import java.sql.*; 


public class ConnectionManager { 

    static Connection conn; 
    static String url; 


    public static Connection getConnection() 
    { 
    try 
    {   

     Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");

嗯，「usersetup.db」不會碰巧是SQLite數據庫嗎？如果是這樣，那麼UCanAccess無法打開它。 UCanAccess只能打開Access數據庫（.accdb，.mdb或相關）。 –

如何打開sqlite數據庫？ –

nvm在https://www.tutorialspoint.com/sqlite/sqlite_java.htm找到，不知道不同的數據庫有不同的連接方法 –

你是試圖用UCanAccess打開一個SQLite數據庫，這是行不通的。 UCanAccess只能打開Access數據庫（.accdb，.mdb或相關）。要使用SQLite數據庫，您需要使用像Xerial的SQLite JDBC Driver。
