路径参数：路径无效Scala播放配置文件

我收到了我的application.conf文件内部的解析异常。路径参数：路径无效Scala播放配置文件

这里是我的application.conf

db.test.driver = org.postgresql.Driver 
db.test.user = "postgres" 
db.test.password = "postgres" 
db.test.url = "jdbc:postgresql://localhost:5432/gasguru"

这里是我试图使用从我application.conf

trait DbConfigWeb extends DbConfig { qualifier: DbQualifier => 

    def url: String = current.configuration.getString(qualifier + ".url").get 
    println(url) 
    def username: String = current.configuration.getString(qualifier + ".user").get 
    def password: String = current.configuration.getString(qualifier + ".password").get 
    def driver: String = current.configuration.getString(qualifier + ".driver").get 
    override def database: DatabaseDef = JdbcBackend.Database.forURL(url, username, password, null, driver) 

    override implicit val session = database createSession 
} 

trait DbQualifier { 
    val qualifier: String 
} 

trait DbProductionQualifier extends DbQualifier { 
    override val qualifier = "db.production" 
} 

trait DbTestQualifier extends DbQualifier { 
    override val qualifier = "db.test" 
}

这里阅读代码我试图运行测试用例：

class DbConfigWebUnitTest extends PlaySpec with OneAppPerSuite with BeforeAndAfterAll { 


     "DbConfigWebTest" must { 
     "have the same username as what is defined in application.conf" in { 
      val dbManagementWeb = new DbConfigWeb with DbTestQualifier 
      dbManagementWeb.username must be("postgres") 
     } 

     "have the same password as what is defined in application.conf" in { 
      val dbManagementWeb = new DbConfigWeb with DbTestQualifier 
      dbManagementWeb.username must be("postgres") 
     } 


     "have the qualifier db.test" in { 
      val dbManagementWeb = new DbConfigWeb with DbTestQualifier 
      dbManagementWeb.qualifier must be ("db.test") 
     } 
     } 


    }

最后错误信息：

您将一个对象与一个字符串连接起来，该字符串将调用产生[email protected]的默认toString方法。您需要从特征中调用方法：

current.configuration.getString(qualifier.qualifier + ".url").get

并且在其他调用上也执行相同的操作。

或者你可以重写toString方法返回预选赛值，并使用它，你正在使用它现在

trait DbQualifier { 
    val qualifier: String 
    override def toString = qualifier 
}

以同样的方式
