kindeditor 自定义上传图片

1：首先去官网下载kindeditor,我下载的是4.1的版本

由于kindeditor默认用PHP上传，我用的是JSP上传，所以得修改一下kindeditor-all-min.js文件，将上传的文件替换成upload_json.jsp

2：修改upload_json.jsp

<%
RequestDispatcher rd = getServletContext().getRequestDispatcher("/kindEditorUpload.do");
rd.forward(request, response);
JSONObject obj = new JSONObject();
%>

web.xml配置

<servlet><servlet-name>kindEditorUpload</servlet-name><servlet-class>com.kingdom.common.web.servlet.KindEditorUploadServlet</servlet-class></servlet><servlet-mapping><servlet-name>kindEditorUpload</servlet-name><url-pattern>/kindEditorUpload.do</url-pattern></servlet-mapping>

servlet转发，我上传的路径是放在远程共享文件夹里面，

package com.kingdom.common.web.servlet;import java.io.IOException;import javax.servlet.ServletConfig;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;import com.kingdom.common.web.utils.WebserviceUtils;
import com.kingdom.digitalcity.esb.webservice.soap.um.common.IUMSystemAnnexe;/*** servlet文件上传*/
public class KindEditorUploadServlet extends HttpServlet {private static final long serialVersionUID = 9207058797318727916L;private ServletContext servletContext;private IUMSystemAnnexe umSystemAnnexeService;public void init(ServletConfig config) throws ServletException {this.servletContext = config.getServletContext();}@Overrideprotected void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException {// 获取客户端回调函数名response.setContentType("text/html;charset=UTF-8");defaultProcessFileUpload(request, response);if("onerror".equals(request.getParameter("testcase")))throw new IOException();}public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {doPost(request, response);}private void defaultProcessFileUpload(HttpServletRequest request,HttpServletResponse response) throws IOException, ServletException {if(umSystemAnnexeService == null){umSystemAnnexeService = (IUMSystemAnnexe)WebserviceUtils.getBeanForServlet("umSystemAnnexeService",servletContext);}String fileDir = umSystemAnnexeService.getUMSystemAnnexeDir("upload.file.location");String showDir = umSystemAnnexeService.getUMSystemAnnexeDir("upload.show.location");request.setAttribute("fileDir",fileDir); request.setAttribute("showDir", showDir);request.getRequestDispatcher( "/common/omui/kindEditorUpload.jsp").forward(request,response);}public void setUmSystemAnnexeService(IUMSystemAnnexe umSystemAnnexeService) {this.umSystemAnnexeService = umSystemAnnexeService;}}

kindEditorUpload.jsp

uploadFileUtil是我上传文件的一个工具类

SysConfigUtil是我读取配置文件的一个工具类
