Java调用Python脚本
Jython主页:http://www.jython.org/
Jython是Python语言在Java平台的实现,本质上,Jython是由Java编写,其是在JVM上实现的Python语言。因此,可以直接通过Jython在Java中调用Python。
引入jython依赖
<dependency> <groupId>org.python</groupId> <artifactId>jython-standalone</artifactId> <version>2.7.0</version> </dependency>
Example
public static void main(String[] args) {
PythonInterpreter interpreter = new PythonInterpreter();
//执行python
interpreter.exec("print (10086)");
}
Run Python File demo.py
// init PythonInterpreter PythonInterpreter interpreter = new PythonInterpreter(); // catch File Exception try{ InputStream filepy = new FileInputStream("D:xxx.py"); // run python file interpreter.execfile(filepy); }catch (Exception e){ e.printStackTrace(); }finally { interpreter.close(); }
获取函数名
//获取函数名test PyFunction pyf = inter.get("test", PyFunction.class); //向函数中传递参数并获取返回结果 PyObject res = pyf.__call__(Py.newInteger(2), Py.newInteger(3)); System.out.print(res); inter.cleanup(); inter.close();
