我正在尝试在docker容器中运行一个spring boot应用程序，链接到docker mysql容器。当我尝试使用弹簧启动应用程序运行docker容器时，我收到以下错误：

当我尝试运行spring boot应用程序而不将它放在docker容器中时，与mysql容器的连接可以正常工作。

这是我用于spring boot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用于在docker网络中运行两个容器：

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吗？

谢谢！

您已经链接了mysql容器，请尝试。

spring:
    datasource:
        jdbcUrl: jdbc:mysql://mysql:3306/data

flyway:
    datasource:
        jdbcUrl: jdbc:mysql://mysql:3306/data
