用Java Swing编写简单的测试小工具界面（源码）


前段时间我负责在系统中添加了HBase用于管理海量数据，功能实现后自然到了性能测试阶段，性能、可靠性、稳定性，性性都不能少。

因此就有了个内部的小需求：“给测试部提供一个工具，可以向HBase写入数据，以达到测试所需的数据量”。

由于我们的系统是由Java编写，Client的代码也用的Hadoop的Java API，因此小工具的界面编写理所应当的选择了Java Swing。

之前没有用过Swing，本次完全是在网上一边翻博一边编码。

首先是成品图：

OK，我知道很丑，咱不就图个实用么……

这里可以输入Hadoop集群的IP，可以选择需要操作的表，可以清空表中的记录，还有写入耗时统计。

下面是代码，代码分为两个文件，一个是MainView负责界面展示；另一个是Worker线程，负责干活和刷新进度条与显示数据。

大家如需要可随意使用，改成自己的小工具，只要把Worker中的// TODO: 改为实际运行的程序即可。
