6

与此问题类似的问题，但没有帮助。

目前，我已将 h2 部署在亚马逊主机上的 Jboss 6 服务器上。我正在使用以下详细信息尝试连接

            Connection conn = DriverManager.getConnection(
            "jdbc:h2:~/test", "-user",
            "");

我尝试了许多其他组合，包括上面链接的组合，并使用了教程中提供的详细信息，但似乎没有任何效果。以下是堆栈跟踪。

我曾经遇到过完全相同的问题：我无法访问基于 H2 文件的数据库。我从不为 H2 数据库指定任何密码用户。当我遇到连接问题“错误的用户名或密码”时，之前运行的应用程序已经存在一个文件。删除现有的 *.db 文件解决了这个问题（我猜它是使用生成的用户/密码对创建的，此后发生了变化）。

你的用户名真的是“-user”吗，密码是空字符串吗？您正在DriverManager.getConnection(String url, String user, String password)使用参数调用该方法

  • url = "jdbc:h2:~/test"
  • user = "-user"
  • password = ""（空字符串）

如果您希望用户名和密码都是空字符串，您有两种选择：

DriverManager.getConnection("jdbc:h2:~/test", "", "");
DriverManager.getConnection("jdbc:h2:~/test");
