首先下载redis客户端

**下载地址：**[https://github.com/tporadowski/redis/releases][https_github.com_tporadowski_redis_releases]。

然后我们根据自己电脑的操作系统下载自己需要的压缩包

下载下来后解压

然后我们通过cmd命令去启动redis；

redis-server.exe redis.windows.conf

这里我们可以看到启动成功了，端口号默认是6379

然后我们写一段redis连接的代码去测试。

package com.example;
    
    import org.apache.commons.pool2.impl.GenericObjectPoolConfig;
    import redis.clients.jedis.Jedis;
    import redis.clients.jedis.JedisPool;
    
    /**

     */
    public class TestJedis {
    
        public static void main(String[] args) {
            GenericObjectPoolConfig poolConfig = new GenericObjectPoolConfig();
            JedisPool jedisPool = new JedisPool(poolConfig, "127.0.0.1", 6379);
            Jedis jedis = null;
            try {
                // 1. 从连接池获取jedis对象
                jedis = jedisPool.getResource();
                jedis.set("hello", "world");
                // 2. 执行操作
                String a = jedis.get("hello");
                System.out.println(a);
            } catch (Exception e) {
                e.printStackTrace();
            } finally {
                if (jedis != null) {
                    // 如果使用JedisPool，close操作不是关闭连接，代表归还连接池
                    jedis.close();
                }
            }
        }
    }

运行查看打印
