使用 XPages 休息服务连接到 mysql 时出错

Question

尝试通过 xpages rest 服务连接到 mysql 数据库时出现错误 500 "internal Error"。 Mysql 版本 8，Domino 服务器 9.0.1 FP8。使用 mysql 中的 JDBC jar 文件。谁能帮我解决错误。

错误：

message "Error while reading the relational data"
type    "text"

这是 jdbc 配置文件和驱动程序位置的组合。对于 mysql，配置需要像下面的示例一样配置。感谢 Henrik 加入写作轨道。

<jdbc type="simple">
    <driver>com.mysql.jdbc.Driver</driver>
    <url>jdbc:mysql://9900w7.int.natc-ht.com</url>
    <port>3306</port>
    <databaseName>weather</databaseName>
    <user>root</user>
    <password>password</password>
    <simple>
        <minPoolSize>10</minPoolSize>
        <maxPoolSize>20</maxPoolSize>
    </simple>
