org.postgresql.util.PSQLException: ERROR: column user0_.id does not exist - Hibernate

Question

I have a model class that is mapped to a postgres database using hibernate. My model class is:

@Entity
@Table(name=\"USER\")
public class User {

    @Id 
    @G         


        

Answer 1

For people getting this exception ,In postgres Whenever you write an Entity Class try to associate it with the correct schema (where your table is present), like this:

@Entity
@Table(name = "user", schema = "users_details")
public class User implements Serializable{

    @Column(name = "id")
    Long id;    //long is not recommended

   // Other data
}

As @YCF_L has said Don't use Upper_case letters in a table name or column name otherwise you will get this exception.

This convention becomes more important when their is a scenario where you have to auto generate the tables from entity classes or vice-versa.
