我有一些非常简单的代码,目前正在尝试让this开始启动并运行Spark项目。

我的代码如下所示:

import static spark.Spark.*;

public class Main {
    public static void main(String[] args) {
        get("/hello", (req, res) -> "Hello World");
    }
}

我在运行http://localhost:4567/hello

时遇到此错误
localhost refused to connect.
ERR_CONNECTION_REFUSED

如果需要,还可以使用pom.xml文件

答案 0 :(得分:0)

试试这个:

import static spark.Spark.*;

public class Main {
    private static final int PORT = 8080; // or other not taken port
    public static void main(String[] args) {
        port(PORT);
        get("/hello", (req, res) -> "Hello World");
    }
}

如果这有助于尝试关闭防火墙一段时间,可能会有所帮助。
