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

【中文标题】使用兼容 Oracle 19C 的 ojdbc8.jar 启动 tomcat 时出现警告

【英文标题】：Warning while starting up tomcat with Oracle 19C compatible ojdbc8.jar

【发布时间】：2020-05-19 04:19:21

【问题描述】：

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

我们正在将 Oracle 升级到 19C 等 JDBC 驱动程序。 我们从：https://www.oracle.com/database/technologies/appdev/jdbc-ucp-19c-downloads.html

下载了新的驱动程序

在 tomcat/lib 中只有 ojdbc8.jar，tomcat 会在警告后记录。

知道没有使用 Oracle 钱包，忽略此警告有多重要？

有没有办法在服务器启动时避免此类警告？ 要么 添加 oraclepki.jar（以及随后的其他几个）是唯一的选择吗？

【参考方案1】：

刚刚意识到这是由 apache 在 tomcat 9.0.11 中处理的。 他们在跳过列表中添加了 oraclepki.jar。我已使用此版本进行了验证，并且不再记录任何警告。
