在客户端/服务器应用程序中刷新JTable [英] Refreshing a JTable in a client/server application

问题描述

我开发了一个Java客户端/服务器应用程序，通过Spring RMI进行通信，该客户端是一个摆动式Jframe，它如何在顶部包含一个命令按钮(添加，更新，删除)，在中间包含一个JTable，在底部包含一个，一种形式.

I developed a Java client/server application, communicating via Spring RMI, the Client is symply a swing Jframe how containing at the top a command buttons(add, update, delete), in the middle a JTable, and at the bottom, a form.

通过使用iBatis巫婆与Apache Derby数据库进行通信，服务器端仅包含一个Dao层.

the server side contains simply a Dao layer by using iBatis witch communicates with an Apache Derby database.

因此该应用程序可以很好地工作，但是发现了两个问题:

So the application works greatly, but two problems are found :

1)当用户A从JTable添加/更新/删除行时，其他用户直到单击按钮刷新JTable中的数据才能看到更改，我想此更改必须自动完成.

1) when the user A adds/updates/deletes a row from a JTable, the others can't see the changes until clicking a button to refresh the data in the JTable, I wanna that this changes must be done automatically.

2)当用户A要更新JTable中的一行，而用户B要更改同一行时，完成后，程序始终保留最后保存的数据.

2) when the user A wants to update a row in the JTable, and the user B wants to changes the same row, when done, always teh programme keeps the last data saved.

有人可以提供有效的代码吗?或网站的链接，教程....

can some one give a working code ? or a link to a website, tutorial ....

推荐答案

1)当用户A从JTable添加/更新/删除行时，其他用户直到单击按钮刷新数据后才能看到更改.在JTable中，我想必须自动完成此更改.

1) when the user A adds/updates/deletes a row from a JTable, the others can't see the changes until clicking a button to refresh the data in the JTable, I wanna that this changes must be done automatically.

将TableModelListener添加到TableModel.每当数据更改时，您都会收到一个事件，以便您可以立即更新服务器.

Add a TableModelListener to the TableModel. You will recieve an event whenever data is changed so you can update the server right away.
