Dockerized Spring 啟動應用程序連接到 mongoDB docker 圖像不工作

Question

我試圖弄清楚為什么 dockerized Spring 啟動應用程序和 mongoDB 之間的通信不起作用。 第一件事：整個微服務在本地完美運行。 我創建了一個配置文件名稱為 docker 的 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

然后是 docker-compose.yml

啟動 docker 后...

mvn clean package -P "build-docker-image"
docker compose up -d

我在某個地方犯了一個錯誤。 如果有提示，我將不勝感激。

Answer 1

您在配置文件的spring.data.mongodb.uri中缺少一個“s”。
