玩！ framework 2.7 - 无法连接到数据库

Question

我正在尝试从我的 play 2.7 应用程序连接到我的 postgres 数据库。数据库是用

初始化的 docker 图像

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....

我的配置文件是这样的

# 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，但我仍然得到 无法初始化数据库[默认]

我得到的日志

Answer 1

看来我处理数据库配置的 local_dev.conf 被放错了原来应该位于的 conf 文件之外！
