I try to create auth via jwt token with this tutorial: https://www.callicoder.com/spring-boot-spring-security-jwt-mysql-react-app-part-1/

I cannot resolve this problem:

I'm new in spring and I don't know what is wrong. My springBootVersion is '2.1.2.RELEASE'. What should I change?

Answer 1

nested exception is org.hibernate.AnnotationException: @Column(s) not allowed on a @ManyToOne property: com.easythings.battleship.model.Game.board

It seems that you have put @Column annotation on your manyToOne field in entity class. Use @JoinColumn instead. (look at this question and hibernate docs)
