转 Spring Boot之No session repository could be auto-configured, check your configuration问题解决

1.  环境介绍

JDK 1.8  Spring-Boot 1.5.1.RELEASE, STS IDE

2.  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：

  1. <dependency>
  2. <groupId>org.springframework.session</groupId>
  3. <artifactId>spring-session</artifactId>
  4. lt;/dependency>

在启动过程中，出现了如下错误信息：

  1. 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。

3.  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：

  1. # default-store in spring session. it will be set in redis only outside.
  2. 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：
