Redis redis use in jedis

Preface

I won't post Baidu's conceptual solutions , Simply speaking ,Jedis yes Redis Officially recommended Java Connect development tools ！  Although the present SpringBoot2.× The version has already Jedis Instead of Lettuce, But I think it's still necessary to know Jedis Use ！

1. How to be in java Integration in the project Jedis And connect Redis database ？

① Create a Maven project

② Import Jedis and fastjson rely on , Wait patiently for the download to complete ！

<!-- Import jedis My bag -->
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>3.2.0</version>
</dependency> 
<!--fastjson-->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.62</version>
 </dependency>

③ Connect Redis test , Here for the convenience of testing , The connection is local Redis service , Connecting to the remote requires changing the configuration file and turning off the firewall , In the future, I will write a separate article to introduce this ！

// 1、 new Jedis  Object can 
Jedis jedis = new Jedis("127.0.0.1",6379);
// jedis  All commands are all our previous commands 
System.out.println(jedis.ping());

Pictured ：

return PONG, Prove that the connection was successful ！

④ frequently-used API practice ：

 		// 1、 new Jedis  Object can 
        Jedis jedis = new Jedis("127.0.0.1",6379);
        jedis.flushDB();// Clear all data in the current library 
        jedis.set("name","dingyongjun");
        jedis.set("age","23");
        jedis.set("high","173");
        System.out.println("name:"+jedis.get("name")+"\nage:"+jedis.get("age")+"\nhigh"+jedis.get("high"));

Pictured ：

		jedis.lpush("list","1","2","3","4");
        System.out.println("list: "+jedis.lrange("list",0,-1));

 

 ⑤ summary ： stay Jedis Middle connection use Redis, and Redis Console commands are completely consistent
