无法使用数据库客户端连接到数据库容器。

Flyway的错误日志中出现以下消息：

我尝试过从Stackoverflow上找到几种解决方案来解决问题。 我已经尝试过更改application.properties文件。 还尝试通过init.sql创建新用户。 使用docker-compose，我尝试设置MySQL-root-password。 docker-compose.yml 
version: '3'

我该如何连接到MySQL容器？ 我的docker-compose文件有什么问题吗？ 还是说我们需要打开3306端口？

原始答案： "Original Answer"

从日志中 spring-boot-jpa-docker-webapp_1 | Message : Access denied for user 'root'@'172.19.0.3' (using password: NO) 可以看出，您的应用程序仍在使用 root 凭据来进行数据库身份验证，请先检查您的应用程序。 - nivhty
你的数据库是否允许访问端口？我会在compose文件的数据库设置中添加PORT <外部端口>： <MySQL标准端口>。也许在你的情况下，使用EXPOSE而不是PORT就足够了。 - user8914226

自从Spring Boot 2.x以来，flyway配置键需要加上前缀spring.: 
spring.flyway.user=thelegend27
spring.flyway.password=1234

没有这个前缀，您的设置将被忽略，并默认为root用户和空密码。

设置空的MYSQL_ROOT_PASSWORD环境变量本来是有效的，除了一个拼写错误：

- MYSQL_ALLOW_EMPTY_PASSWOR=yes
应该是：

应该是：

- MYSQL_ALLOW_EMPTY_PASSWORD=yes
