Java java.net.ConnectException：连接被拒绝 [英] Java java.net.ConnectException: Connection refused

问题描述

将应用程序复制到服务器时遇到问题。
程序在我的测试机器（Mac OS X）上正常运行，但是当我在我的服务器（Windows Server 2008）上部署它时，我收到以下错误：

I'm having an issue when copying my application to the server. The program runs fine on my testing machine (Mac OS X), but when I deploy it on my server (Windows Server 2008), I get the following error:

java.net.ConnectException：拒绝连接

java.net.ConnectException: Connection refused

我确定我已打开正确用于出站连接的端口。只是80端口？

I'm sure I've open the ports correctly for outbound connections. Just port 80 right?

这是一个代码片段，如果有帮助

Here's a code snippet if it helps

try {
    doc = Jsoup.connect("http://google.com").get();
} catch (IOException e) {
    e.printStackTrace();
    return;
}

Java不是我的主要语言，所以让我知道是否还有更多你需要。

Java isn't my main language, so let me know if there's anything more you need.

推荐答案

由于以下两个原因之一，这个问题几乎总是出现：

1）服务器没有在正确的端口上侦听

2）你有防火墙可以阻止交通

This problem almost always came up because of one of two reasons:
1) The server is not listening on right port
2) You have firewall which blocks out trafic

尝试暂时停止防火墙，看看发生了什么。

Try to stop your firewall temporarily and see what's going on.
