redis--->jedis

链接redis的中间件

导入依赖

<!-- https://mvnrepository.com/artifact/redis.clients/jedis -->
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>3.5.1</version>
</dependency>
// fastjson
<!-- https://mvnrepository.com/artifact/com.alibaba/fastjson -->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.75</version>
</dependency>

java  

Jedis  jedis=new Jedis("127.0.0.1",6379);    //获取链接

jsonobject  jsonobject=new jsonobject();
jsonobject.put("hello","world");

//开启事务
Transaction  multi=jedis.multi();

String str =jsonobject.tojsonstring();    //将JSON转换为字符串
multi.set("user1",str);

multi.exec();       //执行事务

multi.discard();   //放弃事务
jedis.close();       //关闭链接

所有的命令和redis是一样的

jedis.**** 是一样的
