準備工作 先把這兩個東西加入項目，導相應的包，注意的是ckfinder的文件是官網上下載的ckfinder_java_2.1.1.jar解壓後ckfinder/ckfinder.war(解壓)/ckfinder這個文件夾 而不是直接解壓出來見到的那個，是war的那個，這點搞了我半天。導的jar包路徑： ckfinder_java_2.1.1\ckfinder\WEB-INF\lib；C:\Users\Administrator\Desktop\ckfinder_java_2.1.1\ckeditor\WEB-INF\lib
下面是需要顯示的jsp關鍵代碼：
<script type="text/javascript" src="user/ckeditor/ckeditor.js" ></script>
<script type="text/javascript" src="user/ckfinder/ckfinder.js" ></script>
//上面的代碼在head裏 下面的在body
<textarea cols="80" id="content" name="content" rows="20">這裏是默認值</textarea>
<script type="text/javascript">
var editor=CKEDITOR.replace("content");
CKFinder.SetupCKEditor(editor,'ckfinder/');
</script>注意上面的細節，要不你的結局將和我一樣 因爲雙引號和單引號搞一晚上，第一個 replace方法裏的參數的textarea裏的name屬性，雙引號
而後面的SetCKEditor這方法是用來設置ckfinder這文件夾處理上傳這功能的，一個字母都不能錯哦。
ckeditor這文件夾下的config.js是用來配置這編輯器的，代碼如下：
CKEDITOR.editorConfig = function( config )
{
// Define changes to default configuration here. For example:
// config.language = 'fr';
// config.uiColor = '#AADC6E';
config.language = 'zh-cn'; //設置中文語言
config.uiColor = '#AADC6E'; //編輯器顏色
config.font_names = '宋體;楷體_GB2312;新宋體;黑體;隸書;幼圓;微軟雅黑;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'; //上傳文件時瀏覽服務文件夾
config.filebrowserImageBrowseUrl = 'user/ckfinder/ckfinder.html?Type=Images'; //上傳圖片時瀏覽服務文件夾
config.filebrowserFlashBrowseUrl = 'user/ckfinder/ckfinder.html?Type=Flash'; //上傳Flash時瀏覽服務文件夾
config.filebrowserUploadUrl = 'user/ckfinder/core/connector/aspx/connector.aspx?command=QuickUpload&type=Files'; //上傳文件按鈕(標籤)
config.filebrowserImageUploadUrl = 'user/ckfinder/core/connector/aspx/connector.aspx?command=QuickUpload&type=Images'; //上傳圖片按鈕(標籤)
config.filebrowserFlashUploadUrl = 'user/ckfinder/core/connector/aspx/connector.aspx?command=QuickUpload&type=Flash'; //上傳Flash按鈕(標籤)
};
這裏大家需要注意的是路徑問題，尤其是最後那些url，注意的是單引號後沒有/，因爲在項目裏，已經自動的加上了/，我見網上很多代碼都是帶/，經我測試都是404，
我這裏是把ckeditor，ckfinder這兩個文件夾放在user文件夾下面，如果你直接放根路徑，去掉user/即可，注意不要以/開始。
下面是web.xml,配置，這裏爲了方便，我把代碼全放上了，裏面配了自定義的攔截器，這個最後再說。

FCKFilter這類是自定義的攔截器，上面的配置中還寫明瞭從/WEB-INFO/ckfinder-config.xml中加載配置，這個名字可以隨意起，只要系統能找到就行。ckfinder-config.xml：
<config> <enabled>true</enabled> <baseDir></baseDir> <baseURL>MyBlog/userfiles</baseURL> <licenseKey></licenseKey> <licenseName></licenseName> <imgWidth>1600</imgWidth> <imgHeight>1200</imgHeight> <imgQuality>80</imgQuality> <uriEncoding>UTF-8</uriEncoding> <forceASCII>false</forceASCII> <userRoleSessionVar>CKFinder_UserRole</userRoleSessionVar> <checkDoubleExtension>true</checkDoubleExtension> <checkSizeAfterScaling>true</checkSizeAfterScaling> <secureImageUploads>true</secureImageUploads> <htmlExtensions>html,htm,xml,js</htmlExtensions> <hideFolders> <folder>.svn</folder> <folder>CVS</folder> </hideFolders> <hideFiles> <file>.