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();
}
}
}
