spring-boot集成ckfinder遇到的問題

項目重構，採用springboot 在集成ckfinder中出現WEB-INF/ckfinder.xml 文件找不到，初始化失敗 在開發工具裏面能夠，打包之後有問題。主要是Configuration類中的 init 調用 getFullConfigPath方法致使的 springboot對 相對目錄API不能使用，servletContext.getRealPath(「/」) 返回的NULL

(1) 不能把ckfinder.xml 放在WEB-INF 目錄下面，放在classpath下面

(2) 自定義Configuration，重寫了init方法，主要是修改獲取xml的方法，超類中用的是

File file = new File(ServletContextFactory.getServletContext().getRealPath(this.xmlFilePath)); 將獲取xml配置的方法改成 用ResourceLoader 從classpath 抓取

@override
public void init() throws Exception {
