jmeter连接redis取数据

import com.alibaba.fastjson.JSON;
import redis.clients.jedis.Jedis;
import com.alibaba.fastjson.JSONObject;

//String redis_ip = vars.get("redis_ip");
//int redis_port = vars.get("redis_port");
//String redis_pswd = vars.get("redis_pswd");

// redis ip port
Jedis jedis = new Jedis("ip", port);

// redis 密码
jedis.auth("passwd");

// 要取数据所在的第几个数据库
int index = 9;
jedis.select(index);

// 根据hash id 获取值并解析
String va = jedis.hget("MERCHANT:LOGIN:TOKEN","35C871EFF223403910F031FE33B0125B7C8C60426737CC14CC58BD40CF3C0666");
JSONObject jo = JSON.parseObject(new String(va));

// 根据 key 获取值
String json_value = jo.getString("ttoken");

vars.put("ttoken", json_value);
