苹果登录后台token校验分为2种方式：
1、jwt校验
2、授权码校验
我这里记录一下第一种方式
流程大致如下：
在这里插入图片描述
添加maven依赖：

<dependency>
    <groupId>io.jsonwebtoken</groupId>
    <artifactId>jjwt</artifactId>
    <version>0.9.1</version>
</dependency>
<dependency>
    <groupId>com.auth0</groupId>
    <artifactId>jwks-rsa</artifactId>
    <version>0.9.0</version>
</dependency>
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.60</version>
</dependency>
