到此处项目就可以运行了,点击导出后,就可以再文件中找到导出的文件了
a、填充数字
b、填充格式化的数字
c、填充日期
d、填充文本
e、填充boolean值
java使用freemarker作为模板导出Excel表格
1:首先新建一个excel表格自己弄好格式如下图
2:把excel 表格另存为xml格式文件如下图
3:这个时候的文件就是xml 格式的文件了,在myeclipse里面项目工程里面新建一个文件后缀为.ftl 然后把弄好的xml文件内容直接复制粘贴到.fl文件里面
如图
4:好了,现在我们直接java 后台action 类代码如下
/** * 导出订单表 * @throws Exception */ public void exportOrder() throws Exception{ HttpServletRequest request = ServletActionContext.getRequest(); HttpServletResponse response = ServletActionContext.getResponse(); Map<String, Object> map = new HashMap<String, Object>(); BookOrder bookOrder = new BookOrder(); bookOrder.setOrderNo(params.getOrderNo()); bookOrder.setName(params.getName()); bookOrder.setPhone(params.getPhone()); if(params.getCompany() !=null && params.getCompany().getId() !=null){ bookOrder.setCompany(companyService.load(params.getCompany().getId())); } bookOrder.setOrderStatus(params.getOrderStatus()); bookOrder.setDistType(params.getDistType()); bookOrder.setFoodType(params.getFoodType()); bookOrder.setStartTime(params.getStartTime()); bookOrder.setEndTime(params.getEndTime()); bookOrder.setRefundStatus(params.getRefundStatus()); bookOrder.setReminder(params.getReminder()); if(params.getStall() !=null && params.getStall().getId() !=null){ bookOrder.setStall(stallService.load(params.getStall().getId())); } List<BookOrder> bookOrderList = (List<BookOrder>)targetService.loadList(bookOrder); map.put("bookOrderList", bookOrderList); File file = null; InputStream inputStream = null; ServletOutputStream out = null; try { request.setCharacterEncoding("UTF-8"); file = ExcelUtils.createExcel(map, "myExcel","order.ftl");//调用创建excel帮助类 inputStream = new FileInputStream(file); response.setCharacterEncoding("utf-8"); response.setContentType("application/msexcel"); response.setHeader("content-disposition", "attachment;filename="+ URLEncoder.encode("订单统计" + ".xls", "UTF-8")); out = response.getOutputStream(); byte[] buffer = new byte[512]; // 缓冲区 int bytesToRead = -1; // 通过循环将读入的Excel文件的内容输出到浏览器中 while ((bytesToRead = inputStream.read(buffer)) != -1) { out.write(buffer, 0, bytesToRead); } out.flush(); } catch (Exception e) { e.printStackTrace(); } finally { if (inputStream != null) inputStream.close(); if (out != null) out.close(); if (file != null) file.delete(); // 删除临时文件 } }
5:下面这个是Utils 公共方法如下
package com.funcanteen.business.action.pay.util; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.io.OutputStreamWriter; import java.io.Writer; import java.util.HashMap; import java.util.Map; import org.apache.struts2.ServletActionContext; import freemarker.template.Configuration; import freemarker.template.Template; /** * 导出excel Utils * @author Administrator * */ public class ExcelUtils { private static Configuration configuration =null; private static Map<String, Template> allTemplates =null; private static String realPath = ServletActionContext.getServletContext().getRealPath("/"); /*static{ configuration = new Configuration(); configuration.setDefaultEncoding("UTF-8"); try { configuration.setDirectoryForTemplateLoading(new File(realPath+"WEB-INF/mailtemplate")); allTemplates = new HashMap<String, Template>(); allTemplates.put("myExcel", configuration.getTemplate("order.ftl")); } catch (Exception e) { e.printStackTrace(); throw new RuntimeException(e); } }*/ public ExcelUtils(){ throw new AssertionError(); } /** * 创建excel * @param dataMap * @param type * @return */ public static File createExcel(Map<?, ?> dataMap, String type,String valueName){ try { configuration = new Configuration(); configuration.setDefaultEncoding("UTF-8"); configuration.setDirectoryForTemplateLoading(new File(realPath+"WEB-INF/mailtemplate")); allTemplates = new HashMap<String, Template>(); allTemplates.put(type, configuration.getTemplate(valueName)); } catch (IOException ex) { ex.printStackTrace(); throw new RuntimeException(ex); } String name = "temp" + (int) (Math.random() * 100000) + ".xls"; File file = new File(name); Template template = allTemplates.get(type); try { Writer w = new OutputStreamWriter(new FileOutputStream(file), "utf-8"); template.process(dataMap, w); w.close(); } catch (Exception e) { e.printStackTrace(); throw new RuntimeException(e); } return file; } }
6下面是ftl 模板文件
