Excel Operation

在日常工作中， 常常需要收集统计一些数据， 然后整理到excel， 这种重复性的操作可以自己写个工具来实现。 采用HtmlUnitDriver 访问页面， 抓取数据， 再把数据列表通过调用POI放到excel。 这里先把操作excel 操作部分抽取出来， 拿到数据后， 可以直接调用该类实现存取操作。

上面已经默认对excel 风格做了初始化， 可以直接调用做保存操作：

    String []columns=new String[]{"Backend User Story","Test Case Key","User Stories","Site","Priority","Automation Keyword"};
    ExcelOperation excelOperation = new ExcelOperation(columns);
    public void saveToExcel(String savePath,List<Task> tasks){
        Hyperlink link = excelOperation.getCreateHelper().createHyperlink(Hyperlink.LINK_URL);
        int i=1;
         for(Task task:tasks){
             String []dataColumns=new String[]{task.getMainKeyword(),task.getTestCaseKey(),task.getUserStories(), task.getSite(),task.getPriority(),task.getAutomationStatus()};
             link.setAddress(String.format(testCaseURL, task.getTestCaseId()));
             excelOperation.createDataRow(i, dataColumns);
             excelOperation.setHylinkForCell(i, 1, link);
             i++;
            }
         excelOperation.saveToExcel(savePath);
    }
