FCKEditor编辑器的使用(一)
首先下载我们需要的JS文件和JAR包
1)：FCKeditor_2.6.4.zip
地址：http://nchc.dl.sourceforge.net/sourceforge/fckeditor/FCKeditor_2.6.4.zip
2)：fckeditor-java-2.4.1-bin.zip (JAVA支持包)地址http://nchc.dl.sourceforge.net/sourceforge/fckeditor/fckeditor-java-2.4.1-bin.zip
3)：slf4j-1.5.8.zip 地址 ：http://www.slf4j.org/dist/slf4j-1.5.8.zip
找到5个jar包：
commons-fileupload-1.2.1.jar，commons-io-1.3.2.jar，fckeditor-java-core-2.4.1.jar，slf4j-api-1.5.8.jar，slf4j-simple-1.5.8.jar将所有jar包放到lib下，将fckeditor文件夹下的所有文件复制到项目目录下。fckeditor文件夹下是需要调用的页面和js文件等等，有各种版本，需要jsp
配置
1)在工程目录src/下新建一个文件fckeditor.properties，添加内容：
connector.userFilesPath=UploadFile
connector.userActionImpl=net.fckeditor.requestcycle.impl.UserActionImpl其中第一行为重新定义上传的文件夹,默认文件夹为userfile,保存即可。
2)修改web.xml，用来提供上传功能支持
<servlet> <servlet-name>Connector</servlet-name> <servlet-class> net.fckeditor.connector.ConnectorServlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Connector</servlet-name> <url-pattern> /fckeditor/editor/filemanager/connectors/* </url-pattern> </servlet-mapping>做好上面工作可以写JSP页面:<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";String content=(String)request.getAttribute("edt1");if (content != null) {content = content.replaceAll("\r\n", "");content = content.replaceAll("\r", "");content = content.replaceAll("\n", "");content = content.replaceAll(""", "'");}else{content = "";}//下面是处理中文内容的编码转换//content = new String(content.getBytes("iso8859-1"),"utf-8");%><html><head> <base href="<%=basePath%>"> <title>FCKEditor 测试</title></head><script type="text/javascript" src="fckeditor/fckeditor.js"></script><body> <form method="post" name="frm1" action="servlet/SaveHtmlOffice"> <script type="text/javascript"> var oFCKeditor = new FCKeditor("edt1"); oFCKeditor.BasePath = "fckeditor/"; oFCKeditor.Height='400'; oFCKeditor.Value="<%=content%>"; oFCKeditor.Create(); </script> <input type="submit" value="提交"> </form> <hr> <%=content%></body></html>后台request.getParameter("edt1")获得编辑器的内容，转码到UTF-8(可以保存到数据库或html文件)上传图片时候用到的类import java.io.File;import java.io.IOException;import java.io.PrintWriter;import java.text.SimpleDateFormat;import java.util.Date;import java.util.Iterator;import java.util.List;import javax.servlet.ServletException;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.apache.commons.fileupload.FileItem;import org.apache.commons.fileupload.FileItemFactory;import org.apache.commons.fileupload.disk.DiskFileItemFactory;import org.apache.commons.fileupload.servlet.ServletFileUpload;import com.velcro.base.AbstractAction;import com.velcro.base.BaseContext;import com.velcro.base.Baseconstant;import com.velcro.base.IDGernerator;import com.velcro.base.setitem.service.SetitemService;import com.velcro.base.util.StringHelper;import com.velcro.document.base.model.Attach;import com.velcro.document.base.service.AttachService;public class UploadFileAction implements AbstractAction{public static final int SC_OK = 0;public static final int SC_ERROR = 1;public static final String ERROR_MESSAGE = "图片上传异常";public static final String IMG_SHOWURL = Baseconstant.ROOT_DIR+"/ServiceAction/com.velcro.plugin.fckeditor.DownloadFileAction";private SetitemService setitemService;private AttachService attachService;public void execute(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { this.setitemService = (SetitemService) BaseContext.getBean(request,"setitemService"); this.attachService = (AttachService) BaseContext.getBean(request,"attachService"); String action = request.getParameter("action"); if("uploadImg".equalsIgnoreCase(action)){ response.setCharacterEncoding("UTF-8"); response.setContentType("text/html; charset=UTF-8"); response.setHeader("Cache-Control", "no-cache"); PrintWriter out = response.getWriter(); String responseUrl = uploadImg(request, response); if(!StringHelper.isEmpty(responseUrl)){ out.print(responseString(SC_OK,responseUrl)); }else{ out.print(responseString(SC_ERROR, null, null, ERROR_MESSAGE)); } out.flush(); out.close(); }else if("uploadFlash".equalsIgnoreCase(action)){ uploadFlash(request, response); }}private void uploadFlash(HttpServletRequest request, HttpServletResponse response){ }/*** FCKEditor上传图片* @param request* @param response*/private String uploadImg(HttpServletRequest request, HttpServletResponse response){ FileItemFactory factory = new DiskFileItemFactory(); ServletFileUpload upload = new ServletFileUpload(factory); List uploadedItems = null; FileItem fileItem = null; Attach attach = new Attach(); String newFileName = IDGernerator.getUnquieID(); String fileRootPath = setitemService.getSetitem("402881e80b7544bb010b754c7cd8000a").getItemvalue();//服务器目录 String uploadDir = "vfiles"; SimpleDateFormat sf = new SimpleDateFormat("yyyyMM"); String date = sf.format(new Date()); char letter = (char) (Math.round((Math.random() * 100)) % 26 + (int) ('A')); String filePathName = fileRootPath + "/" + uploadDir + "/" + date + "/" + letter; File filePath = new File(filePathName); if (!filePath.exists()) { filePath.mkdirs(); } try { uploadedItems = upload.parseRequest(request); Iterator i = uploadedItems.iterator();//只支持单文件上传 while (i.hasNext()) { fileItem = (FileItem) i.next(); if (fileItem.isFormField() == false) { File uploadedFile = null; String fullFileName = fileItem.getName(); String slashType = (fullFileName.lastIndexOf("\") > 0) ?
