这里省略spring配置，就是简单的SMM配置
1.前端我用了一个网上找的esyUI的框架
在前端引入
<link rel="stylesheet" href="static/ace/css/font-awesome.min.css" /> <link rel="stylesheet" type="text/css" href="static/jquery-easyui-1.3.3/themes/default/easyui.css"> <link rel="stylesheet" type="text/css" href="static/jquery-easyui-1.3.3/themes/icon.css"> <style type=text/css><script type="text/javascript" src="static/jquery-easyui-1.3.3/jquery.min.js"></script> <script type="text/javascript" src="static/jquery-easyui-1.3.3/jquery.easyui.min.js"></script> <script type="text/javascript" src="static/jquery-easyui-1.3.3/locale/easyui-lang-zh_CN.js"></script>按钮
<td><div><a href="javascript:void(0)" class="easyui-linkbutton" iconCls="icon-import " plain="true" onclick="openUploadFileDialog()">批量导入数据</a></div></td>按钮弹窗
<div id="dlg2" class="easyui-dialog"
style="width: 400px; height: 180px; padding: 10px 20px"
closed="true" buttons="#dlg-buttons2">
<form id="uploadForm" action="readCaseNumber/sendCase.do" method="post" enctype="multipart/form-data">
<table>
<tr>
<td>上传文件：</td>
<td><input type="file" name="upfile"></td>
</tr>
</table>
</form>
</div>
<div id="dlg-buttons2">
<a href="javascript:void(0)" class="easyui-linkbutton"
iconCls="icon-ok" onclick="uploadFile()">上传</a> <a
href="javascript:void(0)" class="easyui-linkbutton"
iconCls="icon-cancel"
onclick="javascript:$('#dlg2').dialog('close')">关闭</a>
</div>
漏了js代码
<script>
function openUploadFileDialog(){
$("#dlg2").dialog('open').dialog('setTitle','导入数据');
}
function uploadFile(){
$("#uploadForm").form("submit",{
success:function(result){
var result=eval('('+result+')');
if(result.errorMsg){
$.messager.alert("系统提示",result.errorMsg);
}else{
$.messager.alert("系统提示","上传成功");
$("#dlg2").dialog("close");
$("#dg").datagrid("reload");
}
}
});
}
后端controller
@Controller
@RequestMapping(value = "/readCaseNumber")
public class ReadCaseNumber extends BaseController {
@RequestMapping(value = "/sendCase")
@ResponseBody
public String sendCase(HttpServletRequest request) throws Exception {System.out.println("开始上传文件");
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
System.out.println("通过传统方式form表单提交方式导入excel文件！");
CaseNm caseNm = new CaseNm();
List<String> caseNumbers = caseNm.upload(multipartRequest);上面 就是获取前端请求的注解
MultipartHttpServletRequest 可以网上查一下
我的业务是获取Excel表格第一sheet页的第一列的数据，返回第一行数据的数组的工具类
public List<String> upload(MultipartHttpServletRequest multipartRequest) throws Exception {
InputStream in = null;
List<List<Object>> listob = null;
MultipartFile file = multipartRequest.getFile("upfile");
if (file.isEmpty()) {
throw new Exception("文件不存在！");
}
in = file.getInputStream();
listob = new ImportExcelUtil().getBankListByExcel(in, file.getOriginalFilename());
// 因为要导入的excel比较特殊，不是常规的一行类别，其他行都是数据，所以我需要根据具体模板来读取excel
List<String> list = new ArrayList<>();
for (int i = 0; i < listob.size(); i++) {
DetailInfoVo vo = new DetailInfoVo();
List<Object> list2 = listob.get(i);
//vo.setCaseNm(String.valueOf(listob.get(i).get(1)));
System.out.println(list2.toString());
list.add((String)list2.get(0));
}
System.out.println(list.toString());
in.close();
return list;
}
验证Excel是2003的xls还是2007的xlsx工具类
public class ImportExcelUtil {
private final static String excel2003L =".xls"; //2003- 版本的excel
private final static String excel2007U =".xlsx"; //2007+ 版本的excel
/**

public List<List<Object>> getBankListByExcel(InputStream in,String fileName) throws Exception{
List<List<Object>> list = null;
//创建Excel工作薄
Workbook work = this.getWorkbook(in,fileName);
if(null == work){
throw new Exception("创建Excel工作薄为空！");
}
Sheet sheet = null;
Row row = null;
Cell cell = null;
list = new ArrayList<List<Object>>();
//遍历Excel中所有的sheet
int s=work.getNumberOfSheets();
for (int i = 0; i < work.getNumberOfSheets(); i++) {
sheet = work.getSheetAt(i);
if(sheet==null){continue;}
int s2=sheet.getLastRowNum();
//遍历当前sheet中的所有行
for (int j = sheet.getFirstRowNum(); j <= sheet.getLastRowNum(); j++) {

if(row==null||row.getFirstCellNum()==j){continue;}

List<Object> li = new ArrayList<Object>();
for (int y = row.getFirstCellNum(); y < row.getLastCellNum(); y++) {

li.add(this.getCellValue(cell));
}
list.add(li);
}
}
work.close();
return list;
