Why Isn't Spring Boot Automatically Creating My Database Schema?

Troubleshooting Spring Boot Database Schema Creation

Problem: Spring Boot is unable to automatically create the database schema upon startup.

Potential Causes and Solutions:

1. Entity Location: Ensure that your entity classes are located in the same package (or a sub-package) as your class annotated with @EnableAutoConfiguration.
2. Hibernate Configuration: Replace your existing Hibernate-specific configuration with the following optimized settings:

spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect
spring.jpa.hibernate.ddl-auto=update
spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=test
spring.datasource.password=

3. Application Properties: Verify that your application.properties file is placed in the correct location: src/main/resources.
4. Database Dialect: Ensure that the specified database dialect (spring.jpa.database) is correct for your type of database. If the wrong dialect is set, Spring Boot might attempt to connect to an in-memory database and fail to update the schema.
