如何在Eclipse中的Java项目中创建H2数据库？

Question

我想在Eclipse中的简单java项目中创建一个嵌入式H2数据库.我如何以编程方式执行此操作并将db打包到我的代码中？我为此尝试了一个SO帖子并在我的代码中出错.

代码 -

public static void main(String[]args){

    JdbcDataSource ds = new JdbcDataSource();
    ds.setURL("jdbc:h2:˜/test");
    ds.setUser("sa");
    ds.setPassword("sa");
    try {
        Connection conn = ds.getConnection();
    } catch (SQLException e) {
        e.printStackTrace();
    }

}

错误 -

org.h2.jdbc.JdbcSQLException: A file path that is implicitly relative to the 
current working directory is not allowed in the database URL "jdbc:h2:˜/test". 
Use an absolute path, ~/name, ./name, or the baseDir setting instead. [90011-181]

我看到了这个链接 - https://groups.google.com/forum/#!msg/h2-database/SlSwte0DLSU/eWj0UaejdkEJ以及我的H2数据库文件在哪里？.我不清楚如何在我的Windows PC上获得测试数据库的确切路径.

我如何首先访问测试数据库,然后在我的java项目中创建另一个数据库？

谢谢.

你使用了错误的角色.你需要使用~(代字号)并且你有用˜(我不知道它是什么,但它不是代字号).
