springboot项目启动报错找不到ConfigurationPropertiesBean

我这里大概pom是引入了spring-cloud-starter-oauth2之后就开始报这个错。。

解决办法：在其他网页里看错误原因似乎是

springboot的版本和springcloud的版本不匹配导致。

springboot版本用2.2.5.RELEASE  springcloud版本用Hoxton.SR3。

嗯。。就这还有一堆人在底下追问。。只需要在自己pom文件的标签里面的给改的新一点就行了，其他人回答说是2.2.5RELEASE，但是我这里只能用到2.2.4，但是错误依然解决了。只不过又报错新的了。。。。

No session repository could be auto-configured, check your configuration (session store type is 'redis')。

Session那边又出问题了，后来在启动类上面加了个@EnableRedisHttpSession 就好了。
