前台页面：
<script type="text/javascript" charset="utf-8" src="/script/ueditor/ueditor.config.js"></script> <script type="text/javascript" charset="utf-8" src="/script/ueditor/ueditor.all.min.js"></script>
<a id="btnDownloadWord" class="mini-button fake-no-status" οnclick="downloadWord()">下载Word</a>
downloadWord: function(e) { mini.get('btnDownloadWord').setEnabled(false); var data = {content: encodeURIComponent(getUEEditor().getContent()), name: encodeURIComponent(getForm().getData().contractname)}; var inputs = '<input type="hidden" name="content" value="'+data.content+'"/>'; inputs += '<input type="hidden" name="name" value="'+data.name+'"/>'; jQuery('<form method="post" action="/richeditor/exportWord.do">'+inputs+'</form>').appendTo('body').submit().remove(); mini.get('btnDownloadWord').setEnabled(true); }
后台处理：
public void exportWord() { OutputStream os = null; ByteArrayInputStream bais = null; POIFSFileSystem poifs = null; String method = request.getMethod(); try { if (POST.equalsIgnoreCase(method)) { String content = URLDecoder.decode(request.getParameter("content"), UTF8); String name = URLDecoder.decode(request.getParameter("name"), UTF8); byte[] buf = buildContent(content).getBytes(); bais = new ByteArrayInputStream(buf); poifs = new POIFSFileSystem(); DirectoryEntry directory = poifs.getRoot(); directory.createDocument("WordDocument", bais); response.reset(); response.addHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode(name + ".doc", UTF8)); response.setContentType("application/msword"); os = new BufferedOutputStream(response.getOutputStream()); poifs.writeFilesystem(os); os.flush(); } else if (GET.equalsIgnoreCase(method)) { } } catch (Exception e) { e.printStackTrace(); } finally { try { if (null != bais) { bais.close(); } if (null != os) { os.close(); } if (null != poifs) { poifs.close(); } } catch (IOException e) { e.printStackTrace(); } } }
private String buildContent(String content) throws Exception { VelocityEngine ve = new VelocityEngine(); Properties p = new Properties(); p.put(Velocity.FILE_RESOURCE_LOADER_PATH,this.getClass().getClassLoader().getResource("conf/template").getPath()); //模板路径 ve.init(p); Template template = ve.getTemplate("richeditor.vm", UTF8); //获取模板 VelocityContext context = new VelocityContext(); context.put("content", content); StringWriter writer = new StringWriter(); template.merge(context, writer); return writer.toString(); }
注意：
this.getClass().getResource("/").getPath() 获取classes根路径
在Windows下的路径分隔符和Linux下的路径分隔符是不一样的，当直接使用绝对路径时，跨平台会暴出“No such file or diretory”的异常。
如果要考虑跨平台，则最好是这么写：File myFile = new File("C:" + File.separator + "tmp" + File.separator, "test.txt");
