jxl导出excel的具体例子
作为一个刚工作不久的开发者来说，积累自己的代码很有必要。下面是总结jxl的导出excel文件的一个实例：
1、首先需要导入jxl.jar到自己的项目中
try {
//期刊
List
//业务员
List
//结算日期
String date = getPara("date", time.getTimeBymonth());
//获取选中的期刊id
Integer pid = getParaToInt("pid", plist.get(0).getInt("pub_id"));
Publish pub = Publish.dao.findById(pid);
//获取业务员id
Integer uid = getParaToInt("uid", ulist.get(0).getInt("user_id"));
User user = User.dao.findById(uid);
String[] riqi = date.split("-");//riqi[0] 年份
List
Issue iss = Issue.dao.findFirst("select * from issue where iss_name=" + riqi[1] + " and pub_id=" + pid);
List
+ iss.getInt("iss_id") + " and a.pub_id=" + pid + " and a.acc_year='" + riqi[0] + "'");
List
+ " FROM accounts a LEFT JOIN customers c ON a.cus_id=c.cus_id " + "WHERE a.user_id=" + uid + " and a.iss_id="
+ iss.getInt("iss_id") + " and a.pub_id=" + pid + " and a.acc_year='" + riqi[0] + "' GROUP BY a.cus_id");
//打开文件
WritableWorkbook book = Workbook.createWorkbook(new File(PathKit.getWebRootPath() + "/temp/" + riqi[0] + "年"
+ user.getStr("user_xingming") + "《"+ pub.getStr("pub_name")+"》" + iss.getStr("iss_name") + "期销售结算表.xls"));
//生成名为“第一页”的工作表，参数0表示这是第一页
WritableSheet sheetOne = book.createSheet("结算表", 0);
//在Label对象的构造子中指名单元格位置是第一列第一行(0,0)
/**
* 定义单元格样式
*/
WritableFont wf_title = new WritableFont(WritableFont.ARIAL, 11,
WritableFont.NO_BOLD, false, UnderlineStyle.NO_UNDERLINE,
jxl.format.Colour.BLACK); // 定义格式 字体 下划线 斜体 粗体 颜色
WritableCellFormat wcf_title = new WritableCellFormat(wf_title); // 单元格定义
wcf_title.setBackground(jxl.format.Colour.WHITE); // 设置单元格的背景颜色
wcf_title.setAlignment(jxl.format.Alignment.CENTRE); // 设置对齐方式
wcf_title.setBorder(jxl.format.Border.ALL, jxl.format.BorderLineStyle.THIN,jxl.format.Colour.BLACK); //设置边框
//以及单元格内容为test
Label Title = new Label(0, 0, "" + riqi[0] + "年" + user.getStr("user_xingming") +"《"+ pub.getStr("pub_name")+"》" + iss.getStr("iss_name")
+ "期销售结算表",wcf_title);//第一行
sheetOne.setColumnView(sheetOne.getColumns(), 20); // 设置列的宽度
Label title1 = new Label(0, 1, "客户");//第二行
for (int i = 0; i < elist.size(); i++) {
if(i==0){
sheetOne.setColumnView(sheetOne.getColumns()+1, 20); // 设置列的宽度
sheetOne.addCell(new Label(sheetOne.getColumns()+1, 1, elist.get(i).getStr("edi_name") + "订刊"));
}else{
sheetOne.setColumnView(sheetOne.getColumns(), 20); // 设置列的宽度
sheetOne.addCell(new Label(sheetOne.getColumns(), 1, elist.get(i).getStr("edi_name") + "订刊"));
}
sheetOne.setColumnView(sheetOne.getColumns(), 20); // 设置列的宽度
sheetOne.addCell(new Label(sheetOne.getColumns(), 1, elist.get(i).getStr("edi_name") + "赠刊"));
}
