Java 從數據庫中查找信息導入Excel表格中

多結果 tput session false 狀態 結果 mmu call excel表格 
前端js
function Excel (){ //ajax請求 $.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門店的一個“備註”字段來接收‘類型‘ }, success :function(data) { window.location.href = data.communal.data; } }); }
後端 Java
該方法是將數據插入excel中，將excel保存到服務器中，然後訪問服務器下載文件，方法不怎麽好
需要導入的jar包
第一：獲得數據的方法
使用存儲過程獲得數據
舉例：
// 這個存儲過程的核心就是一條簡單的sql語句
DELIMITER $$ DROP PROCEDURE IF EXISTS `pahung82`.`ht_out_put_mem_phone`$$CREATE DEFINER=`root`@`%` PROCEDURE `ht_out_put_mem_phone`( in shopId varchar(40) -- 門店Id ) BEGIN SELECT VIP_NAME ,VIP_TELEPHONE from mem_vip where SHOP_ID = shopId; END$$ DELIMITER ;
結果類似如下：
第二：調用存儲過程，將數據寫入excel表格
1.調用存儲過程
Session session = null; Connection conn = null; CallableStatement cs= null; ResultSet rs = null; // 存儲過程 條件 門店Id String shopId = basicShop.getShopId(); try { session = this.hibernateTemplate.getSessionFactory().openSession(); session.beginTransaction(); conn = session.connection();
// 存儲過程調用 cs = conn.prepareCall("{call ht_out_put_mem_phone(?)}"); cs.setString(1, shopId);// 填充參數 boolean hadResults = false;
// 運行存儲過程 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); // 創建單元格，設置值
// 這裏就是循環結果集的值
} } hadResults = cs.getMoreResults(); // 檢查是否存在更多結果集 index++; } } catch (Exception e) { e.printStackTrace(); } finally { rs.close(); cs.close(); session.clear(); conn.close(); session.close(); }
2.將數據寫入excel表格
Session session = null; Connection conn = null; CallableStatement cs = null; ResultSet rs = null; // 存儲過程 條件 門店Id String shopId = basicShop.getShopId(); // 1.創建一個workbook，對應一個Excel文件 HSSFWorkbook wb = new HSSFWorkbook(); // 2.在workbook中添加一個sheet，對應Excel中的一個sheet HSSFSheet sheet = wb.createSheet("手機號"); // 3.在sheet中添加表頭第0行，老版本poi對excel行數列數有限制short HSSFRow row = sheet.createRow((int) 0); // 4.創建單元格，設置值表頭，設置表頭居中 HSSFCellStyle style = wb.createCellStyle(); // 居中格式 style.setAlignment(HSSFCellStyle.ALIGN_CENTER); // 設置表頭 HSSFCell cell = row.createCell(0); cell.setCellValue("姓名"); cell.setCellStyle(style); cell = row.createCell(1); cell.setCellValue("手機號"); 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); // 創建單元格，設置值 row.createCell(0).setCellValue(rs.getString(1)); row.createCell(1).setCellValue(rs.getString(2)); } } hadResults = cs.getMoreResults(); // 檢查是否存在更多結果集 index++; } } catch (Exception e) { e.printStackTrace(); } finally { rs.close(); cs.close(); session.clear(); conn.close(); session.close(); }
註意：當你要插入對個sheet時 則只需再來一遍 HSSFSheet sheet_qq = wb.createSheet("QQ號"); 後面即重復
3.保存文件
FileOutputStream out = new FileOutputStream(request.getSession().getServletContext().getRealPath("") + "/" + "xxx.xls"); //服務器的絕對路徑 request.getSession().getServletContext().getRealPath("") // 例如：D:\Tomcat\apache-tomcat-8.0.37\me-webapps\Test // Test是項目名 wb.write(out); out.close();
4.訪問下載
HttpServletRequest request = ServletActionContext.getRequest(); // request.getRequestURL() 是StringBuffer類型，所以要轉換一下 String url = request.getRequestURL().toString(); //文件路徑地址 request.getRequestURL() + "xxx.xls";
文件路徑地址 url = request.getRequestURL() + "xxx.xls";
只需要將路徑地址傳給js,success 函數中使用 window.location.href = url ; 可得到下載框
附上一個老長的代碼，僅空參考
public Communal outPutAboutShopInfo(BasicShop basicShop) throws Exception { //存儲escel文件名 String excel_shop_name = "shop_info.xls"; HttpServletRequest request = ServletActionContext.getRequest(); HttpServletResponse response = ServletActionContext.getResponse(); Communal communal = new Communal(); String [] out_type = new String []{}; // 接收導出數據類型 （1 手機號，2 會員信息，3 會員基卡，4記次卡次數信息） 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; // 存儲過程 條件 門店Id String shopId = basicShop.getShopId(); // 1.創建一個workbook，對應一個Excel文件 HSSFWorkbook wb = new HSSFWorkbook(); for(int i=0;i<out_type.length;i++) { // 導出會員手機號碼 if ( out_type[i] .equals("1")) { System.out.println(); // 2.在workbook中添加一個sheet，對應Excel中的一個sheet HSSFSheet sheet = wb.createSheet("手機號"); // 3.在sheet中添加表頭第0行，老版本poi對excel行數列數有限制short HSSFRow row = sheet.createRow((int) 0); // 4.創建單元格，設置值表頭，設置表頭居中 HSSFCellStyle style = wb.createCellStyle(); // 居中格式 style.setAlignment(HSSFCellStyle.ALIGN_CENTER); // 設置表頭 HSSFCell cell = row.createCell(0); cell.setCellValue("姓名"); cell.setCellStyle(style); cell = row.createCell(1); cell.setCellValue("手機號"); 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); // 創建單元格，設置值 row.createCell(0).setCellValue(rs.getString(1)); row.createCell(1).setCellValue(rs.getString(2)); } } hadResults = cs.getMoreResults(); // 檢查是否存在更多結果集 index++; } } catch (Exception e) { e.printStackTrace(); } finally { rs.close(); cs.close(); session.clear(); conn.close(); session.close(); } } //導出會員信息 if (out_type[i] .equals("2")) { // 2.在workbook中添加一個sheet，對應Excel中的一個sheet HSSFSheet sheet = wb.createSheet("會員信息");
