#多层配置
spring:
redis:
database: 0
host: localhost
port: 6379
timeout: 0
pool:
max:
active: 8
wait: -1
idle: 8
min:
idle: 0
日志打印如下所示:
============= redisConnect ================
RedisConfiguration [host=localhost, port=6379, timeout=0, database=0, poolMaxWait=-1, poolMaxIdle=0, poolMinIdle=0, poolMaxActive=8]
参考:
1、spring boot加载复杂的yml文件获取不到值的问题
