Question

我正在尝试使用所有绝对路径的params执行pdf2html。同一命令通过命令提示符正常工作，但通过java给出错误。这是我正在使用的代码片段。

String command = pdf2html5ex_file_path + 
                    " --decompose-ligature 1 --tounicode 1 \""  + 
                    _curr_pdf_file.getAbsolutePath() + 
                    "\" \"" + 
                    _input_html_file_name + 
                    "\" --dest-dir \"" + 
                    removeEnd(_input_html_folder_path,"\\") + 
                    "\" ";
String Perms = _curr_pdf_file.canRead()?"Readable":"Non-Readable";
Perms += ";"+ (_curr_pdf_file.canWrite()?"Writable":"Non-Writable");
Perms += ";"+ (_curr_pdf_file.canExecute()?"Executable":"Non-Executable");
System.out.println("Permissions : "+Perms);
System.out.println("Command: "+command);
Runtime runtime = Runtime.getRuntime();
// Execute command
Process process = runtime.exec(command);

异常消息：

Permissions : Readable;Writable;Executable

在上面的输出中，尝试打印将要执行的命令，它显示正确的文件路径为字符串，但第二行显示无法读取错误路径的文件（两个空格不存在）。

有人可以解释这里发生的事情吗？

无法执行带有多个空格作为参数的文件名的Windows命令行命令
