kindeditor的简单使用
上传到云：
一、引入kindeditor
<%@ page language="java" contentType="text/html; charset=UTF-8"%>
<%@ include file="/WEB-INF/views/commons/taglibs.jsp"%>
<html>
<head>
<script type="text/javascript"> yepnope({
load:[
'${ctx}/resources/kindeditor/themes/default/default.css',
'${ctx}/resources/kindeditor/plugins/code/prettify.css',
'${ctx}/resources/js/ux/KindEditor.js',
'${ctx}/resources/kindeditor/kindeditor.js',
'${ctx}/resources/kindeditor/lang/zh_CN.js',
'${ctx}/resources/kindeditor/plugins/code/prettify.js',
'${ctx}/resources/extjs/ux/combotree/ComboTree.js',
'${ctx}/resources/extjs/ux/css/Spinner.css',
'${ctx}/resources/extjs/ux/Spinner.js',
'${ctx}/resources/extjs/ux/SpinnerField.js',
'${ctx}/resources/extjs/ux/DateTimeField.js',
'${ctx}/plugins/websites/web/resources/js/news/NewsFormPanel.js',
'${ctx}/plugins/websites/web/resources/js/news/NewsFormWin.js',
'${ctx}/plugins/websites/web/resources/js/news/NewsReadWindow.js',
'${ctx}/plugins/websites/web/resources/js/news/NewsUploadWindow.js',

'${ctx}/plugins/websites/web/resources/js/news/TreeWindow.js',
'${ctx}/resources/js/shareux.js',
'${ctx}/resources/js/ux/StarHtmleditor.js'],
complete:function(){ var panel = new Ext.websites.NewsPanel({
height : index.tabPanel.getInnerHeight() - 1,
id: '${param.id}' + '_panel',
actionJson:${actionJson},
renderTo: '${param.id}'
});
}
});
</script>
</head>
<body>
<div id="${param.id}"></div>
</body>
</html>
二、重写下kindeditor方法
Ext.ux.KindEditor = Ext.extend(Ext.form.TextArea, {
uploadUrl:null,
render : function(editor) {
Ext.ux.KindEditor.superclass.render.call(this, editor);
var contentId = this.id;
if(this.uploadUrl == undefined){
this.uploadUrl = 'kindEditor/upload';
}
var that = this;
window.setTimeout(function() {
that.myEditor = KindEditor.create('#' + contentId, {
cssPath : 'resources/kindeditor/plugins/code/prettify.css',
uploadJson : that.uploadUrl,
// uploadJson:'resources/kindeditor/jsp/upload_json.jsp',
fileManagerJson : 'resources/kindeditor/jsp/file_manager_json.jsp',
resizeType : 1,
resizeMode : 1,
filterMode : false,
allowFileManager : true,
afterCreate : function(id) {
/* 响应 ctrl + v ，保存图片* */
//KindEditor.ctrl(document, 'v', function() {
// });
// KindEditor.ctrl(KindEditor.g[id].iframeDoc, 86, function() {
// KindEditor.util.setData(id);
// var doc = KindEditor.g[id].iframeDoc;
// setTimeout(dealdoc(doc), 100);
// });
// // ie 中粘贴 --- 包括 toolbar 中 的粘贴和右键浏览器菜单中的粘贴
// KindEditor.g[id].iframeDoc.body.onpaste = function() {
// var doc = KindEditor.g[id].iframeDoc;
// setTimeout(dealdoc(doc), 100);
// };
// // firefox 粘贴 --- 包括 ctrl+v 和右键浏览器菜单中的粘贴
// $(KindEditor.g[id].iframeDoc).bind('paste', null, function() {
// var doc = KindEditor.g[id].iframeDoc;
// setTimeout(dealdoc(doc), 100);
// });
}
});
}, 500);
},
getValue : function() {
if (this.myEditor) {
return this.myEditor.html();
} else {
return '';
}
},
setValue : function(v) {
var contentId = this.id;
var that = this;
window.setTimeout(function() {
KindEditor.html('#' + contentId, v);
}, 500);
}
});
// 返回 一个无参的方法，用于setTimeout
function dealdoc(doc) {
return function() {
deal(doc);
}
}
// 粘贴时处理图片-- 方法二：同步，可以接受多张图片
function deal(doc) {
var links = doc.getElementsByTagName("img");
for (var i = 0; i < links.length; i++) {
var lin = $(links[i]);
if ($(lin).attr("add_src")) {
} else {
// links[i].src = "<c:url
// value='/saveImageServlet?mageurl='/>"+links[i].src;
var imgurl = $(lin).attr("src");
var html = $.ajax({
type : "POST",
url : "<c:url value='/saveImageServlet'/>",
data : "imageurl=" + imgurl,
dataType : "html",
async : false
}).responseText;
$(lin).attr("src", "");
$(lin).attr("src", html);
$(lin).attr("add_src", "1");
}
}
}
Ext.reg('kindeditor', Ext.ux.KindEditor);
这个是上面引入的ux包下的kindeditor方法
三、kindeditor上传的controller
package cn.edu.hbcf.privilege.web.controller; import java.io.PrintWriter;
import java.util.Arrays;
import java.util.HashMap;
import java.util.Map;
import java.util.UUID; import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse; import org.apache.commons.lang.StringUtils;
import org.json.simple.JSONObject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.multipart.MultipartFile; import cn.edu.hbcf.common.hadoop.FileManager;
import cn.edu.hbcf.common.hadoop.FileSysFactory;
import cn.edu.hbcf.common.hadoop.FileSysType; @Controller
@RequestMapping("/kindEditor")
public class KindeditorController { @RequestMapping("/upload")
public void upload(@RequestParam
MultipartFile imgFile, HttpServletRequest request, String dir,
HttpServletResponse response) {
try {
// 定义允许上传的文件扩展名
response.setContentType("text/html; charset=UTF-8");
PrintWriter out = response.getWriter();
Map<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"); String fileName = imgFile.getOriginalFilename();
// 检查扩展名
String fileExt = StringUtils.substringAfterLast(fileName, ".").toLowerCase();
if (!Arrays.<String> asList(extMap.get(dir).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(dir)
+ "格式。"));
return;
} // 获取文件后缀名
String saveName = UUID.randomUUID().toString().replace("-", "")+("".equals(fileExt) ? "" : "." + fileExt);
String filePath="/filesharesystem/attach";
FileManager fileMgr=FileSysFactory.getInstance(FileSysType.HDFS);
fileMgr.putFile(imgFile.getInputStream(), filePath, saveName); //
JSONObject obj = new JSONObject();
obj.put("error", 0);
if("image".equals(dir)||"media".equals(dir)||"flash".equals(dir)){
obj.put("url", "dfs/queryResource?resourcePath="+filePath+"/"+saveName);
}else{
obj.put("url", "dfs/downloadFile?filePath="+filePath+"/"+saveName+"&fileName="+fileName);
}
System.out.println("AAAAAAAAAURL:"+obj.get("url"));
out.println(obj.toJSONString());
} catch (Exception e) {
e.printStackTrace(); } } private String getError(String message) {
JSONObject obj = new JSONObject();
obj.put("error", 1);
obj.put("message", message);
return obj.toJSONString();
} }
四、根据地址预览、下载文件的方法
