/**
* 自定义 RedisCacheManager支持在 cacheName 中通过 '#' 指定 TTL过期时间
* @Author CoderKK
* @Date 2025-08-15 13:01:01
* <p>
* 支持格式{@code cacheName#ttl}其中 ttl 支持 Spring Duration 格式
* 特殊值{@code -1} 表示永久缓存永不过期
* </p>
*
* <h3>使用示例</h3>
* <pre>
* // 10 秒后过期
* &#64;Cacheable(value = "user#10s", key = "#id")
* // 2 小时后过期
* &#64;Cacheable(value = "report#2h", key = "#date")
* // 30 分钟后过期
* &#64;Cacheable(value = "session#30m", key = "#token")
* // 永不过期永久缓存适用于极少变化的配置数据
* &#64;Cacheable(value = "appConfig#-1", key = "'globalSettings'")
* // TTL使用全局默认过期时间 7
* &#64;Cacheable(value = "product", key = "#productId")
* </pre>
*
* <h3>生成的 Redis Key 格式</h3>
* <pre>
* cache:cacheName:key
* 例如cache:user:123
* cache:appConfig:globalSettings
* </pre>
*
* <h3>支持的 TTL 单位</h3>
* <ul>
* <li>{@code ms} / {@code millis} / {@code milliseconds} - 毫秒</li>
* <li>{@code s} / {@code secs} / {@code seconds} - </li>
* <li>{@code m} / {@code mins} / {@code minutes} - 分钟</li>
* <li>{@code h} / {@code hrs} / {@code hours} - 小时</li>
* <li>{@code d} / {@code days} - </li>
* </ul>
*
* <h3>注意事项</h3>
* <ul>
* <li>不写单位默认为毫秒</li>
* <li>永久缓存#-1不会自动过期请配合 &#64;CacheEvict 手动清理</li>
* <li>避免对频繁更新的数据使用永久缓存防止数据陈旧</li>
* <li>cacheName 中的 '#' 只解析第一个后续字符将作为 TTL 处理</li>
* </ul>
