springmvc+mybatis +poi实现导入exce数据l到数据库中

1.项目用到的是poi技术,需要在maven文件添加如下配置:

			org.apache.poi
			poi
			3.14


	   org.apache.poi
	   poi-ooxml
	   3.6

2.在springMVC.servlet.xml配置bean:

  
          
          
            104857600  
          
          
            4096  
          
     

excel数据如下

3.jsp页面部分代码:

    
    选择文件  
      
                                          
  
上传

引入的js:

var MobileUser = function(){  
      
    this.init = function(){  
          
        //模拟上传excel  
         $("#uploadEventBtn").unbind("click").bind("click",function(){  
             $("#uploadEventFile").click();  
         });  
         $("#uploadEventFile").bind("change",function(){  
             $("#uploadEventPath").attr("value",$("#uploadEventFile").val());  
         });  
          
    };  
    //点击上传按钮  
    this.uploadBtn = function(){  
        var uploadEventFile = $("#uploadEventFile").val();  
        if(uploadEventFile == ''){  
            alert("请选择excel,再上传");  
        }else if(uploadEventFile.lastIndexOf(".xls")<0){//可判断以.xls和.xlsx结尾的excel  
            alert("只能上传Excel文件");  
        }else{  
            var url =  '/sign/mobile/batchImport';  
            var formData = new FormData($('form')[4]);  
            user.sendAjaxRequest(url,'POST',formData);  
        }  
    };  
      
    this.sendAjaxRequest = function(url,type,data){  
        $.ajax({  
            url : url,  
            type : type,  
            data : data,  
            success : function(result) {  
            	alertMsg.correct( "excel上传成功");  
            },  
            error : function() {  
            	alertMsg.error( "excel上传失败"); 
            },  
            cache : false,  
            contentType : false,  
            processData : false  
        });  
    };  
}  
      
  
var user;  
$(function(){  
    user = new MobileUser();  
    user.init();  
});
