我的docker文件如下所示：

FROM openjdk:15

EXPOSE 8080

ADD ./target/app.jar app.jar

ENTRYPOINT ["java", "-jar", "app.jar"]

docker-compose.yml看起来像这样：

version: '3.7'
services:

  api-gateway:
    image: 'api-gateway:1.0'
    build:
      context: ./api-gateway
      dockerfile: Dockerfile
    restart: always
    ports:
      - '8080:8080'
    networks:

networks:
  app-network: null
volumes:

在我看来，docker镜像似乎不包含资源文件夹中的强制属性文件。此外，本地应用程序可以轻松启动。在对接Spring Boot应用程序时，如果我做错了什么，或者如何将整个资源文件添加到容器中，我将不胜感激。

编辑：

ConfigurationReader类：

@Slf4j
public class ConfigurationReader {

  private ConfigurationReader() {}

  private static final String DEFAULT_PROPERTY_VALUE = "";

  @SneakyThrows
  public static Properties readConfigurationFile(String... relativeConfigurationFile) {
    String path = resolveToAbsolutePath(relativeConfigurationFile);
    Path resources = Paths.get(".", "src", "main", "resources", path).normalize().toAbsolutePath();
    try (InputStream fileAsStream = getConfigurationFileAsStream(resources.toString())) {
      Properties properties = new Properties();
      properties.load(fileAsStream);
      return properties;
    } catch (Exception e) {
      log.error("[configurationReader] Cannot read configuration file {}", path);
      throw new FileNotFoundException();
    }
  }

  public static String getProperty(Properties propertyFile, String propertyName) {
    return propertyFile.getProperty(propertyName, DEFAULT_PROPERTY_VALUE);
  }

  private static InputStream getConfigurationFileAsStream(String path) throws IOException {
    Path configurationFilePath = FileSystems.getDefault().getPath(path);
    return Files.newInputStream(configurationFilePath, StandardOpenOption.READ);
  }

  private static String resolveToAbsolutePath(String... relativeConfigurationPath) {
    return String.join(FileSystems.getDefault().getSeparator(), relativeConfigurationPath);

您正在尝试加载文件src/main/resources/redis.properties。只有当您的应用程序的源代码可用，并且工作目录是源代码树的根目录时，此文件才会存在。如果在没有可用的源代码的情况下运行jar文件，您将在Docker外部看到相同的故障。

您应该从类路径加载文件，而不是从文件系统加载文件。src/main/resources中的任何文件都可以从类路径的根目录中使用。您可以使用从ConfigurationReader.class.getClassLoader().getResourceAsStream("redis.properties")返回的InputStream加载redis.properties。或者，当您使用Spring Boot时，您可能希望使用Spring Framework的ClasspathResource。
