Spring boot Embedded Derby not working in the latest version. - spring

Question

I have used Embedded derby earlier in my spring boot projects. But now when i created the project through Spring Initializr with the derby dependency. I get the below error :
Schema 'SA' does not exist
followed by org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL via JDBC Statement
When i tried running the earlier project that i had created, the Derby is working just fine.
PFB the console for the earlier project :

The difference i can find between the two is that in the current log(abv log) it says that the
com.zaxxer.hikari.util.DriverDataSource : Registered driver with
driverClassName=org.apache.derby.jdbc.EmbeddedDriver was not found,
trying direct instantiation.
Let me know if we need to configure something apart from the below dependency for enabling this derby. Note- I dint do anything apart from maven dependency in the previous project.
Maven dependency :
<dependency>
<groupId>org.apache.derby</groupId>
<artifactId>derby</artifactId>
<scope>runtime</scope>
</dependency>

Answer 1

Please configure you JPA Configuration as per your requirement. I've configured as below. You need to add below configuration in application.properties file.
# PROFILES
spring.profiles.active=dev
# JPA (JpaBaseConfiguration, HibernateJpaAutoConfiguration)
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.database=default
spring.jpa.show-sql=true
# DATASOURCE (DataSourceAutoConfiguration & DataSourceProperties)
spring.datasource.continue-on-error=false
spring.datasource.generate-unique-name=false

Answer 2

add
spring.jpa.hibernate.ddl-auto=update
to your application.properties
it is by default create-drop.

Answer 3

The default driver used by derby is org.apache.derby.jdbc.AutoloadedDriver, but springboot and other framework choice org.apache.derby.jdbc.EmbeddedDriver.
It causes the driver to be unable to find the driver when using the datasource for the first time.
About Schema 'SA' does not exist.
I think that you use the other tool connect the derby, such as ij. And the jdbc url they use is the same. It looks like the same database connected, but it's not actually.
This is the key to the problem.

Answer 4

Added this in appplication.properties and worked
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.database=default
spring.jpa.show-sql=true

Answer 5

I've added below property in application.properties, it worked!
spring.jpa.hibernate.ddl-auto=update
