SocialAutoConfigurerAdapter在哪个包下面：

 
spring-boot-autoconfigure2.x中版本找不到了只能重写

public abstract class SocialAutoConfigurerAdapter extends SocialConfigurerAdapter {
    public SocialAutoConfigurerAdapter() {
    }
    public void addConnectionFactories(ConnectionFactoryConfigurer configurer, Environment environment) {
        configurer.addConnectionFactory(this.createConnectionFactory());
    }
    protected abstract ConnectionFactory<?> createConnectionFactory();
}
