Question

我正在使用Play 2.0.4和 SecureSocial 。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。

我希望有人可以帮助我，我确信之前已经完成了。非常感谢提前！

@Entity
public class User extends Model {
  //
}

假设您已将Play2.0配置为使用SecureSocial，您可以从这个问题开始：Play SecureSocial Persistance with Java 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。这样的事情会做到：

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();
    }
}

对于我的令牌课程，我使用的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做一些小修改，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;

        }
        List<LocalToken> list = LocalToken.find.where().lt("expireAt", new DateTime().toString()).findList();
        for(LocalToken localToken : list) {
            localToken.delete();
        }
    }

        }
        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) {

            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();

            localUser.firstName = user.firstName();
            localUser.lastName = user.lastName();

            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();
    }
}

就是这样。请注意，使用Bcrypt密码存储密码，因此您需要哈希密码才能使用密码。获取哈希传递的最简单方法是使用SecureSocial提供的注册过程很简单。

希望这有帮助。

您需要实现UserService的子类并在play.plugins文件中注册该插件，以便SecureSocial选择它。从UserService实现中，您将使用模型类来保存/查找信息。

有一个带有示例UserService的拉取请求（虽然在Scala中），您可以将其用作指南：https://github.com/jaliss/securesocial/pull/163。

您还可以使用示例中的InMemoryUserService作为起点，并将其使用的哈希映射替换为对模型对象的调用以保留/检索内容。

在上面的pull请求中，AuthenticatorStore文件的目的是什么？
