一、自定义视图-Excel视图

1、Maven依赖 引入POI

        <dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>3.11</version></dependency>

2、自定义视图解析器

importjava.io.OutputStream;importjava.util.List;importjava.util.Map;importjavax.servlet.http.HttpServletRequest;importjavax.servlet.http.HttpServletResponse;importorg.apache.poi.hssf.usermodel.HSSFCellStyle;importorg.apache.poi.hssf.usermodel.HSSFDataFormat;importorg.apache.poi.hssf.usermodel.HSSFRow;importorg.apache.poi.hssf.usermodel.HSSFSheet;importorg.apache.poi.hssf.usermodel.HSSFWorkbook;importorg.springframework.web.servlet.view.document.AbstractExcelView;importcom.cn21.calendar.spider.test.User;public class ViewExcel extendsAbstractExcelView {@SuppressWarnings("unchecked")@Overrideprotected void buildExcelDocument(Map<String, Object>model, HSSFWorkbook workbook, HttpServletRequest request,HttpServletResponse response)throwsException {String fileName= "用户列表excel.xls";  response.setCharacterEncoding("UTF-8");  response.setContentType("application/ms-excel");  response.setHeader("Content-Disposition", "inline; filename="+new String(fileName.getBytes(),"iso8859-1"));  OutputStream outputStream=response.getOutputStream();List<User> userList = (List<User>) model.get("userList");//产生Excel表头HSSFSheet sheet = workbook.createSheet("基本信息");HSSFRow header= sheet.createRow(0);//产生标题列header.createCell(0).setCellValue("ID");header.createCell(1).setCellValue("名字");header.createCell(2).setCellValue("邮箱");header.createCell(3).setCellValue("密码");HSSFCellStyle cellStyle=workbook.createCellStyle();cellStyle.setDataFormat(HSSFDataFormat.getBuiltinFormat("mm/dd/yyyy"));int rowNumber = 1;for(User user : userList) {HSSFRow row= sheet.createRow(rowNumber++);//产生标题列row.createCell(0).setCellValue(user.getId());row.createCell(1).setCellValue(user.getName());row.createCell(2).setCellValue(user.getEmail());row.createCell(3).setCellValue(user.getPassword());}workbook.write(outputStream);outputStream.flush();outputStream.close();}
}

3、视图映射配置dispather-servlet.xml

　　<!-- 通过order属性来定义视图解析器的优先级，order的值越小优先级越低 --><beanclass="org.springframework.web.servlet.view.BeanNameViewResolver"><propertyname="order"value="0"></property></bean>

四、控制器代码示例

    @RequestMapping(value = "excel")publicModelAndView viewExcel() {Map<String, Object> model = new HashMap<>();model.put("userList", getStudents());return new ModelAndView(newViewExcel(), model);}private List<User>getStudents() {List<User> userList = new ArrayList<>();User user= new User("1", "Tome", "Tom@qq.com", "123456");userList.add(user);returnuserList;}

五、测试结果

二、PDF视图

1、Maven依赖包引入

        <dependency><groupId>com.itextpdf</groupId><artifactId>itext-asian</artifactId><version>5.1.0</version></dependency><dependency>  <groupId>com.lowagie</groupId>  <artifactId>itext</artifactId>  <version>2.1.7</version>  </dependency>  

2、自定义视图解析器

importjava.util.List;importjava.util.Map;importjavax.servlet.http.HttpServletRequest;importjavax.servlet.http.HttpServletResponse;importorg.springframework.web.servlet.view.document.AbstractPdfView;importcom.cn21.calendar.spider.test.User;importcom.lowagie.text.Document;importcom.lowagie.text.Paragraph;importcom.lowagie.text.pdf.BaseFont;importcom.lowagie.text.pdf.PdfWriter;public class ViewPDF extendsAbstractPdfView {@SuppressWarnings("unchecked")@Overrideprotected void buildPdfDocument(Map<String, Object>model, Document document, PdfWriter writer,HttpServletRequest request, HttpServletResponse response)throwsException {String fileName= "用户信息.pdf"; //设置response方式,使执行此controller时候自动出现下载页面,而非直接使用excel打开response.setCharacterEncoding("UTF-8");response.setContentType("application/octet-stream");response.setHeader("Content-Disposition","attachment; filename=" + new String(fileName.getBytes(), "iso8859-1"));List<User> userList = (List<User>) model.get("userList");BaseFont bfChinese= BaseFont.createFont("C://Windows//Fonts//simfang.ttf", BaseFont.IDENTITY_H,BaseFont.NOT_EMBEDDED);com.lowagie.text.Font FontChinese= new com.lowagie.text.Font(bfChinese, 12, com.lowagie.text.Font.NORMAL);for (int i = 0; i < userList.size(); i++) {User user=userList.get(i);String value= "ID: " + user.getId() + "姓名: " + user.getName() + ",邮箱: " + user.getEmail() + ",密码: "+user.getPassword();document.add(newParagraph(value, FontChinese));}}
}

3、视图映射配置dispather-servlet.xml

    <!--通过order属性来定义视图解析器的优先级，order的值越小优先级越低--><beanclass="org.springframework.web.servlet.view.BeanNameViewResolver"><propertyname="order"value="0"></property></bean>

4、控制器代码示例

    @RequestMapping("pdf")publicModelAndView viewPDF(){  Map<String, Object> model = new HashMap<>();model.put("userList", getStudents());return new ModelAndView(newViewPDF(), model);  }private List<User>getStudents() {List<User> userList = new ArrayList<>();User user= new User("1", "Tome", "Tom@qq.com", "123456");userList.add(user);returnuserList;}
