### 集成redis后对象模型序列化异常
假设执行如下代码:
``` java
@Data
public class User implements Serializable {
private Long userId;
private String username;
private String password;
}
User user = new User();
user.setUserId(10000L);
user.setUsername("oneName");
user.setPassword("onePass");
StpUtil.getSession().set("userObjKey", user); // 这里报错
```
报错信息如下:
```
SerializationException: Could not read JSON:
Cannot deserialize value of type `java.lang.Long` from Array value (token `JsonToken.START_ARRAY`)
```
springboot 集成 satoken redis 后, 一旦 springboot 切换版本就有可能出现此问题
原因是redis里面有之前的 satoken 会话数据, 清空 Redis 即可
