Apache Commons CLI - Posix 解析器

Posix 解析器用于解析传递的参数等 Posix。它现已被弃用并被 DefaultParser 取代。

例子

CLITester.java

import org.apache.commons.cli.CommandLine;
import org.apache.commons.cli.CommandLineParser;
import org.apache.commons.cli.Options;
import org.apache.commons.cli.ParseException;
import org.apache.commons.cli.PosixParser;

public class CLITester {
   public static void main(String[] args) throws ParseException {
      
      //Create posix like options
      Options posixOptions = new Options();
      posixOptions.addOption("D", false, "Display");
      posixOptions.addOption("A", false, "Act");
      
      CommandLineParser posixParser = new PosixParser();
      
      CommandLine cmd = posixParser.parse(posixOptions, args);
      
      if( cmd.hasOption("D") ) {
         System.out.println("D option was used.");
      }
      if( cmd.hasOption("A") ) {
         System.out.println("A option was used.");
      }
   }
