CKEditor实现图片上传

本人用的CKEditor版本为4.3 CKEditor配置和部署参考CKEditor4.x部署和配置。
CKEditor编辑器的工具栏中初始的时候应该是这样子的,没有图片上传按钮


并且预览中有一堆火星文,可以修改相应配置删除它。
第一种方法:打开ckeditor/plugins/image/dialogs/image.js文件,搜索“b.config.image_previewText”,(b.config.image_previewText||‘‘)单引号中的内容全删了,注意别删多了。(由于ckeditor的很多js文件都是压缩过的,格式很难看,很容易删错,所以不推荐此种方法)
第二种方法:打开config.js文件,加入下面一句话
config.image_previewText=‘ ‘; //预览区域显示内容

下面研究图片上传
要想出现上传按钮,两种方法
第一种:还是刚才那个image.js
搜索“upload”可以找到这一段 id:‘Upload‘,hidden:true,而我使用的4.3的是
id:"Upload",hidden:!0,反正改为false就行了,(遗憾的是此种方法对我这个版本不起作用)
第二种:打开config.js文件,加入下面一句话
config.filebrowserImageUploadUrl= "admin/UserArticleFileUpload.do"; //待会要上传的action或servlet

OK现在基本上是下面这个样子的了




上面的只是一个上传页面。也就相当于一个HTML的form表单,
要配置点击"上传到服务器上"按钮后请求的Action。已在ckeditor/config.js中配置。
就是上面的 config.filebrowserImageUploadUrl = "admin/UserArticleFileUpload.do";
可使用chrome审查元素查看代码

接下来就是action中的上传方法:
public class ImageUpload extends WebSupport {      private File upload;       //文件      private String uploadContentType;   //文件类型      private String uploadFileName;       //文件名      /**      * 图片上传      * @return      * @throws IOException       */      public String fileUpload() throws IOException{          //HttpServletResponse response = ServletActionContext.getResponse();          getResponse().setCharacterEncoding("utf-8");          PrintWriter out =  getResponse().getWriter();            // CKEditor提交的很重要的一个参数            String callback = getRequest().getParameter("CKEditorFuncNum");          String expandedName = "";  //文件扩展名            if (uploadContentType.equals("image/pjpeg") || uploadContentType.equals("image/jpeg")) {                //IE6上传jpg图片的headimageContentType是image/pjpeg,而IE9以及火狐上传的jpg图片是image/jpeg                expandedName = ".jpg";            }else if(uploadContentType.equals("image/png") || uploadContentType.equals("image/x-png")){                //IE6上传的png图片的headimageContentType是"image/x-png"                expandedName = ".png";            }else if(uploadContentType.equals("image/gif")){                expandedName = ".gif";            }else if(uploadContentType.equals("image/bmp")){                expandedName = ".bmp";            }else{                out.println("<script type=\"text/javascript\">");                  out.println("window.parent.CKEDITOR.tools.callFunction(" + callback + ",‘‘," + "‘文件格式不正确(必须为.jpg/.gif/.bmp/.png文件)‘);");                 out.println("</script>");                return null;            }            if(upload.length() > 600*1024){                out.println("<script type=\"text/javascript\">");                  out.println("window.parent.CKEDITOR.tools.callFunction(" + callback + ",‘‘," + "‘文件大小不得大于600k‘);");                 out.println("</script>");                return null;            }                        InputStream is = new FileInputStream(upload);            String uploadPath = ServletActionContext.getServletContext().getRealPath("/img/uploadImg");            String fileName = java.util.UUID.randomUUID().toString();  //采用时间+UUID的方式随即命名            fileName += expandedName;            File file = new File(uploadPath);          if(!file.exists()){  //如果路径不存在,创建              file.mkdirs();          }          File toFile = new File(uploadPath, fileName);            OutputStream os = new FileOutputStream(toFile);               byte[] buffer = new byte[1024];               int length = 0;            while ((length = is.read(buffer)) > 0) {                   os.write(buffer, 0, length);               }               is.close();            os.close();                        // 返回"图像"选项卡并显示图片            out.println("<script type=\"text/javascript\">");              out.println("window.parent.CKEDITOR.tools.callFunction(" + callback + ",‘" + "/eHomePlus/img/uploadImg" + fileName + "‘,‘‘)");              out.println("</script>");            return null;      }      public File getUpload() {          return upload;      }      public void setUpload(File upload) {          this.upload = upload;      }      public String getUploadContentType() {          return uploadContentType;      }      public void setUploadContentType(String uploadContentType) {          this.uploadContentType = uploadContentType;      }      public String getUploadFileName() {          return uploadFileName;      }      public void setUploadFileName(String uploadFileName) {          this.uploadFileName = uploadFileName;      }  }
 config.js
CKEDITOR.editorConfig = function( config ) {      config.filebrowserImageUploadUrl = "admin/UserArticleFileUpload.do"; //固定路径      config.image_previewText=‘ ‘; //预览区域显示内容   };
最后上传图片成功
