java中执行python脚本工具类，需要jython.jar

import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;</div>
import org.python.core.PyObject;
import org.python.util.PythonInterpreter;</div>
<div>public final class JythonUtil {

private JythonUtil(){}

/**
 * 执行某个.py文件
 * @param filePath
 * @throws IOException
 */
public static void pythonExecute(String filePath) throws IOException{
PythonInterpreter pin = new PythonInterpreter();
InputStream is = new FileInputStream(filePath);
pin.execfile(is);
is.close();
}

/**
 * 获取python程序的变量值
 * @param filePath
 * @param ponames
 * @return
 * @throws IOException
 */
public static List<PyObject> transP2JData(String filePath, String...ponames) throws IOException{
PythonInterpreter pin = new PythonInterpreter();
InputStream is = new FileInputStream(filePath);
pin.execfile(is);
is.close();
List<PyObject> pos = new ArrayList<>();
for (String poname : ponames) {
PyObject po = pin.get(poname);
pos.add(po);
}
return pos;
}

/**
 * 将参数赋给python程序执行
 * @param filePath
 * @param pomaps
 * @throws IOException
 */
public static void transJ2PData(String filePath, Map<String, Object> pomaps) throws IOException {
PythonInterpreter pin = new PythonInterpreter();
InputStream is = new FileInputStream(filePath);
for (String pomapkey : pomaps.keySet()) {
pin.set(pomapkey, pomaps.get(pomapkey));
}
pin.execfile(is);
is.close();
}

/**
 * 将参数赋给python程序执行,并获取python中的变量值
 * @param filePath
 * @param pomaps
 * @param ponames
 * @return
 * @throws IOException
 */
public static List<PyObject> transJ2PData(String filePath, Map<String, Object> pomaps, String...ponames) throws IOException {
PythonInterpreter pin = new PythonInterpreter();
InputStream is = new FileInputStream(filePath);
for (String pomapkey : pomaps.keySet()) {
pin.set(pomapkey, pomaps.get(pomapkey));
}
pin.execfile(is);
is.close();
List<PyObject> pos = new ArrayList<>();
for (String poname : ponames) {
PyObject po = pin.get(poname);
pos.add(po);
}
return pos;
}
<div>}
