java调用python:通过bat调用exe实现(与RunTime.getRuntime().exec()类似)

bat文件测试

echo hello world！
pause

md e:\test

工程需要的bat文件

C:\**\**\**\**为python的地址

@echo off
::set INTERVAL = 10
::timeout %INTERVAL%
::Again   

echo local_cap  
C:
cd C:\**\**\**\**
start python  chengxu\juzhentezheng.py
pause
rem 使用ping命令暂停3s，这样可以看到调用python后的结果
::ping -n 10 127.0.0.1 > nul

java调用代码


import java.io.BufferedReader;
import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;




try {
		StringBuilder sb = new StringBuilder();
		String batPath = "C:/helloworld.bat";
		Process child = Runtime.getRuntime().exec(batPath);
		InputStream in = child.getInputStream();
		BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(in));
		String line;
		while ((line = bufferedReader.readLine()) != null) {
			sb.append(line + "\n");
		}
		in.close();
		try {
			child.waitFor();
		} catch (InterruptedException e) {
			System.out.println(e);
		}
        } catch (IOException e) {
            System.out.println(e);
        }
