HTML编辑器FCKeditor使用详解

本文介绍FCKeditor在Java环境下的使用方法。

一、简介

功能：所见即所得，支持图片和Flash，工具栏可自由配置，使用简单
兼容性：IE 5.5+、Firefox 1.5+、Safari 3.0+、Opera 9.50+、Netscape 7.1+、 Camino 1.0+
成熟度：使用广泛，被Baidu、CSDN等选用

二、下载

官方下载首页：http://www.fckeditor.net/download/，当前版本为2.5.1
需要下载FCKeditor 2.5.1（FCKeditor_2.5.1.zip）和FCKeditor.Java（FCKeditor-2.3.zip）

三、部署

本例以WebRoot作为应用根路径，部署后的目录结构如下图所示：

1、FCKeditor_2.5.1.zip解压，将fckeditor文件夹复制到/WebRoot/下

2、FCKeditor-2.3.zip解压，将commons-fileupload.jar和FCKeditor-2.3.jar复制到/WebRoot/WEB-INF/lib/下 

3、修改/WebRoot/WEB-INF/web.xml文件，增加以下内容：             

<servlet>
<servlet-name>Connector</servlet-name>
        <servlet-class>com.fredck.FCKeditor.connector.ConnectorServlet</servlet-class>
        <init-param>
            <param-name>baseDir</param-name>
            <param-value>/UserFiles/</param-value>
        </init-param>
        <init-param>
            <param-name>debug</param-name>
            <param-value>true</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet>
        <servlet-name>SimpleUploader</servlet-name>
        <servlet-class>com.fredck.FCKeditor.uploader.SimpleUploaderServlet</servlet-class>
        <init-param>
            <param-name>baseDir</param-name>
            <param-value>/UserFiles/</param-value>
        </init-param>
        <init-param>
            <param-name>debug</param-name>
            <param-value>true</param-value>
        </init-param>
        <init-param>
            <param-name>enabled</param-name>
            <param-value>true</param-value>
        </init-param>
        <init-param>
            <param-name>AllowedExtensionsFile</param-name>
            <param-value></param-value>
        </init-param>
        <init-param>
            <param-name>DeniedExtensionsFile</param-name>
            <param-value>php|php3|php5|phtml|asp|aspx|ascx|jsp|cfm|cfc|pl|bat|exe|dll|reg|cgi</param-value>
        </init-param>
        <init-param>
            <param-name>AllowedExtensionsImage</param-name>
            <param-value>jpg|gif|jpeg|png|bmp</param-value>
        </init-param>
        <init-param>
            <param-name>DeniedExtensionsImage</param-name>
            <param-value></param-value>
        </init-param>
        <init-param>
            <param-name>AllowedExtensionsFlash</param-name>
            <param-value>swf|fla</param-value>
        </init-param>
        <init-param>
            <param-name>DeniedExtensionsFlash</param-name>
            <param-value></param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

  <servlet-mapping>
    <servlet-name>Connector</servlet-name>
    <url-pattern>/fckeditor/connector</url-pattern>
  </servlet-mapping>
  
  <servlet-mapping>
    <servlet-name>SimpleUploader</servlet-name>
    <url-pattern>/fckeditor/simpleuploader</url-pattern>
  </servlet-mapping>

 4、修改/WebRoot/fckeditor/fckconfig.js，修改部分如下：

FCKConfig.LinkBrowserURL = FCKConfig.BasePath + 'filemanager/browser/default/browser.html?Connector=/fckeditor/connector' ;
FCKConfig.ImageBrowserURL = FCKConfig.BasePath + 'filemanager/browser/default/browser.html?Type=Image&Connector=/fckeditor/connector' ;
FCKConfig.FlashBrowserURL = FCKConfig.BasePath + 'filemanager/browser/default/browser.html?Type=Flash&Connector=/fckeditor/connector' ;
FCKConfig.LinkUploadURL = '/fckeditor/simpleuploader?Type=File' ;
FCKConfig.ImageUploadURL = '/fckeditor/simpleuploader?Type=Image' ;
FCKConfig.FlashUploadURL = '/fckeditor/simpleuploader?Type=Flash';

注意：
(1) 步骤3、4设置了文件浏览和上传的配置，web.xml中Servlet的<url-pattern>要和fckconfig.js中的URL引用一致；
(2) 本例正常运行的前提是WebRoot被部署为根路径，如果设了虚拟路径会找不到servlet。
