报错异常：java.lang.NoSuchMethodError: redis.clients.jedis.ScanResult.getStringCursor()Ljava/lang/String;

出现原因：  springboot 2.2.5中自带 jedis 版本为3.1.0 而 shiro-redis中使用的版本为2.9.0

引用的包：
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-dependencies</artifactId>
    <version>2.2.2</version>
    <type>pom</type>
    <scope>import</scope>
</dependency>

<dependency>
    <groupId>org.crazycake</groupId>
    <artifactId>shiro-redis</artifactId>
    <version>3.1.0</version>
</dependency>

解决方法：引用 jedis2.9.0 版本

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.9.0</version>
</dependency>

修改后比较完整的 pom
