Spring Jpa Repository crash on insert - spring

Question

I'm trying to implement a repository for refresh JWT tokens and I can't save my token in postgresql.
My entity :
#Entity(name = "refreshtoken")
public class RefreshToken {
#Id
#GeneratedValue(strategy = GenerationType.SEQUENCE)
private long id;
#Column(nullable = false, unique = true)
private String user;
#Column(nullable = false, unique = true)
private String token;
#Column(nullable = false)
private Instant expiryDate;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getUser() {
return user;
}
public void setUser(String user) {
this.user = user;
}
public String getToken() {
return token;
}
public void setToken(String token) {
this.token = token;
}
public Instant getExpiryDate() {
return expiryDate;
}
public void setExpiryDate(Instant expiryDate) {
this.expiryDate = expiryDate;
}
The refresh token is initialised with the right values.
The logs are
Hibernate: select nextval ('hibernate_sequence') Hibernate: insert
into refreshtoken (expiry_date, token, user, id) values (?, ?, ?, ?)

I have spring.jpa.hibernate.ddl-auto= update
I created refreshtoken table manualy but I also noticed that after it crashed, all field are created except user.
Any help would be welcome, thanks

Answer 1

Like Manuel pointed out in the comment, user is a reserved word in postgresql

Answer 2

"user" is a reserved keyword for Postgresql
