给客户制作的项目中需要添加富文本，从网上看了一下很多人推荐kindeditor这个编辑器，用了之后也感觉不错，有一些问题的就是上传图片的时候遇到了一些问题，在这里记录一下，也方便以后查看。
首先在官网下载kindeditor压缩包，（我这里用的是kindedito-4.1.7），解压开，把jsp、 plugins、skins、kindeditor.js 、kindedditor-min.js放进自己的项目中（我是放在webroot下面新建的文件夹kindeditor下面的），其他的可以不放。
下载的压缩包中有demo我们可以参考一下，，upload_json.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><%@ page import="java.util.*,java.io.*" %><%@ page import="java.text.SimpleDateFormat" %><%@ page import="org.apache.commons.fileupload.*" %><%@ page import="org.apache.commons.fileupload.disk.*" %><%@ page import="org.apache.commons.fileupload.servlet.*" %><%@ page import="org.json.simple.*" %><%//文件保存目录路径String savePath = pageContext.getServletContext().getRealPath("/") + "attached/";//文件保存目录URLString saveUrl = request.getContextPath() + "/attached/";//定义允许上传的文件扩展名HashMap<String, String> extMap = new HashMap<String, String>();extMap.put("image", "gif,jpg,jpeg,png,bmp");extMap.put("flash", "swf,flv");extMap.put("media", "swf,flv,mp3,wav,wma,wmv,mid,avi,mpg,asf,rm,rmvb");extMap.put("file", "doc,docx,xls,xlsx,ppt,htm,html,txt,zip,rar,gz,bz2");//最大文件大小long maxSize = 1000000;response.setContentType("text/html; charset=UTF-8");if(!ServletFileUpload.isMultipartContent(request)){out.println(getError("请选择文件。"));return;}//检查目录File uploadDir = new File(savePath);if(!uploadDir.isDirectory()){out.println(getError("上传目录不存在。"));return;}//检查目录写权限if(!uploadDir.canWrite()){out.println(getError("上传目录没有写权限。"));return;}String dirName = request.getParameter("dir");if (dirName == null) {dirName = "image";}if(!extMap.containsKey(dirName)){out.println(getError("目录名不正确。"));return;}//创建文件夹savePath += dirName + "/";saveUrl += dirName + "/";File saveDirFile = new File(savePath);if (!saveDirFile.exists()) {saveDirFile.mkdirs();}SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");String ymd = sdf.format(new Date());savePath += ymd + "/";saveUrl += ymd + "/";File dirFile = new File(savePath);if (!dirFile.exists()) {dirFile.mkdirs();}FileItemFactory factory = new DiskFileItemFactory();ServletFileUpload upload = new ServletFileUpload(factory);upload.setHeaderEncoding("UTF-8");List items = upload.parseRequest(request);Iterator itr = items.iterator();while (itr.hasNext()) {FileItem item = (FileItem) itr.next();String fileName = item.getName();long fileSize = item.getSize();if (!item.isFormField()) {//检查文件大小if(item.getSize() > maxSize){out.println(getError("上传文件大小超过限制。"));return;}//检查扩展名String fileExt = fileName.substring(fileName.lastIndexOf(".") + 1).toLowerCase();if(!Arrays.<String>asList(extMap.get(dirName).split(",")).contains(fileExt)){out.println(getError("上传文件扩展名是不允许的扩展名。\n只允许" + extMap.get(dirName) + "格式。"));return;}SimpleDateFormat df = new SimpleDateFormat("yyyyMMddHHmmss");String newFileName = df.format(new Date()) + "_" + new Random().nextInt(1000) + "." + fileExt;try{File uploadedFile = new File(savePath, newFileName);item.write(uploadedFile);}catch(Exception e){out.println(getError("上传文件失败。"));return;}JSONObject obj = new JSONObject();obj.put("error", 0);obj.put("url", saveUrl + newFileName);out.println(obj.toJSONString());}}%><%!private String getError(String message) {JSONObject obj = new JSONObject();obj.put("error", 1);obj.put("message", message);return obj.toJSONString();}%>
在我们使用kindeditor的页面添加如下代码，其中item是选项卡，这里根据自己的需要添加选项。
<script charset="utf-8" src="../js/kindeditor-4.1.7/kindeditor.js"></script><script charset="utf-8" src="../js/kindeditor-4.1.7/lang/zh_CN.js"></script>KindEditor.ready(function(K) {window.editor = K.create('#editor_id', {items : ['source', '|', 'undo', 'redo', '|', 'preview', 'print', 'template', 'code', 'cut', 'copy', 'paste','plainpaste', 'wordpaste', '|', 'justifyleft', 'justifycenter', 'justifyright','justifyfull', 'insertorderedlist', 'insertunorderedlist', 'indent', 'outdent', 'subscript','superscript', 'clearhtml', 'quickformat', 'selectall', '|', 'fullscreen', '/','formatblock', 'fontname', 'fontsize', '|', 'forecolor', 'hilitecolor', 'bold','italic', 'underline', 'strikethrough', 'lineheight', 'removeformat', '|', 'image','flash', 'media', 'insertfile', 'table', 'hr', 'emoticons', 'baidumap', 'pagebreak','anchor', 'link', 'unlink', '|', 'about'],afterChange : function() {this.sync();}});});
然后修改Plugins——>image——>image.js
将其中的
uploadJson = K.undef(self.uploadJson, self.basePath + ‘php/upload_json.php’),
修改为
uploadJson = K.undef(self.uploadJson, self.basePath + ‘jsp/upload_json.jsp’),
人，总是很难改正自己的缺点，
