这里

Below is my code
下面是我的代码
final String user = System.getProperty("user.name");
logger.info("User Name : " + user);
I want to know how System.getProperty works in java and on windows server 2008? and why is it returning wrong value in this case?
我想知道 System.getProperty 如何在 java 和 windows server 2008 上工作？为什么在这种情况下它返回错误的值？

Just checked this: System.getProperty("user.name");returns the value from environment variable USERNAME, so check what set USERNAMEsays in CMD window
刚刚检查了这个：System.getProperty("user.name");从环境变量返回值USERNAME，所以检查set USERNAMECMD 窗口中的内容

to display list of all properties that are set in java, try the below code
要显示在 java 中设置的所有属性的列表，请尝试以下代码
public static void main(String[] args)
{
Properties prop = System.getProperties();
Set<String> a = prop.stringPropertyNames();
Iterator<String> keys = a.iterator();
while (keys.hasNext())
{
String key = keys.next();
String value = System.getProperty(key);
System.out.println(key + "=" + value);
}
}
