Java代码调用python的几种方法

1.利用Jython.jar包

1 PythonInterpreter interpreter = new PythonInterpreter();  
2 InputStream filepy = new FileInputStream("D:\\demo.py"); 
3 interpreter.execfile(filepy);  ///执行python py文件
4 filepy.close();

2.java运行时

Process process=getRuntime().exec("python xxxx.py");

process.waitFor();
