Grails中配置FCKeditor时，需要下载FCK的插件才能进行使用。
（1）创建一个web工程：grails create-app FCKDemo
（2）进入FCKDemo的目录：cd FCKDemo
（3）安装FCKeditor插件：grails install-plugin fck-editor
几分钟后安装完毕，grails会新建一个文件夹FCKDemo\plugins，在该文件夹下放置下载的插件。
（4）在FCKDemo\grails-app\conf下修改Config.groovy，在其最后添加一行：web.app.context.path=FCKDemo 因为项目的名称为FCKDemo，因此其代表web工程名称。
（5）创建一个Domain Class：grails create-domain-class Article
编辑Article.groovy文件：
   class Article {
      String title
      String content
      Date CurrentDate

      static constraints = {
          title (blank:false)
         content (blank:false,maxLength:2048)
      }
}
（6）生成Article的Controller和页面：grails generate-all Article
(7) 修改FCKDemo\grails-app\views\article中create.gsp
将：
                            <tr class="prop">
                                <td valign="top" class="name">
                                    <label for="content">Content:</label>
                                </td>
                                <td valign="top" class="value ${hasErrors(bean:article,field:'content','errors')}">
                                    <input type="text" id="content" name="content" value="${fieldValue(bean:article,field:'content')}"/>
                                </td>
                            </tr>
改为：
                            <tr class="prop">
                                <td valign="top" class="name">
                                    <label for="content">Content:</label>
                                </td>
                                <td valign="top" class="value ${hasErrors(bean:article,field:'content','errors')}">
                                    <fck:editor id='content' name='content' height="400" >${article.content}</fck:editor>
                                </td>
                            </tr>

修改FCKDemo\grails-app\views\article中editor.gsp
将：
                            <tr class="prop">
                                <td valign="top" class="name">
                                    <label for="content">Content:</label>
                                </td>
                                <td valign="top" class="value ${hasErrors(bean:article,field:'content','errors')}">
                                    <input type="text" id="content" name="content" value="${fieldValue(bean:article,field:'content')}"/>
                                </td>
                            </tr>
改为：
                            <tr class="prop">
                                <td valign="top" class="name">
                                    <label for="content">Content:</label>
                                </td>
                                <td valign="top" class="value ${hasErrors(bean:article,field:'content','errors')}">
                                    <fck:editor id='content' name='content' height="400" >${article.content}</fck:editor>
                                </td>
                            </tr>

（8）部署web工程：grails run-app
在浏览器下输入：http://localhost:8080/FCKDemo

测试创建一个article的页面

编辑该页面

Update后的结果
