spring boot 启动报错：Reason: Canonical names should be kebab-case ('-' separated), lowercase

spring boot 1.x 切换 2.x 以后启动报如下错误：

***************************
APPLICATION FAILED TO START
***************************Description:Configuration property name 'sysConf' is not valid:Invalid characters: 'C'Bean: sysConfReason: Canonical names should be kebab-case ('-' separated), lowercase alpha-numeric characters and must start with a letterAction:Modify 'sysConf' so that it conforms to the canonical names requirements.

从报错信息可以看出，spring boot 2.x 中对配置文件中名称的命名规范进行了强制约束，需要使用kebab格式，不能使用java中的驼峰式写法了，分隔符使用 ’-‘ 来分隔

#系统配置
sys-conf:session-alive-time: 1800

修改以后启动成功
