简单调用

package com.foamvalue.test;

import redis.clients.jedis.Jedis;

public class RedisTest {

  public static void test() {
    Jedis jedis = null;
    try {
      jedis = new Jedis("localhost", 6379);
      jedis.set("foo", "bar");
      String value = jedis.get("foo");

      System.out.println(value);
    } catch (Exception e) {
      e.printStackTrace();
    } finally {
      if (jedis != null) {
        jedis.close();
      }
    }
  }

  public static void main(String[] args) {
    test();
  }

}
