我想从 java 程序运行 pict.exe

Question

PICT 生成测试用例和测试配置。 https://github.com/microsoft/pict

我想通过 java 程序运行可执行文件 pict.exe。我尝试使用 Runtime.getRuntime.exec()，它运行没有任何错误，但没有生成输出文件。

package com.test.CommandLine;

public class CommandLineTest {

    public static void main(String[] args) {
        String execPath = "resources\pict.exe";
        String param = "resources\CarOrderApp.txt > resources\CarOrderApp.xls";

        runPict(execPath, param);
    }

    public static void runPict(String execPath, String param) {
        try {
            Process process = Runtime.getRuntime().exec(execPath + " " + param);
        } 
        catch (Exception e) {
            System.out.println(e.getMessage() + "\n");
            e.printStackTrace();
        }
    }
}

这是我的项目结构：

您需要使用 ProcessBuilder 来定义输出，而不是使用 cmd > 重定向运算符：

String execPath = "resources\pict.exe";
String inPath = "resources\CarOrderApp.txt";
String outPath = "resources\CarOrderApp.xls";

ProcessBuilder builder = new ProcessBuilder(execPath, inPath);
builder.redirectOutput(new File(outPath));
Process p = builder.start();
p.waitFor();
