Error creating table with Spring Boot and Postgres - spring

Question

I am trying to create an application using Spring and Postgres. Currently I have 3 Entities: User, Role and UserRole.
User
import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import javax.persistence.*;
#Data
#Entity
#Builder
#AllArgsConstructor
public class User {
#Id
#GeneratedValue(strategy= GenerationType.IDENTITY)
#Column(name = "user_id", nullable = false)
private Long id;
#Column(name = "username", nullable = false, unique = true)
private String username;
#Column(name = "password", nullable = false)
private String password;
#Column(name = "name", nullable = false)
private String firstName;
#Column(name = "lastName", nullable = true)
private String lastName;
#Column(name = "gender", nullable = false)
private char gender;
#Column(name = "email", nullable = true)
private String email;
public User() {}
public User(String username, String password, String firstName, String lastName, char gender, String email) {
this.username = username;
this.password = password;
this.firstName = firstName;
this.lastName = lastName;
this.gender = gender;
this.email = email;
}
}
Role
import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import javax.persistence.*;
#Data
#Entity
#Builder
#AllArgsConstructor
public class Role {
#Id
#GeneratedValue(strategy= GenerationType.IDENTITY)
#Column(name = "role_id", nullable = false)
private Long id;
#Column(name = "name", nullable = false)
private String name;
#Column(name = "description", nullable = false)
private String description;
public Role () {}
public Role (String name, String description) {
this.name = name;
this.description = description;
}
}
UserRole
import lombok.AllArgsConstructor;
import lombok.Data;
import javax.persistence.*;
#Data
#Entity
#AllArgsConstructor
public class UserRole {
#Id
#GeneratedValue(strategy= GenerationType.IDENTITY)
#Column(name = "user_role_id")
private Long id;
#OneToOne
#JoinColumn(name = "user_id")
private User user;
#OneToOne
#JoinColumn(name = "role_id")
private Role role;
public UserRole () {}
public UserRole (User user, Role role) {
this.user = user;
this.role = role;
}
}
When running the application, Role and UserRole tables are created in the database correctly, but its not the case with User table. I will appreciate your help :).

Answer 1

user is a reserved keyword in postgresql because of which it is not allowing to create the table with this name. Try with another name.
