方法一：通过RunTime.getRuntime().exec(shellScript)
//方式1 不带参数 String classpath = Thread.currentThread().getContextClassLoader().getResource("").getPath(); String shellScript = null; if (System.getProperties().getProperty("os.name").toLowerCase().indexOf("windows") != -1){ shellScript = String.format("python template.py", classpath.substring(1)); }else { shellScript = String.format("python3 template.py", classpath.substring(1),classpath); } Runtime rt = Runtime.getRuntime(); //方式2 带参数 String command = "D:\\calculator_simple.py"; String num1 = "1"; String num2 = "2"; String[] cmdArr = new String[] {exe， command， num1， num2}; Process process = Runtime.getRuntime().exec(cmdArr); InputStream is = process.getInputStream(); DataInputStream dis = new DataInputStream(is); String str = dis.readLine(); process.waitFor(); System.out.println(str); //此处输出3 #calculator_simple.py脚本 # coding=utf-8 from sys import argv num1 = argv[1] num2 = argv[2] sum = int(num1) + int(num2) print sum
方法2：通过Jython调用，这种方式不太推荐，记得调用selenium的库会报No module found，可是明明引用了，而且java社区不太喜欢这种强耦合的方式调用Python，所以官网也不怎么更新了，在微服务架构大行其道的今天，这种程序间嵌套调用的方式将会逐渐被淘汰
String python = "D:\\simple_python.py"; PythonInterpreter interp = new PythonInterpreter(); interp.execfile(python);
//方式1 不带参数
String command = "D:\\calculator_simple.py";
String num1 = "1";
String num2 = "2";
String[] cmdArr = new String[] {exe， command， num1， num2};
Process process = Runtime.getRuntime().exec(cmdArr);
InputStream is = process.getInputStream();
DataInputStream dis = new DataInputStream(is);
String str = dis.readLine();
process.waitFor();
System.out.println(str);标签：col word span nbsp bsp text comm current keyword
