java直接调用python脚本的例子
复制代码 代码如下:
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class Main {
public static void main(String[] args) {
try {
System.out.println(\”start\”);
Process pr = Runtime.getRuntime().exec(\”python test.py\”);
BufferedReader in = new BufferedReader(new InputStreamReader(
pr.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
System.out.println(line);
}
in.close();
pr.waitFor();
System.out.println(\”end\”);
} catch (Exception e) {
e.printStackTrace();
}
}
}
如果在eclipse中直接运行报如下错误：
java.io.IOException: Cannot run program \”python\”: CreateProcess error=2
则配置Run Configuration中的Enviroment，增加PATH变量，见下图：
