ueditor 上传文件到ftp java

来源:互联网 发布:flash for mac安装 编辑:程序博客网 时间:2024/06/05 18:59

最近用到 富文本编辑器 发现 ueditor 界面还挺漂亮的,就选择用它了,由于默认的上传图片是保存到 tomcat/webapps/项目下面的,这样肯定是不合适的,万一重新部署,之前的

数据就有可能丢失了,所以呢想着把图片文件传到ftp下做永久保存,但是问题来了,ue没提供这种办法,只能自己拓展了,好在是开源的就方便多了,在这里特别感谢一下

先说一下原理

1、统一入口是 controller.jsp这个文件

2、通过解析config.json文件进行上传

3、上传完成以后会返回一个json串通过State 来封装源码里面有

格式:

{"state": "SUCCESS","title": "1459149871185023084.png","original": "filescan.png","type": ".png","url": "图片路径","size": "4282"}
前台就会解析到以上信息进行图片预览显示

稍后会把我本地的实现上传到百度云供大家下载

用这个 无需导入ueditor-1.1.2.jar这个包了

下载地址:http://pan.baidu.com/s/1pKDgkvL

csdn 可能不经常上,有问题加我QQ 695438455

下面直接上配置文件 直接给大家截图了

config.json 文件


ueditor.config.js 文件修改地方


修改为你自己的项目路径不修改的话页面不会创建成功,ueditor就是官网下载的文件,我给他重命名了。

这两个地方修改完成剩下的就是修改 ue的java源码了

源码结构


一下修改的代码只贴 修改部分,供大家看一下,全部的代码会给大家共享到百度云

先修改 ActionEnter 的invoke()方法

case ActionMap.UPLOAD_IMAGE:case ActionMap.UPLOAD_SCRAWL:case ActionMap.UPLOAD_VIDEO:case ActionMap.UPLOAD_FILE:conf = this.configManager.getConfig( actionCode );//用户ftp上传    conf.put("useFtpUpload",this.configManager.getAllConfig().getString("useFtpUpload"));    conf.put("keepLocalFile",this.configManager.getAllConfig().getString("keepLocalFile"));state = new Uploader( request, conf ).doExec();break;



接下来修改 Uploader

public final State doExec() {String filedName = (String) this.conf.get("fieldName");State state = null;if ("true".equals(this.conf.get("isBase64"))) {state = Base64Uploader.save(this.request.getParameter(filedName),this.conf);} else {//ftp上传判断 if("true".equals(this.conf.get("useFtpUpload"))){              state = FtpUploadUtilbaidu.save(request, conf); } else{state = BinaryUploader.save(this.request, this.conf);//系统默认的上传方法必须带着 }}return state;}


大家可能看到 FtpUploadUtilbaidu 这个是自己创建的,里面的方法和BinaryUploader都一样,只是做了一些修改红色部分

public static final State save(HttpServletRequest request,Map<String, Object> conf) {FileItemStream fileStream = null;boolean isAjaxUpload = request.getHeader( "X_Requested_With" ) != null;if (!ServletFileUpload.isMultipartContent(request)) {return new BaseState(false, AppInfo.NOT_MULTIPART_CONTENT);}ServletFileUpload upload = new ServletFileUpload(new DiskFileItemFactory());        if ( isAjaxUpload ) {            upload.setHeaderEncoding( "UTF-8" );        }try {FileItemIterator iterator = upload.getItemIterator(request);while (iterator.hasNext()) {fileStream = iterator.next();if (!fileStream.isFormField())break;fileStream = null;}if (fileStream == null) {return new BaseState(false, AppInfo.NOTFOUND_UPLOAD_DATA);}String savePath = (String) conf.get("savePath");String originFileName = fileStream.getName();String suffix = FileType.getSuffixByFilename(originFileName);originFileName = originFileName.substring(0,originFileName.length() - suffix.length());savePath = savePath + suffix;long maxSize = ((Long) conf.get("maxSize")).longValue();if (!validType(suffix, (String[]) conf.get("allowFiles"))) {return new BaseState(false, AppInfo.NOT_ALLOW_FILE_TYPE);}savePath = PathFormat.parse(savePath, originFileName);String remoteDir = "";            <span style="color:#ff0000;">int pos = savePath.lastIndexOf("/");      if(pos > -1){          remoteDir = savePath.substring(0,pos + 1);      }</span>String physicalPath = (String) conf.get("rootPath") + savePath;//是否上传后保留本地服务器文件config.json,里面的配置<span style="color:#ff0000;">boolean keepLocalFile = "false".equals(conf.get("keepLocalFile")) ? false : true;</span>InputStream is = fileStream.openStream();//调用自己ftp上传方法<span style="color:#ff0000;">State storageState = StorageManager.saveFtpFileByInputStream(is, remoteDir,        physicalPath, maxSize, keepLocalFile);</span>//State storageState = StorageManager.saveFileByInputStream(is,//physicalPath, maxSize);is.close();if (storageState.isSuccess()) {//这里的默认url是 ue 配置文件config-imagePathFormat属性的路径,这里我需要替换成ftp的路径//storageState.putInfo("url", PathFormat.format(savePath));storageState.putInfo("type", suffix);storageState.putInfo("original", originFileName + suffix);}return storageState;} catch (FileUploadException e) {return new BaseState(false, AppInfo.PARSE_REQUEST_ERROR);} catch (IOException e) {}return new BaseState(false, AppInfo.IO_ERROR);}

下面提供 ftp 上传方法 ,
<span style="color:#ff0000;">saveFtpFileByInputStream 这个方法就不贴了,下载了到代码找吧</span>
<span style="color:#ff0000;"></span>
/**   * ftp上传文件   *    * */  private static State saveFtpTmpFile(File tmpFile, String remoteDir, String path,boolean keepLocalFile) {        State state = null;//用来拼装 上传成功后返回的json串        File targetFile = new File(path);        String share_img=null;//得到上传图片路径        if (targetFile.canWrite())          return new BaseState(false, 2);        try        {          FileUtils.moveFile(tmpFile, targetFile);        } catch (IOException e) {          return new BaseState(false, 4);        }                try        {        String module = "imagesjkzx";        String timepoint = new SimpleDateFormat("yyyyMMddHHmmssSSS").format(new Date());        String[] param = { null, module, timepoint };        //下面是上传方法,我就不贴了,需求都不一样,具体的ftp上传方法,自己网上找找吧有的是,需要注意的是上传完以后必须能够得到ftp路径 share_img = FtpUploadUtil.ftpUpload(targetFile, param);        System.out.println("share_img"+share_img);                }catch (Exception e) {        System.out.println(e.getMessage());            return new BaseState(false, 4);        }                try        {            if(! keepLocalFile)                targetFile.delete();        }catch(Exception e){                    }        state = new BaseState(true);        state.putInfo("url", share_img);//刚才注释了一个url,现在我是在这里赋值的,share_img就是ftp的路径        state.putInfo("size", targetFile.length());        state.putInfo("title", targetFile.getName());        return state;  }

到这里就差不多了。
