2014-10-23 22:38 519 查看

页面设置：uploadexcel.jsp

<body>
<form action="excel.do?method=uploadfile" method="post" enctype="multipart/form-data">
<input type="file" value="文件" name="file" >
<input type="submit" value="提交">
</form>
</body>
spring注解，接收文件

@Controller
@RequestMapping("/excel.do")
public class ExcelUpLoadAction {

@Autowired
private RecruithighstuService2 reService;

@RequestMapping(params = "method=uploadfile", method = RequestMethod.POST)
public void doUpload(HttpServletRequest request,
HttpServletResponse response) throws IOException {

// 文件上传上传到哪里

MultipartHttpServletRequest mr = (MultipartHttpServletRequest) request;

// 获取上传的文件
MultipartFile multiFile = (MultipartFile) mr.getFile("file");

// 获得文件全名
String fname = multiFile.getOriginalFilename();

String pathfile = "D:/Tomcat6.0/webapps/sunjob_management_system/excels"+"/"+fname;
<span style="white-space:pre"> </span>
File file = new File(pathfile);
try {

<span style="white-space:pre">			</span>//文件提交
multiFile.transferTo(file);

} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
reService.getExcelData(pathfile);

}

}

server配置：

@Service
public class RecruithighstuService2 {

Recruithighstu stu=new Recruithighstu();

@Autowired
private ExcelUploadDAO excelUploadDAO;
@Autowired
private RecruitstudentDAO rsDao;

@Autowired
private RecruithighstuDAO dao;

public void writeInMYSQL(String path, List readList) {

// 循环一次得到一行的数组
for (int i = 0; i < readList.size()-2; i++) {
System.out.println(readList.size());
String[] colArr = (String[]) readList.get(i);
rsDao.findById(Integer.parseInt(colArr[0]));
stu.setRecruitstudent(rsDao.findById(Integer.parseInt(colArr[0])));
stu.setRhName(colArr[1]);

stu.setRhSex(Integer.parseInt(colArr[2]));
stu.setRhAddress(colArr[3]);
stu.setRhSchool(colArr[4]);
stu.setRhPhone(colArr[5]);

stu.setRhFphone(colArr[6]);
stu.setRhMphone(colArr[7]);
stu.setRhQq(colArr[8]);
System.out.println(colArr[8]);
System.out.println(colArr[9]);
stu.setRhNote(colArr[9]);
//dao.save(stu);
excelUploadDAO.save(stu);
System.out.println(dao.findAll());
}

}

public List getExcelData(String path) {
// 流操作
// InputStream此抽象类是表示字节输入流的所有类的超类。
// FileInputStream 从文件系统中的某个文件中获得输入字节

InputStream inputStream = null;
List readList = new ArrayList();
Workbook workbook = null;
// 得到工作薄对象
// System.out.println(path);
try {
inputStream = new FileInputStream(path);
workbook = Workbook.getWorkbook(inputStream);
// 通过工作表名字获得工作表对象。
Sheet sheet = workbook.getSheet("Sheet1");
// 获得行数
int rows = sheet.getRows();
// 得到当前行所有的单元格
for (int i = 1; i < rows; i++) {
// 得到当前行所有的单元格
Cell[] cell = sheet.getRow(i);
// 定义数组
String[] colArr = new String[cell.length];
// 循环当前单元格
for (int j = 0; j < cell.length; j++) {
// 取得当前单元格的内容
colArr[j] = cell[j].getContents().trim();
// System.out.println(colArr[j]);
}
readList.add(colArr);

}

} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
if (inputStream != null) {
workbook.close();
try {
inputStream.close();
} catch (IOException e) {

e.printStackTrace();
}

}

}
writeInMYSQL(path, readList);
return readList;
}

}

dao层
public class ExcelUploadDAO extends HibernateDaoSupport{

public void save(Object object)
{
getHibernateTemplate().save(object);

getHibernateTemplate().flush();
//一定要清空缓存，不然只能会保存最后一条数据，其他数据保存不了
getHibernateTemplate().clear();
}

}
