Question

我有一个需要数据库连接的应用程序。我正在尝试运行它，但无法正常运行。仅创建具有db的容器。在我看来，它可以正常工作，因为如果我在Eclips中运行应用程序，它将连接到数据库容器。

应用程序属性

server.port=9200
spring.datasource.url=jdbc:mysql://localhost:3306/currency-converter1?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=CONVERT_TO_NULL&serverTimezone=GMT
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.testWhileIdle=true
spring.datasource.validationQuery=SELECT 1
spring.jpa.properties.hibernate.id.new_generator_mappings=false
spring.jpa.hibernate.ddl-auto=create
spring.jpa.show-sql=true
spring.jpa.hibernate.naming-strategy=org.hibernate.cfg.ImprovedNamingStrategy
spring.messages.encoding=UTF-8

Dockerfile

EXPOSE 9200
