创建和执行批处理文件并将输出链接到进度条 [英] Creating and executing batch file and linking the output to a progress bar

问题描述

我正在创建一个 Java swing GUI，它从用户(通过文本字段)获取很少的参数并将它们存储在一个名为 finalstring 的字符串中.这个字符串基本上是一个命令，它运行一个带有很少参数的.exe"文件.现在我想创建一个批处理文件(桌面上的start.bat)，我想在其中复制这个字符串.最后我想执行这个批处理文件.随着执行，我还想存储这个批处理文件的输出.此外，批处理文件执行某些进程，我想将其与进度条链接，这可能吗?(在批处理文件中运行的进程，要链接到 java swing 的进度条?).

I am creating a Java swing GUI, which takes few parameters from user (through text fields) and stores them in a string called finalstring. This string is basically a command, which runs an ".exe" file with few parameters. Now i want to create a batch file(start.bat on my desktop), in which i want to copy this string. Finally i want to execute this batch file. Along with the execution, i also want to store the output of this batch file. Also, the batch file executes certain process, which i want to link with progress bar, is this possible?(process running in batch file, to be linked to java swing's progress bar?).

我使用python和tkinter作为GUI做了以上所有事情，但是在批处理文件的输出存储期间，我的tkinter gui曾经挂起(没有响应)，所以我切换到java swings GUI.我搜索了大部分在线线程，但我的脑海中没有任何内容(还创建了几个 Java 程序，但没有创建批处理文件)，所以我需要帮助，感谢您为浏览此线程所做的努力.

I did all above things using python and tkinter as GUI, but during the storage of output of batch file, my tkinter gui used to hang(not responding), so i am switching to java swings GUI. I searched most of the online threads, but nothing is going in my head(created few java programs also, but the batch file is not being created), so i want help, i appreciate your effort to go through this thread.

推荐答案

您可以使用 ProcessBuilder，如图此处>.您可以将组合输出流中的 append() 行添加到 JTextArea，如下所示 这里.

You can execute your batch using ProcessBuilder, as shown here. You can append() lines from the combined output stream to a JTextArea, as shown here.

我不确定您是否可以在 JProgressBar 不知道更多关于进程的粒度.

I'm not sure you can usefully display progress in a JProgressBar without knowing more about the granularity of the process.
