本文整理了Java中redis.clients.jedis.Jedis.hget()方法的一些代码示例，展示了Jedis.hget()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.hget()方法的具体详情如下：
包路径：redis.clients.jedis.Jedis
类名称：Jedis
方法名：hget

Jedis.hget介绍

[英]If key holds a hash, retrieve the value associated to the specified field.

If the field is not found or the key does not exist, a special 'nil' value is returned.

Time complexity: O(1)
[中]如果键包含散列，则检索与指定字段关联的值。
如果未找到字段或键不存在，则返回一个特殊的“nil”值。
时间复杂度：O（1）
