使用Apache的CLI处理命令行

需要commons-cli-1.0.jar。
使用 OptionsCLI -h
     OptionsCLI -u ** -p **

import org.apache.commons.cli.BasicParser;
import org.apache.commons.cli.CommandLine;
import org.apache.commons.cli.HelpFormatter;
import org.apache.commons.cli.Options;
import org.apache.commons.cli.ParseException;

public class OptionsCLI {
	public static void main(String[] args) {
			Options opts = new Options();
			opts.addOption("h", false, " help ");
			opts.addOption("u", true, " user");
			opts.addOption("p", true, " password");
			BasicParser parser = new BasicParser();
			CommandLine cl;
			try {
				cl = parser.parse(opts, args);
				if (cl.hasOption('h')) {
					HelpFormatter hf = new HelpFormatter();
					hf.printHelp("Options", opts);
				} else {
					System.out.println(cl.getOptionValue("u"));
					System.out.println(cl.getOptionValue("p"));
				}
			} catch (ParseException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}

	}
