Estou fazendo a aula começando com spring data JPA, após ter adicionado os @Entitys e @Ids fui rodar o codigo, porem aparece a seguinte falha no LocalContainerEntityManagerFactoryBean: Failed to initialize JPA EntityManagerFactory: No identifier specified for entity: com.RestApi.RestAPI.modelo.Topico
seguidos por esses erros: ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is org.hibernate.AnnotationException: No identifier specified for entity: com.RestApi.RestAPI.modelo.Topico
o.s.b.f.support.DisposableBeanAdapter : Invocation of destroy method failed on bean with name 'inMemoryDatabaseShutdownExecutor': org.h2.jdbc.JdbcSQLNonTransientConnectionException: Database is already closed (to disable automatic closing at VM shutdown, add ";DB_CLOSE_ON_EXIT=FALSE" to the db URL) [90121-200]
Alguem saberia o que está acontecendo?
