redis 创建套接字失败

Question

遇到redis连接问题。配置了主机和端口，docker中的redis容器工作正常，我不知道为什么会发生这个异常。

我如何运行此测试：

使用 redis 运行 docker 容器 -> 进入 redis cli 并执行“redis-server”

在我进行测试之后。

附注redis 在控制台中运行良好

redis 控制台：

测试

@SpringBootTest
class MessengerApplicationTests {

    @Test
    void contextLoads() {
        Jedis jedis = new Jedis();

        System.out.println(jedis.keys("*"));
    }

}

异常

    host: localhost

Answer 1

我使用了错误的端口，因为我有一个企业版，它有三个不同的端口

Answer 2

这对我有帮助

docker run -d -p 6379:6379 --name my_redis redis

同时设置超时

Jedis jedis = new Jedis("localhost",6379,3600);
