用Java Swing编写简单的测试小工具界面（源码）

Author：Pirate Leo

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。

Begin!

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。

MainView代码：

Worker代码：

package com.codeevoship.gui;import javax.swing.JProgressBar;import javax.swing.JTextField;public class DoWork implements Runnable {JProgressBar probar;JTextField curTxtShow;long totalNum = 0;long curNum = 0;long startTime = 0;long curTime = 0;public DoWork(String ip, long num, boolean isWriteCon, boolean isWriteArc, boolean isWriteSys, boolean isClearData, JProgressBar probar, JTextField curTxtShow) {System.out.println("IP:" + ip + ", Num:" + num);System.out.println("Write Content[" + isWriteCon + "], Write Archive[" + isWriteArc + "], Write SystemLog[" + isWriteSys + "].");startTime = 0;curNum = 0;totalNum = num;this.probar = probar;this.curTxtShow = curTxtShow;}@Overridepublic void run() {startTime = System.currentTimeMillis();// 开始工作System.out.println("Do Work Start!");StringBuilder sb = new StringBuilder();while (true) {if (curNum >= totalNum) {break;}try {// TODO: Real work hereThread.sleep(10);// 更新界面显示curNum += 1;probar.setValue((int) (curNum*100/totalNum));curTime = System.currentTimeMillis();sb.setLength(0);sb.append(curNum);sb.append('/');sb.append(totalNum);sb.append(" cost time: ");sb.append((curTime - startTime)/1000);sb.append('s');curTxtShow.setText(sb.toString());} catch (Exception e) {e.printStackTrace();}}System.out.println("Do Work End!");}}

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。
