Insert data into table with jsf,Hibernate jpa

Question

I’m having problems, in the project I’m developing in jsf using jpa and Hibernate. I am not able to register the customer data in my database as I can relate the registration ?

Code

EntityManagerFactory factory = Persistence.createEntityManagerFactory("WebApplication3PU");

EntityManager manager = factory.createEntityManager();
ClienteWeb cli= new ClienteWeb(); 
public ClienteWeb cadastrarCliente(){
           manager.getTransaction().begin();    
   manager.persist(cli);
    manager.getTransaction().commit();  
manager.close();

return cli;
    }

Customer registration

public ClienteWeb cadastrarCliente(){

manager.getTransaction().begin();    
   manager.persist(cli);
    manager.getTransaction().commit();  
manager.close();

return cli;
    }

Method with objects returned from the jsf form.

public Cliente montaCliente(){
    Cliente cli= new Cliente();
    cli.setNome(cli.getNome());
    cli.setEmail(cli.getEmail());
    cli.setSexo(cli.getSexo());
    cli.setEstado(cli.getEstado());
    cli.setSenha(cli.getSenha());
    cli.setData(cli.getData());
    cli.setCelular(cli.getCelular());
    cli.setCpf(cli.getCpf());
    cli.setCidade(cli.getCidade());
    cli.setCep(cli.getCep());
    cli.setConfirmar(cli.getConfirmar());
    cli.setRua(cli.getRua());
    cli.setNumero(cli.getNumero());
    cli.setBairro(cli.getBairro());
    cli.setUf(cli.getUf());
    cli.setLogin(cli.getLogin());

    return cli;
}

My doubt is how I will put the values of the objects typed by the user that I pick up with my class of magnedBean client and put in the method cadastrarCliente, being that in it I persist the database of my class of entiade Clienteweb ?

Answer 1

Since you didn’t post your view code, I took the liberty of creating some code snippets:

---

cadastraCliente.xhtml

<form>
    <p:inputText value="#{clienteMB.cliente.nome}" />
    <p:inputText value="#{clienteMB.cliente.idade}" />
    <p:inputText value="#{clienteMB.cliente.endereco}" />
    <p:commandButton actionListener="#{clienteMB.cadastraCliente}" />
</form>

Clientemb

@ManagedBean
public class ClienteMB {

    private Cliente cliente;
    private ClienteDAO dao;

    public ClienteMB() {
        this.cliente = new Cliente();
        this.dao = new ClienteDAO();
    }

    public void cadastraCliente() {
        dao.cadastraCliente(this.cliente);
    }

    public Cliente getCliente() {
        return this.cliente;
    }

    public void setCliente(Cliente cliente) {
        this.cliente = cliente;
    }
}

---

Clientele

public class ClienteDAO() {

    EntityManagerFactory factory;
    EntityManager manager;

    public ClienteDAO() {
        this.factory = Persistence.createEntityManagerFactory("WebApplication3PU");
        this.manager = factory.createEntityManager();
    }

    public void cadastraCliente(Cliente cliente) {
        manager.getTransaction().begin();    
        manager.persist(cli);
        manager.getTransaction().commit();  
        manager.close();
    }
}

Explanation

In order to be able to transmit the data from the page to the bank, you must first pass the data from the view (xhtml) to the controller (Managedbean).

This is done by the attribute cliente class ClienteMB.

JSF can populate this attribute with the values filled when we inform on inputText the property value="#{clienteMB.cliente.nome}", for example. This way the value entered in this field will be "set" in the property nome of cliente of ClienteMB.

After that it is necessary to prepare the class ClienteDAO for her to receive a Cliente to persist (save to bank).

This is done through the method public void cadastraCliente(Cliente cliente). Note that this method receives a parameter called cliente of the kind Cliente.

In the ClienteMBthe attribute cliente is populated by input values. There we call the method the registered method passing, precisely, the attribute cliente as a parameter, thus: cadastraCliente(cliente).

Finally, the registration is performed when the user clicks on the button <p:commandButton>, who calls the method cadastraCliente() of ClienteMB.

This way it is possible to persist in the database the data from the page.

---

Points of Attention

1. It is essential that the attribute cliente of ClienteMB have your methods getter and setter. It is through these methods that JSF communicates to view with the controller

2. There are several ways to pass values of the view to the controller. That was one example

3. The DAO is without any exception treats. Consider strongly, use try catch finally or try-with-resources, if using Java 7 or higher.
