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

/**
 * 文件流方式读取本地图片文件（图片回显处理）
 * 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.setDateHeader("Expires", 0);
					//response.setContentType("image/jpeg");
					// 将图像输出到Servlet输出流中。

//					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();

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。
