@Bean
RedisCacheManagerBuilderCustomizer redisCacheManagerBuilderCustomizer() {
    return builder -> builder.withCacheConfiguration(
    		// @Cacheable 注解使用的cacheNames参数值
            CACHE_NAME_1,
            builder
		            // 获取全局配置
                    .cacheDefaults()
                    // 在全局配置基础上添加超时时间配置
                    .entryTtl(Duration.ofSeconds(60))
    ).withCacheConfiguration(
            CACHE_NAME_2,
            builder
                    .cacheDefaults()
                    .entryTtl(Duration.ofSeconds(60))
