本案例承接以前的SSM整合系列，针对Oracle中的Dept表做操作，如果单击浏览，则进行批量导入；单击2则是单个导入。ssm之九 批量导入excel到数据库

批量导入部门的控制器代码: 

package com.aaa.ssm.controller;import java.io.IOException;import java.io.InputStream;import java.util.Enumeration;import java.util.HashMap;import java.util.List;import java.util.Map;import javax.servlet.http.HttpServletRequest;import jxl.Cell;import jxl.Sheet;import jxl.Workbook;import jxl.read.biff.BiffException;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.bind.annotation.ResponseBody;import org.springframework.web.multipart.MultipartFile;import com.aaa.ssm.entity.Dept;import com.aaa.ssm.service.IDeptService;import com.aaa.ssm.util.PageData;import com.aaa.ssm.util.PageUtil;/** *@classname:DeptController.java *@discription:部门 控制器,负责与前后台及模型交互 * *@author:zhz *@createtime:2017-4-13上午09:09:16 *@version:1.0 */@Controller@RequestMapping("/dept")public class DeptController {   @Autowiredprivate IDeptService service;/** * 部门列表方法 * @return */@RequestMapping("/list")public String list(Model model,Integer pageNo,HttpServletRequest request){/*System.out.println("URI地址："+request.getRequestURI());Enumeration  pNames=request.getParameterNames();   while(pNames.hasMoreElements()){    String  name=(String)pNames.nextElement();  System.out.println("name:"+name+"="+request.getParameter(name)); }*/int pageSize=2;if(pageNo==null){pageNo=1;}Map map =new HashMap();map.put("start", (pageNo-1)*pageSize);map.put("end", pageNo*pageSize+1);PageData pageData = service.getList(map);int count = pageData.getCount();//总数量String pageString = new PageUtil(pageSize, pageNo, count, request).getPageString();model.addAttribute("deptList", pageData.getList());model.addAttribute("pageString", pageString);return "dept/list";}/** * 批量导入部门信息 * @param mFile * @return * @throws IOException * @throws BiffException  */@RequestMapping("/deptImp")public String deptImport(@RequestParam MultipartFile mFile) throws IOException, BiffException{//获取文件流InputStream inputStream = mFile.getInputStream();//利用JAR提供的Workbook类读取文件Workbook workbook = Workbook.getWorkbook(inputStream);//获取工作薄Sheet sheet = workbook.getSheet(0);//获取总行数int rows = sheet.getRows();//获取总列数int cells = sheet.getColumns();//循环读取数据Dept dept = null;for(int i=1;i<rows;i++){dept = new Dept();Cell[] cell=sheet.getRow(i);dept.setDeptNo(Integer.valueOf(cell[0].getContents()));dept.setdName(cell[1].getContents());dept.setLoc(cell[2].getContents());service.add(dept);/*for(int j=0;j<cells;j++){System.out.println(cell[j].getContents());}*/}return "redirect:list";}/** * 返回DeptJson * @return */@ResponseBody@RequestMapping("/deptJson")public Object deptJson(){Map map =new HashMap();map.put("start", 0);map.put("end", 100);PageData pageData = service.getList(map);int count = pageData.getCount();//总数量List<Dept> deptList = pageData.getList();Map mapJson =new HashMap();mapJson.put("total", count);mapJson.put("rows", deptList);return mapJson;}/** * 跳转添加方法 * @return */@RequestMapping("/toAdd")public String toAdd(){return "dept/add";}/** * 添加方法 * @param dept * @return */@RequestMapping("/add")public String add(Dept dept,Model model){ try {service.add(dept);return "redirect:list";} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();model.addAttribute("errormsg", "添加部门失败！");return "dept/add";}}/** * 跳转部门更新 * @return */@RequestMapping("/toUpdate")public String toUpdate(Model model,int deptNo){Dept dept =  service.getById(deptNo);model.addAttribute("dept", dept);return "dept/update";}/** * 部门更新 * @param dept * @return */@RequestMapping("/update")public String update(Dept dept){service.update(dept);return "redirect:list";}/** * 部门删除 * @return */@RequestMapping("/del")public String delete(Integer deptNo){service.delete(deptNo);return "redirect:list";}}

服务层Service的代码: 

package com.aaa.ssm.service;import java.util.List;import java.util.Map;import com.aaa.ssm.entity.Dept;import com.aaa.ssm.util.PageData;/** *@classname:IDeptService.java *@discription:部门业务类接口 * *@author:zhz *@createtime:2017-4-13上午09:06:39 *@version:1.0 */public interface IDeptService {/** * 根据部门编号获取部门对象 * @return */public Dept getById(int deptNo);/** * 部门列表 * @return */public PageData getList(Map map);/** * 部门添加 * @param dept */public void add(Dept dept);/** * 部门更新 * @param dept */public void update(Dept dept);/** * 部门删除 * @param deptNo */public void delete(int deptNo);}
服务层实现类和以前的一样： 

/** * 部门添加 */public void add(Dept dept) {// TODO Auto-generated method stubdao.add(dept);//System.out.println(1/0);}

扩展篇，该段示例代码只能实现，批量导入dept表中的数据到数据库，如何实现批量如何多个表呢？
