本文整理了Java中redis.clients.jedis.Jedis.msetnx()方法的一些代码示例，展示了Jedis.msetnx()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Jedis.msetnx()方法的具体详情如下：
包路径：redis.clients.jedis.Jedis
类名称：Jedis
方法名：msetnx

Jedis.msetnx介绍

[英]Set the the respective keys to the respective values. #mset(String...) will replace old values with new values, while MSETNX will not perform any operation at all even if just a single key already exists.

Because of this semantic MSETNX can be used in order to set different keys representing different fields of an unique logic object in a way that ensures that either all the fields or none at all are set.

Both MSET and MSETNX are atomic operations. This means that for instance if the keys A and B are modified, another client talking to Redis can either see the changes to both A and B at once, or no modification at all.
[中]将相应的键设置为相应的值#mset（字符串…）将用新值替换旧值，而MSETNX将根本不执行任何操作，即使只有一个键已经存在。
由于这种语义，可以使用MSETNX来设置表示唯一逻辑对象的不同字段的不同键，以确保设置所有字段或根本不设置任何字段。
MSET和MSETNX都是原子操作。这意味着，例如，如果密钥A和B被修改，与Redis对话的另一个客户端可以立即看到A和B的更改，或者根本不进行任何修改。
