JNI vs Runtime.exec（） [英] JNI vs Runtime.exec()

问题描述

我有两个选择 - 我可以使用JNI或使用Runtime.exec来执行C ++库。

I have two options - I can either use JNI or use Runtime.exec to execute a C++ library.

C ++程序是CPU密集型的并且长期运行，即一些电话可能需要几个小时才能返回。

The C++ program is CPU intensive and long running i.e. some calls may take up to a couple of hours to return.

每种电话的优缺点是什么？
我应该采用哪种方法？

What are the pros and cons of each? Which approach should I go for?

推荐答案

如果您需要与C ++库进行交互，请转到JNI。

If you need to interact with the C++ library, go for JNI.

如果它是一个你想要调用的独立程序（也许是获取输出）， Runtime.exec（）更简单。

If it's a standalone program that you just want to invoke (and perhaps grab the output), Runtime.exec() is much, much simpler.
