#===========Redis配置===========
# Redis数据库索引（默认为0）  
spring.redis.database=0
# Redis服务器地址  
spring.redis.host=127.0.0.1
# Redis服务器连接端口  
spring.redis.port=6379
# Redis服务器连接密码（默认为空）  
spring.redis.password=root
# 连接池最大连接数（使用负值表示没有限制）  
spring.redis.pool.max-active=200
# 连接池最大阻塞等待时间（使用负值表示没有限制）  
spring.redis.pool.max-wait=-1
# 连接池中的最大空闲连接 
spring.redis.pool.max-idle=10
# 连接池中的最小空闲连接  
spring.redis.pool.min-idle=0
# 连接超时时间（毫秒）
spring.redis.timeout=2000ms
spring.redis.jedis.pool.max-wait=-1ms
