Question

与this question类似的问题，但没有帮助。

我现在已经在亚马逊主机上的Jboss 6服务器上部署了h2。我正在使用以下详细信息来尝试连接

            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，似乎没有任何效果。以下是堆栈跟踪。

Answer 1

我曾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＆＃34;错误的用户名或密码＆＃34;时，已经存在上一次运行应用程序的现有文件。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，自那以后已经改变了。）

Answer 2

您的用户名是否真的“ - user”，密码是否为空字符串？您正在使用参数

调用方法DriverManager.getConnection(String url, String user, String password)

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，则有两个选项：

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

h2Database的默认详细信息
