【从0到1进阶Redis】Jedis 理解事务

笔记内容来自B站博主《遇见狂神说》：Redis视频链接

小伙伴们可以熟悉一下本专栏的 Redis 文章，可以更好地理解

正常操作

package oldfe.study;import com.alibaba.fastjson.JSONObject;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.Transaction;public class Main {public static void main(String[] args) {Jedis jedis = new Jedis("127.0.0.1", 6379);jedis.auth("123456");jedis.flushDB();JSONObject jsonObject = new JSONObject();jsonObject.put("name", "叫我OldFe");jsonObject.put("age", 16);String result = jsonObject.toJSONString();// 开启事务Transaction multi = jedis.multi();try {multi.set("info", result);multi.set("info1", result);multi.exec();   // 执行事务} catch (Exception e) {multi.discard();    // 放弃事务e.printStackTrace();} finally {System.out.println("info=" + jedis.get("info"));System.out.println("info1=" + jedis.get("info1"));jedis.close();  // 关闭连接}}
}
// 输出：
info={"name":"叫我OldFe","age":16}
info1={"name":"叫我OldFe","age":16}

执行异常
