我要评论ckeditor和ueditor使用比较
本来项目中使用ckeditor已经做好了的富文本编辑器的功能，但是业务考虑到美观性要求换成ueditor，所以就在这里总结下
先说下使用这两个不同插件的感想，我用的ueditor是1.4.3的版本：(ueditor api)
ueditor：ueditor更注重用户体验，而且使用起来较ckeditor简单，但是ueditor在处理前后台交互时相比于ckeditor稍显麻烦
ckeditor：ckeditor不像ueditor，更多的方法需要自己去实现，但是毕竟是老牌富文本编辑器，如果之前有写过这些方法的话，集成ckeditor个人觉得还是比ueditor更方便简单。
ckeditor的使用
在jsp页面下引入ckeditor下的ckeditor.js（当然首先要引入jquery.js,引入插件类库ckeditor-java-core-3.5.3.jar）
<script type="text/javascript" src="${basepath}/js/ckeditor/ckeditor.js"></script>
//引入js后在textarea标签上添加一个richtext=”true”这个属性即可
<textarea name="wxchoiceinfo.infotextconte" id="wxchoiceinfoinfotextconte" richtext="true" cols="110" rows="15"></textarea>
获取ckeditor中的内容
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
});
});
});
action配置
<!-- fckedit上传--> <action name="ck_upload" class="com.ccxe.wxdate.action.ckeditoruploadaction"> <param name="filesize">5120000</param> <!-- 上传文件大小 --> </action>

图片回显到编辑器的servlet代码
/**

*/
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 {
//得到文件名称
string imagename = request.getparameter("imagename");
string foldtype = request.getparameter("fold");
string imagepath = "";
//imagepath路径的设置
webapplicationcontext wac = contextloader.getcurrentwebapplicationcontext();
wxconfig wxconfig = (wxconfig)wac.getbean("wxconfig");//模块配置文件
//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); //扩展名
//得到配置文件路径
string imagedir = imagepath+"/"+imagename; //文件全局路径
file inputfile = new file(imagedir);
if (inputfile.exists()) {
//bufferedimage input = imageio.read(inputfile);
// 禁止图像缓存。
response.setheader("pragma", "no-cache");
response.setheader("cache-control", "no-cache");

//response.setcontenttype("image/jpeg");
// 将图像输出到servlet输出流中。
// servletoutputstream sos = response.getoutputstream();
// imageio.write(input, imageext, sos);
// sos.flush();
// sos.close();
inputstream in = new fileinputstream(inputfile);
outputstream os = response.getoutputstream(); //创建输出流
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>
再来看ueditor：
//引入相关的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="${basepath}/js/ueditor/themes/default/css/ueditor.css" rel="external nofollow" >
jsp页面部分代码：
<form action="<s:url value="/p2p/updateiproductservices.action"/>" method="post" id="form">
<tr id="proinvsertr">
<th>投资服务流程 <input type="hidden" id="hidinvestprocess" name="productservices.investserprocess"/></th>
<td>
<!-- 加载编辑器的容器 -->
<script id="container" name="content" type="text/plain">${productservices.investserprocess}</script>
<!-- 实例化编辑器 -->
<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();
}
说了那么多，那使用ueditor怎么修改文件上次的路劲呢，在1.4.3版本下，找到ueditor\jsp\config.json文件
找到上次图片配置项的"imageurlprefix": "/", /* 图片访问路径前缀 */ "imagepathformat": "upload/image/{yyyy}{mm}{dd}/{time}{rand:6}" //这里是我改过了的上传路径
注意要修改imageurlprefix，因为编辑器中图片显示路径是imageurlprefix+imagepathformat，如果不修改imageurlprefix图片是不能正常显示的，imagepathformat这个上传路径是相对于服务器的相对路径。
使用ueditor最主要的就是需要修改web.xml中得struts的过滤器了，这个项目的前台要求全部使用.html结尾，如果不修改的话，struts就会把上传的静态页面image.html当成action去处理了会报404，修改代码如下：
<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的代码
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);
}
}
}
有什么问题，欢迎各位指正。
