Question

我创建了一个Java gui，它将用户的值发送到python文件进行处理，然后将python文件的输出显示到java gui上。这在eclipse上运行良好，但是当我将其导出到jar文件时，不会显示输出。我已经看到了许多其他类似问题，但是它们并没有提供对我有帮助的解决方案。

这是我将python脚本连接到Java的方式。

public void connection(String name)
    {
        ProcessBuilder pb= new ProcessBuilder("python","recomold.py","--movie_name",name);
         ///System.out.println("running file");
         Process process = null;
        try {
            process = pb.start();
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
         int err = 0;
        try {
            err = process.waitFor();
        } catch (InterruptedException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        // System.out.println("any errors?"+(err==0 ? "no" : "yes"));
        /* try {
            System.out.println("python output "+ output(process.getInputStream()));
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }*/
         try {
            matches.setText(output(process.getInputStream()));
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

    private String output(InputStream inputStream) throws IOException {
        StringBuilder sb = new StringBuilder();
        BufferedReader br = null;
        try{
            br= new BufferedReader(new InputStreamReader(inputStream));
            String line = null;
            while((line=br.readLine())!=null)
            {
                sb.append(line+"\n");
                //descp.setText("<html><br/><html>");
                //sb.append("\n");
            }
        }
        finally
        {                   
                br.close();                 
        }
        return sb.toString();
    }

运行时Python输出未显示在jar文件中
