打开config.xml当中可以看到如下配置

 

<basePathBuilderImpl>com.ckfinder.connector.configuration.ConfigurationPathBuilder</basePathBuilderImpl>

 

打开这个类的源代码

一共俩个方法，一个是获取资源URL的，一个是获取服务器端文件路径的，所以我们复写这俩个方法实现我们自己的逻辑就可以了。

public class MyConfigurationPathBuilder extends ConfigurationPathBuilder {



    private String getCustomPath(HttpServletRequest request) {

        return request.getSession().getAttribute("bathPath").toString();

        //return "EP/";

    }

    

    

    /**

     * Gets configuration value of baseUrl. When config value is not set, then

     * return default value.

     *

     * @param request request

     * @return default baseDir value

     */

    @Override

    public String getBaseUrl(final HttpServletRequest request) {

        return super.getBaseUrl(request)+ getCustomPath(request);

    }



    /**

     * Gets configuration value of baseDir. When config value is not set, then

     * return default value.

     *

     * @param request request

     * @return default baseDir value

     */

    @Override

    public String getBaseDir(final HttpServletRequest request) {

        return super.getBaseDir(request) + getCustomPath(request);

    }

}
