Java Spring Boot WebApp:无法加载类：com.ibm.as400.access.AS400JDBCDriver

我目前正在使用STS中的Spring Boot制作一个小型Web应用程序。当我试图接近数据库时遇到了一个问题，即使用JDBC的iSeries as/400

由于我在任何地方（在堆栈或网络的其他部分）都找不到问题或答案，我决定问这个问题，我将提供帮助我的答案。

帮助我的是添加了一个依赖项，这是我偶然发现的：

<dependency>
        <groupId>net.sf.jt400</groupId>
        <artifactId>jt400</artifactId>
        <version>9.1</version>
        <scope>provided</scope>
    </dependency>

此外，我建议使用最新版本，即9.1，如果您没有使用Springboot（例如，使用独立的Tomcat，您可以下载jar并将其放入Tomcat/lib文件夹）。此外，我建议使用最新版本，即9.1，如果您没有使用Springboot，（例如，使用独立的Tomcat，您可以下载jar并将其放入Tomcat/lib文件夹）
