在Java中解析命令行参数的好方法是什么?
当前回答
Argparse4j是我发现的最好的。它模仿Python的argparse库,非常方便和强大。

我使用过JOpt,发现它非常方便:http://jopt-simple.sourceforge.net/
首页还提供了一个大约8个备选库的列表,检查它们并选择最适合您的需求。
我想向您展示我的实现:ReadyCLI
优点:
for lazy programmers: a very small number of classes to learn, just see the two small examples on the README in the repository and you are already at 90% of learning; just start coding your CLI/Parser without any other knowledge; ReadyCLI allows coding CLIs in the most natural way; it is designed with Developer Experience in mind; it largely uses the Builder design pattern and functional interfaces for Lambda Expressions, to allow a very quick coding; it supports Options, Flags and Sub-Commands; it allows to parse arguments from command-line and to build more complex and interactive CLIs; a CLI can be started on Standard I/O just as easily as on any other I/O interface, such as sockets; it gives great support for documentation of commands.
我开发这个项目是因为我需要新的功能(选项,标志,子命令),并且可以在我的项目中以最简单的方式使用。
For Spring users, we should mention also https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/core/env/SimpleCommandLinePropertySource.html and his twin brother https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/core/env/JOptCommandLinePropertySource.html (JOpt implementation of the same functionality). The advantage in Spring is that you can directly bind the command line arguments to attributes, there is an example here https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/core/env/CommandLinePropertySource.html
我又写了一个:http://argparse4j.sourceforge.net/
Argparse4j是Java的命令行参数解析器库,基于Python的argparse。
