应用程序在版本 2.2.6 下正常工作，但随着应用程序升级到最新版本的 spring boot 2.3.0，它停止工作并在启动过程中失败。

读取类路径资源，

    try {
        final ClassPathResource classPathResource = new ClassPathResource(format("location%sGeoLite2-City.mmdb", File.separator));
        final File database = classPathResource.getFile();
        dbReader = new DatabaseReader.Builder(database).build();
    } catch (Exception e) {
        System.out.println("Exception: " + e);
    }

我已经使用以下 Dockerfile 将它与 docker 打包在一起，

FROM java:8
ADD build/libs/*.jar App.jar
CMD java -jar App.jar

但是在以docker run -p 8080:8080 app-image运行此应用程序时，我可以访问应用程序端点，并且从应用程序日志中我可以看到它无法读取此文件（以下来自日志），

Exception: java.io.FileNotFoundException: class path resource [location/GeoLite2-City.mmdb] cannot be resolved to absolute file path because it does not reside in the file system: jar:file:/App.jar!/BOOT-INF/classes!/location/GeoLite2-City.mmdb
