java后台启动报redis错: ERR Client sent AUTH, but no password is set

Springboot项目启动后，报出了redis的错误：

原因及解决方案：

redis采用默认的linux服务器安装方式，默认是没有密码的，而我的springboot配置中，设置了密码

这里需要注意的是，如果没有密码，一定要将password的属性删除掉，密码为空也不行，我就是没有设置密码结果报了错，将password注释掉或者直接删除掉，再次启动，问题消失。

redis:
    host: 127.0.0.1  # redis服务器地址
    port: 6379 # redis服务器端口号
    # password: # redis密码

如果要使用密码，编辑服务器的redis.conf文件，找到 # requirepass foobared （大概在500行），去掉前面的注释，将默认密码foobared改为你自己的密码，保存，重启redis
