Question

my classes seem to be mapped correctly (if I try persist an object it creates the table in the DB (if it’s missing)) and I can query succesfully, but I can’t get a newly created instance to be persisted to the DB.

I have show SQL queries in console, and it’s not generating the insert query, but it’s trying to select(max) id afterwards

Could someone please help me figure out why?

SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
        Session session = sessionFactory.openSession();
        User myUser = new User();
        myUser.setUserId("Acccc");
        myUser.setPassword("abc");
        session.save(myUser);

and class:

@Entity
@Table(name = "users")
@SuppressWarnings("serial")
public class User implements Serializable
{
    //Properties
    @Id
    @Column
    private int id;
    @Column
    private String userId;
    @Column
    private String password;

    //Getters
    public int getId() { return id; }
    public String getUserId() { return userId; }
    public String getPassword() { return password; }

    //Setters
    public void setId(int id) { this.id = id; }
    public void setUserId(String userId) { this.userId = userId; }
    public void setPassword(String password) { this.password = password; }
}

and config:

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="nz.co.genesis.healthsafety.stripes.model.User" table="users">
    <id name="id" type="int" column="id" >
    </id>
    <property name="userId" type="java.lang.String" column="userId" not-null="false" length="45" />
    <property name="password" type="java.lang.String" column="password" not-null="false" length="45" />
</class>
</hibernate-mapping>

And DB:

id : PK NN AI
userId varchar45, default NULL
password varchar45, default: null

I don’t think you configuration of the Transaction Hibernate
