Session一致性问题

• Nginx的 IP_Hash 策略

同⼀个客户端IP的请求都会被路由到同⼀个⽬标服务器，也叫做会话粘滞

在nginx的  niginx.conf 中 添加ip_hash

  

• Spring Session+ Redis的Session共享应⽤

以SpringBoot中部署为例

1. 编入依赖包

 
    org.springframework.boot
     spring-boot-starter-data-redis


      org.springframework.session
      spring-session-data-redis

   2. application.properties中引入配置

spring.redis.host=localhost
spring.redis.database=0
spring.redis.port=6379
spring.redis.password=
spring.redis.connect-timeout=5000

3. 引入注解 

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;

@SpringBootApplication
@EnableCaching
@EnableRedisHttpSession
public class LoginprojectApplication {

    public static void main(String[] args) {
        SpringApplication.run(LoginprojectApplication.class, args);
    }
    
}

4. nginx中转发配置
