Java服务如何调用系统指令、Bat脚本记录

    public void executeBatScript(String cCommand, String cBatFileName, String cBasePath) throws Exception {
        //判断路径是否存在
        File directory = new File(cBasePath);
        if (!directory.exists()) {
            directory.mkdir();
        }
        String tBatFilePath = cBasePath + cBatFileName + ".bat"; // 批处理文件的路径和名称

        // 创建一个Writer对象来写入批处理命令
        PrintWriter writer = new PrintWriter(new FileWriter(tBatFilePath));
        writer.println(cCommand); // 在批处理文件中写入命令
        writer.close(); // 关闭Writer对象

        // 执行批处理文件
        ProcessBuilder builder = new ProcessBuilder(tBatFilePath);
        // 输出指令日志
        builder.redirectOutput(ProcessBuilder.Redirect.INHERIT);
        builder.redirectError(ProcessBuilder.Redirect.INHERIT);
        // 启动进程并后台执行批处理文件
        builder.start();

        // 删除生成的批处理文件
        File file = new File(tBatFilePath);
        if (file.delete()) {
            log.info("Batch file deleted successfully.");
        }
    }
