工具类

public class RedisUtil {
	private static JedisPool pool;

	public static Jedis getJedis() {
		if (pool == null) {
			init();
		}
		return pool.getResource();
	}

	private static void init() {
		ResourceBundle bundle = ResourceBundle.getBundle("redis");
		String host = bundle.getString("host");
		Integer port = Integer.parseInt(bundle.getString("port"));
		Integer maxTotal = Integer.parseInt(bundle.getString("MaxTotal"));
		Integer maxIdle = Integer.parseInt(bundle.getString("MaxIdle"));

		JedisPoolConfig config = new JedisPoolConfig();
		config.setMaxIdle(maxIdle);
		config.setMaxTotal(maxTotal);
		pool = new JedisPool(config, host, port);
	}
}

redis.properties

host=localhost
port=6379
MaxTotal=50
MaxIdle=20

测试代码

public void fun1() {
	Jedis jedis = RedisUtil.getJedis();
	jedis.set("A", "你好，世界！");
	System.out.println(jedis.get("A"));
	jedis.close();
}
