我正在开发我的第一个 micronaut 应用程序，但在使用 ucp 配置 oracle 多个数据源时遇到问题。
当我尝试执行选择时，我正在关注官方教程（https://micronaut-projects.github.io/micronaut-sql/latest/guide/ ），出现错误：
io.micronaut.transaction.jdbc.exceptions.CannotGetJdbcConnectionException: No current JDBC Connection found. Consider wrapping this call in transactional boundaries.
我检查了 DataSourceFactory 并且 PoolDataSource 设置正确
我错过了什么？
谢谢！
