即使play.ap.db.DB可以为同一个驱动程序执行此操作，也无法使用驱动程序连接到Redshift数据库

I am trying to connect to a redshift server and run some sql commands. Here is the code that I have written. Class.forName("org.postgresql.Driver") val url: String = s"jdbc:postgres://${user}:${password}@${host}:${port}/${database}" val connection: Connection = DriverManager.getConnection(url, user, password) val statement = connection.createStatement(ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY) val setSearchPathQuery: String = s"set search_path to '${schema}';" statement.execute(setSearchPathQuery) But I am getting the following error.

我正在尝试连接到redshift服务器并运行一些sql命令。这是我写的代码。 Class.forName（“org.postgresql.Driver”）val url：String = s“jdbc：postgres：// $ {user}：$ {password} @ $ {host}：$ {port} / $ {database}” val连接：Connection = DriverManager.getConnection（url，user，password）val statement = connection.createStatement（ResultSet.TYPE_FORWARD_ONLY，ResultSet.CONCUR_READ_ONLY）val setSearchPathQuery：String = s“set search_path to'$ {schema}';” statement.execute（setSearchPathQuery）但是我收到以下错误。

java.sql.SQLException: No suitable driver found for jdbc:postgres://user:password@host:port/database

java.sql.SQLException：没有为jdbc找到合适的驱动程序：postgres：// user：password @ host：port / database

But when I am using play framework's default database library with the same configuration, then I am able to connect to database successfully. Below is the configuration for the default database.

但是当我使用具有相同配置的play框架的默认数据库库时，我能够成功连接到数据库。以下是默认数据库的配置。

db.default.driver=org.postgresql.Driver db.default.url="postgres://username:password@hostname:port/database" db.default.host="hostname" db.default.port="port" db.default.dbname = "database" db.default.user = "username" db.default.password = "password"

db.default.driver = org.postgresql.Driver db.default.url =“postgres：// username：password @ hostname：port / database”db.default.host =“hostname”db.default.port =“port” db.default.dbname =“database”db.default.user =“username”db.default.password =“password”

The problem was with the url. The correct format for the url is "jdbc:postgresql://hostname:port/database".

问题出在网址上。 url的正确格式是“jdbc：postgresql：// hostname：port / database”。
