【ckeditor系列】ckeditor 图片上传最新完美处理

ckeditor的不可以上传图片，ckfinder又要收费，当然如果你是用的php，那么你可以用kcfinder，免费的。

那怎么解决呢？

ckeditor 图片上传最新完美处理

 

需要做的有以下几步： 
1. 到官网下载ckeditor，网址：http://ckeditor.com/download 
2. 复制到java web项目目录下 
3. 配置config文件，打开图片上传功能 
   

CKEDITOR.editorConfig = function (config) {  
// 换行方式  
    config.enterMode = CKEDITOR.ENTER_BR;  
  
    // 当输入：shift+Enter是插入的标签  
    config.shiftEnterMode = CKEDITOR.ENTER_BR;//   
    //图片处理  
    config.pasteFromWordRemoveStyles = true;  
    config.filebrowserImageUploadUrl = "ckUploadImage.action?type=image";  
      
    // 去掉ckeditor“保存”按钮  
    config.removePlugins = 'save';  
};

** 在这里另附flex引用ckeditor 编辑器默认全屏方法： 
修改ckeditor.html页面： 

<script type="text/javascript">  
        if ( typeof CKEDITOR == 'undefined' )  
        {  
          document.write('加载失败') ;  
        }  
        else  
        {  
          //var editor = CKEDITOR.replace( 'editor1',  
          //     {  
            //      customConfig: "news_ck_config.js"  
        //      });  
           
          var editor = CKEDITOR.replace( 'editor1');  
                  
          CKEDITOR.on('instanceReady', function(evt){  
             var editor = evt.editor;  
             editor.execCommand('maximize');  
          });  
        }  
  
</script>

4. java后台处理代码 

// 上传图片  
    @Action(value = "/ckUploadImage", results = { @Result(name = "success", location = "/upload.jsp") })  
    public String uploadImages() throws Exception {  
        HttpServletRequest request = ServletActionContext.getRequest();  
        FileOutputStream fos;  
        String webRoot = request.getSession().getServletContext().getRealPath(  
                "");  
        // 获取图片后缀名  
        String partRightType = uploadFileName.substring(uploadFileName  
                .lastIndexOf("."));  
        String CKEditorFuncNum = request.getParameter("CKEditorFuncNum");  
        // 判断图片的格式  
        if (!ImageFile.checkImageType(partRightType)) {  
            String path = "";  
            String alt_msg = "Sorry! Image format selection is incorrect, please choose GIF, jpeg, PNG format JPG, picture!";  
            pringWriterToPage("<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction("  
                    + CKEditorFuncNum  
                    + ", '"  
                    + path  
                    + "' , '"  
                    + alt_msg  
                    + "');</script>");  
        } else {  
            try {  
  
                uploadFileName = DateUtils.getDateNoStyle() + "-"  
                        + UUID.randomUUID() + partRightType;  
  
                String savePath = webRoot + Constants.UPLOAD_IMAGES_PATH;  
                File uploadFilePath = new File(savePath);  
                if (uploadFilePath.exists() == false) {  
                    uploadFilePath.mkdirs();  
                    System.out.println("路径不存在,但是已经成功创建了" + savePath);  
                } else {  
                    System.out.println("路径存在了" + savePath);  
                }  
                fos = new FileOutputStream(new File(savePath + uploadFileName));  
                FileInputStream fis = new FileInputStream(getUpload());  
                byte[] buffer = new byte[1024];  
                int len = 0;  
                while ((len = fis.read(buffer)) > 0) {  
                    fos.write(buffer, 0, len);  
                }  
                fos.close();  
                fis.close();  
            } catch (FileNotFoundException foe) {  
                System.out.println("上传文件为0字节");  
            }  
  
            // String path = "http://" + request.getServerName() + ":"  
            // + request.getServerPort() + request.getContextPath()  
            // + Constants.UPLOAD_IMAGES_PATH + uploadFileName;  
  
            String path = request.getContextPath()  
                    + Constants.UPLOAD_IMAGES_PATH + uploadFileName;  
            String alt_msg = "";  
            pringWriterToPage("<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction("  
                    + CKEditorFuncNum  
                    + ", '"  
                    + path  
                    + "' , '"  
                    + alt_msg  
                    + "');</script>");  
  
        }  
  
        return null;  
    }
