无法在 play 2.4 中连接到 Oracle 数据库

Question

很多天以来，我一直在尝试使用 Play 2.4 框架连接到 Oracle 数据库，但我所有的尝试都是徒劳的。因此，为此寻求一些解决方案。我在 application.conf 中尝试了以下配置，但 none 有效：

db.default.driver=oracle.jdbc.driver.OracleDriver
db.default.username=user_name
db.default.password=password

1) db.default.url="jdbc:oracle:thin:@host_name:host_port:sid"
2) db.default.url="jdbc:oracle:thin://@host_name:host_port/sid"
3) db.default.url="jdbc:oracle:thin://host_name:host_port/sid"
4) db.default.url="jdbc:oracle:thin:@host_name:host_port:sid"
   db.default.host=host_name
5) db.default.url="jdbc:oracle:thin://@host_name:host_port/sid"
   db.default.host=host_name
6) db.default.url="jdbc:oracle:thin://host_name:host_port/sid"
   db.default.host=host_name

以下是我在每种情况下遇到的异常：

CreationException: Unable to create injector, see the following errors:

感谢大家看我的问题，最后参考网上的帖子和play 2.4的文档，下面是对这个问题的回答：

  a) Url format for oracle will be as below:
     db.default.url="jdbc:oracle:thin:@host_name:host_port:sid"
  b) Add property as:
     db.default.hikaricp.connectionTestQuery="SELECT 1 FROM DUAL"
     # above query will be used to check connection, this is required.

谢谢，普拉迪普夏尔马
