Redis-Java 交互的应用

一、首先介绍一下 Redis

      Redis 是目前业界使用最广泛的内存数据存储。相比 memcached，Redis 支持更丰富的数据结构，例如 hashes, lists, sets 等，同时支持数据持久化。除此之外，Redis 还提供一些类数据库的特性，比如事务，HA，主从库。可以说 Redis 兼具了缓存系统和数据库的一些特性，因此有着丰富的应用场景。本文介绍 Redis 在 Spring Boot 中典型的应用场景。

       Redis 缓存数据类型有 5 种，分别是 String（字符串）、List（列表）、Hash（哈希）、Set（无序，不重复集合）、ZSet（sorted set：有序，不重复集合）。

二、先下载 redis  我这里使用的是 window64 版本

  这是教程链接： http://blog.csdn.net/jinwufeiyang/article/details/52156817

  Redis 下载链接 ：https://github.com/MicrosoftArchive/redis/releases

 

 

 

     双击图上的标记的 ，如成功便如图下

 

 

 三、下面介绍 java 如何配置

    这是我的项目结构

        

 

        首先 pom 中引入 jar 包

   

  <!-- 共享 Session-spring-session-data-redis 分布式系统中，
         sessiong 共享有很多的解决方案，其中托管到缓存中应该是最常用的方案之一-->
        <dependency>
            <groupId>org.springframework.session</groupId>
            <artifactId>spring-session-data-redis</artifactId>
        </dependency>

    

       application.properties 配置

    

# default-store in spring session. it will be set in redis only outside.
spring.session.store-type=none
# REDIS (RedisProperties)
# Redis 数据库索引（默认为 0）
spring.redis.database=0  
# Redis 服务器地址
spring.redis.host=127.0.0.1
# Redis 服务器连接端口
spring.redis.port=6379  
# Redis 服务器连接密码（默认为空）
spring.redis.password=
# 连接池最大连接数（使用负值表示没有限制）
spring.redis.pool.max-active=8  
# 连接池最大阻塞等待时间（使用负值表示没有限制）
spring.redis.pool.max-wait=-1  
# 连接池中的最大空闲连接
spring.redis.pool.max-idle=8  
# 连接池中的最小空闲连接
spring.redis.pool.min-idle=0  
# 连接超时时间（毫秒）
spring.redis.timeout=0

  

     RedisController 配置

@RestController
public class RedisController {

     Redis  实现 session 共享  sessionConfig 配置

@Configuration
@EnableRedisHttpSession(maxInactiveIntervalInSeconds = 86400*30)
public class SessionConfig {
}

 

     调用方法

HttpSession session；
session.setAttribute("data", "Session 共享 9966");
String name = "端口号：9966========="+ session.getAttribute("data");

 

   分别运行两个一样的配置 session 就共享了

     源码  良心制作 ：https://gitee.com/xdymemory00/FuZaiJunHeng_Redis_session-GongXiang

     nginx +Redis window64 版本工具：https://gitee.com/xdymemory00/Redis_Nginx-GongJu.git

 

 

运行之后收工！！！！！！！！！！
