2、js数据提交

$("#importBtn").click(function(){

                  return;

                  alert("请填写会议的简称");
                  return;
              }
              if($("#importFile").val() == ''){
                  alert("请选择上传的文件")
                  return;
              }
              if($("#seanceId").val() == -1){
                  alert("请选择注册类型");
                  return;
              }else{$("#daoru").html("导入中...");}
              setTimeout(function(){

                formData.append("teamName",teamName);
                formData.append("conId",conId);
                formData.append("seanceId",$("#seanceId").val());
                $.ajax({
                        url: "/import.do?importUser",
                        type: 'POST',
                        data: formData,

                        contentType: false,
                        cache:false,
                        ifModified:true,
                        async:false,
                        beforeSend: function () {
                            console.log("正在进行，请稍候");
                        },
                        success: function (json) {
                            if (json.state == 1) {

                                window.location.reload();
                                //$("#selectFile").html("选择文件");
                            } else {
                                alert(json.msg);
                                return;
                            }
                        },
                        error: function (json) {
                            console.log("error");

                    });
              },100)
          })

3、后台数据处理

    public void importUser(Integer conId,Integer seanceId,HttpServletRequest request,HttpServletResponse response){
        try {
            MultipartHttpServletRequest mRequest = (MultipartHttpServletRequest) request;
            MultipartFile mFile = mRequest.getFile("importFile");
            String fromWhere = request.getParameter("fromWhere");
            String teamName = request.getParameter("teamName");
            teamName = URLDecoder.decode(teamName,"UTF-8");
            UserInfo teamUser = null;
            if(teamName.length() > 0){//要创建团队
                System.out.println(teamName);
                teamUser = userinfoService.getTeamUser(fromWhere,teamName);
                if(teamUser == null){
                    teamUser = new UserInfo();
                    teamUser.setTrueName(teamName);
                    teamUser.setDanwei(teamName);
                    teamUser.setHospitalName(teamName);
                    teamUser.setIsTeam(1);
                    teamUser.setIsTeamLeader(1);
                    teamUser.setFromWhere(fromWhere);
                    teamUser.setConferencesId(conId);
                    userinfoService.saveOrUpdate(teamUser);
                    teamUser.setTeamId(teamUser.getUserInfoId());
                    userinfoService.saveOrUpdate(teamUser);
                }
            }

                    for(; it !=null && it.hasNext();){
                        Row row = (Row)it.next();
                        if(row==null)

                            int columnNum = row.getPhysicalNumberOfCells();
