  使用Spring Boot Redis缓存，项目启动时报错

  The following candidates were found but could not be injected:
  	- Bean method 'redisConnectionFactory' in 'JedisConnectionConfiguration' not loaded because @ConditionalOnClass did not find required classes 'org.apachemons.pool2.impl.GenericObjectPool', 'redis.clients.jedis.Jedis'
  	- Bean method 'redisConnectionFactory' in 'LettuceConnectionConfiguration' not loaded because @ConditionalOnClass did not find required class 'io.lettuce.core.RedisClient'
  

  控制台提示：

  其实就是导入依赖不全，检查pom.xml：
