SpringBoot报错：
本⽂主要跟⼤家分享了关于Spring Boot报错：No session repository could be auto-configured, check your configuration的解决⽅法，下⾯话不多说，来⼀起看看详细的介绍：
⼀、环境介绍
JDK 1.8  spring-Boot 1.5.1.RELEASE, STS IDE
⼆、问题的提出
创建了⼀个⾮常简约的Spring Boot Web Application，其中使⽤了Spring-Session，具体的maven依赖如下：
<dependency>
<groupId>org.springframework.session</groupId>
<artifactId>spring-session</artifactId>
lt;/dependency>
在启动过程中，出现了如下错误信息：
Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.

异常栈很长，关键的错误信息是：No session repository could be auto-configured, check your configuration (session store type is 'null') ，这个信息对于我们进⾏问题分析提供了⾮常⼤的指引，我们将重点放在session
store type的功能分析上。
三、问题的解决与分析
session数据错误是什么意思在⽹上搜索之后，我们发现session store type使⽤来存放session的存储⽅式，⽬前Spring boot中只⽀持Redis⽅式。由于本应⽤暂⽆需将session放⼊redis的需求，故这⾥就可以将session store type设置
为none.
这⾥我们将此配置信息放⼊application.properites之中：
# default-store in spring session. it will be set in redis only outside.
spring.session.store-type=none
重新启动应⽤，错误信息消失，我们可以看到了启动正常的信息了：
