JPA does not want to create a table in Spring Boot

Question

I have an entity

import lombok.Getter;
import lombok.Setter;

import javax.persistence.*;
import java.util.Date;

@Entity
@Table(name = "messages")
public class Message {

    @Id
    @GeneratedValue
    @Getter @Setter private Long id;

    @Getter @Setter private Long from;

    @Getter @Setter private Long to;
    ...

}

However, during the compilation it throws me exceptions

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory

Answer 1

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'from bigint, subject varchar(255), text varchar(255), to bigint, primary key (id' at line 1

from and to are reserved word in MySQL, you have to put them between two ``, so your query should look like this :

CREATE TABLE messages (
  `from` bigint, 
  subject varchar(255),
  `to` bigint, primary key (id)
);

To solve your problem and use the previouse query, you have to use @Column annotation to specify the name of the attribute between two `` like this :

@Column(name = "`from`")
@Getter @Setter private Long from;

@Column(name = "`to`")
@Getter @Setter private Long to;

---

But i would avoid this names in the name of columns, tables, ...

Answer 2

You need to specify the dialect so your server understand its using MYSQL

add this property to your properties file

 spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
