spring-boot集成ckfinder遇到的问题

项目重构，采用springboot 在集成ckfinder中出现WEB-INF/ckfinder.xml 文件找不到，初始化失败 在开发工具里面可以，打包以后有问题。主要是Configuration类中的 init 调用 getFullConfigPath方法导致的 springboot对 相对目录API不能使用，servletContext.getRealPath(“/”) 返回的NULL

(1) 不能把ckfinder.xml 放在WEB-INF 目录下面，放在classpath下面

(2) 自定义Configuration，重写了init方法，主要是修改获取xml的方法，超类中用的是

File file = new File(ServletContextFactory.getServletContext().getRealPath(this.xmlFilePath)); 将获取xml配置的方法改为 用ResourceLoader 从classpath 抓取

@override
public void init() throws Exception {
    DefaultResourceLoader loader = new DefaultResourceLoader();
    Resource resource = loader.getResource(this.xmlFilePath);
