由于我测试的redis的环境是集群环境，故声明多个Jedis对象，下面是实现代码

package com.gyc.test;import java.util.Iterator;import java.util.Set;import org.junit.Before;import org.junit.Test;import redis.clients.jedis.Jedis;public class TestRedis {private Jedis jedis;private Jedis jedis1;private Jedis jedis2;private Jedis jedis3;private String pre_str = "a";//redis的key的前缀@Beforepublic void setup() {System.out.println("---------------------------------setup------------------");// 连接redis服务器，127.0.0.1:6379// jedis = new Jedis("127.0.0.1", 6379);jedis1 = new Jedis("127.0.0.1", 6377);jedis2 = new Jedis("127.0.0.2", 6378);jedis3 = new Jedis("127.0.0.3", 6379);// 权限认证// jedis.auth("admin");}/** * redis批量删除以某字符串前缀的key */@Testpublic void testBatchDel() {System.out.println("---------------------------------testBatchDel------------------");batchDel(jedis1);batchDel(jedis2);batchDel(jedis3);}private void batchDel(Jedis jedis){Set<String> set = jedis.keys(pre_str +"*");Iterator<String> it = set.iterator();while(it.hasNext()){String keyStr = it.next();System.out.println(keyStr);jedis.del(keyStr);}}}
