CKEditor和UEditor使用比较
本来项目中使用CKEditor已经做好了的富文本编辑器的功能,但是业务考虑到美观性要求换成UEditor,所以就在这里总结下
先说下使用这两个不同插件的感想,我用的ueditor是1.4.3的版本:(ueditor API)
CKEditor的使用
在jsp页面下引入ckeditor下的ckeditor.js(当然首先要引入jQuery.js,引入插件类库ckeditor-Java-core-3.5.3.jar)
<script type="text/javascript" src="${basePath}/js/ckeditor/ckeditor.js"></script>
//引入js后在textarea标签上添加一个richText=”true”这个属性即可
<textarea name="wxChoiceInfo.infoTextConte" id="wxChoiceInfoInfoTextConte" richText="true" cols="110" rows="15"></textarea>
获取ckeditor中的内容
Var content = CKEDITOR.instances.wxChoiceInfoInfoTextConte.getData(content); //初始化 $(function() { //富文本字段初始化 $("[richText]").each(function (e) { CKEDITOR.replace($(this).attr("id"),{ height : 400, skin : 'kama', language : 'zh-cn', filebrowserImageUploadUrl:'${basePath}/wxdate/ck_upload.action?fileType=1', toolbar: 'ToolbarCommon', resize_enabled: false }); }); });
Action配置
<!-- FckEdit上传--> <action name="ck_upload" class="com.ccxe.wxdate.action.CkeditorUploadAction"> <param name="fileSize"></param> <!-- 上传文件大小 --> </action>
CkeditorUploadAction类源码
//CkeditorUploadAction类源码 public class CkeditorUploadAction extends ActionSupport { private static final long serialVersionUID = 1L; private File upload; private String uploadContentType; private String uploadFileName; //文件大小 private long fileSize; //取文件路径 private String fileType; public String getFileType() { return fileType; } public void setFileType(String fileType) { this.fileType = fileType; } public long getFileSize() { return fileSize; } public void setFileSize(long fileSize) { this.fileSize = fileSize; } 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; } public String execute() throws Exception { try { HttpServletResponse response = ServletActionContext.getResponse(); response.setContentType("text/html;charset=UTF-8"); PrintWriter out = response.getWriter(); String callback = ServletActionContext.getRequest().getParameter("CKEditorFuncNum"); //对文件进行校验 if(upload==null || uploadContentType==null || uploadFileName==null){ //out.print("<font color=\"red\" size=\"2\">*请选择上传文件</font>"); String path = ""; String alt_msg = "*请选择上传文件"; out.print("<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction(" + callback + ", '" + path + "' , '" + alt_msg + "');</script>"); return null; } if ((uploadContentType.equals("image/pjpeg") || uploadContentType.equals("image/jpeg")) && (uploadFileName.substring(uploadFileName.length() - 4).toLowerCase().equals(".jpg")||uploadFileName.substring(uploadFileName.length() - 5).toLowerCase().equals(".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 }else if((uploadContentType.equals("image/x-png") || uploadContentType.equals("image/png")) && uploadFileName.substring(uploadFileName.length() - 4).toLowerCase().equals(".png")){ }else if(uploadContentType.equals("image/gif") && uploadFileName.substring(uploadFileName.length() - 4).toLowerCase().equals(".gif")){ }else if(uploadContentType.equals("image/bmp") && uploadFileName.substring(uploadFileName.length() - 4).toLowerCase().equals(".bmp")){ }else{ //out.print("<script language=\"javascript\">alert(\"*文件格式不正确(必须为.jpg/.gif/.bmp/.png文件)\");return false;</script>"); String path = ""; String alt_msg = "*请选择图片文件格式(必须为.jpg/.jpeg/.gif/.bmp/.png文件)"; out.print("<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction(" + callback + ", '" + path + "' , '" + alt_msg + "');</script>"); return null; } if(upload.length() > this.getFileSize()){ //out.print("<font color=\"red\" size=\"2\">*文件大小不得大于"+this.getFileSize()/(1000*1024)+"m</font>"); String path = ""; String alt_msg = "*请选择上传"+this.getFileSize()/(1000*1024)+"M以内的图片文件"; out.print("<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction(" + callback + ", '" + path + "' , '" + alt_msg + "');</script>"); return null; } String imagePath = ""; //imagePath路径的设置 WebApplicationContext wac = ContextLoader.getCurrentWebApplicationContext(); WxConfig wxConfig = (WxConfig)wac.getBean("wxConfig"); //if(fileType.equals(PubParaConstants.DC_CK_UPLOAD_PATTH_PARAM.DC_CK_UPLOAD_PATTH_PARAM_PROSELECT)) { imagePath = wxConfig.getFilePath(); //} //WxConfig wxConfig; File directory = new File(imagePath); if(!directory.isDirectory()) { directory.mkdirs(); } //将文件保存到项目目录下 InputStream is = new FileInputStream(upload); Date date = new Date(); // 获得系统时间,用于生成文件名 long lTime = date.getTime(); String fileName = DateUtil.toStringNoInterval(date, 8)+"_"+lTime; fileName += FileUtil.getFileSuffix(uploadFileName); File toFile = new File(imagePath, 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(); //设置返回“图像”选项卡 String callbackUrl = ServletActionContext.getRequest().getContextPath() +"/fckImageReader.servlet?fold="+this.getFileType()+"&imageName="+fileName; out.println("<script type=\"text/javascript\">"); out.println("window.parent.CKEDITOR.tools.callFunction(" + callback + ",'"+ callbackUrl + "','')"); out.println("</script>"); } catch (Exception e) { e.printStackTrace(); } return null; } }
