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)
UEditor：ueditor更注重用户体验，而且使用起来较ckeditor简单，但是ueditor在处理前后台交互时相比于ckeditor稍显麻烦
ckeditor：ckeditor不像ueditor，更多的方法需要自己去实现，但是毕竟是老牌富文本编辑器，如果之前有写过这些方法的话，集成ckeditor个人觉得还是比ueditor更方便简单。
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="/UploadFiles/2021-04-02/ckeditor.js">//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"htmlcode"><!-- FckEdit上传--> <action name="ck_upload" class="com.ccxe.wxdate.action.CkeditorUploadAction"> <param name="fileSize">5120000</param> <!-- 上传文件大小 --> </action>CkeditorUploadAction类源码

/** * 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="/UploadFiles/2021-04-02/ueditor.config.js">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。
