Mapping classes HIBERNATE

Question

Guys, I have a question about an exercise that was passed on campus recently. I have to map classes with JPA, Hibernate and I’m having a little difficulty in mapping the relationships of these classes.

1. The problem is this, the exercise is about a Football Game where we have the classes Player, Team, Coach, Judge, Game.

2. In the relationship would be Player has a Team and the Team has several Players. So far so good!

3. How I mapped this example, and I would like you to help me because I’m not being able to generate my DB with this mapping.

   This is the Player class where I refer to his Team. @ManyToOne(fetch = FetchType.EAGER) @JoinColumn(name="time_Cod", insertable=true,updatable=true) @Fetch(FetchMode.JOIN) @Cascade(org.hibernate.annotations.CascadeType.SAVE_UPDATE) private Time time;

   And my Multi-player Team.

   @OneToMany(mappedBy="Time",fetch = FetchType.LAZY) @Cascade(CascadeType.ALL) private ArrayList<Jogador> jogador;

4. There are other relationships, but, if I put here you would end up doing my kkkk activity then only this little help would be wonderful.

5. If you need more information, please let me know, and thank you!

EDIT 3 - Code

public static void main(String[] args) {


    try {


        EntityManagerFactory factory = Persistence.createEntityManagerFactory("conexaoDB");
        factory.close();


      System.out.println("Gerado");     
    } catch (Exception e) {
      System.out.println("Não Gerado: "+e.getMessage());
    }

}

Answer 1

Well, in your persistence.xml missing vc add your entities in tags<class> </class>, you just have to publish the Fully Qualified name ex class: <class>br.com.financas.modelo.Conta</class> in the persistence.xml.

In your case you will give a Warning saying that his preview is obsolete, just update the configuration of the persistence.xml, with the seguite preview: Ex:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" 
xmlns="http://xmlns.jcp.org/xml/ns/persistence" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence 
http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
</persistence>`
