2.3、RedieHelper帮助类核心
/***
* Title:"数据采集" 项目
* 主题:Redis帮助类
* Description:
* 功能:
* 1、设置连接字符串、选择数据库、获取到连接状态
* 2、给键添加前缀
* 3、String操作
* 【同步(①保存单个键值对)(②根据键获取到对应的值)(③同时保存多个键值对)(④存储一个对象)(⑤获取一个对象)】
*
* 【异步(①保存单个键值对)(②根据键获取到对应的值)(③同时保存多个键值对)(④存储一个对象)(⑤获取一个对象)】
* 4、Hash操作
* 【同步(①判断单个键值对是否存在Hash中)(②从Hash中移除单个键值对)(③从Hash中同时移除单个键对应的多个字段列表)(④在Hash中指定值)
* (⑤在Hash中同时添加单个键指定的多个字段列表)(⑥在Hash中获取单个键、字段对应的值)(⑦在Hash中同时获取单个键对应的指定字段)
* (⑧在Hash中获取单个键对应的所有字段)(⑨在Hash中获取单个键对应的所有值)(⑩在Hash中给单个键的单个字段添加一个对象值)(⑩①在Hash中获取单个键单个字段对应的对象值)】
*
* 【异步(①判断单个键值对是否存在Hash中)(②从Hash中移除单个键值对)(③从Hash中同时移除单个键对应的多个字段列表)(④在Hash中指定值)
* (⑤在Hash中同时添加单个键指定的多个字段列表)(⑥在Hash中获取单个键、字段对应的值)(⑦在Hash中同时获取单个键对应的指定字段)
* (⑧在Hash中获取单个键对应的所有字段)(⑨在Hash中获取单个键对应的所有值)(⑩在Hash中给单个键的单个字段添加一个对象值)(⑩①在Hash中获取单个键单个字段对应的对象值)】
* 5、List操作
* 【同步(①移除并返回列表中该键对应的第一个元素)(②移除并返回列表中该键对应的最后一个元素)(③移除列表中指定键与该值相同的元素)
* (④在列表尾部插入值。如果键不存在,先创建再插入值)(⑤在列表头部插入值。如果键不存在,先创建再插入值)(⑥返回列表上该键的长度,如果不存在,返回 0)
* (⑦返回在该列表上键所对应的起止点元素)(⑧移除并返回存储在该键列表的第一个元素对象)(⑨移除并返回存储在该键列表的最后一个元素对象)
* (⑩在列表尾部插入值。如果键不存在,先创建再插入值)(⑩①在列表头部插入值。如果键不存在,先创建再插入值)】
*
* 【异步(①移除并返回列表中该键对应的第一个元素)(②移除并返回列表中该键对应的最后一个元素)(③移除列表中指定键与该值相同的元素)

* 6、SortedSet操作
* 【同步(① SortedSet 新增)(②在有序集合中返回指定范围的元素,默认情况下从低到高)(③返回有序集合的元素个数)(④返回有序集合的元素个数)
* (⑤SortedSet 新增)(⑥增量的得分排序的集合中的成员存储键值键按增量)】
*
* 【异步(① SortedSet 新增)(②在有序集合中返回指定范围的元素,默认情况下从低到高)(③返回有序集合的元素个数)(④返回有序集合的元素个数)
* (⑤SortedSet 新增)(⑥增量的得分排序的集合中的成员存储键值键按增量)】
* 7、Key操作
* 【同步(①删除指定Key)(②删除指定Key列表)(③检查Key是否存在)(④重命名Key)(⑤设置Key的时间)】
*
* 【异步(①删除指定Key)(②删除指定Key列表)(③检查Key是否存在)(④重命名Key)(⑤设置Key的时间)】
* 8、发布订阅
* 【同步(①订阅)(②发布)】
