问题描述
我使用以下URL用代码创建了一个H2数据库:
I created a H2 database with my code with this URL:
我的代码可以创建表,执行查询.如果手动打开文件,则可以成功查看其内容并查看创建查询等
My code can create tables, perform queries. If I open the file manually, I can successfully see its content and view the create queries etc
但是,当我尝试通过Web界面使用H2控制台时,看不到数据库.而是,Web控制台在C:/data/fixed.db.mv.db
处创建另一个空数据库.我只是无法加载我的数据库.
However, when I try to use H2 console with the web interface, I can't see the database. Instead, the web console create another empty database located here C:/data/fixed.db.mv.db
. I just can't load my database.
我想念什么?

我的代码使用H2 1.3.175
Web控制台H2 1.4.178
My code uses H2 1.3.175
The web console H2 1.4.178
推荐答案
最后,我解决了我的问题...
Finally I solved my problem...
从1.4.x开始,H2使用MV_STORE(请参见此处和Thomas Mueller的评论).显然,Web控制台尝试自动附加.mv.db
扩展名.即使已经有一个扩展名为h2.db
的文件.
Since 1.4.x, H2 uses MV_STORE (see SO answer here and Thomas Mueller comment).Apparently, the web console tries to append automatically a .mv.db
extension. Even if there is already a file with the h2.db
extension.
因此,我将代码的H2版本从1.3.175升级到1.4.178,最后,我可以看到我的数据了...
So , I upgrade the H2 version of my code from 1.3.175 to 1.4.178 and finally, I can see my data...

这是 @devdanke 提出的替代解决方案:
EDIT
Here is an alternative solution proposed by @devdanke:
例如,您将以类似以下代码的结尾:
For example, you would end with a code similar to:
Class.forName("org.h2.Driver");
Connection conn = DriverManager.getConnection( //
"jdbc:h2:file:C:\\my\\java\\projects\\test;mv_store=false" //
);
这篇关于在Web控制台中看不到我的H2数据库的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
