Spring Boot报错：No session repository could be auto-configured, check your configuration的解决方法

2019年07月22日  | 移动技术网IT编程  | 我要评论

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

 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：
