Question

我想在我的Java Servlet Server中使用SQLite。所以我写了一个单例数据库控制器，我在我的servlet中的init函数中初始化。当我到达以下行

Connection connection = DriverManager.getConnection(url);

我得到了这个例外：

java.sql.SQLException: No suitable driver found for jdbc:sqlite:database.db

我测试了在servlet应用程序之外的新项目中获得连接，一切正常。

我正在使用Eclipse Jee Oxygen并使用Add External JARs ..来添加sqlite-jdbc-3.21.0.jar

我该怎么做才能解决这个问题？我已经尝试过.db文件的绝对路径和相对路径。

Answer 1

您需要将sqlite-jdbc-3.21.0.jar添加到您的服务器类路径中，您可以将它放在tomcat服务器的lib文件夹中，或者您可以将此jar放在WEB-INF / lib文件夹中你的项目。

找不到合适的jdbc驱动程序：sqlite：database.db
