这篇博客探讨了如何编写代码，以便根据运行的操作系统（Windows, Linux, macOS）执行不同的命令行指令。内容涉及如何检测当前系统，并适配执行相应的shell命令。" 7886338,33208,手动安装Oracle ODAC XCopy步骤详解,"['oracle', 'asp.net', '.net', 'c']

2、执行命令行命令

/**
	 * 运行命令行
	 * @throws Exception
	 */
	public synchronized static void runExecCommand(String cmdStr)  throws Exception{
		String osName = System.getProperty("os.name");
		String cmd = "";
		Process p;
		try{
			if (osName.matches("^(?i)Windows.*$")) {// Window 系统				
				cmd = "  cmd /c "+cmdStr;
				Runtime.getRuntime().exec(cmd);				
			}else{// Linux 系统				
				cmd = ""+cmdStr;
				String[] comands = new String[] { "/bin/sh", "-c", cmd };
				p = Runtime.getRuntime().exec(comands);
			}
			logger.info("exec command to system:"+cmd);
		}catch (Exception e) {
			logger.error("io exec ee....." + e);			
		}finally{
				//p.destroy();			
		}
	}

3、获取本机ip

package common;
import java.net.Inet4Address;
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;
import java.util.Enumeration;

public class IpTest {

	public static String getInet4Address() throws SocketException, UnknownHostException {
		return System.getProperty("os.name").toLowerCase().indexOf("window") > -1 ? getWindowIp() : getUnixIp();
	}

	private static String getWindowIp() throws UnknownHostException {
		return InetAddress.getLocalHost().getHostAddress();
	}

	private static String getUnixIp() throws SocketException {
		Enumeration<NetworkInterface> allNetInterfaces = NetworkInterface.getNetworkInterfaces();
		InetAddress ip = null;
		while (allNetInterfaces.hasMoreElements()) {
			NetworkInterface netInterface = (NetworkInterface) allNetInterfaces.nextElement();
			System.out.println(netInterface.getName());
			Enumeration<InetAddress> addresses = netInterface.getInetAddresses();
			while (addresses.hasMoreElements()) {
				ip = (InetAddress) addresses.nextElement();
				if (ip != null && ip instanceof Inet4Address) {
					System.out.println("本机的IP = " + ip.getHostAddress());
					return ip.getHostAddress();
				}
			}
		}
		return null;
	}

	public static void main(String args[]) throws SocketException, UnknownHostException {
		System.out.println(System.getProperty("os.name"));
		System.out.println(getInet4Address());
	}
}
