I have a problem when I click on update a window appears and there I update the data but instead of updating it I create another record I do not know what to do next I leave the code:

Model

user class

@Entity public class User extends AbstractPersistable {

private transient Long id;

private String usuarioId;

private String usuarioNombre;

private String clave;

@ManyToOne
@JoinColumn(name="rol_id")
private Rol rol;


@OneToMany(targetEntity=Direccion.class, mappedBy="usuario", fetch=FetchType.LAZY,cascade=CascadeType.ALL)
private Set<Direccion> direcciones;



public Long getId() {
    return id;
}

public void setId(Long id) {
    this.id = id;
}

public String getUsuarioId() {
    return usuarioId;
}

public void setUsuarioId(String usuarioId) {
    this.usuarioId = usuarioId;
}

public String getUsuarioNombre() {
    return usuarioNombre;
}

public void setUsuarioNombre(String usuarioNombre) {
    this.usuarioNombre = usuarioNombre;
}

public String getClave() {
    return clave;
}

public void setClave(String clave) {
    this.clave = clave;
}

public Rol getRol() {
    return rol;
}

public void setRol(Rol rol) {
    this.rol = rol;
}

en la clase direccion

@Entity public class Address extends AbstractPersistable {

private String ciudad;
private String distrito;
private String pais;

private transient Long usuarioId;


@ManyToOne
@JoinColumn(name="usuario_id")
private Usuario usuario;




public Long getUsuarioId() {
    return usuarioId;
}
public void setUsuarioId(Long usuarioId) {
    this.usuarioId = usuarioId;
}
public String getCiudad() {
    return ciudad;
}
public void setCiudad(String ciudad) {
    this.ciudad = ciudad;
}
public String getDistrito() {
    return distrito;
}
public void setDistrito(String distrito) {
    this.distrito = distrito;
}
public String getPais() {
    return pais;
}
public void setPais(String pais) {
    this.pais = pais;
}
public Usuario getUsuario() {
    return usuario;
}
public void setUsuario(Usuario usuario) {
    this.usuario = usuario;
}

In your case you have to make sure that the @PostMapping ("/ add") correctly receives the object you want to save and that it has an established ID when it is the case of updating, I'll give you a simple example that works:

Note: previously you had to upload in a form everything related to your case with the address and your user so that when you click on save you can call this function from the view.

    @PostMapping("/agregar")
    public String agregar(@Valid Cliente cliente, Model model) {

        String debug= (cliente.getId() != null)? "Cliente editado con éxito!" : "Cliente creado con éxito!";

        clienteService.save(cliente); //Crea o actualiza automaticamente

        return "listar";
    }

It is the same method to update as to add so it depends on the user id.

public interface IClienteService {
    public void save(Cliente cliente);
}

You will have the following function in the implementation of IClienteService :

@Service
public class ClienteServiceImpl implements IClienteService{
    @Override
    @Transactional
    public void save(Cliente cliente) {
        clienteDao.save(cliente);
    }
}

And the DAO will be as follows, very very simple:

public interface IClienteDao extends JpaRepository<Cliente, Long> {}

Once updated you will only have to redirect to the view where you make the list of the object that you have just updated.

Greetings.

I already got the update button and add

In the Model I had to change the following code:

@Entity public class Address {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;

private transient Long usuarioId;

private String ciudad;
private String distrito;
private String pais;




public Long getId() {
    return id;
}
public void setId(Long id) {
    this.id = id;
}
@ManyToOne
@JoinColumn(name="usuario_id")
private Usuario usuario;




public Long getUsuarioId() {
    return usuarioId;
}
public void setUsuarioId(Long usuarioId) {
    this.usuarioId = usuarioId;
}
public String getCiudad() {
    return ciudad;
}
public void setCiudad(String ciudad) {
    this.ciudad = ciudad;
}
public String getDistrito() {
    return distrito;
}
public void setDistrito(String distrito) {
    this.distrito = distrito;
}
public String getPais() {
    return pais;
}
public void setPais(String pais) {
    this.pais = pais;
}
public Usuario getUsuario() {
    return usuario;
}
public void setUsuario(Usuario usuario) {
    this.usuario = usuario;
}
