springboot（spring也一样的）整个redis 的时候报如下错误：

错误原因：连接超时时间设置的过于短暂（我这边设置成了0），修改为5000左右即可

# REDIS (RedisProperties)
    # Redis数据库索引（默认为0）
    spring.redis.database=0
    # Redis服务器地址
    spring.redis.host=192.168.30.103
    # Redis服务器连接端口
    spring.redis.port=6379
    # Redis服务器连接密码（默认为空）
    spring.redis.password=
    # 连接池最大连接数（使用负值表示没有限制）
    spring.redis.jedis.pool.max-active=8
    # 连接池最大阻塞等待时间（使用负值表示没有限制）
    spring.redis.jedis.pool.max-wait=-1

    # 连接池中的最小空闲连接
    spring.redis.jedis.pool.min-idle=0
    # 连接超时时间（毫秒）
    spring.redis.timeout=5000
