配置文件redisConfig.properties：

redis.host=10.15.1.19
redis.port=16379
# auth:0不需要密码；1需要密码
redis.authFlag=1
redis.password=wC3Xo8E5mlmgMb

测试代码：

 package StudyPro.service;

 import org.junit.Test;
 import redis.clients.jedis.Jedis;

 public class TestRedisUtils {
     @Test
     public void test() {
         Jedis jedis = RedisUtils.getResource();
 //        jedis.auth("wC3Xo8E5mlmgMb");
         System.out.println(jedis.get("a"));
         jedis.close();
         RedisUtils.close();

     }
