spring.datasource.initialize is deprecated

Question

I have a springboot application where I am trying to add following to application.properties file

spring.datasource.initialize=false

When I add this I see a warning as below:

I tried finding out what's the new property that replaces this deprecated property but in vain.

Can anybody help on this!

Having a reference to a migration guide would be great.

Answer 1

In Spring Boot 2.5, 'spring.datasource.initialization-mode' has been depracated as well: https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.5-Release-Notes#SQL-Script-DataSource-Initialization

you should use:

spring.sql.init.mode=always  

or

spring.sql.init.mode=never  

You can read more at:
https://docs.spring.io/spring-boot/docs/current/reference/html/howto.html#howto.data-initialization

Answer 2

As per the document

Spring Boot automatically creates the schema of an embedded DataSource. This behaviour can be customized by using the spring.datasource.initialization-mode property. For instance, if you want to always initialize the DataSource regardless of its type:

spring.datasource.initialization-mode=always

Look at this migration guide

Answer 3

As per Spring Boot Migration mentioned in Github

Basic DataSource initialization is now only enabled for embedded data sources and will switch off as soon as you’re using a production database. The new spring.datasource.initialization-mode (replacing spring.datasource.initialize) offers more control.

spring.datasource.initialization-mode=always
