问题
I started using play 2.1 for java and SecureSocial. Currently I'm trying to add some persistance to the Users that register/sign up to the site but I'm having trouble trying to represent the model that uses SecureSocial to save/retrieve data in their examples to a persistence model.
Also in the web page says that we can implement SocialUser Object, but I really don't know how I can use it because is a scala object. An example of how could I call or extend that Object would be nice.
Thanks in advance.
回答1:
I am using ebean to save the users.
My user class looks like this:
package models;
import javax.persistence.Entity;
import javax.persistence.Id;
import play.db.ebean.Model;
@Entity
public class LocalUser extends Model {
private static final long serialVersionUID = 1L;
@Id
public String id;
public String provider;
public String firstName;
public String lastName;
public String email;
public String password;
public static Finder<String, LocalUser> find = new Finder<String, LocalUser>(
String.class, LocalUser.class
);
@Override
public String toString() {
return this.id + " - " + this.firstName;
}
}
My token class:
package models;
import java.util.Date;
import javax.persistence.Entity;
import javax.persistence.Id;
import play.db.ebean.Model;
@Entity
public class LocalToken extends Model {
private static final long serialVersionUID = 1L;
@Id
public String uuid;
public String email;
public Date createdAt;
public Date expireAt;
public boolean isSignUp;
public static Finder<String, LocalToken> find = new Finder<String, LocalToken>(
String.class, LocalToken.class
);
}
And last but not least my UserService:
package services;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;
import org.joda.time.DateTime;
