公司用的是阿里云的图片服务器，需要直接把文章中图片上传到服务器上，但是这个编辑器的上传图片是直接上传到Tomcat的根目录。
不能满足要求，尝试改造了一下上传图片的功能。
下载下来的编辑器直接导入项目webapp目录下
因为用的是Spring框架，基本已经包含了ueditor需要的几个jar包，所以不需要导入了。
需要注意的是，这个ueditor-1.1.1.jar的这个jar包，其实不需要导入，因为这个包里面就只有一个文件Uploader.java
而在ueditor的jsp目录下已经有了Uploader.java文件，所以直接把这个文件copy到工作区中，访问这个文件就可以了。
在调用的地方改一下目录
把
<%@ page import="com.baidu.ueditor.um.Uploader" %>
改成
<%@ page import="com.myproject.upload.Uploader"%>
如下图：
然后关键就是要改造一下Uploader.java这个类。
原有上传代码如下：
| 代码如下 | 复制代码 |
|
public void upload() throws Exception { boolean isMultipart = ServletFileUpload.isMultipartContent(this.request); if (!isMultipart) { this.state = this.errorInfo.get("NOFILE"); return; } DiskFileItemFactory dff = new DiskFileItemFactory(); String savePath = this.getFolder(this.savePath); dff.setRepository(new File(savePath)); try { ServletFileUpload sfu = new ServletFileUpload(dff); sfu.setSizeMax(this.maxSize * 1024); sfu.setHeaderEncoding("utf-8"); FileItemIterator fii = sfu.getItemIterator(this.request); while (fii.hasNext()) { FileItemStream fis = fii.next(); if (!fis.isFormField()) { this.originalName = fis.getName().substring(fis.getName().lastIndexOf(System.getProperty("file.separator")) + 1); if (!this.checkFileType(this.originalName)) { this.state = this.errorInfo.get("TYPE"); continue; } this.fileName = this.getName(this.originalName); this.type = this.getFileExt(this.fileName); // 获取了存放文件的相对路径 this.url = savePath + "/" + this.fileName; BufferedInputStream in = new BufferedInputStream(fis.openStream()); File file = new File(this.getPhysicalPath(this.url)); FileOutputStream out = new FileOutputStream( file ); BufferedOutputStream output = new BufferedOutputStream(out); // 这里直接在服务器根目录生成了图片文件 Streams.copy(in, output, true); this.state=this.errorInfo.get("SUCCESS"); this.size = file.length(); //UE中只会处理单张上传，完成后即退出 break; } else { String fname = fis.getFieldName(); //只处理title，其余表单请自行处理 if(!fname.equals("pictitle")){ continue; } BufferedInputStream in = new BufferedInputStream(fis.openStream()); BufferedReader reader = new BufferedReader(new InputStreamReader(in)); StringBuffer result = new StringBuffer(); while (reader.ready()) { result.append((char)reader.read()); } this.title = new String(result.toString().getBytes(),"utf-8"); reader.close(); } } } catch (SizeLimitExceededException e) { this.state = this.errorInfo.get("SIZE"); } catch (InvalidContentTypeException e) { this.state = this.errorInfo.get("ENTYPE"); } catch (FileUploadException e) { this.state = this.errorInfo.get("REQUEST"); } catch (Exception e) { this.state = this.errorInfo.get("UNKNOWN"); } } |

修改后：
| 代码如下 | 复制代码 |
|
// 改造后的代码，百度原有代码注释了 public void upload() throws Exception { boolean isMultipart = ServletFileUpload.isMultipartContent(this.request); if (!isMultipart) { this.state = this.errorInfo.get("NOFILE"); return; } try { MultipartResolver resolver = new CommonsMultipartResolver( this.request.getSession().getServletContext()); MultipartHttpServletRequest multipartRequest = resolver.resolveMultipart(request); CommonsMultipartFile orginalFile = (CommonsMultipartFile) multipartRequest.getFile("upfile"); this.originalName = orginalFile.getOriginalFilename(); if (!this.checkFileType(this.originalName)) { this.state = this.errorInfo.get("TYPE"); return; } this.type = this.getFileExt(this.originalName); this.size = orginalFile.getSize(); // 这里是公司内部上传到阿里云服务器的工具类 String key = ImgUtils.uploadImage("xxxx", ImageKind.Picture, orginalFile.getInputStream(), this.size); this.fileName = key; this.url = "http://xxx.aliyuncs.com/" + key; this.state = this.errorInfo.get("SUCCESS"); } catch (Exception e) { this.state = this.errorInfo.get("UNKNOWN"); } } |
|
用到了Spring的这两个文件
| 代码如下 | 复制代码 |
|
import org.springframework.web.multipart.commons.CommonsMultipartFile; import org.springframework.web.multipart.commons.CommonsMultipartResolver; |
|
然后编辑器页面上显示的时候，img的src目录需要改一下
| 代码如下 | 复制代码 |
|
callback: function (editor, $w, url, state) { if (state == "SUCCESS") { //显示图片计数+1 Upload.showCount++; var $img = $("<img src='" + editor.options.imagePath + url + "' class='edui-image-pic' />"), var $img = $("<img src='" + url + "' class='edui-image-pic' />"), $item = $("<div class='edui-image-item edui-image-upload-item'><div class='edui-image-close'></div></div>").append($img); if ($(".edui-image-upload2", $w).length < 1) { $(".edui-image-content", $w).append($item); Upload.render(".edui-image-content", 2) .config(".edui-image-upload2"); } else { $(".edui-image-upload2", $w).before($item).show(); } $img.on("load", function () { Base.scale(this, 120); Base.close($(this)); $(".edui-image-content", $w).focus(); }); } else { currentDialog.showTip( state ); window.setTimeout( function () { currentDialog.hideTip(); }, 3000 ); } Upload.toggleMask(); } |
