上傳，解析Excel檔案並儲存資料到資料庫
web框架：spring+hibernate+jQuery
HTML端程式碼：
<div class="file-up-content">
<table id="fileDiv" class="table">
<tr>
<td colspan="3"> 請採用excel檔案格式。 <input type="hidden" id="isHaveAttFile" name="isHaveAttFile"
value="0" /> <input type="hidden" id="resultfileurls"
name="resultfileurls" value="${report.resultinfoListString}" />
</td>
</tr>
<tr>
<td valign="top" colspan="3">
<table>
<tr id="fileList">
<c:if test="${!empty rinfoList }">
<c:forEach items="${rinfoList}" var="item" varStatus="var">
<tr id="p_${item.id }">
<td><a id="p_${item.id }_a" href="<c:url value='${item.localurl}'/>" target="_blank">${item.localurl }</a>
<a href="javascript:;" onclick="removePic('${item.id}', '${item.localurl }','removefile', '${novkjcx.id }');">x</a>
</td>
</tr>
</c:forEach>
</c:if>
</tr>
</table>
<span id="uploadfileButton" style="color:#6699CC; cursor:pointer " title="點選繼續新增！">新增附件</span>
<span id="resultfileurlsShowMessage" style="color: red"></span>
</td>
<td> <br /></td>
</tr>
</table>
</div>

後端controller程式處理程式碼：
protected void formSubmit(HttpServletRequest request,
HttpServletResponse response, Object command, Errors errors,
PmUserSession userSession, PageSession pageSession)
throws Exception {
String attid=request.getParameter("attid"); //attid為對應Excel檔案的UUID號
if(WebUtils.isNotNull(attid)){
List<AAA> rinfoList=dao.find(" from AAA obj where obj.attid='"+attid+"' and del=0"); //AAA為資料庫中存檔案路徑的表名用hibernate對映之後的名稱
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"));
}
}
}
呼叫ImportTerm類的方法：
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上傳解析入庫完成。方法多種多樣，熟練一種就可以了。
