projects/jython/下载jython包,把其中的jython.jar添加到工程目录
1.在java类中直接执行python语句
view plain
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
view plain
def adder(a, b):
return a + b
然后建立一个java类,用来测试,
java类代码 FirstJavaScript:
view plain
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
view plain
#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:
view plain
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:
view plain
hello
[3, 5, 2, 0, 6]
[0, 2, 3, 5, 6]
[0, 2, 3, 5, 6, 0]
2
