源码分析关于SpringBoot2.x版本与1.5版本之间的问题

1.Social包在SpringBoot2.x移除问题

spring-boot-autoconfigure1.5x版本中支持facebook，领英和推特
官方文档：https://docs.spring.io/spring-boot/docs/1.5.18.RELEASE/api/

spring-boot-autoconfigure2.x中版本找不到了
官方文档：https://docs.spring.io/spring-boot/docs/2.1.1.RELEASE/api/

问题：遇到SocialAutoConfigurerAdapter，SocialProperties和SocialWebAutoConfigurerAdapter类不存在

解决方法：

不想引入1.5版本的springboot的话只能自己按照源码重写(复制粘贴)
官方Github也是这样写的：https://github.com/spring-projects/spring-social
SocialAutoConfigurerAdapter源码

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

SocialProperties源码

public abstract class SocialProperties {
    private String appId;
    private String appSecret;
    public SocialProperties() {
    }
    public String getAppId() {
        return this.appId;
    }
    public void setAppId(String appId) {
        this.appId = appId;
    }
    public String getAppSecret() {
        return this.appSecret;
    }
    public void setAppSecret(String appSecret) {
        this.appSecret = appSecret;
    }
}

SocialWebAutoConfiguration源码

@Configuration
@ConditionalOnClass({ConnectController.class, SocialConfigurerAdapter.class})
@ConditionalOnBean({ConnectionFactoryLocator.class, UsersConnectionRepository.class})
@AutoConfigureBefore({ThymeleafAutoConfiguration.class})
@AutoConfigureAfter({WebMvcAutoConfiguration.class})
public class SocialWebAutoConfiguration {
    public SocialWebAutoConfiguration() {
    }

    private static class SecurityContextUserIdSource implements UserIdSource {
        private SecurityContextUserIdSource() {
        }

        public String getUserId() {
            SecurityContext context = SecurityContextHolder.getContext();
            Authentication authentication = context.getAuthentication();
            Assert.state(authentication != null, "Unable to get a ConnectionRepository: no user signed in");
            return authentication.getName();
        }
    }

    @Configuration
    @ConditionalOnClass({SpringResourceResourceResolver.class})
    protected static class SpringSocialThymeleafConfig {
        protected SpringSocialThymeleafConfig() {
        }

        @Bean
        @ConditionalOnMissingBean
        public SpringSocialDialect springSocialDialect() {
            return new SpringSocialDialect();
        }
    }

    @Configuration
    @EnableSocial
    @ConditionalOnWebApplication
    @ConditionalOnClass({SecurityContextHolder.class})
    protected static class AuthenticationUserIdSourceConfig extends SocialConfigurerAdapter {
        protected AuthenticationUserIdSourceConfig() {
        }

        public UserIdSource getUserIdSource() {
            return new SocialWebAutoConfiguration.SecurityContextUserIdSource();
        }
    }

    @Configuration
    @EnableSocial
    @ConditionalOnWebApplication
    @ConditionalOnMissingClass({"org.springframework.security.core.context.SecurityContextHolder"})
    protected static class AnonymousUserIdSourceConfig extends SocialConfigurerAdapter {
        protected AnonymousUserIdSourceConfig() {
        }

        public UserIdSource getUserIdSource() {
            return new UserIdSource() {
                public String getUserId() {
                    return "anonymous";
                }
            };
        }
    }

    @Configuration
    @EnableSocial
