* 尝试解决redisson长时间未使用导致掉线后再次连接超时

* 关注要不要排除 RedissonAutoConfiguration
*
* [org/springframework/boot/autoconfigure/cache/RedisCacheConfiguration.class]:
* Unsatisfied dependency expressed through method 'cacheManager' parameter 4;
* nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException:
* Error creating bean with name 'redissonConnectionFactory'
* defined in class path resource [org/redisson/spring/starter/RedissonAutoConfiguration.class]:
* Unsatisfied dependency expressed through method 'redissonConnectionFactory' parameter 0;
* nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException:
* No qualifying bean of type 'org.redisson.api.RedissonClient' available:
* expected single matching bean but found 2: redissonClient,singleRedisson

* 验证代码：

*
* String redisKey = "test#redissonInitByCode";
* stringRedisTemplate.opsForValue().set(redisKey, "redisson初始化Value");
* String redisValue = stringRedisTemplate.opsForValue().get(redisKey);
* log.info("代码初始化redisson成功，取值：{},如果要关闭代码初始化，配置：enable.redissonInitByCode=false",redisValue);