图片回显到编辑器的servlet代码
/ * 文件流方式读取本地图片文件(图片回显处理) * FckImageReaderServlet */ public class FckImageReaderServlet extends HttpServlet { private static final long serialVersionUID = 1L; public void init() throws ServletException { } public void doGet(HttpServletRequest request, HttpServletResponse response) { this.doPost(request, response); } public void doPost(HttpServletRequest request, HttpServletResponse response) { try { //得到文件名称 String imageName = request.getParameter("imageName"); String foldType = request.getParameter("fold"); String imagePath = ""; //imagePath路径的设置 WebApplicationContext wac = ContextLoader.getCurrentWebApplicationContext(); WxConfig wxConfig = (WxConfig)wac.getBean("wxConfig");//模块配置文件 //if(fileType.equals(PubParaConstants.DC_CK_UPLOAD_PATTH_PARAM.DC_CK_UPLOAD_PATTH_PARAM_PROSELECT)) { imagePath = wxConfig.getFilePath(); //} if (imageName != null) { String imageExt = imageName.substring(imageName.lastIndexOf(".") + 1); //扩展名 //得到配置文件路径 String imageDir = imagePath+"/"+imageName; //文件全局路径 File inputFile = new File(imageDir); if (inputFile.exists()) { //BufferedImage input = ImageIO.read(inputFile); // 禁止图像缓存。 response.setHeader("Pragma", "no-cache"); response.setHeader("Cache-Control", "no-cache"); response.setDateHeader("Expires", 0); //response.setContentType("image/jpeg"); // 将图像输出到Servlet输出流中。 // ServletOutputStream sos = response.getOutputStream(); // ImageIO.write(input, imageExt, sos); // sos.flush(); // sos.close(); InputStream in = new FileInputStream(inputFile); OutputStream os = response.getOutputStream(); //创建输出流 byte[] b = new byte[1024]; while( in.read(b)!= -1){ os.write(b); } in.close(); os.flush(); os.close(); } } } catch (Exception e) { e.printStackTrace(); } } }
web.xml
Web.xml配置FckImageReaderServlet <!-- FCK --> <servlet> <servlet-name>FckReader</servlet-name> <servlet-class>com.*.common.file.FckImageReaderServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>FckReader</servlet-name> <url-pattern>/fckImageReader.servlet</url-pattern> </servlet-mapping>
再来看UEditor:
//引入相关的js和css <script type="text/javascript" src="${basePath}/js/ueditor/ueditor.config.js"></script> <script type="text/javascript" src="${basePath}/js/ueditor/ueditor.all.js"></script> <link type="text/css" rel="stylesheet" href="${basePath}/js/ueditor/themes/default/css/ueditor.css" rel="external nofollow" >
jsp页面部分代码:
<form action="<s:url value="/p2p/updateIProductServices.action"/>" method="post" id="form"> <tr id="proInvSerTr"> <th>投资服务流程 <input type="hidden" id="hidInvestProcess" name="productServices.investSerProcess"/></th> <td> <!-- 加载编辑器的容器 --> <script id="container" name="content" type="text/plain">${productServices.investSerProcess}</script> <!-- 实例化编辑器 --> <script type="text/javascript"> var ue = UE.getEditor('container'); </script> </td> </tr> <input type="button" value="保存" class="ImgButton" onclick="submitForm"/> </form> <script type="text/javascript"> function submitForm(){ $("#hidInvestProcess").val(ue.getContent()); $("#form").submit(); }
说了那么多,那使用ueditor怎么修改文件上次的路劲呢,在1.4.3版本下,找到ueditor\jsp\config.json文件
找到上次图片配置项的"imageUrlPrefix": "/", /* 图片访问路径前缀 */ "imagePathFormat": "upload/image/{yyyy}{mm}{dd}/{time}{rand:6}" //这里是我改过了的上传路径
注意要修改imageUrlPrefix,因为编辑器中图片显示路径是imageUrlPrefix+imagePathFormat,如果不修改imageUrlPrefix图片是不能正常显示的,imagePathFormat这个上传路径是相对于服务器的相对路径。
使用ueditor最主要的就是需要修改web.xml中得struts的过滤器了,这个项目的前台要求全部使用.html结尾,如果不修改的话,struts就会把上传的静态页面image.html当成action去处理了会报404,修改代码如下:
<filter> <filter-name>struts2</filter-name> <filter-class>com.*.*.filter.CommonFilter</filter-class> <init-param> <param-name>config</param-name> <param-value>../config/struts.xml</param-value> </init-param> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
filter的代码
public class CommonFilter extends StrutsPrepareAndExecuteFilter{ @Override public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain) throws IOException, ServletException { HttpServletRequest request = (HttpServletRequest)req; String url = request.getRequestURI(); if(url.contains("/ueditor")){ chain.doFilter(req, resp); }else{ super.doFilter(req, resp, chain); } } }
有什么问题,欢迎各位指正。
