鉴权完成后如何拿到SpringSocial的用户信息

 package cn.coreqi.social.config;

 import org.springframework.beans.factory.annotation.Autowired;

 import org.springframework.context.annotation.Bean;

 import org.springframework.context.annotation.Configuration;

 import org.springframework.security.crypto.encrypt.Encryptors;

 import org.springframework.social.connect.jdbc.JdbcUsersConnectionRepository;

 import org.springframework.social.connect.web.ProviderSignInUtils;

 import org.springframework.social.security.SpringSocialConfigurer;

 import javax.sql.DataSource;

 @Configuration

 @EnableSocial

 public class SocialConfig extends SocialConfigurerAdapter {

     @Autowired

     private DataSource dataSource;

     /**

      *

      * @param connectionFactoryLocator  作用是去根据条件去查找应该用那个connectionFactory，因为系统中可能有很多的connectionFactory。

      * @return

      */

     @Override

     public UsersConnectionRepository getUsersConnectionRepository(ConnectionFactoryLocator connectionFactoryLocator) {

         //第三个参数的作用是把插入到数据库的数据进行加解密

         JdbcUsersConnectionRepository jdbcUsersConnectionRepository = new JdbcUsersConnectionRepository(dataSource,connectionFactoryLocator, Encryptors.noOpText());

         //jdbcUsersConnectionRepository.setTablePrefix(); //设置数据表的前缀

         return jdbcUsersConnectionRepository;

     }

     /**

      * 声明后还需要加在SpringSecurity过滤器链上

      * @return

      */

     @Bean

     public SpringSocialConfigurer coreqiSocialSecurityConfig(){

         CoreqiSpringSocialConfig config = new CoreqiSpringSocialConfig();

         config.signupUrl("/registry");  //当从业务系统中无法找到OAuth快捷登陆的用户，那么将用户引导到注册页面中

         return config;

     }

     //1.注册过程中如何拿到SpringSocial信息

     //2.注册完成后如何把业务系统的用户ID传给SpringSocial

     @Bean

     public ProviderSignInUtils providerSignInUtils(ConnectionFactoryLocator connectionFactoryLocator){

         return new ProviderSignInUtils(connectionFactoryLocator,getUsersConnectionRepository(connectionFactoryLocator));

     }

 }
