JExcel API使用笔记

JExcel API使用笔记 

JExcel是一个开源的支持excel的java类库，广泛利用其api来生成excel报表 

 

• 下载JExcel

        
            net.sourceforge.jexcelapi
            jxl
            2.6.12
        

• 数据写入到excel文件

从jira中查询数据，导出生成一个搜集用户体验问题的excel报表，并且简单设置表格格式。

 

 @Test
    public void testBugStatistic() throws Exception {
        List issues = myJiraClient.getIssues("issuetype = Bug AND BUG类型 = 用户体验 AND assignee in (lifei66) ORDER BY created DESC");

        WritableWorkbook workbook = Workbook.createWorkbook(new File("7Fresh移动端用户体验问题.xls"));
        WritableSheet sheet = workbook.createSheet("用户体验优化建议", 0);

        List titles = Arrays.asList("issueKey", "标题", "报告人", "创建日期", "状态", "链接");
        List labels = new ArrayList<>();
        for (int i = 0; i < titles.size(); i++) {
            for (int j = 0; j < issues.size() + 1; j++) {
                if (j == 0) {
                    WritableCellFormat titleCellFormat = new WritableCellFormat(new WritableFont(WritableFont.createFont("微软雅黑"), 14, WritableFont.BOLD, false, UnderlineStyle.NO_UNDERLINE, Colour.BLACK));
