You are setting mongodb host in property file as localhost. In a container localhost address itself, but your mongodb is notin that container(car-service) which car-service run in. While you are using docker compose, you can address a container with its name. In your case it is mongodb.
您正在属性文件中将 mongodb 主机设置为localhost。在容器本地主机地址本身中，但您的 mongodb不在运行汽车服务的那个容器（汽车服务）中。当您使用 docker compose 时，您可以使用其名称来寻址容器。在您的情况下，它是mongodb。

to clarify @barbakini's answer, to define it in applications.yaml use:
澄清@barbakini 的答案，在applications.yaml 中定义它使用：
spring.data.mongodb.host: mongodb
