java - 使用 Java 实现安全的社交持久性

Question

我开始使用 play 2.1 for java 和 SecureSocial。目前，我正在尝试向注册/注册该站点的用户添加一些持久性，但我在尝试将使用 SecureSocial 将其示例中的数据保存/检索数据表示为持久性模型时遇到了问题。

网页上还说我们可以实现 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对象的示例会很好。

提前致谢。

Answer 1

我正在使用 ebean 来拯救用户。

我的用户类是这样的:

封装模型；

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 token 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
    );
}

最后但同样重要的是我的 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 play.Logger;
import scala.Option;
import scala.Some;
import securesocial.core.AuthenticationMethod;
import securesocial.core.Identity;
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);
        if(localToken != null) {
            localToken.delete();
        }
    }

    @Override
    public Identity doFind(UserId userId) {
        if (Logger.isDebugEnabled()) {
            Logger.debug("find...");
            Logger.debug(String.format("id = %s", userId.id()));
        }
        LocalUser localUser = LocalUser.find.byId(userId.id());
        if(localUser == null) return null;
        SocialUser socialUser = new SocialUser(new UserId(localUser.id, localUser.provider), 
            localUser.firstName, localUser.lastName, String.format("%s %s", localUser.firstName, localUser.lastName),
            Option.apply(localUser.email), null, new AuthenticationMethod("userPassword"),
            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()) {
            Logger.debug("findByEmailAndProvider...");
            Logger.debug(String.format("email = %s", email));
            Logger.debug(String.format("providerId = %s", providerId));
        }

            );  
            if (Logger.isDebugEnabled()) {
