flex通过java后台获取ip和pcname示例代码

Tags: flex
在***DAOImpl.java中的代码如下

public String getCompuName()
{
Map<String, String> map = System.getenv() ;
String computerName = map.get("COMPUTERNAME");// 获取计算机名
return computerName;
}
public String getIp()
{
InetAddress addr = null;
try {
addr = InetAddress.getLocalHost();
}
catch (UnknownHostException e)
{
e.printStackTrace();
}
String ip = addr.getHostAddress().toString();//获得本机IP
return ip;
}

需要引入

import java.util.Map;
import java.net.InetAddress;
import java.net.UnknownHostException;
