获取 R2dbcNonTransientResourceException：不支持的 Oracle JDBC 驱动程序版本：19

Question

我正在尝试为我的 Spring 引导应用程序设置 R2DBC，该应用程序以 Oracle 19c 作为数据库并配置了 OJDBC8 和 Java 11。R2DBC 版本为 0.1.0。由于应用程序无法启动，我收到以下错误。 rRDBC 是否适用于 Oracle 19c 还是必须是 Oracle 21x？

Answer 1

错误与 Oracle JDBC 驱动程序版本有关，与您的 Oracle 版本无关。 Oracle R2DBC 驱动程序依赖于 Oracle JDBC 驱动程序中的特定功能，这些功能仅在较新的驱动程序版本中可用，然后仅在 Java 11（或更高）版本的驱动程序（即ojdbc11，不是 ojdbc8)。

根据 https://github.com/oracle/oracle-r2dbc，最新的 Oracle R2DBC 驱动程序需要 Oracle JDBC 21.3 驱动程序。

它还说：

The Oracle R2DBC Driver has been verified with Oracle Database versions 18, 19, and 21.

需要说明的是，Oracle JDBC 21.3 驱动程序可以很好地与 Oracle 19c 配合使用，R2DBC 也是如此。

简而言之，您需要将 Oracle JDBC 驱动程序更新为：

<dependency>
  <groupId>com.oracle.database.jdbc</groupId>
  <artifactId>ojdbc11</artifactId>
  <version>21.3.0.0</version>
</dependency>
