一、@EnableConfigurationProperties注解的作用
@Configuration @ConditionalOnClass(RedisOperations.class) @EnableConfigurationProperties(RedisProperties.class) @Import({ LettuceConnectionConfiguration.class, JedisConnectionConfiguration.class }) public class RedisAutoConfiguration { ... }
RedisProperties类上没有加@Component等注解，也可以注册到Spring容器中
@ConfigurationProperties(prefix = "spring.redis") public class RedisProperties { ... }
