今天学会了如何自己编写 JSP 用来处理 CKEditor 的图片上传。

<%@ page import="org.apache.commons.fileupload.FileItem" %><br /> <%@ page import="java.util.List" %><br /> <%@ page import="org.apache.commons.fileupload.disk.DiskFileItemFactory" %><br /> <%@ page import="org.apache.commons.fileupload.servlet.ServletFileUpload" %><br /> <%@ page import="org.apache.commons.io.FilenameUtils" %><br /> <%@ page import="java.io.File" %><br /> <%@ page import="org.apache.commons.lang.StringUtils" %><br /> <%@ page contentType="text/html;charset=UTF-8" language="java" %><br /> <%<br /> String callback = request.getParameter("CKEditorFuncNum");</p> <p> try {<br /> if (ServletFileUpload.isMultipartContent(request)) {<br /> ServletFileUpload servletFileUpload = new ServletFileUpload(new DiskFileItemFactory());<br /> List<FileItem> fileItemsList = servletFileUpload.parseRequest(request);</p> <p> String filename = String.valueOf(System.currentTimeMillis());<br /> for (FileItem item : fileItemsList) {<br /> if (!item.isFormField()) {<br /> String _filename = item.getName();<br /> filename += "." + FilenameUtils.getExtension(_filename);</p> <p> String clientPath = "images/" + filename; // 这里应根据需要修改。</p> <p> File file = new File(application.getRealPath(clientPath));<br /> if (!file.getParentFile().exists()) {<br /> file.getParentFile().mkdirs();<br /> }<br /> item.write(file);<br /> }<br /> }<br /> %><br /> <mce:script type="text/javascript"><!--<br /> window.parent.CKEDITOR.tools.callFunction(<%=callback%>, '<%=clientPath%>', '');<br /> // --></mce:script><br /> <%<br /> }<br /> } catch (Exception e) {<br /> e.printStackTrace();<br /> %>文件上传失败。<%<br /> }<br /> %>

这里一个很重要的参数就是 CKEditorFuncNum，它是上传成功后进行回调的一个必要参数。
