一个小方法,字节流读取.xls文件,将表内容写入到对应数据库表中

省略了数据库表对应的实体类与插入数据库一行数据的代码,要实现此方法需要在网上下载jxl.jar这个包

public List<Student> readxls(File file) {

List<Student> ls=new ArrayList<Student>();

Workbook workbook=null;

try {

workbook=Workbook.getWorkbook(file);

Sheet sheet=workbook.getSheet(0);

for (int i = 0; i < sheet.getRows(); i++) {

Student student=new Student();

student.setId(Integer.parseInt(sheet.getCell(0,i).getContents()));

student.setName(sheet.getCell(1,i).getContents());

student.setPassword(sheet.getCell(2,i).getContents());

student.setAge(Integer.parseInt(sheet.getCell(3,i).getContents()));

student.setSex(sheet.getCell(4,i).getContents());

ls.add(student);

}

} catch (BiffException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}finally{

workbook.close();

}

return ls;

}

public class Test {

public static void main(String[] args) {

Dao<Student> ds=StudentManagerFactory.factory();

File file=new File("D:\\学生.xls");

List<Student> list=ds.readxls(file);

for (int i = 0; i < list.size(); i++) {

Student s=list.get(i);

ds.insert(s);

}

}

}
