使用Java玩SecureSocial Persistance [英] Play SecureSocial Persistance with Java

问题描述

我开始使用play 2.1 for java和SecureSocial。目前我正在尝试为注册/注册该站点的用户添加一些持久性，但我无法尝试使用SecureSocial将示例中的数据保存/检索到持久性模型。

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.

同样在网页上说我们可以实现SocialUser对象，但我真的不知道如何使用它，因为它是一个scala对象。我如何调用或扩展该Object的示例将很好。

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.

提前致谢。

推荐答案

我使用ebean来保存用户。

I am using ebean to save the users.

我的用户类看起来像这样：

My user class looks like this:

包模型;

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;
    }
}

我的令牌类：

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
    );
}

最后但并非最不重要的是我的UserService：

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;

import models.LocalToken;
import models.LocalUser;
import play.Application;

import securesocial.core.PasswordInfo;
import securesocial.core.SocialUser;
import securesocial.core.UserId;
import securesocial.core.java.BaseUserService;
import securesocial.core.java.Token;

public class SqlUserService extends BaseUserService {

    public SqlUserService(Application application) {
        super(application);
    }

    @Override
    public void doDeleteExpiredTokens() {
        if (Logger.isDebugEnabled()) {
            Logger.debug("deleteExpiredTokens...");
        }
        List<LocalToken> list = LocalToken.find.where().lt("expireAt", new DateTime().toString()).findList();
        for(LocalToken localToken : list) {
            localToken.delete();
        }
    }

    @Override
    public void doDeleteToken(String uuid) {
        if (Logger.isDebugEnabled()) {
            Logger.debug("deleteToken...");
            Logger.debug(String.format("uuid = %s", uuid));
        }
        LocalToken localToken = LocalToken.find.byId(uuid);

    @Override

        }
        LocalUser localUser = LocalUser.find.byId(userId.id());
        if(localUser == null) return null;
        SocialUser socialUser = new SocialUser(new UserId(localUser.id, localUser.provider),

            null, null, Some.apply(new PasswordInfo("bcrypt", localUser.password, null))
        );  
        if (Logger.isDebugEnabled()) {
            Logger.debug(String.format("socialUser = %s", socialUser));
        }
        return socialUser;
    }


    @Override
    public Identity doFindByEmailAndProvider(String email, String providerId) {
        if (Logger.isDebugEnabled()) {
