Spring Boot報錯：No session repository could be auto-configured, check your configuration的解決方法，
一、環境介紹
JDK 1.8 spring-Boot 1.5.1.RELEASE, STS IDE
二、 問題的提出
創建了一個非常簡約的Spring Boot Web Application，其中使用了Spring-Session，具體的maven依賴如下：
<dependency> <groupId>org.springframework.session</groupId> <artifactId>spring-session</artifactId> lt;/dependency>
在啟動過程中，出現了如下錯誤信息：
Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled. 2017-02-23 17:48:10.710 ERROR 29484 --- [ restartedMain] o.s.boot.SpringApplication : Application startup failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.session.SessionAutoConfiguration$SessionRepositoryValidator': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: No session repository could be auto-configured, check your configuration (session store type is 'null') at org.springframework.beans.factory.annotation.InitDestroyAnnotationBeanPostProcessor.postProcessBeforeInitialization(InitDestroyAnnotationBeanPostProcessor.java:137) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyBeanPostProcessorsBeforeInitialization(AbstractAutowireCapableBeanFactory.java:409) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1620) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:555) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:483) at org.springframework.beans.factory.support.AbstractBeanFactory$1.getObject(AbstractBeanFactory.java:306) at org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:230) at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:302) at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:197) at org.springframework.beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons(DefaultListableBeanFactory.java:761) at org.springframework.context.support.AbstractApplicationContext.finishBeanFactoryInitialization(AbstractApplicationContext.java:866) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:542) at org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.refresh(EmbeddedWebApplicationContext.java:122) at org.springframework.boot.SpringApplication.refresh(SpringApplication.java:737) at org.springframework.boot.SpringApplication.refreshContext(SpringApplication.java:370) at org.springframework.boot.SpringApplication.run(SpringApplication.java:314) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1162) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1151) at org.rosebird.data.stock.StockdataApplication.main(StockdataApplication.java:10) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at org.springframework.boot.devtools.restart.RestartLauncher.run(RestartLauncher.java:49) Caused by: java.lang.IllegalArgumentException: No session repository could be auto-configured, check your configuration (session store type is 'null') at org.springframework.util.Assert.notNull(Assert.java:115) at org.springframework.boot.autoconfigure.session.SessionAutoConfiguration$SessionRepositoryValidator.checkSessionRepository(SessionAutoConfiguration.java:100) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at org.springframework.beans.factory.annotation.InitDestroyAnnotationBeanPostProcessor$LifecycleElement.invoke(InitDestroyAnnotationBeanPostProcessor.java:366) at org.springframework.beans.factory.annotation.InitDestroyAnnotationBeanPostProcessor$LifecycleMetadata.invokeInitMethods(InitDestroyAnnotationBeanPostProcessor.java:311) at org.springframework.beans.factory.annotation.InitDestroyAnnotationBeanPostProcessor.postProcessBeforeInitialization(InitDestroyAnnotationBeanPostProcessor.java:134) ... 23 common frames omitted
異常棧很長，關鍵的錯誤信息是：No session repository could be auto-configured, check your configuration (session store type is 'null') ，這個信息對于我們進行問題分析提供了非常大的指引， 我們將重點放在session store type的功能分析上。
三、問題的解決與分析
在網上搜索之后，我們發現session store type使用來存放session的存儲方式，目前Spring boot中只支持redis方式。 由于本應用暫無需將session放入redis的需求，故這里就可以將session store type設置為none.
這里我們將此配置信息放入application.properites之中：
# default-store in spring session. it will be set in redis only outside. spring.session.store-type=none
重新啟動應用，錯誤信息消失， 我們可以看到了啟動正常的信息了：