*</file> </hideFiles> <defaultResourceTypes></defaultResourceTypes> <types> <type name="Files"> <url>%BASE_URL%files/</url> <directory>%BASE_DIR%files</directory> <maxSize>10m</maxSize> <allowedExtensions>7z,aiff,asf,avi,bmp,csv,doc,docx,fla,flv,gif,gz,gzip,jpeg,jpg,mid,mov,mp3,mp4,mpc,mpeg,mpg,ods,odt,pdf,png,ppt,pptx,pxd,qt,ram,rar,rm,rmi,rmvb,rtf,sdc,sitd,swf,sxc,sxw,tar,tgz,tif,tiff,txt,vsd,wav,wma,wmv,xls,xlsx,zip </allowedExtensions> <deniedExtensions></deniedExtensions> </type> <type name="Images"> <url>%BASE_URL%images/</url> <directory>%BASE_DIR%images</directory> <maxSize>2m</maxSize> <allowedExtensions>bmp,gif,jpeg,jpg,png</allowedExtensions> <deniedExtensions></deniedExtensions> </type> <type name="Flash"> <url>%BASE_URL%flash/</url> <directory>%BASE_DIR%flash</directory> <maxSize>20m</maxSize> <allowedExtensions>swf,flv</allowedExtensions> <deniedExtensions></deniedExtensions> </type> </types> <accessControls> <accessControl> <role>*</role> <resourceType>*</resourceType> <folder>/</folder> <folderView>true</folderView> <folderCreate>true</folderCreate> <folderRename>false</folderRename> <folderDelete>false</folderDelete> <fileView>true</fileView> <fileUpload>true</fileUpload> <fileRename>false</fileRename> <fileDelete>false</fileDelete> </accessControl> </accessControls> <thumbs> <enabled>true</enabled> <url>%BASE_URL%_thumbs/</url> <directory>%BASE_DIR%_thumbs</directory> <directAccess>false</directAccess> <maxHeight>100</maxHeight> <maxWidth>100</maxWidth> <quality>80</quality> </thumbs> <plugins> <plugin> <name>imageresize</name> <class>com.ckfinder.connector.plugins.ImageResize</class> <params> <param name="smallThumb" value="90x90"></param> <param name="mediumThumb" value="120x120"></param> <param name="largeThumb" value="180x180"></param> </params> </plugin> <plugin> <name>fileeditor</name> <class>com.ckfinder.connector.plugins.FileEditor</class> <params></params> </plugin> </plugins> <basePathBuilderImpl>com.ckfinder.connector.configuration.ConfigurationPathBuilder</basePathBuilderImpl> </config>
這裏最重要的一個參數就是baseURL,我設置的路徑是‘/MyBlog/userfiles/’，這裏需要注意的是必須加上完整項目名，不加項目名則無法預覽，這也是我在這篇博文發表後第二天修改的原因，昨晚發表時沒注意這問題，以爲能上傳服務器就ok了，當選擇圖片後則回到預覽的畫面，出現紅色的叉號，總之，只要是ckeditor跟ckfinder無法上傳的問題，基本上都是路徑配置問題，好好看看路徑，一般都能解決
另外上那自定義的攔截器，繼承struts2默認的攔截器，這樣就在上面的web.xml中用這攔截器攔截請求，好處就是按照自己的需求攔截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來實現的,它也是通過攔截URL的機制進行工作的,而strutes2的攔截器咱一般配置<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern> struts2會攔截所有以"/"開頭的URL.所以ckeditor的編輯器就被strut2攔截了這也是今天晚上困擾我的問題，一直點瀏覽服務器，雖然出現files，images，falsh這幾個文件夾，但是點上傳後出現紅色的歎號，後來突然醒悟，原來是struts2攔截了！！
所以重寫攔截器的目的也就是不讓struts2攔截ckfinder的servlet，所以要分割url字符串，假如是ckeditor，那麼split（/ckfinder/..）後就能至少分2段，這樣就直接轉發，不攔截。
ckfinder這插件是用來處理ckeditor上傳下載的功能的
圖片暫時上不來 不知道爲什麼一直顯示圖片不正常
