python寫了一個方法，windows平臺上怎么被Java服務(wù)調(diào)用呢？

最簡單的辦法，python利用pyinstaller打包成.exe程序，Java程序通過Process調(diào)用，想同時獲取.exe執(zhí)行過程中打印出的日志用ProcessBuilder

親測有效，源代碼如下

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;public class TestOutput {public static void main(String[] arguments) throws IOException, InterruptedException {System.out.println(getProcessOutput());}public static String getProcessOutput() throws IOException, InterruptedException {// 參數(shù)1 exe的絕對路徑 參數(shù)2 -i  參數(shù)3 las文件目錄  23執(zhí)行exe程序必須的參數(shù)ProcessBuilder processBuilder = new ProcessBuilder("D:\\lazConvertor.exe","-i","F:\\las_test\\");processBuilder.redirectErrorStream(true);Process process = processBuilder.start();System.out.println("start: " + process.isAlive());StringBuilder processOutput = new StringBuilder();try (BufferedReader processOutputReader = new BufferedReader(new InputStreamReader(process.getInputStream()));) {String readLine;while ((readLine = processOutputReader.readLine()) != null) {processOutput.append(readLine + System.lineSeparator());}process.waitFor();} catch (IOException e) {System.out.println(e.getMessage());} catch (InterruptedException e) {System.out.println(e.getMessage());} finally {if (process != null) {process.destroy();}}return processOutput.toString().trim();}
}

總結(jié)
