我将 JPA(hibernate) 用于 ORM，将 c3po 用于连接池。虽然我能够执行所有 CRUD 操作，但在访问数据时会出现以下错误：

以下是工具：Hibernate 3.2.1、Oracle 10g、ojdbc14、连接池：c3p0-0.9。

和堆栈跟踪：

下载最新的JDBC驱动，我想你至少需要10.2.0.1的驱动和db也需要10.2+

您的数据库可能不支持检索自动生成的密钥：

Oracle 10.1.0 支持：

完全支持 JDBC 3.0，除了：
检索自动生成的键
结果集可保存性
返回多个结果集。

Oracle 10.2.0 支持：

完全支持 JDBC 3.0
请注意，数据库中对以下内容的支持没有真正的变化。所改变的只是以前抛出 SQLException 的一些方法现在做了一些更合理的事情。
结果集可保持性
返回多个结果集。

在这种情况下，尝试设置hibernate.jdbc.use_get_generated_keys为false禁用JDBC3PreparedStatement.getGeneratedKeys()在插入后检索本地生成的密钥。

这是您问题的症结，oracle.jdbc.OracleDatabaseMetaData.supportsGetGeneratedKeys(OracleDatabaseMetaData.java:4180)尝试更改或不使用与获取生成的密钥相关的注释。
