【问题描述】：
我在 JMeter 中添加了以下插件：
- mysql-connector-java-5.1.46.jar
- mssql-jdbc-6.4.0.jre9.jar
当我尝试使用 Java 9 通过 JMeter 4.0 执行与 [com.microsoft.sqlserver.jdbc.SQLServerDriver] 的 JDBC 连接时，我在日志中遇到问题：

为什么会这样？我该如何解决这个问题？
【问题讨论】：
-
虽然我写了这个 - 找到了答案 ~[mssql-jdbc-6.2.1.jre8.jar:?] lib 文件夹中有两个插件（这个和最新的）。只需删除“jre8”就可以了！
-
在使用 SQL Server 时，为什么还要使用 MySQL 驱动程序？
