Dockerized Spring boot应用程序连接到mongoDB docker镜像不起作用

Question

我试图找出为什么 dockerized Spring boot 应用程序和 mongoDB 之间的通信不起作用。首先要做的事情是： 整个微服务在本地完美运行。 我使用配置文件名称 docker 创建一个 application.properties： application-docker.properties

server.port=8091
spring.application.name=customer
# ============================================================================================================
# EUREKA
# It's not possible to use localhost in the docker container. Instate use the container name.
# In this case "eureka-server". See the file docker-compose.yml to check the container name.
eureka.client.service-url.defaultZone=http://eureka-server:8761/eureka
eureka.client.fetch-registry=true
eureka.client.register-with-eureka=true
# ============================================================================================================
# ZIPKIN
# It's not possible to use localhost in the docker container. Instate use the container name.
# In this case "zipkin". See the file docker-compose.yml to check the container name.
spring.zipkin.base-url=http://zipkin:9411
# ============================================================================================================
# RABBIT_MQ
# It's not possible to use localhost in the docker container. Instate use the container name.
# In this case "rabbitmq". See the file docker-compose.yml to check the container name.
spring.rabbitmq.addresses=rabbitmq:5672
rabbitmq.exchanges.internal=internal.exchange
rabbitmq.queue.notification=notification.queue
rabbitmq.routing-keys.internal-notification=internal.notification.routing-key
# ============================================================================================================
# MONGO-DB
spring.data.mongodb.authentication-database=admin
spring.data.mongodb.username=rootuser
spring.data.mongodb.password=rootpass
#spring.data.mongodb.database=data
#spring.data.mongodb.host=spring
#spring.data.mongodb.port=27017
spring.data.mongodb.uri=mongodb://mongodb:27017/data

，然后启动 docker 后的 docker-compose.yml

您的配置文件中的 spring.data.mongodb.uri 中缺少“s”。
