Java SQL异常数据库已锁定
谁能帮我修复javaJava SQL异常数据库已锁定,java,sql,swing,jtable,Java,Sql,Swing,Jtable,谁能帮我修复javasql异常数据库被锁定。当我单击jtable（accounts\u table）并且该表中的数据进入另一个jtable（accounts\u all）时，以及当我试图通过单击jbutton（acct\u create）创建新帐户时数据库将成功打开，但之后将显示JOptionPane，其中的消息是java sql异常数据库已锁定 private void acct_createActionPerformed(java.awt.event.ActionEvent evt) {

您的帐户、用户名和密码有问题。 如果您超过了重新尝试登录DB的最大次数，则帐户将被锁定 因此，请检查您的帐户密码 当我试图通过单击jb按钮创建新帐户时（acct_create） 数据库将成功打开，但在此之后JOptionPane将 显示，其中的消息为java sql异常数据库已锁定 在任何情况下，您都需要先关闭连接，然后才能打开新的。在这种情况下，请开始调试代码，并将调试点添加到finaly block和to

您能试试吗？帐户密码有最大限制吗？您能告诉我如何解决这个问题吗？您应该检查您的密码并更正它。如果您能够从SQL客户端连接到DB，请使用密码进行检查。我使用的是sqlite，但我没有在DB上连接的密码。似乎我可以在DB上正确连接。您能告诉我正确的调试方法吗？我确实在netbeans中调试了我的代码，但问题仍然存在。我还在我的every try catch块上编写了此代码以关闭连接：}catch（异常e）{JOptionPane.showMessageDialog（null，e）；}最后{try{rs.close（）；pst.close（）；}catch（异常e）{ } }不。我的意思是添加一个调试点来启动
