前两天朋友问我，有没有使用过stackexchange.redis，问我要个封装类，由于之前都是使用servicestack.redis，由于servicestack.redis v4版本后是收费版的，所以现在也很有公司都在使用stackexchange.redis而抛弃servicestack.redis了。其实个人觉得，两个驱动都不错，只是由于servicestack.redis收费导致目前很多公司都是基于v3版本的使用，也有人说v3版本有很多bug，没有维护和升级，不过至少目前我是没发现bug。
不过servicestack.redis同stackexchange.redis比较，抛开收费的来说，确认比stackexchange.redis 更有优势。stackexchange.redis文档很少，更不要说国内的文档了，连github上面对应的介绍文档都是很片面，这点我真的觉得stackexchange.redis的作者至少要完善下文档，很多都是要看源码的例子才有。网上对stackexchange.redis的使用例子也比servicestack.redis少得多，不是说没人用，只是我查来查去，大部分都是基于string类型的数据进行使用的封装类，对于list，sortedset，hash的封装操作都很少，基本都是东写一点，西写一点，很难找到完整的。在参考了一些文章和源码后，这里提供一个自己封装的类，基本提供对于各种类型的使用封装，提供给大家学习使用，如果有哪里写的不好的，大家也可以互相交流。
connectionmultiplexer 封装
首先是 connectionmultiplexer 的封装，connectionmultiplexer对象是stackexchange.redis最中枢的对象。这个类的实例需要被整个应用程序域共享和重用的，所以不需要在每个操作中不停的创建该对象的实例，一般都是使用单例来创建和存放这个对象，这个在官网上也有说明。

其中customkey用来表示系统前缀，addsyscustomkey方法对每个key都进行前缀的添加处理，这里推荐大家在命名redis的key的时候最好的加上前缀，并且使用 ：来分割前缀 ,这里在使用可视化工具查看的时候就比较好区分，比如我的的前缀是 demo:test:（一般是 系统名：业务名：）,然后你查看的时候你会发现整齐，好区分了很多

这里说一下，stackexchange.redis 中对对象的存储是不自带序列化和反序列化的方法，所以在convertjson和convertobj里面我是使用了jsonconvert来操作，如果需要换成其他的序列化和序列化，直接修改这两个方面就好了，另外，stackexchange.redis 相对于servicestack.redis 来说提供了异步的方法，所以这里也同样封装了异步和同步的方法。

以上就是对stackexchange.redis基本操作的通用封装，提供给大家学习参考，如果有哪里写错的，也希望能一起交流。
问题：
stackexchange.redis没有提供redis分布式锁的操作么？servicestack.redis 提供了acquirelock 的方法来操作，stackexchange.redis 源码中只找到了locktake的方法，并没有找到其他的方法了，如果有人使用过，还希望能提供下。
最后，附上源码地址：demo
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持服务器之家。
