springboot+springsecurity+redis实现登录验证session共享我们知道 springsecurity 是spring 家族中⼀个安全登录框架 简介的话 ⼤家可以去百度搜索⼀下 我这就不⼀⼀介绍了  主要是懒
废话不多说 直接上代码 需要的pom ⽂件 我这⾥⽤的是redis  +mybatis plus +mysql +springboot +springsecurity+spring-seesion

1创建⼀个springboot项⽬ 引⼊上述pom  ⽂件
我在这⾥是根据不同的环境 ⽤不同 的配置⽂件 来配置⽂件
#spring.profiles.active=dev
server.port=9998
spring.datasource.url = jdbc:mysql://127.0.0.1/test?serverTimezone=UTC&useSSL=false&allowPublicKeyRetrieval=true
serverTimezone=UTC&useSSL=false&allowPublicKeyRetrieval=true
spring.datasource.username =root
spring.datasource.password =root
spring.datasource.driverClassName = sql.cj.jdbc.Driver
# MyBatis-plus 配置
mybatis-plus.mapper-locations=classpath:/mybatis/*l
mybatis-plus.global-config.id-type=2
mybatis-plus.global-config.field-strategy=2
mybatis-plus.global-config.db-column-underline=true
fresh-mapper=true
mybatis-plus.global-config.logic-delete-value=0
mybatis-plus.global-config.logic-not-delete-value=1
#dis.password=
## 连接池中的最⼤空闲连接
## 连接池最⼤阻塞等待时间（使⽤负值表⽰没有限制）
我们需要在application 启动处加⼊这个注解  这个注解的主要作⽤就是讲sessio 存到redis 中 从⽽实现seeion 共享 注解⾥⾯的参数 是值60秒后失效 也就是说你需要重新登录 ⼀般都设置1800 秒 就是30分钟 这⾥我是⽤来做测试的
下⾯是springsecurity 相关代码 ⾸先 创建⼀个
WebSecurityConfig ⽂件
@Configuration
public class WebSecurityConfig  extends WebSecurityConfigurerAdapter{
@Bean
public SessionRegistry getSessionRegistry(){
SessionRegistry sessionRegistry=new SessionRegistryImpl();
return sessionRegistry;
}
