Oracle11g Play Framework 2.5中的Oracle DB连接器

我有一个简单的Java游戏！框架2.5项目。我想将其连接到AWS RDS中的Oracle DB 11g。我已经将OracleDB连接器放在

/lib

目录中（找到了“ojdbc6.jar”）。我还配置了Ebean和Evolutions插件

当我运行激活器并在浏览器上加载“localhost:9000”时，控制台会显示以下消息：

[info] application - Creating Pool for datasource 'default'
[warn] c.z.h.u.DriverDataSource - Registered driver with driverClassName=oracle.jdbc.driver.OracleDriver was not found, trying direct instantiation.
[info] application - Creating Pool for datasource 'default'
[warn] c.z.h.u.DriverDataSource - Registered driver with driverClassName=oracle.jdbc.driver.OracleDriver was not found, trying direct instantiation.

这之后是evolutions页面，在接受evolutions之后出现错误。这是堆栈跟踪：

[error] application -

我不知道发生了什么事。好像是那出戏！无法识别给定的连接器，但我只是关注wiki。

我遇到了相同的问题，使用ojdbc6.jar和Oracle Db 11g，但在Play 2.7.x中，在“[warn]c.z.h.u.DriverDataSource-driverClassName=Oracle.jdbc.driver.OracleDriver的注册驱动程序未找到，尝试直接实例化”应用程序仍然能够连接到数据库

无论如何，我通过更改OracleDriver类路径（显然是错误的）消除了该警告：在application.conf中，我将“db.default.driver=oracle.jdbc.OracleDriver”设置为“db.default.driver=oracle.jdbc.driver.OracleDriver”。这应该足以删除警告，但我不确定这是否能解决您特定情况下的后续错误
