项目环境：springboot1.5.10+redis2.9.0
applicaton.properties配置如下
om.xml依赖如下
然后写一个RedisConfig类作为Redis常用属性封装来提供调用。如下
Spring Boot APP启动没有出现异常，输入地址localhost:8080/testRedis 页面报错了：Could not get a resource from the pool
打开eclipse控制台
问题已经很明显了，ERR Client sent AUTH,but no password is set 没有密码输入，Redis没有设置密码导致这个问题。
进入想对应Redis安装路径下 vi redis.conf查看 requirepass password这一行已经被注释，所以把#号去掉，重启Redis服务器
。1../redis.server redis.conf使redis.conf修改的配置生效
2. ps -ef | grep redis观察Redis启动是否成功
重新调用localhost:8080/testRedis
