以下代码是可以连接的：

  public static void main(String[] paramArrayOfString){
    String HOST = "localhost";
    int PORT = 6379;
    Jedis jedis = new Jedis(HOST, PORT);
    try {
      jedis.set("foo", "bar");
      jedis.get("foo");
      System.out.println("Redis read/write ok.");
    } catch (Exception e) {
      System.err.println("Unable to connect to Redis");
      e.printStackTrace();
    }
  }

环境：
JDK 1.6
jedis-2.9.0.jar
commons-pool2-2.4.2.jar
nutz-integration-jedis-1.r.63.r4.jar (是我用JDK1.6编译出来的)

检查一下redis.properties

老大这么晚了还在。。。
提醒我了，
改成 redis.database=0 可以用了。
但是原来在 JDK1.8 环境，redis.database=1也是可以用的。
请问老大这个是什么原因？

redis.host=localhost
redis.port=6379
redis.timeout=2000
#redis.password=
redis.database=0
#redis.mode=cluster

@netexe 不像这个原因

redis版本多少

JDK 1.6
nutz-1.b.49-jdk1.6.jar
nutz-integration-jedis-1.r.63.r4-jdk1.6.jar
Redis 3.2.100 64 bit, standalone mode, port 6379 （Windows 10 64位）

JDK 1.8 的时候确实可以使用 database=1

题外话：
nutz的版本有点低，老的应用系统要加redis缓存功能，升级到 nutz 1.r.63 又一堆问题，没法子。

哦，那就先用着吧

谢谢。顺便问一下，有什么插件可以配置nutz-integration-jedis做超时管理的？

指什么的超时呢?

redis.timeout=1000 这个?

redis缓存超时，比如一个token登录以后，20分钟没有动作自动清理的。

那是redis的命令啊,可以设置过期时间的

我是小白，见笑了。。。

@netexe 看看wkcache , https://gitee.com/nutz/nutzmore/tree/master/nutz-plugins-wkcache

JDK 1.6， redis dbIndex = 1 时，
需要使用 jedis 2.8.x 版本，
jedis 2.9 会连接不上
