与MySQL容器春季启动应用程序工作，但与春季启动应用程序容器它不
我试图运行一个docker容器内的一个spring启动应用程序，链接到docker的MySQL容器。 当我尝试运行与弹簧启动应用程序里面的docker容器我收到以下错误：

当我尝试运行没有在docker容器中的弹簧启动应用程序，与MySQL容器的连接工作。
这是我用于spring引导应用程序的application.yml：
server: port: 8081 spring: datasource: username: root password: root testWhileIdle: true validationQuery: SELECT 1 jdbcUrl: jdbc:mysql://127.0.0.1:6603/data type: com.zaxxer.hikari.HikariDataSource jpa: show-sql: true generate-ddl: false hibernate: ddl-auto: none naming-strategy: org.hibernate.cfg.ImprovedNamingStrategy flyway: datasource: username: root password: root jdbcUrl: jdbc:mysql://127.0.0.1:6603/data type: com.zaxxer.hikari.HikariDataSource flyway: locations: classpath:/db/migration logging: file: logs/cookbook-journal.log pattern: console: "%d %-5level [%thread] %logger{0} : %msg%n" file: "%d %-5level [%thread] %logger{0} : %msg%n" level: root: INFO org.springframework.security: DEBUG security: oauth2: resource: userInfoUri: http://localhost:8081/me
和Dockerfile：
FROM java:9 ADD target/ /opt/cookbook-journal/ ENTRYPOINT ["/usr/bin/java", "-jar", "/opt/cookbook-journal/CookbookJournalBackend.jar"]
和docker-compose.yml在Dockernetworking中运行两个容器：
version: '3' services: mysql: image: cookbook-mysql container_name: mysql ports: - "6603:3306" networks: - bridge backend: image: cookbook-backend-img container_name: server ports: - "8081:8081" depends_on: - mysql links: - mysql networks: - bridge networks: bridge: driver: bridge
[编辑]这是用于mysql容器的Dockerfile：
FROM mysql ENV MYSQL_HOST=mysql ENV MYSQL_DATABASE=data ENV MYSQL_ROOT_PASSWORD=root RUN echo [mysqld] > /etc/mysql/my.cnf RUN echo lower_case_table_names=1 >> /etc/mysql/my.cnf
每个人都有这样的问题？
谢谢！
你已经链接了mysql容器，所以试试吧。
spring: datasource: jdbcUrl: jdbc:mysql://mysql:3306/data flyway: datasource: jdbcUrl: jdbc:mysql://mysql:3306/data
