flex通过java后台获取ip和pcname示例代码

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;
