1、http://sourceforge.net/projects/jython/下载jython包,把其中的jython.jar添加到工程目录
示例:
1、摘自:http://blog.csdn.net/anbo724/article/details/6608632
1.在java类中直接执行python语句
- import javax.script.*;
-
- import org.python.util.PythonInterpreter;
-
- import java.io.*;
- import static java.lang.System.*;
- public class FirstJavaScript
- {
- public static void main(String args[])
- {
-
- PythonInterpreter interpreter = new PythonInterpreter();
- interpreter.exec("days=('mod','Tue','Wed','Thu','Fri','Sat','Sun'); ");
- interpreter.exec("print days[1];");
-
-
- }//main
- }
这样得到的结果是Tue,在控制台显示出来,这是直接进行调用的。
2.在java中调用本机python脚本中的函数:
首先建立一个python脚本,名字为:my_utils.py
- def adder(a, b):
- return a + b
然后建立一个java类,用来测试,
java类代码 FirstJavaScript:
- import javax.script.*;
-
- import org.python.core.PyFunction;
- import org.python.core.PyInteger;
- import org.python.core.PyObject;
- import org.python.util.PythonInterpreter;
-
- import java.io.*;
- import static java.lang.System.*;
- public class FirstJavaScript
- {
- public static void main(String args[])
- {
-
- PythonInterpreter interpreter = new PythonInterpreter();
- interpreter.execfile("C:\\Python27\\programs\\my_utils.py");
- PyFunction func = (PyFunction)interpreter.get("adder",PyFunction.class);
-
- int a = 2010, b = 2 ;
- PyObject pyobj = func.__call__(new PyInteger(a), new PyInteger(b));
- System.out.println("anwser = " + pyobj.toString());
-
-
- }//main
- }
得到的结果是:anwser = 2012
3.使用java直接执行python脚本,
建立脚本inputpy
- #open files
-
- print 'hello'
- number=[3,5,2,0,6]
- print number
- number.sort()
- print number
- number.append(0)
- print number
- print number.count(0)
- print number.index(5)
建立java类,调用这个脚本:
- import javax.script.*;
-
- import org.python.core.PyFunction;
- import org.python.core.PyInteger;
- import org.python.core.PyObject;
- import org.python.util.PythonInterpreter;
-
- import java.io.*;
- import static java.lang.System.*;
- public class FirstJavaScript
- {
- public static void main(String args[])
- {
-
- PythonInterpreter interpreter = new PythonInterpreter();
- interpreter.execfile("C:\\Python27\\programs\\input.py");
- }//main
- }
得到的结果是:
- hello
- [3, 5, 2, 0, 6]
- [0, 2, 3, 5, 6]
- [0, 2, 3, 5, 6, 0]
- 2
- 3
