当我跑docker-compose up,我得到这个错误:

我使用Intellij Idea15。我以前使用帐户A将代码提交到github吗？我现在想使用帐户B将代码提交到github。如何切换到其他帐户？

我尝试遵循：在 github 上托管 Maven 存储库

我的 POM.xml

我写了以下代码：

public static void main(String args[]) throws IOException {
    URL url = new URL("http://stackoverflow.com/");
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    System.out.print(conn.getResponseMessage());
}

1. 当我运行此方法时，我想在控制台中显示所有调试信息。
2. 我想看看从日志发送了什么样的 http 请求。
