修改spring中lettuce的配置

spring:
  redis:
    host: localhost                             # 地址
    port: 6379                                  # 端口号
    database: 0                                 # 数据库
    timeout: 60000                              # 连接超时时间，单位为毫秒，60秒
    lettuce:
      pool:
        max-active: 100                         # 最大连接数，连接池中能够分配的最大连接数。如果设置为 -1，则表示无限制。默认8
        max-idle: 50                            # 最大空闲连接数，连接池中保持空闲的最大连接数。默认8
        min-idle: 20                            # 最小空闲连接数，连接池中保持空闲的最小连接数。默认0
        max-wait: -1ms                          # 最大等待时间，单位为毫秒。当连接池没有可用连接时，客户端调用获取连接的最大等待时间。如果设置为 -1，则表示无限制。默认-1
        time-between-eviction-runs: 60000ms     # 空闲连接驱逐检查的时间间隔，单位为毫秒。当设置为正值时，表示每隔多少毫秒进行一次空闲连接的检查。1分钟
      shutdown-timeout: 1000ms                  # 关闭超时时间，单位为毫秒,默认100毫秒
