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;

/**

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();
	}

	@Override
	protected 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
