版本 ckfinder 2.x

一、概念

參考官網解釋(如果訪問不了,可以點擊最新的官方地址)

Both baseDir and baseURL should point to the same location on the
server — the userfiles directory that contains all user files uploaded
with CKFinder. The difference between them is as follows:

• baseURL gives a full URL to the userfiles directory or a path that is relative to the domain. For example: <baseURL>http://example.com/CKFinderJava/userfiles/</baseURL><baseURL>/CKFinderJava/userfiles/</baseURL>
• baseDir gives an absolute path to the directory on the server (a physical machine). For example: <baseDir>/usr/tomcat/webapps/CKFinderJava/userfiles/</baseDir><baseDir>C:\tomcat\webapps\CKFinderJava\userfiles\</baseDir>

也就是說,baseDir是上傳文件目錄在服務器中的絕對路徑,baseURL是一個瀏覽器的訪問路徑(可以使用相對路徑).

二、配置

baseDir跟baseURL其實都是指向同一個文件目錄,但為什么配置了baseURL之后一般情況下也需要配置baseDir參數？這是因為服務器配置原因導致有可能根據baseURL找不到路徑而出現故障,這個時候baseDir就能派上用場了，因為它是一個絕對路徑，所以不受服務器配置的影響.

三、最佳實踐

1.it is always recommended to set both baseUrl and baseDir so that they point to same location which is outside of an application
directory.
2.First of all you should set both properties so that they point to same location which is accessible through HTTP and from the file
system. Second, you should set these properties to point to location
outside of CKFinder application folder.

baseUrl 、baseDir 指向相同的地方，并且最好把文件上傳的目錄指向應用程序目錄的外面.為什么呢？如果不這樣做的話,每次升級系統重新發布war包都會覆蓋原來的文件上傳目錄.有什么解決方法呢?可以設置虛擬目錄或者符號連接(不推薦，每次發布都要新建符號連接)。如下配置

tomcat 6
在 server.xml文件中增加一個context .

tomcat 7-8
CKFinder config.xml settings:

<baseDir>C:/myimages</baseDir>

<Context antiJARLocking="true" path="/CKFinderJava" reloadable="true" ><Resources><PreResources base="C://myimages" className="org.apache.catalina.webresources.DirResourceSet" webAppMount="/userfiles" /></Resources><Valve className="org.apache.catalina.valves.RemoteAddrValve" allow=".*" /> </Context>
