nested exception is io.lettuce.core.RedisCommandTimeoutException

完整报错：org.springframework.dao.QueryTimeoutException: Redis command timed out; nested exception is io.lettuce.core.RedisCommandTimeoutException: Command timed out after 5 second(s)

我服务上线老是连接超时，之前以为是网不好，但发现超时时间设置为5秒也还是每次都超时，然后查阅资料后发现需要把连接池从lettuce改为jedis：

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>io.lettuce</groupId>
                    <artifactId>lettuce-core</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
        </dependency>
