本文介绍了一个使用 Spring Data Redis 进行数据库连接的例子，演示了如何配置 JedisConnectionFactory 和通过它获取 RedisConnection 对象。此外，还展示了如何使用 RedisConnection 的 zRevRangeByScore 方法来操作有序集合。

Redis RedisConnection 例子

import java.util.Iterator;
import java.util.Set;

import org.springframework.data.redis.connection.RedisConnection;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;

public class TestRedisProblem {

   private static JedisConnectionFactory getJedisConnectionFactory() {
       JedisConnectionFactory jcf = new JedisConnectionFactory();
       jcf.setHostName("127.0.0.1");
       jcf.setPort(6379);
       jcf.setPassword("123");
       jcf.afterPropertiesSet();
       return jcf;
   }

   private static RedisConnection getRedisConnection() {
       return getJedisConnectionFactory().getConnection();
   }

   public static void main(String[] args) {
       RedisConnection rc = getRedisConnection();

       Set<byte[]> score = rc.zRevRangeByScore("score:".getBytes(), 0, 0);
//       Set<byte[]> score = rc.zRevRange("score:".getBytes(), 0, -1);
       System.out.println(score.size());
       Iterator<byte[]> it = score.iterator();
       while (it.hasNext()) {
           System.out.println("score: [" + new String(it.next()) + "]");
       }

       rc.zRevRangeByScoreWithScores("score:".getBytes(), 1, 100);


//       double a = 1.0;
//       System.out.println(String.valueOf(a));
//       System.out.println(String.v);
