在JSF中使用实体作为Backing Beans是否有意义?
@Entity
@ManagedBean
@ViewScoped
public class User {
private String firstname;
private String lastname;
@EJB
private UserService service;
public void submit() {
service.create(this);
}
// ...
}
或者是把它们分开保持独立,在最后将数据从后端Bean传输到实体中,这样是否更好呢?
@ManagedBean
@ViewScoped
public class UserBean {
private String firstname;
private String lastname;
@EJB
private UserService service;
public void submit() {
User user = new User();
user.setFirstname(firstname);
user.setLastname(lastname);
service.create(user);
}
// ...
}
