解决java与python整合过程的问题-执行python问题报错

import org.python.util.PythonInterpreter;
 
import java.io.DataInputStream;
import java.util.Properties;
 
public class a {
    public static void main(String[] args) throws Exception{
        Properties props = new Properties();
        props.put("python.home", "D:\\jython2.7.2\\software\\Lib");
        props.put("python.console.encoding", "UTF-8");
        props.put("python.security.respectJavaAccessibility", "false");
        props.put("python.import.site", "false");
        Properties properties = System.getProperties();
        PythonInterpreter.initialize(properties, props, new String[0]);
 
        PythonInterpreter interpreter = new PythonInterpreter();
        interpreter.exec("print('hello')");
        //当python文件中使用了 import 并调用了第三方库 执行以下命令就会报错
        //interpreter.execfile("F:\\graduate\\pro\\src\\main\\java\\p1.py");
 
        fun();
    }
    //此方法解决了python文件含有import 进入第三方库的问题
    public static void fun() throws Exception{
        String exe = "python";
        String command = "F:\\graduate\\pro\\src\\main\\java\\p1.py";
        String[] cmdArr = new String[] {exe,command};
        Process process = Runtime.getRuntime().exec(cmdArr);
        DataInputStream dis = new DataInputStream(process.getInputStream());
        String str = "";
        while((str = dis.readLine()) != null)
            System.out.println(str);
    }
}
