and my application.properties:

spring.datasource.url=jbdc:mysql://localhost:3306/employeemanager
spring.datasource.username=root
spring.datasource.password=letmein
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect

Answer 1

On Spring Boot 2.5.X data.sql scripts are now run before Hibernate is initialized. If you want to use data.sql to populate a schema created by Hibernate try adding the following to your application.properties spring.jpa.defer-datasource-initialization=true.

Answer 2

# mySQL configuration
spring.datasource.url=jbdc:mysql://localhost:3306/employeemanager
there's a typo, its supposed to be jdbc not jbdc

Answer 3

As I do remember, I was facing similar issue during integration.
Could you please validate your pom.xml and application.properties/application.yaml configurations as below.

Application Properties - application.yaml
spring:
datasource:
url: jdbc:mysql://localhost:3306/bootdb
username: root
password: admin
jpa:
hibernate.ddl-auto: update
show-sql: true
user.datasource.driver-class-name: com.mysql.jdbc.Driver
For more detail you may go through following working examples:

https://thebasictechinfo.com/java-8/spring-boot-spring-security-with-database-authentication-mysql-rest-api-example/
Also, could you try with following properties.
spring.datasource.jdbcUrl=jdbc:mysql://localhost/bootdb?useSSL=false
spring.datasource.username=root
spring.datasource.password=admin
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
Enjoy :)
