【静态内部类】使用案例

一、使用静态内部类，声明框架代码，不允许外部调用者使用的方式

@Configuration
@ConditionalOnClass({ThriftServerPublisher.class})
@ConditionalOnProperty(
    prefix = "thrift",
    name = {"enabled"},
    havingValue = "true",
    matchIfMissing = true
)
public class ThriftServerPublisherAutoConfiguration {
    private static final Logger log = LoggerFactory.getLogger(ThriftServerPublisherAutoConfiguration.class);

    public ThriftServerPublisherAutoConfiguration() {
    }

    @Bean
    public static ThriftServerPublisherAutoConfiguration.ThriftServerPublisherBeanDefinitionRegistryPostProcessor thriftServerPublisherBeanDefinitionRegistryPostProcessor() {
        return new ThriftServerPublisherAutoConfiguration.ThriftServerPublisherBeanDefinitionRegistryPostProcessor();
    }

    static class ThriftServerPublisherBeanDefinitionRegistryPostProcessor implements BeanDefinitionRegistryPostProcessor {
        ThriftServerPublisherBeanDefinitionRegistryPostProcessor() {
        }

        public void postProcessBeanDefinitionRegistry(BeanDefinitionRegistry beanDefinitionRegistry) throws BeansException {
            //填充业务逻辑代码，向spring容器中注入业务bean
    }
}
