如何在Java中获取Windows用户名？ [英] How to get Windows username in Java?

问题描述

所以我想要做的就是让我的Java找到Windows登录的用户名，所以当我说这样的方法时，它会返回用户名，就像我在名为Noah的用户中使用它一样，java会返回Noah，如果我在用户Amanda上，Java会返回Amanda。我该怎么做？

So what I am trying to do is let my Java find the user's name that windows is logged in with, so when I would say such a method, it would return the users name, like I use it in the User called Noah, java would return "Noah" and if I were on the user Amanda, Java would return "Amanda". How would I do this?

推荐答案

查找系统属性user.name。

Lookup the system property "user.name".

String username = System.getProperty("user.name");

• 系统属性


• System.getProperty


• System Properties
• System.getProperty

演示： Main.java

public class Main {
   public static void main(String[] args) {
      System.out.println(System.getProperty("user.name"));
   }
}

输出：

c:\dev\src\misc>javac Main.java

c:\dev\src\misc>java Main
rgettman

c:\dev\src\misc>
