问题描述
我正在尝试将项目从Java 8迁移到使用ojdbc的Java 11.我正在使用一个扩展PoolDataSourceImpl的类，该类实现了PooLDataSource，它扩展了javax.sql.DataSource，并且在尝试使用maven构建它时会出现以下错误:
I am trying to migrate a project from Java 8 to Java 11, which uses ojdbc. I am using a class which extends PoolDataSourceImpl, which implements PooLDataSource, which extends javax.sql.DataSource and while trying to built it with maven it gives this error:
有人有什么建议吗?
推荐答案
问题是您尝试将PoolDataSourceImpl子类化，这是使用JDK8编译的特定于供应商的类，除非明确建议这样做，否则我们不支持扩展我们的类.因此，例如此博客；所有软件供应商都是如此.作为此限制的一部分，我们的驱动程序(ojdbc8.jar，ucp.jar)与较新的JDK版本(即，可与JDK11一起使用)和数据库版本向前兼容.
The problem is that you try to subclass PoolDataSourceImpl which is a vendor-specific class compiled with JDK8 and we do not support extending our classes unless we explicitly suggest to do so, as in this blog; and this is true for all software vendors.A part from this restriction, our drivers (ojdbc8.jar, ucp.jar) are forward compatible with newer JDK releases (i.e., work with JDK11) and database releases.
这篇关于Java 11迁移-PoolDataSourceImpl中的createConnectionBuilder()与javax.sql.DataSource中的createConnectionBuilder()发生冲突的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
