使用 Oracle 19C 兼容 ojdbc8.jar 启动时出现警告 tomcat

Question

我们曾经在 tomcat/lib 中有一个与 Oracle 12C 兼容的环境 ojdbc8.jar。哪个工作正常。

我们正在将 Oracle 升级到 19C，因此 JDBC 驱动程序。我们从以下位置下载了新的驱动程序：https://www.oracle.com/database/technologies/appdev/jdbc-ucp-19c-downloads.html

在 tomcat/lib 中只有 ojdbc8.jar，tomcat 记录警告。

知道没有使用 Oracle 钱包，忽略此警告有多重要？

有没有办法避免在服务器启动时出现这样的警告？要么添加 oraclepki.jar（以及随后的其他几个）是唯一的选择吗？

Answer 1

刚刚意识到这是由 tomcat 9.0.11 中的 apache 处理的。他们在跳过列表中添加了 oraclepki.jar。我已经验证了这个版本，没有更多的警告被记录。
