java jython 调用_如何从Jython调用由Java类执行的Java方法？

是的，这种方式很好，但你不能在构造函数方法中运行python脚本，如果是这样，它将在你的代码中死亡递归。请参阅以下代码。你运行PythonScriptTest类，它将首先运行python脚本，然后python脚本将调用PythonScriptTest.SpawnPlayer()方法。

java代码：

package com.xxx.jython;

import org.python.core.PyFunction;

import org.python.util.PythonInterpreter;

public class PythonScriptTest {

public static void main(String[] args) {

PythonScriptTest f = new PythonScriptTest();

f.executePythonScript();

}

public PythonScriptTest(){

}

public void executePythonScript() {

PythonInterpreter interpreter = new PythonInterpreter();

interpreter.execfile("/home/XXX/XXX/util.py");

PyFunction pyFuntion = (PyFunction) interpreter.get("InGameCommand", PyFunction.class);

pyFuntion.__call__();

}

public void SpawnPlayer() {

System.out.println("Run SpawnPlayer method ##################");

}

}Python脚本，名为util.py：

import sys.path as path

# the following path is eclipse output class dir

# does not contain java class package path.

path.append("/home/XXX/XXX/Test/bin")

from com.xxx.jython import PythonScriptTest

def add(a, b):

return a + b

def InGameCommand():

myJava = PythonScriptTest()

myJava.SpawnPlayer()
