java - 无法使用文件选择器访问 sqlite.db 文件（Java Swing 项目）

问题描述

我无法从远程路径访问 .db 文件，例如

jdbc:sqlite:D:\test\fnovel.db
jdbc:sqlite:C:\Users\2401k\Nox_share\Download\fnovel.db

项目代码（不太复杂的简单连接）

connection = DriverManager.getConnection("jdbc:sqlite:"+path);

当我尝试运行可执行 jar 时，它工作正常，当我尝试从 intellj 项目中使用时，这是我尝试运行可执行 jar 时遇到的错误

java.sql.SQLException: No suitable driver found for jdbc:sqlite:D:\test\fnovel.db

fnovel.db 文件是使用文件选择器选择的，我从中使用绝对路径。我不能包含 .db 文件，因为它的数据是从 Nox 模拟器中提取的。让我知道是否可以使用 PHP 完成相同的项目而没有任何错误我尝试使用 java 因为我无法在我想使用该程序时手动启动/停止 xampp

当我Class.forName("org.sqlite.JDBC");在连接之前添加时java.lang.ClassNotFoundException: org.sqlite.JDBC出现错误
