准备工作 先把这两个东西加入项目，导相应的包，注意的是ckfinder的文件是官网上下载的ckfinder_java_2.1.1.jar解压后ckfinder/ckfinder.war(解压)/ckfinder这个文件夹 而不是直接解压出来见到的那个，是war的那个，这点搞了我半天。导的jar包路径： ckfinder_java_2.1.1\ckfinder\WEB-INF\lib；C:\Users\Administrator\Desktop\ckfinder_java_2.1.1\ckeditor\WEB-INF\lib
下面是需要显示的jsp关键代码：
<script type="text/javascript" src="user/ckeditor/ckeditor.js" ></script> <script type="text/javascript" src="user/ckfinder/ckfinder.js" ></script> //上面的代码在head里 下面的在body <textarea cols="80" id="content" name="content" rows="20">这里是默认值</textarea> <script type="text/javascript"> var editor=CKEDITOR.replace("content"); CKFinder.SetupCKEditor(editor,'ckfinder/'); </script>注意上面的细节，要不你的结局将和我一样 因为双引号和单引号搞一晚上，第一个 replace方法里的参数的textarea里的name属性，双引号
而后面的SetCKEditor这方法是用来设置ckfinder这文件夹处理上传这功能的，一个字母都不能错哦。
ckeditor这文件夹下的config.js是用来配置这编辑器的，代码如下：
CKEDITOR.editorConfig = function( config ) { // Define changes to default configuration here. For example: // config.language = 'fr'; // config.uiColor = '#AADC6E'; config.language = 'zh-cn'; //设置中文语言 config.uiColor = '#AADC6E'; //编辑器颜色 config.font_names = '宋体;楷体_GB2312;新宋体;黑体;隶书;幼圆;微软雅黑;Arial;Comic Sans MS;Courier New;Tahoma;Times New Roman;Verdana'; config.toolbar_Full = [ [ 'Source', '-', 'Preview', '-', 'Templates' ], [ 'Cut', 'Copy', 'Paste', 'PasteText', 'PasteFromWord', '-', 'Print', 'SpellChecker', 'Scayt' ], [ 'Undo', 'Redo', '-', 'Find', 'Replace', '-', 'SelectAll', 'RemoveFormat' ], [ 'Form', 'Checkbox', 'Radio', 'TextField', 'Textarea', 'Select', 'Button', 'ImageButton', 'HiddenField' ], '/', [ 'Bold', 'Italic', 'Underline', 'Strike', '-', 'Subscript', 'Superscript' ], [ 'NumberedList', 'BulletedList', '-', 'Outdent', 'Indent', 'Blockquote', 'CreateDiv' ], [ 'JustifyLeft', 'JustifyCenter', 'JustifyRight', 'JustifyBlock' ], [ 'Link', 'Unlink', 'Anchor' ], [ 'Image', 'Flash', 'Table', 'HorizontalRule', 'Smiley', 'SpecialChar', 'PageBreak' ], '/', [ 'Styles', 'Format', 'Font', 'FontSize' ], [ 'TextColor', 'BGColor' ], [ 'Maximize', 'ShowBlocks', '-', 'About' ] ]; config.toolbar_Basic = [ [ 'Bold', 'Italic', '-', 'NumberedList', 'BulletedList', '-', 'Link', 'Unlink', '-', 'About' ] ]; config.width = 700; config.height = 300; config.filebrowserBrowseUrl = 'user/ckfinder/ckfinder.html'; //上传文件时浏览服务文件夹 config.filebrowserImageBrowseUrl = 'user/ckfinder/ckfinder.html?Type=Images'; //上传图片时浏览服务文件夹 config.filebrowserFlashBrowseUrl = 'user/ckfinder/ckfinder.html?Type=Flash'; //上传Flash时浏览服务文件夹 config.filebrowserUploadUrl = 'user/ckfinder/core/connector/aspx/connector.aspx?command=QuickUpload&type=Files'; //上传文件按钮(标签) config.filebrowserImageUploadUrl = 'user/ckfinder/core/connector/aspx/connector.aspx?command=QuickUpload&type=Images'; //上传图片按钮(标签) config.filebrowserFlashUploadUrl = 'user/ckfinder/core/connector/aspx/connector.aspx?command=QuickUpload&type=Flash'; //上传Flash按钮(标签) };这里大家需要注意的是路径问题，尤其是最后那些url，注意的是单引号后没有/，因为在项目里，已经自动的加上了/，我见网上很多代码都是带/，经我测试都是404，
我这里是把ckeditor，ckfinder这两个文件夹放在user文件夹下面，如果你直接放根路径，去掉user/即可，注意不要以/开始。
下面是web.xml,配置，这里为了方便，我把代码全放上了，里面配了自定义的拦截器，这个最后再说。

另外上那自定义的拦截器，继承struts2默认的拦截器，这样就在上面的web.xml中用这拦截器拦截请求，好处就是按照自己的需求拦截public class FCKFilter extends StrutsPrepareAndExecuteFilter { public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException { HttpServletRequest request = (HttpServletRequest) req; String URI = request.getRequestURI(); String[] uriArray = URI.split("/ckfinder/core/connector/java/*/"); int arrayLen = uriArray.length; if (arrayLen >= 2) { chain.doFilter(req, res); } else { super.doFilter(req, res, chain); } } }CKEditor是使用servlet来实现的,它也是通过拦截URL的机制进行工作的,而strutes2的拦截器咱一般配置<filter-name>struts2</filter-name><url-pattern>/*</url-pattern> struts2会拦截所有以"/"开头的URL.所以ckeditor的编辑器就被strut2拦截了这也是今天晚上困扰我的问题，一直点浏览服务器，虽然出现files，images，falsh这几个文件夹，但是点上传后出现红色的叹号，后来突然醒悟，原来是struts2拦截了！！所以重写拦截器的目的也就是不让struts2拦截ckfinder的servlet，所以要分割url字符串，假如是ckeditor，那么split（/ckfinder/..）后就能至少分2段，这样就直接转发，不拦截。ckfinder这插件是用来处理ckeditor上传下载的功能的图片暂时上不来 不知道为什么一直显示图片不正常
