播放2框架中的几个数据源与光滑

Question

如何在Play 2.5.x Framework和Slick中配置和使用多个数据源？ 例如，一个数据源应该是MySQL，另一个数据源应该是PostgreSQL。

slick.dbs.default.driver = "utils.db.TetraoPostgresProfile$" 
    slick.dbs.default.db.driver = "org.postgresql.Driver" 
    slick.dbs.default.db.url = "jdbc:postgresql://localhost:5432/templatesite_db" 
    slick.dbs.default.db.user = "user" 
    slick.dbs.default.db.password = "pass" 

    slick.dbs.secondary.driver = "slick.jdbc.MySQLProfile$" 
    slick.dbs.secondary.db.driver = "com.mysql.jdbc.Driver" 
    slick.dbs.secondary.db.url = "jdbc:mysql://localhost:3306/dbName" 
    slick.dbs.secondary.db.user = "root" 
    slick.dbs.secondary.db.password = "pass" 

Answer 1

这在ScalaDatabase docummentation页面直接寻址：

// inject "orders" database instead of "default" 
class ScalaInjectNamed @Inject()(
    @NamedDatabase("orders") db: Database) extends Controller { 
    // do whatever you need with the db 
}
