Spring Cloud项目通过Redis实现Session共享

一、添加Redis相关依赖

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

二、项目添加Redis配置信息

1、需要使用Redis的模块添加Redis配置信息

#配置redis连接信息
spring.session.store-type=redis
spring.redis.host=192.168.211.128
spring.redis.port=6379
spring.redis.password=

 2、给网关添加Redis配置信息

#配置redis连接信息
spring.redis.host=192.168.211.128
spring.redis.port=6379
spring.redis.password=
#配置网关相关参数
zuul.sensitive-headers=
zuul.host.connect-timeout-millis=15000

 3、给相关模块和网关启动类添加@EnableRedisHttpSession注解，使用Redis存储session

package com.learn.cloud.mall.practice.user;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@SpringBootApplication
@EnableSwagger2
@MapperScan(basePackages = "com.learn.cloud.mall.practice.user.model.dao")
@EnableRedisHttpSession
public class UserApplication {
    public static void main(String[] args) {
        SpringApplication.run(UserApplication.class);
    }
}

package com.learn.cloud.mall.practice.zuul;

import org.springframework.boot.SpringApplication;
import org.springframework.cloud.client.SpringCloudApplication;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
import org.springframework.cloud.openfeign.EnableFeignClients;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;

@SpringCloudApplication
@EnableZuulProxy
@EnableFeignClients
@EnableRedisHttpSession
public class ZuulGatewayApplication {
    public static void main(String[] args) {
        SpringApplication.run(ZuulGatewayApplication.class,args);
    }
}

4、使用

//通过以上配置，直接使用setAttribute方法，即可将session存入Redis中

session.setAttribute(Constant.USER, user);
