基于SpringBoot2.0默认使用Redis连接池的配置操作

 redis:
  cluster:
   nodes: ${redis.host.cluster}
  password: ${redis.password}
  lettuce:
   shutdown-timeout: 100 # 关闭超时时间
   pool:
    max-active: 8 # 连接池最大连接数（使用负值表示没有限制）
    max-idle: 8 # 连接池中的最大空闲连接
    max-wait: 30 # 连接池最大阻塞等待时间（使用负值表示没有限制）
    min-idle: 0 # 连接池中的最小空闲连接
