详解spring boot starter redis配置文件

# Redis服务器地址
spring.redis.host=192.168.0.58
# Redis服务器连接端口
spring.redis.port=6379 
# Redis服务器连接密码（默认为空，如果redis服务端配置文件开启了requirepass 密码，此处就应该填写相应的配置密码）
spring.redis.password= 
# 连接超时时间（毫秒）
spring.redis.timeout=0

# 连接池最大连接数（使用负值表示没有限制，对应maxTotal）
spring.redis.pool.max-active=8
# 连接池中的最大空闲连接
spring.redis.pool.max-idle=8
# 连接池中的最小空闲连接
spring.redis.pool.min-idle=0
