Spring Boot 2.3 fails to start when spring.jpa.hibernate.ddl-auto equals to validate

Question

I have a Spring boot: 2.3.0.RELEASE application with Flyway: 6.4.1 and Hibernate: hibernate-core: 5.4.22.Final, hibernate-validator: 6.1.5.Final, hibernate-commons-annotations: 5.1.0.Final.

I tried searching for errors but cannot find a solution. I tried applying this answer , but whenever spring.jpa.hibernate.ddl-auto=validate is set, it doesn't work if I use none , drop-create value everything back to the norm.

I run MySQL 5.7 in Docker, and the database with tables is there.

The error is below:

ConfigServletWebServerApplicationContext: Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'requestMappingHandlerAdapter' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Unsatisfied dependency expressed through method 'requestMappingHandlerAdapter' parameter 1; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mvcConversionService' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.format.support.FormattingConversionService]: Factory method 'mvcConversionService' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'customerRepository' defined in org.cloudwheel.files.configuration.customer.persistence.CustomerRepository defined in @EnableJpaRepositories declared on JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration: Cannot resolve reference to bean 'jpaMappingContext' while setting bean property 'mappingContext'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaMappingContext': Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory; nested exception is org.hibernate.tool.schema.spi.SchemaManagementException: Schema-validation: missing table [my_files]

How can I debug this? I see many such issues, but none of the solutions worked for me.

NOTE: The table my_files is present. I can verify this both via IntelliJ and MySQL Workbench. Also, I don't want to downgrade if possible.

UPDATE:

I am sure that a database isn't a problem:

Answer 1

The exception says org.hibernate.tool.schema.spi.SchemaManagementException: Schema-validation: missing table [my_files] .

You say that the database my_files is present, but hibernate needs a table my_files to be present - for example you used annotation @Table(name = "my_files") or you have entity with name MyFiles.

Check whether the database contains the table my_files .

Answer 2

As @M.Deinum mentioned in his comments Flyway and Hibernate might not have been connected to the same datasource. In my case, it was because of hibernate.temp.use_jdbc_metadata_defaults=true . As soon as I removed this property, everything started working.
