutputStream out = null;try {String SPDimage =null;List<LimitSpaceWorkExportpo> vos = new ArrayList<LimitSpaceWorkExportpo>();LimitSpaceWorkExportpo aa= new LimitSpaceWorkExportpo();Map<String,Object> map3=limitspaceworkBizc.findrwtp(id);Map<String,Object> map = new HashMap<String,Object>();map.put("BH", query.get("BH")==null?"":query.get("BH").toString());map.put("ZCGLDW", query.get("ZCGLDW")==null?"":query.get("ZCGLDW").toString());map.put("SZDQ", query.get("SZDQ")==null?"":query.get("SZDQ").toString());map.put("ZYLX", query.get("ZYLX")==null?"":query.get("ZYLX").toString());map.put("ZYMC", query.get("ZYMC")==null?"":query.get("ZYMC").toString());map.put("GCXZ", query.get("GCXZ")==null?"":query.get("GCXZ").toString());map.put("GCZZDW", query.get("GCZZDW")==null?"":query.get("GCZZDW").toString());map.put("LXR", query.get("LXR")==null?"":query.get("LXR").toString());map.put("LXDH", query.get("LXDH")==null?"":query.get("LXDH").toString());map.put("ZYFW", query.get("ZYFW")==null?"":query.get("ZYFW").toString());map.put("ZYNR", query.get("ZYNR")==null?"":query.get("ZYNR").toString());map.put("ZYSQR", query.get("ZYSQR")==null?"":query.get("ZYSQR").toString());map.put("ZYDW", query.get("ZYDW")==null?"":query.get("ZYDW").toString());map.put("ZYSQRDH", query.get("ZYSQRDH")==null?"":query.get("ZYSQRDH").toString());map.put("XCFZR", query.get("XCFZR")==null?"":query.get("XCFZR").toString());map.put("XCFZRDH", query.get("XCFZRDH")==null?"":query.get("XCFZRDH").toString());map.put("AQXYS", map3.get("AQXYS")==null?"":map3.get("AQXYS").toString());map.put("SPD", map3.get("SPD")==null?"":map3.get("SPD").toString());map.put("CND", map3.get("CND")==null?"":map3.get("CND").toString());map.put("GZS", map3.get("GZS")==null?"":map3.get("GZS").toString());map.put("GJCX", map3.get("GJCX")==null?"":map3.get("GJCX").toString());// 调用工具类的createDoc方法生成Word文档file = createDoc(map,freemarkerTemplate);fin = new FileInputStream(file);response.setCharacterEncoding("utf-8");response.setContentType("application/msword");// 设置浏览器以下载的方式处理该文件名fileName = URLEncoder.encode("断面验收报告" + ".docx", "UTF-8");response.setHeader("Content-disposition", "attachment; filename="+ fileName + ";filename*=utf-8" + fileName);out = response.getOutputStream();byte[] buffer = new byte[512]; // 缓冲区int bytesToRead = -1;// 通过循环将读入的Word文件的内容输出到浏览器中while((bytesToRead = fin.read(buffer)) != -1) {out.write(buffer, 0, bytesToRead);}} finally {if(fin != null) fin.close();if(out != null) out.close();if(file != null) file.delete(); // 删除临时文件}}
指定编码格式：
private static File createDoc(Map<String, Object> dataMap, Template template) {String name = ".doc";File f = new File(name);Template t = template;try {// 这个地方不能使用FileWriter因为需要指定编码类型否则生成的Word文档会因为有无法识别的编码而无法打开Writer w = new OutputStreamWriter(new FileOutputStream(f), "utf-8");t.process(dataMap, w);w.close();} catch (Exception ex) {ex.printStackTrace();throw new RuntimeException(ex);}return f;}
