使用mongodb和Java 11在Docker中运行的spring boot应用程序

Question

我正在docker容器中运行一个简单的spring引导应用程序。以下是我的规范：-spring boot 2.1.3.发行版-Java 11 with Windows 10-Docker use：FROM debian：strett-slim as packager-ENV jdk_version=“11.0.1”

spring boot simple applications可以很好地使用上述配置

当我添加Mongodb（spring数据mongo）并启动spring boor应用程序时，它在我的windows机器中运行良好，但当我在docker容器中运行时，它会抛出如下错误：

我怀疑，spring boot是否完全支持npt Java 11，或者我缺少一些Java模块，我需要添加到我的DockerFile。

到目前为止，我已经将以下Java模块添加到我的DockerFile中：

--add-module\java.base,java.sql,java.naming,java.desktop,java.management,java.security.jgss,java.instrument

任何建议都会有帮助。

我改变了Docker的图像，现在它工作得很好：

这里是Dockerfile，如果您想用Maven为Java 11设置Docker，它很有用。
