从注入的数据源获取连接在 Micronaut 数据 JDBC 中抛出多个数据源的异常

Question

无法像 spring 那样从注入的数据源获取连接，如文档中所写（配置多个数据源）https://micronaut-projects.github.io/micronaut-sql/latest/guide/#:~:text=Configuring%20Multiple%20Data%20Sources throws

Answer 1

我通过展开注入的 DataSource (more) 解决了我的问题:

DataSource db1Ds = ((DelegatingDataSource) db1DataSource).getTargetDataSource();
Connection db1Conn = db1Ds.getConnection();
/* or
Connection db1Conn = ((DelegatingDataSource) db1DataSource).getConnection();
*/

不知道有没有捷径
