分析：根据信息提示可以看出项目中使用到了 Redis 进行session管理，因此需要引入Redis库。

解决办法：引入spring-boot-starter-data-redis库

修改前：

<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-data-redis</artifactId>
</dependency>

修改后：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-data-redis</artifactId>
</dependency>
