spring-session-data-redis 学习记录

简介

Spring框架提供了组件支持多应用共享Session。我采用了spring-session-data-redis组件，将session缓存到redis中。下面简要说明制做Demo的过程和遇到的问题

Maven依赖

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-redis</artifactId>
	<version>1.4.7.RELEASE</version>
</dependency>
<dependency>
	<groupId>org.springframework.session</groupId>
	<artifactId>spring-session</artifactId>
</dependency>
<dependency>
	<groupId>org.springframework.session</groupId>
	<artifactId>spring-session-data-redis</artifactId>
</dependency>

配置application.yml

server: 
    session: 
        timeout: 1000
  
spring: 
    redis: 
        [ 忽略相关配置 ]        
    session: 
        store-type: redis
        redis: 
            namespace: abc

第一坑：redis config

- redis异常

ERR unknow command ' CONFIG '

- 解决方法

参考https://docs.spring.io/spring-session/docs/current/reference/html5/#api-redisoperationssessionrepository-sessiondestroyedevent
redis服务配置config set notify-keyspace-events Egx

第二坑： @EnableRedisHttpSession和application.yml配置冲突

框架选择@EnableRedisHttpSession的属性，并忽略application.yml中的配置；不推荐使用@EnableRedisHttpSession
