什么是h2数据库的jdbc连接字符串？

Question

I'm trying to connect to an h2 database on my local machine to create a sql DataSource object. I'm running windows and i'm having some issues defining the path to the data file in my projects app.properties file.

Say the path to the local directory data file is:

D:\projects\myproject\data\project

How would one go about defining a connection url for this?

I've tried the many things including the following:

project.db.url = jdbc:h2:tcp://localhost\\\\D:\\projects\\myproject\\data\\project

Then I thought maybe it's the JDBC URL that's the issue, so I tried:

project.db.url = jdbc:h2:tcp:\\\\localhost\\\\D:\\projects\\myproject\\data\\project

Answer 1

As per documentation , default JDBC connection string is

jdbc:h2:~/test  

And, for TCP connection

jdbc:h2:tcp://localhost/~/test  

==Update==

But, if you wanted to create/read h2 database to/from specific folder, then it should be

 jdbc:h2:tcp://localhost/<path_to_database>

That means,

jdbc:h2:tcp://localhost/D:/myproject/data/project-name

Thanks @Sam for sharing info.

Change application.properties to the following:

spring.jpa.open-in-view=true

spring.datasource.url=jdbc:h2:mem:testdb

spring.datasource.driverClassName=org.h2.Driver

spring.datasource.username=sa

spring.datasource.password=

Set H2 Console to the following:

jdbc:h2:mem:testdb
