java执行python脚本并传递参数_Java 调用Python脚本，实现带参数

public class JavaRunPython {

public static String ByJython(Map map,String filePath,String methodName) {

Properties props = new Properties();

props.put(“python.console.encoding”, “UTF-8”);

// Used to prevent: console: Failed to install ”: java.nio.charset.UnsupportedCharsetException: cp0.

props.put(“python.security.respectJavaAccessibility”, “false”);

//don’t respect java accessibility, so that we can access protected members on subclasses

props.put(“python.import.site”,”false”);

Properties preprops = System.getProperties();

PythonInterpreter.initialize(preprops, props, new String[0]);

PythonInterpreter interp= new PythonInterpreter();

// 1. Python面向函数式编程: 在Java中调用Python函数

//String pythonFunc = “D:\\javaPythonFile.py”;

// 加载python程序

interp.execfile(filePath);

for (Map.Entry mp : map.entrySet()) {

interp.set(mp.getKey(), mp.getValue());

}

// System.setProperty(“python.home”, “”);

// 调用Python程序中的函数

PyFunction pyf = interp.get(methodName, PyFunction.class);

//PyObject dddRes = pyf.__call__(Py.newString(“zhangsan”), Py.newInteger(3));

PyObject pyObj = pyf.__call__();

String str = (String) pyObj.__tojava__(String.class);

pi1.cleanup();

pi1.close();

return str;

}

}
