在不知道登录名和密码的情况下连接到数据库

Question

My project interacts with database (executes usual CRUD operations). For connection to database I wrote login and password in application.properties:

spring.datasource.username=root
spring.datasource.password=root

This approach works only if I work on my desktop with my account in mysql.

I want to transfer my project to another desktop with another account in mysql. I want the person who will get my project can run my app with one click, without writing his username/password in application.properties.

I don't know the username and password of this person. So I cann't write its to application.properties.

I researched this problem and found this question: Start spring-boot app without depending on username and password for Database oracle?

The author of this question wants the person will pass authentication in web. But I want there won't necessity for person to enter any data except just run the program.

Is there any way to achieve it?

Answer 1

There are ways that you can use:

1. The user has personal credentials on the database and needs to use them. Here you can either request them at runtime or have them preconfigured in some properties file. But it seems you do not like any of these scenarios.
2. The user may have personal credentials on the application but there is an application account for the database. In this case the user logs on to your application, which can even connect to the database to verify the credentials. Or the user does not have to authenticate on the application and can use it straight away.
3. The user has the whole application running locally on his computer - regardless whether it is a web application or a fat client. In this case the user can directly edit the properties file on his computer and store the credentials. Or alternatively enter them on the GUI so it stores the values on his behalf.

Any more scenarios to think of?
