JNI 与 Runtime.exec()

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++ 程序占用大量 CPU 资源且运行时间较长,即某些调用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.

各有什么优缺点?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

如果需要与 C++ 库交互,请选择 JNI.

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

如果它是您只想调用的独立程序(也许还想获取输出),Runtime.exec() 会简单得多.

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