Java调用Python脚本工具类

Java调用Python脚本工具类

[本文出自天外归云的博客园]

在网上查了很多方法都不成功,在google上搜到一篇文章,做了一些小修改,能够处理中文输出。提取一个运行python脚本的Java工具类如下:

package com.autox.util;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;

public class RunPython {
    public static ArrayList<String> run_py(String script) {
        String s = null;
        ArrayList<String> result = new ArrayList<String>();
        ArrayList<String> error = new ArrayList<String>();
        try {
            Process p = Runtime.getRuntime().exec(script);
            BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream(), "GBK"));
            BufferedReader stdError = new BufferedReader(new InputStreamReader(p.getErrorStream()));
            while ((s = stdInput.readLine()) != null) {
                result.add(s);
            }
            while ((s = stdError.readLine()) != null) {
                error.add(s);
            }
            if (error != null) {
                System.out.println(error);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return result;
    }
}

Java中调用方法如下:

ArrayList<String> result = RunPython.run_py("python script_path args");
for (String item : result) {
    System.out.println(item);
}

其中script_path需替换为Python脚本路径,args替换为向脚本传递的参数。
