后端controller程序处理代码：

protected void formSubmit(HttpServletRequest request,

HttpServletResponse response, Object command, Errors errors,

PmUserSession userSession, PageSession pageSession)

throws Exception {

String attid=request.getParameter("attid"); //attid为对应Excel文件的UUID号

if(WebUtils.isNotNull(attid)){

List<AAA> rinfoList=dao.find(" from AAA obj where obj.attid='"+attid+"' and del=0"); //AAA为数据库中存文件路径的表名用hibernate映射之后的名称

if(rinfoList.size()>0){

File f=new File(rinfoList.get(0).getLocalurl());

ImportTerm i=new ImportTerm();

i.importTerm(f, dao,attid);

response.sendRedirect(request.getContextPath() + "/embed/datasetElement.htm?id="+request.getParameter("dataset"));

}

}

}

调用ImportTerm类的方法：

package cn.nsl.data;

import java.io.File;

import java.util.List;

import org.apache.poi.ss.usermodel.Row;

import org.apache.poi.ss.usermodel.Sheet;

import org.apache.poi.ss.usermodel.Workbook;

import org.apache.poi.ss.usermodel.WorkbookFactory;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import cn.nsl.domain.glob.DataSet;

import cn.nsl.domain.glob.DataSetElement;

import cn.nsl.domain.glob.Elements;

import cn.nsl.web.Application;

import com.jbetter.spring.orm.ICommonDao;

public class ImportTerm extends ImportExcel {

public void importTerm(File f,ICommonDao dao,String attid){

try {

Workbook wb;

wb = WorkbookFactory.create(f);

Sheet sheet = wb.getSheet("Sheet1");

importTermSheet(sheet,dao,dataset,attid);

} catch (Exception e) {

// TODO Auto-generated catch block

log.error(e);

e.printStackTrace();

}

}

void importTermSheet(Sheet sheet,ICommonDao dao,DataSet dataset,String attid) throws Exception{

int rowEnd = Math.max(100, sheet.getLastRowNum());

for(int i=1;i<=rowEnd;i++){

importTermProd(sheet.getRow(i),dao,dataset,attid);

}

}

void importTermProd(Row r,ICommonDao dao,DataSet dataset,String attid) throws Exception{

String code=getString(r, 0);

String cnname = getString(r, 1);

String name = getString(r, 2);

String frequency = getString(r, 3);

String limiting = getString(r, 4);

String multiJATS = getString(r, 5);

String remarks = getString(r, 6);

biaoming c = new biaoming();

c.setFrequency(frequency);

c.setLimiting(limiting);

c.setMultiJATS(multiJATS);

c.setRemarks(remarks);

c.setAttid(attid);

dao.save(c);

}

public static void main(String []args){

System.setProperty("file.encoding", "UTF-8");

ApplicationContext apx = new ClassPathXmlApplicationContext("applicationContext-hibernate.xml");

dao = (ICommonDao) apx.getBean("commonDao");

ImportTerm i = new ImportTerm();

i.importTerm(new File("D://term.xlsx"),dao,null,"dd");

}

}

到此Excel上传解析入库完成。方法多种多样，熟练一种就可以了。
