redis 创建套接字失败

Question

Redis 连接遇到问题。主机和端口已配置，docker 中的 redis 容器工作正常，我不知道为什么会出现此异常。

我如何运行这个测试：

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

cli 截图：

经过我运行的测试。

P.S。 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
