命令行解析：Commons CLI备用？ [英] Command Line Parsing: Commons CLI alternatives?

问题描述

对于Java中的命令行解析，我通常使用 Apache Commons CLI 。
任何人都可以推荐任何替代库？

For Command Line parsing in Java, I typically use Apache Commons CLI. Can anybody recommend any alternative libraries?

推荐答案

JCommander 听起来像一个非常简单而有趣的解析命令行参数与注释（来自TestNG的创建者）的方法：

JCommander sounds like a very simple and interesting approach to parsing command line arguments with annotations (from the creator of TestNG):

您可以使用选项的描述注释字段：

You annotate fields with descriptions of your options:

import com.beust.jcommander.Parameter;

public class JCommanderTest {
  @Parameter
  public List<String> parameters = Lists.newArrayList();

  @Parameter(names = { "-log", "-verbose" }, description = "Level of verbosity")
  public Integer verbose = 1;

  @Parameter(names = "-groups", description = "Comma-separated list of group names to be run")
  public String groups;

  @Parameter(names = "-debug", description = "Debug mode")
  public boolean debug = false;
}

然后你只需要让JCommander解析：

and then you simply ask JCommander to parse:

JCommanderTest jct = new JCommanderTest();
String[] argv = { "-log", "2", "-groups", "unit", "a", "b", "c" };
new JCommander(jct, argv);

Assert.assertEquals(jct.verbose.intValue(), 2);
