鉴权完成后如何拿到SpringSocial的用户信息

⒈

 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.config.annotation.EnableSocial;
 import org.springframework.social.config.annotation.SocialConfigurerAdapter;
 import org.springframework.social.connect.ConnectionFactoryLocator;
 import org.springframework.social.connect.UsersConnectionRepository;
 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));
     }
 }
