我将我的容器应用程序连接到数据库容器时遇到问题。数据库容器正在工作，我可以使用计算机上的应用程序连接到它。我尝试了不同的解决方案，但没有一个提供帮助，因此我决定在此处撰写我的文章。我提前为我的英语道歉。
我正在寻求帮助，因为我想知道我做错了什么。
这是我的代码：
application.properties
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
server.port=9200
spring.datasource.url=jdbc:mysql://localhost:3306/currency-converter?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
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
