用Java调用Python？ [英] Calling Python in Java?

问题描述

我想知道是否可以使用jython从java代码调用python函数，还是仅用于从python调用java代码？

I am wondering if it is possible to call python functions from java code using jython, or is it only for calling java code from python?

推荐答案

Jython：Java平台的Python - http://www.jython.org/index .html

您可以使用Jython从Java代码轻松调用python函数。只要您的python代码本身在jython下运行，即不使用一些不受支持的c扩展名。

You can easily call python functions from Java code with Jython. That is as long as your python code itself runs under jython, i.e. doesn't use some c-extensions that aren't supported.

如果这对您有用，那就是当然，你可以得到最简单的解决方案。否则，您可以从新的Java6解释器支持中使用 org.python.util.PythonInterpreter 。

If that works for you, it's certainly the simplest solution you can get. Otherwise you can use org.python.util.PythonInterpreter from the new Java6 interpreter support.

一个简单的例子来自我的头脑 - 但应该工作我希望:(没有为简洁而做错误检查）

A simple example from the top of my head - but should work I hope: (no error checking done for brevity)

PythonInterpreter interpreter = new PythonInterpreter();
interpreter.exec("import sys\nsys.path.append('pathToModules if they are not there by default')\nimport yourModule");
// execute a function that takes a string and returns a string
PyObject someFunc = interpreter.get("funcName");
PyObject result = someFunc.__call__(new PyString("Test!"));
String realResult = (String) result.__tojava__(String.class);
