运行时jar文件中未显示java Python输出
我创建了一个JavaGUI，它从用户那里获取值并将其发送到python文件进行处理，然后将python文件的输出显示到JavaGUI上。这在eclipse上工作得非常好，但是当我将其导出到jar文件中时，不会显示输出。我见过很多其他类似的问题，但它们并没有给出一个对我有帮助的解决方案
这就是我如何将python脚本连接到java的方法
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();
}
