本文整理了Java中io.jsonwebtoken.Claims类的一些代码示例，展示了Claims类的具体用法。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。Claims类的具体详情如下：
包路径：io.jsonwebtoken.Claims
类名称：Claims

Claims介绍

[英]A JWT Claims set.

This is ultimately a JSON map and any values can be added to it, but JWT standard names are provided as type-safe getters and setters for convenience.

Because this interface extends Map<String, Object>, if you would like to add your own properties, you simply use map methods, for example:

claims. 
Map#put(Object,Object)("someKey", "someValue");

Creation

It is easiest to create a Claims instance by calling one of the Jwts#claims() factory methods.
[中]一个JWTClaims set。
这最终是一个JSON映射，可以向其中添加任何值，但为了方便起见，JWT标准名称作为类型安全的getter和setter提供。
由于此接口扩展了Map<String，Object>，如果您想添加自己的属性，只需使用Map方法即可，例如：

claims. 
Map#put(Object,Object)("someKey", "someValue");

####创作
通过调用Jwts#Claims（）工厂方法之一，创建索赔实例最简单。
