Mappare risorse Hibernate

**Ironmax** · 17-10-2016, 11:46

Provo a postare tutto il progetto:

codice:

package org.massimo.dettagliUser;
import javax.persistence.Entity;
import javax.persistence.Id;

@Entity
public class UtenteUser {
    @Id
    private int userId;
    private String userName;

    public UtenteUser() {
        // TODO Auto-generated constructor stub
    }

    public UtenteUser(int userId, String userName) {
        super();
        this.userId = userId;
        this.userName = userName;
    }

    public int getUserId() {
        return userId;
    }

    public void setUserId(int userId) {
        this.userId = userId;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

}

Errori di parsing:
