我正在尝试从我的 play 2.7 应用程序连接到我的 postgres 数据库。 数据库是一个使用
初始化的 docker 镜像docker run -d --name backend_local - p 127.0.0.1:5432:5432 -e POSTGRES_USER=markos -e POSTGRES-PASSWORD=**** -e POSTGRES_DB=backend_db --restart always registry.gitlab....
我的配置文件如下所示
# Database
db.default.driver=org.postgresql.jdbc.Driver
db.default.url="jdbc:postgresql://localhost:5432/backend_db"
db.default.username="markos"
db.default.password="****"
db.default.logSql=true
看不到连接有问题，但我仍然遇到无法初始化数据库[默认]
我收到的日志

最佳答案
似乎我处理数据库配置的 local_dev.conf 被放错了位置，远离了原来应该位于的conf 文件!
