在 H2 控制台中找不到在 JAVA 中创建的 H2 数据库？

Question

Currently have a simple Java Program that creates an H2 Database like so:

public static void main(String[] args) {
try {
    Connection conn = null;
    Statement stm = null;
    Class.forName("org.h2.Driver");
    conn = DriverManager.getConnection("jdbc:h2:D:/H2db/test", "sa", "sa");
    stm = conn.createStatement();
} catch (SQLException | ClassNotFoundException e) {
    e.printStackTrace();
}

I see the files created within the directory. Yet, when attempting to access this same Database from the H2 Console ( localhost:8082 ) and input both jdbc:h2:D:/H2db/test and jdbc:h2:D:\H2db\test , I get an error saying:

Database `D:/H2db/test` not found, either pre-create it or 
allow remote database creation (not recommended in secure environments)

Anyone know why I cant access the Database through the console?

Answer 1

That piece of code is just for connection to a previously created database. To successfully connect to it you should create it first.

$ java -cp bin/h2-1.4.199.jar org.h2.tools.Shell
Welcome to H2 Shell 1.4.199 (2019-03-13)
Exit with Ctrl+C
[Enter]   jdbc:h2:mem:test
URL       jdbc:h2:D:/h2db/test
[Enter]   org.h2.Driver
Driver    
[Enter]   sa
User      
Password

Then and only then you'll be able to connect to it through your java application.
