或者用pom.xml配置jar

<dependency>
                <groupId>redis.clients</groupId>
                <artifactId>jedis</artifactId>
                <version>2.9.0</version>
            </dependency>

jedis配置类ConnectionManager 用于配置获取jedis

import redis.clients.jedis.Jedis;
    import redis.clients.jedis.JedisPool;
    import redis.clients.jedis.JedisPoolConfig;
    
    public class ConnectionManager { 
    
        private static final String redis_host = "127.0.0.1";
        private static final int redis_port = 6379;
        private static final int redis_timeout = 2000;
        private static final String redis_password = "pwd";
    
        private static JedisPool pool;
    
        static {
            JedisPoolConfig config = new JedisPoolConfig();
            // 控制一个pool可分配多少个jedis实例，通过pool.getResource()来获取；
            // pool = new JedisPool(config, redis_host, 6379);
            pool = new JedisPool(config, redis_host, redis_port, redis_timeout, redis_password);
        }
    
        public static void main(String[] args) throws Exception {
            pool = new JedisPool(new JedisPoolConfig(), redis_host, redis_port, 3000, redis_password);
            Jedis jedis = pool.getResource();
            jedis.set("a", "abc");
            System.out.println("redis中的值：" + jedis.get("a"));
    
            closeConnection(jedis);
        }
        /** * 获取连接 * @return * @throws Exception */
        public static synchronized Jedis getConnection() throws Exception {
            try {
                return pool.getResource();
            } catch (Exception e) {
                throw e;
            }
        }
        /** * 关闭连接 * @param connection * @throws Exception */
        public static synchronized void closeConnection(Jedis connection) throws Exception {
            try {
                if (connection != null && connection.isConnected()) {
                    connection.close();
                }
            } catch (Exception e) {
                throw e;
            }
        }
    
    }
