java连接Redis

pom.xml添加依赖

 <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>2.4.2</version>
        </dependency> 

linux设置密码，指令为：

config set requirepass password(自己设置的password)

开启端口号，重启防火墙，指令参考如下：

Java代码

package com.edu.demo1;

import org.junit.Test;

import redis.clients.jedis.Jedis;

public class redis {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Jedis js=new Jedis("192.168.117.128",6379);
	
		js.auth("yao");
		System.out.println(js.ping());
	}
	@Test
	public void t2() {
		Jedis js=new Jedis("192.168.117.128",6379);
		js.auth("yao");
		String key="application";
		if(js.exists(key)) {
			String result=js.get(key);
			System.out.println("Redis中的数据为："+result);
			
		}else {
			String sqlResult="从MySql查到了";
			js.set(key, sqlResult);
			System.out.println("Mysql中的数据为："+sqlResult);
			
		}
		
	}

}
