配置文件：
CKEDITOR.editorConfig = function( config ) { // 配置ckeditor的默認語言 config.language = 'zh-cn'; // 編輯器樣式 config.skin = 'v2'; // 設置工具欄 config.toolbar_Full = [ [ 'Source', '-', 'Save', 'Preview', ], [ 'Cut', 'Copy', 'Paste', 'PasteText', 'PasteFromWord', '-','Print', 'SpellChecker', 'Scayt' ], [ 'Undo', 'Redo', '-', 'Find', 'Replace', '-', 'SelectAll','RemoveFormat' ], '/', [ 'Bold', 'Italic', 'Underline', 'Strike', '-', 'Subscript','Superscript' ], [ 'NumberedList', 'BulletedList', '-', 'Outdent', 'Indent' ], [ 'JustifyLeft', 'JustifyCenter', 'JustifyRight', 'JustifyBlock' ], [ 'Link', 'Unlink', 'Anchor' ], [ 'Image', 'Flash', 'Table', 'HorizontalRule', 'Smiley', 'SpecialChar', 'PageBreak' ], '/', [ 'Styles', 'Format', 'Font', 'FontSize' ], [ 'TextColor', 'BGColor' ] ]; // 設置快捷鍵 config.keystrokes = [ [ CKEDITOR.ALT + 121, 'toolbarFocus' ], // 獲取焦點 [ CKEDITOR.ALT + 122, 'elementsPathFocus' ], // 元素焦點 [ CKEDITOR.SHIFT + 121, 'contextMenu' ], // 文本菜單 [ CKEDITOR.CTRL + 90, 'undo' ],// 撤銷 [ CKEDITOR.CTRL + 89, 'redo' ], // 重做 [ CKEDITOR.CTRL + CKEDITOR.SHIFT + 90, 'redo' ], [ CKEDITOR.CTRL + 76, 'link' ],// 鏈接 [ CKEDITOR.CTRL + 66, 'bold' ],// 粗體 [ CKEDITOR.CTRL + 73, 'italic' ], // 斜體 [ CKEDITOR.CTRL + 85, 'underline' ], // 下划線 [ CKEDITOR.ALT + 109, 'toolbarCollapse' ] ] // 設置默認字體 config.font_defaultLabel = 'Arial'; // 設置字體種類 config.font_names = 'Arial;黑體;宋體;仿宋;GB_2312'; // 換行方式 config.enterMode = CKEDITOR.ENTER_BR; // 當輸入：shift+Enter是插入的標簽 config.shiftEnterMode = CKEDITOR.ENTER_BR; //請求路徑： //config.baseHref = 'http://localhost:8080/ckps/'; // 配置文件上傳和顯示路徑 config.filebrowserBrowseUrl = 'servlet/BrowerUpload'; config.filebrowserUploadUrl = 'servlet/CKEditorUpload'; config.filebrowserImageUploadUrl = 'servlet/CKEditorUpload?type=Images'; config.filebrowserFlashUploadUrl = 'servlet/CKEditorUpload?type=Flashs'; config.filebrowserImageBrowseUrl = 'servlet/BrowerUpload?type=Images'; config.filebrowserFlashBrowseUrl = 'servlet/BrowerUpload?type=Flashs'; };
java的我們用servlet來進行文件上傳的實現，其實網上已經有普通用的版本了，但是，總是多少有路徑的限制問題，我自己研究了一早上，終於攻克了這個讓人惡心的問題。我的博客里有3篇CKEditor的配置和應用的文章，那個是從別人的博文里拷貝的。起初寫了個小demo，測試了下，可以用。上傳功能用的是的jsp實現。我一般這些東西都會換着路徑來測試可否正常使用的。果然，我新建了文件夾，放到非根目錄，就有了路徑問題了，無法實現任意路徑的正常上傳了。然后我繼續網上查資料，發現有用servlet實現的。就參考了下，果然。還是根目錄可以，非根目錄還是不行。細節就不多說了。我的解決方法是用的servlet，因為servlet的路徑可以配置成擴展模式，可以方便非根路徑的映射。下面就是代碼展示了：
前端：
<body> <div style="width:671px;"> <form action="<%=path %>/UploadA" method="post"> <textarea cols="80" id="content" name="content"></textarea> <script type="text/javascript"> CKEDITOR.replace('content',{ filebrowserImageBrowseUrl : 'servlet/BrowerUpload.brower', filebrowserImageUploadUrl:'servlet/CKEditorUpload.upload'}); </script> <input type="submit" value="提交"/> </form> </div> </body>
web.xml
<servlet> <servlet-name>CKEditorUpload</servlet-name> <servlet-class>com.xxx.util.CKEditorUpload</servlet-class> </servlet> <servlet> <servlet-name>BrowerUpload</servlet-name> <servlet-class>com.xxx.util.BrowerUpload</servlet-class> </servlet> <servlet-mapping> <servlet-name>CKEditorUpload</servlet-name> <url-pattern>*.upload</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>BrowerUpload</servlet-name> <url-pattern>*.brower</url-pattern> </servlet-mapping>

后台：瀏覽的servlet:com.xxx.util.BrowerUpload

這樣就可以了。前端代碼可以寫在任何路徑下。只要servlet的匹配模式寫正確就沒有問題了。
