Java获取本地服务器的IP

        System.out.println("getRequestURL:"+request.getRequestURL());
		System.out.println("getLocalAddr:"+request.getLocalAddr());
		System.out.println("getLocalPort:"+request.getLocalPort());
		System.out.println("getRequestURI:"+request.getRequestURI());
		System.out.println("getScheme:"+request.getScheme());
		System.out.println("getServerPort:"+request.getServerPort());
		System.out.println("getServletPath:"+request.getServletPath());
		try {
			InetAddress addr = InetAddress.getLocalHost();
            byte[] ipAddr = addr.getAddress();     
            String ipAddrStr = "";
            for (int i = 0; i < ipAddr.length; i++) {  
            	if (i > 0) {  
            		ipAddrStr += ".";  
            	}
            	ipAddrStr += ipAddr[i] & 0xFF; 
            }
            System.out.println(ipAddrStr);
		} catch (UnknownHostException e1) {
			e1.printStackTrace();
		}
//输出：
/*
