centos7、 jdk1.8、nginx、redis、springboot 1.5.8.RELEASE
添加spring session和redis依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.session</groupId>
<artifactId>spring-session</artifactId>
</dependency>
application.properties配置
# session 存入 redis
spring.session.store-type=redis
# redis config
spring.redis.database=0
spring.redis.host=127.0.0.1
spring.redis.port=6379
spring.redis.password=123456
spring.redis.pool.max-active=8
spring.redis.pool.max-wait=20000
spring.redis.pool.max-idle=8
spring.redis.pool.min-idle=0
spring.redis.timeout=0
此处redis密码设置为123456
测试代码
@RequestMapping("user")
@RestController
public class UserController {
@GetMapping("getSessionId")
public String getSessionId(HttpServletRequest request) {
String sessionId = request.getSession().getId();
System.out.println(sessionId);
return sessionId;
}
}

?
nginx.conf配置
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
upstream springboot-session-redis {
server 127.0.0.1:8081;
server 127.0.0.1:8082;
server 127.0.0.1:8083;
}
server {
listen 80;
server_name localhost;
location / {
proxy_pass http://springboot-session-redis;
proxy_set_header Host $host;
# 此配置使得服务端可以获取客户端真实ip
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_redirect off;
}
}
}
启动redis
systemctl start redis
启动三个应用服务
使用maven打包成jar包后 ,在后台运行三个服务,端口分别为8081、8082、8083,日志分别输出到nohup.out、nohup2.out、nohup3.out
nohup java -jar springboot-session-redis-0.0.1-SNAPSHOT.jar --server.port=8081 > nohup.out &
nohup java -jar springboot-session-redis-0.0.1-SNAPSHOT.jar --server.port=8082 > nohup2.out &
nohup java -jar springboot-session-redis-0.0.1-SNAPSHOT.jar --server.port=8083 > nohup3.out &
启动nginx
访问http://ip/user/getSessionId
页面显示sessionId的值
? nginx默认负载均衡策略是采用轮询,此处启动了三个服务,所以访问三次该网址,查看三个服务的日志,会发现每个服务处理了一次请求。
如下图:
nohup.out
nohup2.out
nohup3.out
从上图可知三次输出的sessionId的值也是一样的,所以实现了session共享,也通过nginx实现了负载均衡。
查看redis存储的值
可以看到生成了三个与spring session相关的key
springboot+spring session+redis+nginx实现session共享和负载均衡
