java : Not able to open finder window having space in path

Question

我想通过单击按钮打开查找器窗口并突出显示 javafx 中的特定文件，但查找器窗口未打开名称中包含空格的文件夹。相同的代码片段是:-

@FXML
    public void openFolder(ActionEvent event) {
        try {
            String upperCaseOperatingSystem=MCOBillingAppUtils.getOSName();
            String path=lblPath.getText();
            if(upperCaseOperatingSystem.contains("WINDOW")){
                Runtime.getRuntime().exec("explorer.exe /select,"+path);
            }else if(upperCaseOperatingSystem.contains("MAC")){
                Runtime.getRuntime().exec("open -R "+path);
            }
        } catch (IOException e) {
            e.printStackTrace();
            DialogMessageClass.infoBox("Something went Wrong. Please try again sometimes.", "Error");
        }catch(Exception e){
            e.printStackTrace();
            DialogMessageClass.infoBox("Something went Wrong. Please try again sometimes.", "Error");
        }
    }

路径是:/ME/开发文件夹/Short_Closed/abc.pdf

尝试的路径值是:-/ME/开发文件夹/Short_Closed/abc.pdf

/ME/Development\Folder/Short_Closed/abc.pdf(反斜杠加空格)

Answer 1

对于 Mac(也可能是 Windows)，请使用较长的形式 exec :

// note no leading forward slash
String file = "ME/Development Folder/Short_Closed/abc.pdf"
File workingDir = new File("/");
String[] cmd = new String[]{"open", "-R", file};

Runtime.getRuntime().exec(cmd, null, workingDir);

您可以按照您需要的任何方式分解要打开的工作目录和文件。例如

// Note leading forward slash:
File file = new File("/ME/Development Folder/Short_Closed/abc.pdf") ;
File workingDir = file.getParentFile();
String filename = file.getName();

String[] cmd = new String[] {"open", "-R", filename} ;
Runtime.getRuntime().exec(cmd, null, workingDir);

也可以
