修改IP地址

利用windows api的操作对IP的设置进行管理。

public class IPBean {
	private String newIP;
	private String mask;
	private String gateway;

	public void setNewIP(String newIP) {
		this.newIP = newIP;
	}

	public void setMask(String mask) {
		this.mask = mask;
	}

	public void setGateway(String gateway) {
		this.gateway = gateway;
	}

	public IPBean() {
	}

	public IPBean(String newIP, String mask, String gateway) {
		this.newIP = newIP;
		this.mask = mask;
		this.gateway = gateway;
	}

	public String execute() throws Exception {
		// 利用进程来修改IP
		String result = "";
		try {
			String command = "netsh interface ip set addr \"本地连接\" static "
					+ newIP + " " + mask + " " + gateway + " 1";
			Process pc = Runtime.getRuntime().exec(command);
			InputStreamReader is = new InputStreamReader(pc.getInputStream());

			LineNumberReader line = new LineNumberReader(is);
			String str = null;
			while ((str = line.readLine()) != null) {
				result += str;
			}
		} catch (Exception e) {
			result = e.toString();
		}
		return result;
	}
}

public class IPUtil {
	public static void main(String[] args) {
		IPBean bean = new IPBean();
		
		//设置IP
		bean.setNewIP("*********");
		//设置子网掩码
		bean.setMask("**********");
		//设置默认网关
		bean.setGateway("*********");
		
		System.out.println("the process is running...");
		
		try {
			String result = bean.execute();
			if(result==null||result.trim().equals("")){
				System.out.println("Success");
				System.exit(0);
			}
			System.out.println(result);
		} catch (Exception ex) {
			System.err.println(ex.toString());
		}
	}
}
