控制器：
Java代码
public class EExcelDownController extends AbstractController {
private ICourse_infoManage courseManage;
public void setCourseManage(ICourse_infoManage courseManage) {
this.courseManage = courseManage;
}
@Override
protected ModelAndView handleRequestInternal(HttpServletRequest request,
HttpServletResponse response) throws Exception {
Integer course_id=new Integer(request.getParameter("course_id"));
List courseList=this.courseManage.getCourseById(course_id);
List studentList = this.courseManage.getStudentByCourseId(course_id);
try {
OutputStream os = response.getOutputStream();// 取得输出流
response.reset();// 清空输出流
response.setHeader("Content-disposition", "attachment; filename=student.xls");// 设定输出文件头
response.setContentType("application/msexcel");// 定义输出类型
ExcelBean excelBean = new ExcelBean();
excelBean.expordExcel(os,courseList,studentList);// 调用生成excel文件bean
} catch (Exception e) {
System.out.println(e);
}
return null;
}
}
将Excel文件内容写入到数据库
Java代码
publicclass EStudentInsertExcelController extends SimpleFormController{
private IStudent_infoManage studentManage;
@Override
protected ModelAndView onSubmit(HttpServletRequest request,
HttpServletResponse response, Object command, BindException errors)
throws Exception{
Student_info student_info = (Student_info) command;
try;{
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
MultipartFile file = multipartRequest.getFile( " Excelfile " ); // 获得文件：
File toFile =new File( " c:\\学生信息临时文件.xls " ); // 产生文件名和空文件
file.transferTo(toFile); // 文件上传
Workbook book = Workbook.getWorkbook(toFile); // 得到工作薄
Sheet sheet = book.getSheet( 0 ); // 获得第一个工作表对象
int row = sheet.getRows(); // /得到该sheet的行数
int column = sheet.getColumns(); // 得到该sheet的列数
System.out.println( " 数据行数= " + row);
System.out.println( " 数据列数= " + column);
for ( int i = 1 ;i < row;i ++ )
{
for ( int j = 0 ;j < column;j ++ )
{
System.out.println( " j= " + j);
sheet.getCell(j, i).getContents(); // 得到第j列第i行的单元格的类容
student_info.setStudentID(sheet.getCell(j, i).getContents());
........................
}
if ( this .studentManage.getStudentByStudentID(
student_info.getStudentID()).size() !=0 )
returnnew ModelAndView( " education/e-studentInfoAddError " );
this .studentManage.insertStudent_info(student_info);
}
book.close();
returnnew ModelAndView( " education/e-studentInfoAddExcelSuccess " , " row " , new Integer(row - 1 ));
}catch (Exception e){
e.printStackTrace();
}
returnnew ModelAndView( " education/e-studentInfoAddExcelError " );
}
publicvoid setStudentManage(IStudent_infoManage studentManage){
this .studentManage = studentManage;
}
}
spring 生成Excel和PDF文件
HTML页面并不总是向用户显示数据输出的最好方式，有时候需要生成不可改变的文件打印，PDF可能是种不错的选择。
Spring支持从数据动态生成PDF或Excel文件
下面这个简单实现的例子实现了spring输出PDF和Excel文件，为了使用Excel电子表格，你需要在你的classpath中加入poi-2.5.1.jar库文件，而对PDF文件，则需要iText.jar文件。它们都包含在Spring的主发布包中。
下面是测试项目代码：
1、控制器配置代码
