windows - redis内存对象使用

来源：互联网发布：家里网络能连上但没网编辑：程序博客网时间：2024/06/18 11:43

一、下载Redis

下载Redis并解压缩https://redis.io/download
在解压文件夹开启命令行。

G:\Software\redis-64.3.0.503>redis-server.exe redis.windows.conf                _._           _.-``__ ''-._      _.-``    `.  `_.  ''-._           Redis 3.0.503 (00000000/0) 64 bit  .-`` .-```.  ```\/    _.,_ ''-._ (    '      ,       .-`  | `,    )     Running in standalone mode |`-._`-...-` __...-.``-._|'` _.-'|     Port: 6379 |    `-._   `._    /     _.-'    |     PID: 3836  `-._    `-._  `-./  _.-'    _.-' |`-._`-._    `-.__.-'    _.-'_.-'| |    `-._`-._        _.-'_.-'    |           http://redis.io  `-._    `-._`-.__.-'_.-'    _.-' |`-._`-._    `-.__.-'    _.-'_.-'| |    `-._`-._        _.-'_.-'    |  `-._    `-._`-.__.-'_.-'    _.-'      `-._    `-.__.-'    _.-'          `-._        _.-'              `-.__.-'[3836] 29 Nov 16:39:12.287 # Server started, Redis version 3.0.503[3836] 29 Nov 16:39:12.301 * DB loaded from disk: 0.006 seconds[3836] 29 Nov 16:39:12.303 * The server is now ready to accept connections on port 6379

二、测试简单读取写入

参数：
-h 目标主机IP地址
-p 目标主机Redis服务器监听端口

G:\Software\redis-64.3.0.503>redis-cli.exe -h 127.0.0.1 -p 6379127.0.0.1:6379> set me wyfOK127.0.0.1:6379> get me"wyf"

三、maven web程序中使用redis

pom.xml添加依赖包

    <!-- https://mvnrepository.com/artifact/redis.clients/jedis -->    <dependency>        <groupId>redis.clients</groupId>        <artifactId>jedis</artifactId>        <version>2.9.0</version>    </dependency>    <!-- https://mvnrepository.com/artifact/org.apache.commons/commons-pool2 -->    <dependency>        <groupId>org.apache.commons</groupId>        <artifactId>commons-pool2</artifactId>        <version>2.4.2</version>    </dependency>

简单的使用，创建Jedis对象传入主机IP地址，端口。并通过get方法获取对象。结束后调用close方法关闭
不同的客户端都可以进行访问，因此可以实现内存对象共享功能

    @RequestMapping("/g-greet")    public String greeting(@RequestParam(value="name", required=false, defaultValue="World") String name, Model model) {        String host = "127.0.0.1";        int port = 6379;        Jedis jedis = new Jedis(host,port);        String strInRedis = jedis.get(name);        jedis.close();                model.addAttribute("name", strInRedis);        return "greeting";    }
