Java 从数据库中查找信息导入Excel表格中 / 憋错料

前端js

function Excel (){
      //ajax请求
      $.ajax({
           url : "outPutAboutShopInfo",
           type : "post",
           dataType : "json",
           data:{
               "basicShop.shopId" : shopId,
               "basicShop.shopMemo" : stringType           //不方便增加字段所以使用门店的一个“备注”字段来接收‘类型‘
           },
           success : function(data) {
               window.location.href = data.communal.data;
           }
      });

}

后端 Java

该方法是将数据插入excel中，将excel保存到服务器中，然后访问服务器下载文件，方法不怎么好

需要导入的jar包

第一：获得数据的方法

　　使用存储过程获得数据

　　举例：

// 这个存储过程的核心就是一条简单的sql语句DELIMITER $$

DROP PROCEDURE IF EXISTS `pahung82`.`ht_out_put_mem_phone`$$

CREATE DEFINER=`root`@`%` PROCEDURE `ht_out_put_mem_phone`(
in shopId varchar(40)  -- 门店Id
)
BEGIN
    SELECT VIP_NAME ,VIP_TELEPHONE from mem_vip  where SHOP_ID = shopId;
END$$

DELIMITER ;

　　结果类似如下：

第二：调用存储过程，将数据写入excel表格

　　1.调用存储过程　

Session session = null;
Connection conn = null;
CallableStatement cs = null;
ResultSet rs = null;
// 存储过程 条件 门店Id
String shopId = basicShop.getShopId();

try {
    　　session = this.hibernateTemplate.getSessionFactory().openSession();
    　　session.beginTransaction();
    　　conn = session.connection();　　　　// 存储过程调用
    　　cs = conn.prepareCall("{call ht_out_put_mem_phone(?)}");
    　　cs.setString(1, shopId);// 填充参数

    　　boolean hadResults = false;　　　　// 运行存储过程
   　　 hadResults = cs.execute();
    　　int index = 0, no = 0;

   　　 while (hadResults) {
   　　 　　rs = (ResultSet) cs.getResultSet();
   　　 　　if (index == 0) {
    　　　　　　while (rs.next()) {
   　　 　　　　　　no++;
   　　　　 　　　　row = sheet.createRow((int) no);
  　　  　　　　　　// 创建单元格，设置值　　　　　　　　　　// 这里就是循环结果集的值
    　　　　　　}
    　　　　}
    　　　　hadResults = cs.getMoreResults(); // 检查是否存在更多结果集
    　　　　index++;
    　　}

    } catch (Exception e) {
         e.printStackTrace();
    } finally {
         rs.close();
         cs.close();
         session.clear();
         conn.close();
         session.close();
    }

　　2.将数据写入excel表格

    Session session = null;
    Connection conn = null;
    CallableStatement cs = null;
    ResultSet rs = null;
    // 存储过程 条件 门店Id
    String shopId = basicShop.getShopId();

    // 1.创建一个workbook，对应一个Excel文件
    HSSFWorkbook wb = new HSSFWorkbook();

    // 2.在workbook中添加一个sheet，对应Excel中的一个sheet
    HSSFSheet sheet = wb.createSheet("手机号");
    // 3.在sheet中添加表头第0行，老版本poi对excel行数列数有限制short
    HSSFRow row = sheet.createRow((int) 0);
    // 4.创建单元格，设置值表头，设置表头居中
    HSSFCellStyle style = wb.createCellStyle();
    // 居中格式
    style.setAlignment(HSSFCellStyle.ALIGN_CENTER);

    // 设置表头
    HSSFCell cell = row.createCell(0);
    cell.setCellValue("姓名");
    cell.setCellStyle(style);

    cell = row.createCell(1);
    cell.setCellValue("手机号");
    cell.setCellStyle(style);

    try {
        session = this.hibernateTemplate.getSessionFactory().openSession();
        session.beginTransaction();
        conn = session.connection();
        cs = conn.prepareCall("{call ht_out_put_mem_phone(?)}");
        cs.setString(1, shopId);

        boolean hadResults = false;
        hadResults = cs.execute();
        int index = 0, no = 0;

        while (hadResults) {
            rs = (ResultSet) cs.getResultSet();
            if (index == 0) {
                while (rs.next()) {
                    no++;
                    row = sheet.createRow((int) no);
                    // 创建单元格，设置值
                    row.createCell(0).setCellValue(rs.getString(1));
                    row.createCell(1).setCellValue(rs.getString(2));
                }
            }
            hadResults = cs.getMoreResults(); // 检查是否存在更多结果集
            index++;
        }

    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        rs.close();
        cs.close();
        session.clear();
        conn.close();
        session.close();
    }

　　注意：当你要插入对个sheet时则只需再来一遍 HSSFSheet sheet_qq = wb.createSheet("QQ号"); 后面即重复

　　3.保存文件

FileOutputStream out = new FileOutputStream(request.getSession().getServletContext().getRealPath("")  + "/" + "xxx.xls");
//服务器的绝对路径  request.getSession().getServletContext().getRealPath("")
// 例如：D:\Tomcat\apache-tomcat-8.0.37\me-webapps\Test
// Test是项目名
wb.write(out);
out.close();

　　4.访问下载

HttpServletRequest request = ServletActionContext.getRequest();
// request.getRequestURL() 是StringBuffer类型，所以要转换一下
String url = request.getRequestURL().toString();
//文件路径地址  request.getRequestURL() + "xxx.xls";

文件路径地址 url =  request.getRequestURL() + "xxx.xls";只需要将路径地址传给js,success 函数中使用    window.location.href = url ; 可得到下载框

附上一个老长的代码，仅空参考

public Communal outPutAboutShopInfo(BasicShop basicShop) throws Exception {
        //存储escel文件名
        String excel_shop_name = "shop_info.xls";

        HttpServletResponse response = ServletActionContext.getResponse();

        if(null != basicShop.getShopMemo() && !"".equals(basicShop.getShopMemo())){
            out_type = basicShop.getShopMemo().toString().split(",");
        }
        Session session = null;
        Connection conn = null;
        CallableStatement cs = null;
        ResultSet rs = null;
        // 存储过程 条件 门店Id
        String shopId = basicShop.getShopId();

        // 1.创建一个workbook，对应一个Excel文件

        for(int i=0;i<out_type.length;i++) {

                HSSFRow row = sheet.createRow((int) 0);
