如何使命令行参数既不运行，又不运行，又不运行？ -Java [英] How do I make command line arguments run with either, neither, or both arguments? - Java

问题描述

我正在制作一个硒Web驱动程序，我有25个应用程序和4个环境。我将它们设置为枚举，以便提供特定的命令行参数。现在，我可以正常运行它，以便该应用程序需要一个应用程序，然后需要一个环境。我需要能够做

I am making a selenium webdriver and I have 25 apps and 4 environments. I have them set up as enums so I can give specific command line arguments. Right now I have it working so that it takes one app and then one environment in that order. I need to be able to do something like

-app app1 app2 app3 -env env1 env2

我需要它不带参数，带参数或带两个参数。

I need it to either take no arguments, either arguments, or both arguments. This is what I have so far.

if (args.length == 0)
{
    LogIn.loginTest(testResults);
    DatabaseTest.testResults(testResults);
    LinkTest.linkTests(testResults);
}
else 
{
    // First choose application, then choose environment
    Application.chooseAppTest(args);
}

推荐答案

考虑使用库进行评估您的命令行参数，例如 JOptSimple 。他们在他们的网站上提供了一组不错的示例，而您不必重新发明轮子。按照您的示例，根据文档（尚未尝试过），以下应该可以工作：

Consider using a library for evaluating your command line arguments, like JOptSimple. They provide a nice set of examples on their website and you wouldn't have to re-invent the wheel. Adopting to your example, the following should work, according to the documentation (haven't tried it out):

OptionParser parser = new OptionParser("app:env:");
OptionSet options = parser.parse("-app", "app1", "app2", "app3", "-env", "env1", "env2");

options.valuesOf（ app）然后应返回 app1， app2和 app3的列表。

options.valuesOf("app") should then return a list of "app1", "app2", and "app3".
