java - 无法从 Netbeans 12 JavaFX maven 项目加载 jdbc 驱动程序

问题描述

您好，我尝试在使用 Netbeans 12 创建的新 javaFX maven 项目中使用 JDBC 驱动程序，但每次尝试使用 jdbc 驱动程序时，我都会遇到 java.lang.ClassNotFoundException: com.ibm.as400.access.AS400JDBCDriver

我尝试添加其他 jar 依赖项并且它有效。只有 jdbc 驱动程序不起作用。（用 microsoft sql server 也试过同样的问题）

我在 Maven 中添加了依赖项。当我创建一个普通的java maven项目时它可以工作..谢谢
