Jedis第一个Demo

代码部分

 package com.test.jedis;

 import org.junit.Test;
 
 import redis.clients.jedis.Jedis;
 import redis.clients.jedis.JedisPool;
 import redis.clients.jedis.JedisPoolConfig;

 public class JedisTest {
       @Test
       public void testJedis() {
             Jedis jedis = new Jedis("192.168.1.107", 6379);
             jedis.set("name", "admin");
             String name = jedis.get("name");
             System.out.println("name:" + name);
             jedis.close();
         }

       @Test
       public void testJedisPool() {//使用连接池方式
             JedisPoolConfig config = new JedisPoolConfig();
             config.setMaxIdle(23);
             config.setMaxTotal(100);

             JedisPool pool = new JedisPool(config, "192.168.1.107", 6379);
             Jedis jedis = null;
             try {
                   jedis = pool.getResource();
                   jedis.set("name", "wakaka");
                   String name = jedis.get("name");
                   System.out.println("#name:" + name);
             } catch (Exception e) {
                 e.printStackTrace();
             } finally {
                if (jedis != null) {
                    jedis.close();
                 }
                if (pool != null) {
                    pool.close();
                  }
             }
 
      }

}

首次运行报错：connectTimeOut连接数据库超时，检查了一下，虚拟机中centos7的Redis的端口被防火墙过滤了。
解决方法：

1. 将6379端口加入白名单
   vi /etc/sysconfig/iptables

# sample configuration for iptables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default configuration
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 6379 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

6379端口这一行是新增的内容，即
-A INPUT -p tcp -m state --state NEW -m tcp --dport 6379 -j ACCEPT

2. 重启服务
   service iptables restart

3. Windows的cmd打开,测试192.168.1.107的6379端口
   telnet 192.168.1.107 6379
   如果显示连接成功，--->END

   如果显示连接失败，请继续往下看步骤4

4. 检查192.168.1.107中Redis的配置文件
   vi redis.conf
   找到bind 127.0.0.1修改为192.168.1.107。
   再次回到步骤3，测试成功-->END

正在学习Redis，记作笔记，有误请指出。谢谢
