Social Login in Spring MVC mit Spring Social Security

1- Die Tabelle

Zuerst sollen Sie die Tabelle erstellen
** ORACLE **
-- Create table
create table USERCONNECTION
(
USERID         VARCHAR2(255) not null,
PROVIDERID     VARCHAR2(255) not null,
PROVIDERUSERID VARCHAR2(255) not null,
RANK           INTEGER not null,
DISPLAYNAME    VARCHAR2(255),
PROFILEURL     VARCHAR2(512),
IMAGEURL       VARCHAR2(512),
ACCESSTOKEN    VARCHAR2(255) not null,
SECRET         VARCHAR2(255),
REFRESHTOKEN   VARCHAR2(255),
EXPIRETIME     NUMBER(19)
) ;

-- Create/Recreate primary, unique and foreign key constraints
alter table USERCONNECTION
add primary key (USERID, PROVIDERID, PROVIDERUSERID) ;

-- Create/Recreate indexes
create unique index USERCONNECTIONRANK on USERCONNECTION (USERID, PROVIDERID, RANK) ;

----------------------------------------- Create table
create table USER_ACCOUNTS
(
ID         VARCHAR2(255) not null,
EMAIL      VARCHAR2(100) not null,
USER_NAME      VARCHAR2(100) not null,
FIRST_NAME VARCHAR2(100) not null,
LAST_NAME  VARCHAR2(100) not null,
PASSWORD   VARCHAR2(255),
ROLE       VARCHAR2(20) not null,
ENABLED    VARCHAR2(1) default 'Y' not null
) ;
-- Create/Recreate primary, unique and foreign key constraints
alter table USER_ACCOUNTS
add primary key (ID) ;
alter table USER_ACCOUNTS
  add constraint User_Account_UK1 unique (EMAIL);
alter table USER_ACCOUNTS
  add constraint User_Account_UK2 unique (USER_NAME);
** MYSQL/SQL SERVER **
-- Create table
create table USERCONNECTION
(
USERID         VARCHAR(255) not null,
PROVIDERID     VARCHAR(255) not null,
PROVIDERUSERID VARCHAR(255) not null,
RANK           INTEGER not null,
DISPLAYNAME    VARCHAR(255),
PROFILEURL     VARCHAR(512),
IMAGEURL       VARCHAR(512),
ACCESSTOKEN    VARCHAR(255) not null,
SECRET         VARCHAR(255),
REFRESHTOKEN   VARCHAR(255),
EXPIRETIME     BIGINT
) ;

-- Create/Recreate primary, unique and foreign key constraints
alter table USERCONNECTION
add primary key (USERID, PROVIDERID, PROVIDERUSERID) ;

-- Create/Recreate indexes
create unique index USERCONNECTIONRANK on USERCONNECTION (USERID, PROVIDERID, RANK) ;

-----------------------------------------
-- Create table
create table USER_ACCOUNTS
(
ID         VARCHAR(255) not null,
EMAIL      VARCHAR(100) not null,
USER_NAME      VARCHAR(100) not null,
FIRST_NAME VARCHAR(100) not null,
LAST_NAME  VARCHAR(100) not null,
PASSWORD   VARCHAR(255),
ROLE       VARCHAR(20) not null,
ENABLED    VARCHAR(1) default 'Y' not null
) ;
-- Create/Recreate primary, unique and foreign key constraints
alter table USER_ACCOUNTS
add primary key (ID) ;
alter table USER_ACCOUNTS
 add constraint User_Account_UK1 unique (EMAIL);
alter table USER_ACCOUNTS
 add constraint User_Account_UK2 unique (USER_NAME);

USERCONNECTION & USER_ACCOUNTS

Wenn Sie eine Applikation Web Spring schon haben und ins System durch die in einer Tabelle gespeicherten Konten zugreifen, z.B   USER_ACCOUNTS. (Achtung: die Struktur von Ihrer Tabelle Users kann mit der Struktur dieser Tabelle unterscheiden).
Sie können die Anmeldungsfunktion ins Ihrer Webseite durch das soziale Netwerk integrieren. Sie sollen eine Tabelle USERCONNECTION erstellen. Beachten Sie: Die Struktur von der Tabelle wird durch Spring Social Security API gebietet, Deshalb wird die Funktion von   insert, update der Daten in dieser Tabelle durch API unterstützt. Allerdings können Sie ihre Struktur anpassen
Beachten Sie: Das Funktion von insert, update in die Tabelle  USERCONNECTION werden durch die Klasse JdbcUsersConnectionRepository von  Spring Social Security API durchgeführt.
Die Daten des Beispiel

