CKFinder 自定义文件路径扩展ConfigurationPathBuilder

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);
    }
}
