如何使用Play 2.0和SecureSocial持久保存用户注册

Question

我正在使用带有SecureSocial的 Play 2.0.4 .我想使用UsernamePasswordProvider将用户注册持久保存到数据库.

我对Java和Play Framework比较陌生,所以我不确定如何完成这项工作.我创建了一个名为"用户"的简单模型,但不知道如何从这里走得更远.

我希望那里的某些人能够帮助我,我确信之前已经完成了.首先十分感谢!

@Entity
public class User extends Model {
  //
}

假设您已经为使用SecureSocial配置了Play2.0,您可以从这个问题开始:使用Java播放SecureSocial Persistance 我已经设法通过一些小的修正来完成这项工作:

您需要对用户进行一些本地表示,以便将用户信息存储到持久层.我使用了Ebean和一个简单的LocalBean.像这样的东西会这样做:

package models;

import java.util.List;
import javax.persistence.Entity;
import javax.persistence.Id;
import play.db.ebean.Model;
import play.data.validation.*;
import play.data.format.*;

@Entity
public class LocalUser extends Model {

    @Id
    public String id;
    public String name;
    public String email;
    public String password;
    public String provider;
        public String firstName;
        public String lastName;

        public static Finder<String, LocalUser> find = new Finder<String, LocalUser (String.class,LocalUser.class);


/**
 * Retrieve a User using an email.
 */
    public static LocalUser findByEmail(String email) {
        return find.where().eq("email", email).findUnique();
    }
}

对于我的Token类,我使用与上述问题中提出的相同:

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
    );
}

对于UserService,我不得不对上述问题进行一些小修改,使其适用于较新版本的SecureSocial,其中user().id属性被identityId()替换:

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.IdentityId;
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) {
    public Identity doFind(IdentityId identityId){
        if (Logger.isDebugEnabled()) {
            Logger.debug(String.format("finding by Id = %s", identityId.userId()));

        }
        LocalUser localUser = LocalUser.findByEmail(identityId.userId());
        if(localUser == null) return null;
        SocialUser socialUser = new SocialUser(new IdentityId(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) {
        List<LocalUser> list = LocalUser.find.where().eq("email", email).eq("provider", providerId).findList();
        if(list.size() != 1){
            Logger.debug("found a null in findByEmailAndProvider...");
            return null;
        }
        LocalUser localUser = list.get(0);
        SocialUser socialUser = 
                new SocialUser(new IdentityId(localUser.email, 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))
                   );  
        return socialUser;
    }

    @Override
    public Token doFindToken(String token) {
        if (Logger.isDebugEnabled()) {
            Logger.debug("findToken...");
            Logger.debug(String.format("token = %s", token));
        }
        LocalToken localToken = LocalToken.find.byId(token);
        if(localToken == null) return null;
        Token result = new Token();
        result.uuid = localToken.uuid;
        result.creationTime = new DateTime(localToken.createdAt);
        result.email = localToken.email;
        result.expirationTime = new DateTime(localToken.expireAt);
        result.isSignUp = localToken.isSignUp;
        if (Logger.isDebugEnabled()) {
            Logger.debug(String.format("foundToken = %s", result));
        }
        return result;
    }

    @Override
    public Identity doSave(Identity user) {
        if (Logger.isDebugEnabled()) {
            Logger.debug("save...");
            Logger.debug(String.format("user = %s", user));
        }
        LocalUser localUser = null;
        //localUser = LocalUser.find.byId(user.id().id());
        localUser = LocalUser.find.byId(user.identityId().userId());

        if (localUser == null) {
            Logger.debug("adding new...");
            localUser = new LocalUser();
            //here was localUser.id = user.id().id();
            localUser.id = user.identityId().userId();
            localUser.provider = user.identityId().providerId();
            localUser.firstName = user.firstName();
            localUser.lastName = user.lastName();
            localUser.email = user.email().get();
            localUser.password = user.passwordInfo().get().password();
            localUser.save();
        } else {
            Logger.debug("existing one...");
            localUser.id = user.identityId().userId();
            localUser.provider = user.identityId().providerId();
            localUser.firstName = user.firstName();
            localUser.lastName = user.lastName();
            localUser.email = user.email().get();
            localUser.password = user.passwordInfo().get().password();
            localUser.update();
        }
        return user;
    }

    @Override
    public void doSave(Token token) {
        LocalToken localToken = new LocalToken();
        localToken.uuid = token.uuid;
        localToken.email = token.email;
        try {
            SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            localToken.createdAt = df.parse(token.creationTime.toString("yyyy-MM-dd HH:mm:ss"));
            localToken.expireAt = df.parse(token.expirationTime.toString("yyyy-MM-dd HH:mm:ss"));
        } catch (ParseException e) {
            Logger.error("SqlUserService.doSave(): ", e);
        }
        localToken.isSignUp = token.isSignUp;
        localToken.save();
    }
}

而已.请注意,使用Bcrypt密码存储密码,因此您需要哈希密码以使其正常工作.获取哈希传递的最简单方法是使用SecureSocial提供的注册过程.

希望这可以帮助.
