我正在尝试使用spring boot + docker-compose + mysql的示例应用程序。下面是我的docker-compose,yml file

mysql:
  image: mysql:latest
  container_name: mysql-db
  restart: always
  command: --default-authentication-plugin=mysql_native_password
  ports:
    - "33061:3306"
  networks:
    - spring-boot-mysql-net
  environment:
    MYSQL_DATABASE: practice_db
    MYSQL_ROOT_PASSWORD: root
  volumes:
    - ./database_storage:/docker-entrypoint-initdb.d

practice-service:
  container_name: practice-service
  build:
    context: ./
    dockerfile: Dockerfile
  ports:
    - "8080:8080"
  depends_on:
    - mysql
  networks:
    - spring-boot-mysql-net
  restart: on-failure
  command: sh -c './wait-for mysql:3306 -- npm start'

phpMyAdmin:
  image: phpMyAdmin/phpMyAdmin
  container_name: phpMyAdmin
  restart: always
  depends_on:
    - mysql
  environment:
    PMA_HOST: database
    PMA_PORT: 3306
  ports:
    - "9091:80"

networks:
  spring-boot-mysql-net:
    driver: bridge

应用程序。属性

spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://mysql:3306/practice_db
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type.descriptor.sql.BasicBinder=TRACE
spring.jpa.hibernate.naming.physical- 
strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

但我的 Spring Boot 应用程序在连接到MySQLDB时出错

2023-02-11 16:31:10 com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure
2023-02-11 16:31:10 The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
2023-02-11 16:31:10 Caused by: java.net.ConnectException: Connection refused

另外，我试图运行phpMyAdmin，但也没有连接到MySQL。我不确定MySQL容器是否启动，因为我可以看到它的日志-
