CKEditor和UEditor使用比較
本來項目中使用CKEditor已經做好了的富文本編輯器的功能，但是業務考慮到美觀性要求換成UEditor，所以就在這里總結下
先說下使用這兩個不同插件的感想，我用的ueditor是1.4.3的版本：(ueditor API)
UEditor：ueditor更注重用戶體驗，而且使用起來較ckeditor簡單，但是ueditor在處理前后臺交互時相比于ckeditor稍顯麻煩
ckeditor：ckeditor不像ueditor，更多的方法需要自己去實現，但是畢竟是老牌富文本編輯器，如果之前有寫過這些方法的話，集成ckeditor個人覺得還是比ueditor更方便簡單。
CKEditor的使用
在jsp頁面下引入ckeditor下的ckeditor.js（當然首先要引入jQuery.js,引入插件類庫ckeditor-Java-core-3.5.3.jar）
script type="text/javascript" src="${basePath}/js/ckeditor/ckeditor.js">/script>
//引入js后在textarea標簽上添加一個richText=”true”這個屬性即可
textarea name="wxChoiceInfo.infoTextConte" id="wxChoiceInfoInfoTextConte" richText="true" cols="110" rows="15">/textarea>
獲取ckeditor中的內容
Var content = CKEDITOR.instances.wxChoiceInfoInfoTextConte.getData(content);
//初始化
$(function() {
//富文本字段初始化
$("[richText]").each(function (e) {
CKEDITOR.replace($(this).attr("id"),{
height : 400,
skin : 'kama',
language : 'zh-cn',
filebrowserImageUploadUrl:'${basePath}/wxdate/ck_upload.action?fileType=1',
toolbar: 'ToolbarCommon',
resize_enabled: false
});
});
});

圖片回顯到編輯器的servlet代碼
/**
* 文件流方式讀取本地圖片文件（圖片回顯處理）
* FckImageReaderServlet
*/
public class FckImageReaderServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
public void init() throws ServletException {
}
public void doGet(HttpServletRequest request, HttpServletResponse response) {
this.doPost(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response) {
try {
//得到文件名稱
String imageName = request.getParameter("imageName");
String foldType = request.getParameter("fold");
String imagePath = "";
//imagePath路徑的設置
WebApplicationContext wac = ContextLoader.getCurrentWebApplicationContext();
WxConfig wxConfig = (WxConfig)wac.getBean("wxConfig");//模塊配置文件
//if(fileType.equals(PubParaConstants.DC_CK_UPLOAD_PATTH_PARAM.DC_CK_UPLOAD_PATTH_PARAM_PROSELECT)) {
imagePath = wxConfig.getFilePath();
//}
if (imageName != null) {
String imageExt = imageName.substring(imageName.lastIndexOf(".") + 1); //擴展名
//得到配置文件路徑
String imageDir = imagePath+"/"+imageName; //文件全局路徑
File inputFile = new File(imageDir);
if (inputFile.exists()) {
//BufferedImage input = ImageIO.read(inputFile);
// 禁止圖像緩存。
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);
//response.setContentType("image/jpeg");
// 將圖像輸出到Servlet輸出流中。
// ServletOutputStream sos = response.getOutputStream();
// ImageIO.write(input, imageExt, sos);
// sos.flush();
// sos.close();
InputStream in = new FileInputStream(inputFile);
OutputStream os = response.getOutputStream(); //創建輸出流
byte[] b = new byte[1024];
while( in.read(b)!= -1){
os.write(b);
}
in.close();
os.flush();
os.close();
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
web.xml
Web.xml配置FckImageReaderServlet
!-- FCK -->
servlet>
servlet-name>FckReader/servlet-name>
servlet-class>com.***.common.file.FckImageReaderServlet/servlet-class>
/servlet>
servlet-mapping>
servlet-name>FckReader/servlet-name>
url-pattern>/fckImageReader.servlet/url-pattern>
/servlet-mapping>
再來看UEditor：
//引入相關的js和css
script type="text/javascript" src="${basePath}/js/ueditor/ueditor.config.js">/script>
script type="text/javascript" src="${basePath}/js/ueditor/ueditor.all.js">/script>
link type="text/css" rel="stylesheet" href="${basePath}/js/ueditor/themes/default/css/ueditor.css" rel="external nofollow" >
jsp頁面部分代碼：
form action="s:url value="/p2p/updateIProductServices.action"/>" method="post" id="form">
tr id="proInvSerTr">
th>投資服務流程 input type="hidden" id="hidInvestProcess" name="productServices.investSerProcess"/>/th>
td>
!-- 加載編輯器的容器 -->
script id="container" name="content" type="text/plain">${productServices.investSerProcess}/script>
!-- 實例化編輯器 -->
script type="text/javascript">
var ue = UE.getEditor('container');
/script>
/td>
/tr>
input type="button" value="保存" class="ImgButton" onclick="submitForm"/>
/form>
script type="text/javascript">
function submitForm(){
$("#hidInvestProcess").val(ue.getContent());
$("#form").submit();
}
說了那么多，那使用ueditor怎么修改文件上次的路勁呢，在1.4.3版本下，找到ueditor\jsp\config.json文件
找到上次圖片配置項的"imageUrlPrefix": "/", /* 圖片訪問路徑前綴 */ "imagePathFormat": "upload/image/{yyyy}{mm}{dd}/{time}{rand:6}" //這里是我改過了的上傳路徑
注意要修改imageUrlPrefix，因為編輯器中圖片顯示路徑是imageUrlPrefix+imagePathFormat，如果不修改imageUrlPrefix圖片是不能正常顯示的，imagePathFormat這個上傳路徑是相對于服務器的相對路徑。
使用ueditor最主要的就是需要修改web.xml中得struts的過濾器了，這個項目的前臺要求全部使用.html結尾，如果不修改的話，struts就會把上傳的靜態頁面image.html當成action去處理了會報404，修改代碼如下：
filter>
filter-name>struts2/filter-name>
filter-class>com.***.***.filter.CommonFilter/filter-class>
init-param>
param-name>config/param-name>
param-value>../config/struts.xml/param-value>
/init-param>
/filter>
filter-mapping>
filter-name>struts2/filter-name>
url-pattern>/*/url-pattern>
/filter-mapping>
filter的代碼
public class CommonFilter extends StrutsPrepareAndExecuteFilter{
@Override
public void doFilter(ServletRequest req, ServletResponse resp,
FilterChain chain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest)req;
String url = request.getRequestURI();
if(url.contains("/ueditor")){
chain.doFilter(req, resp);
}else{
super.doFilter(req, resp, chain);
}
}
}
有什么問題，歡迎各位指正。