2- Das Anmeldungsmodell

Falls der Benutzer durch das Sozielle Netwerk anmelden, fordert Ihre Applikation den Benutzer, die Zugang der grundlegenden Informationen (der Name, das Email ...) zu genehmigen. Wenn der Benutzer nicht einverstanden ist, leitet das Programm nach die Seite /signin weiter damit der Benutzer normal anmeldet
Falls der Benutzer erlaubt, dass die Applikation seine Basisinformation zugreifen kann, gibt es 2 Modelle zum Arbeiten wie folgend:

Das Modell 1 : die Registrierungsseite anzeigen nach der Anmeldung in dem soziellen Netwerk

Nachdem der Benutzer durch das sozielle Netwerk anmeldet, haben Sie UserProfile. Das ist ein Speicherungsobjekt der Basisinformation des Benutzer und des soziellen Netwerk. Sie können userID in der Tabelle USERCONNECTION finden, die den Informationen  UserProfile entsprechen, und das Rekord vom USER_ACCOUNTS entsprechende mit Us erID finden. Ohne das entsprechendes Rekord in der Tabelle USER_ACCOUNTS leitet es nach der Registrierungsseite.

NAchdem der Benutzer registriert, wird ein Rekord USER_ACCOUNTS erstellt, gleichzeitig ein Rekord USERCONNECTION auch erstellt. Und automatisch in die Website anmelden

Das Modell 2: das Konto automatisch erstellen nach der Anmeldung ins sozielle Netwerk

Das Modell ist ähnlich wie das Modell 1 oben. Wenn ein UserProfile entsprechenden Rekord USERCONNECTIONS nicht gefunden ist, wird ein Rekord User_Accounts erstellt, gleichzeitig ein Rekord USERCONNECTION erstellt.

3- Oauth2 registrieren

Wenn Sie in Goolge anmelden möchten, brauchen Sie Client ID und Password und melden Sie Redirect URL an, nach dem Ihre Applikation weiterleiten kann wenn der Benutzer Google erfolgreich anmelden. Mehr detailiert bei.. sehen:
So gleich wie  Facebook sollen Sie  Facebook Developer Application und  App ID erstellen, sowie die   Redirect URL anmelden, nach dem Ihre Applikation weiterleiten kann wenn der Benutzer Facebook erfolgreich zugreifen. Mehr detailiert bei... sehen

MySocialUserDetails ist die Klasse der Durchführung der Interface SocialUserDetails, beachten Sie:  SocialUserDetails ist eine aus  UserDetails verlängerte Interface. Das Login durch das sozielle Netwerk mit der Benutzung von Spring MVC Social API basiert auf Spring Security API.

MyUserDetailsService ist die Dienstleistung, die durch Spring Security API zur Informationschaffung des Benutzer aus Database benutzt wird.

SocialUserDetailsService ist die Dienstleistung, die durch Spring Social Security API benutzt wird, um die Benutzersinformation aus Database zu laden 
Spring Social Security API ist ein API , das auf  Spring Security API basiert wird, es ersetzt  Spring Security API nicht.

7- Die Klasse zur Kontosregistrierung  (SignUp)

Wie oben gemeint, wenn die Information des Benutzer nach dem Login durch das sozielle Netwerk in die Database der Applikation existiert nicht, werden sie automatisch erstellt oder leitet sie nach einer Seite weiter, damit der Benutzer die Information des Konto eingeben kann 
Falls Sie die Rekord   USER_ACCOUNTS & USERCONNECTION automatisch erstellen möchsten, sollen Sie die Klasse zur Durchführung der Interface   ConnectionSignUp schreiben

    // After login Social.
    // This method is called to create a USER_ACCOUNTS record
    // if it does not exists.
    @Override

10- Die Applikation durchführen

Beachten Sie: Die Applikation zu prüfen, können Sie die Daten User im Database löschen und Cache des Browser löschen
Delete from User_Accounts;
Delete From Userconnection;

Das Konto automatisch erstellen

Falls Sie möchten, der Benutzer durch das sozielle Netwerk anmelden und die Rekorde USERCONNECTION & USER_ACCOUNTS automatisch erstellt werden, sollen Sie die Klasse SocialConfig erstellen:
** SocialConfig.java **
@Configuration
@EnableSocial
// Load to Environment.
@PropertySource("classpath:social-cfg.properties")
public class SocialConfig implements SocialConfigurer {
  
    // .....
    private boolean autoSignUp = true;

   .......
}

Die Registrierungsseite anzeigen​​​​​​​

Falls der Benutzer durch das sozielle Netwerk anmeldet und keine entsprechenden Rekorden USERCONNECTION hat, leitet die Applikation nach der Registrierungsseite. Sie sollen die Klasse  SocialConfig verändern:
** SocialConfig.java **
@Configuration
@EnableSocial
// Load to Environment.
@PropertySource("classpath:social-cfg.properties")
public class SocialConfig implements SocialConfigurer {
  
    // .....
    private boolean autoSignUp = false;

   .......
}
