SpringBoot或Maven整合测试 Redis是否连接

用Java代码使用Jedis操作Redis

<!-- Jedis依赖 -->
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>3.6.3</version>
</dependency>

1、注销掉bind 127.0.0.1 #本机访问安全模式不带打开protected-mode no redis.conf中配置

systemctl status firewalld   :查看防火墙是否代开
systemctl stop firewalld  :关闭防火墙

2、查看是否连接到Redis

public class JedisDemo {
    public static void main(String[] args) {
         //1创建Jedis对象
        Jedis jedis = new Jedis("124.222.69.61",6379);
        String ping = jedis.ping();
        System.out.println("连接成功");
    }
}

3、如果出现 Exception in thread "main" redis.clients.jedis.exceptions.JedisConnectionException: Failed to create socket.异常

解决方案：关闭云服务器的防火墙  不要再连接工具里关  去 阿里云或腾讯云关闭
