ssm框架上传Excel解析到数据库

最近在项目中有用到上传Excel，将数据解析到数据库，在网上找了很多资源，在此做个总结：
1、首先放上要运到的jar包
jar包传送门
提取码： ha4p
2、接下来有这两个工具类，不用改变，可以直接使用

package com.grand.common.util;

import org.apache.poi.xssf.usermodel.XSSFCellStyle;
public class ExcelBean implements java.io.Serializable {  
    /**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	private String headTextName;//列头（标题）名  
    private String propertyName;//对应字段名  
    private Integer cols;//合并单元格数  
    private XSSFCellStyle cellStyle;  
      
    public ExcelBean(){  
          
    }  
    public ExcelBean(String headTextName, String propertyName){  
        this.headTextName = headTextName;  
        this.propertyName = propertyName;  
    }  
      
    public ExcelBean(String headTextName, String propertyName, Integer cols) {  
        super();  
        this.headTextName = headTextName;  
        this.propertyName = propertyName;  
        this.cols = cols;  
    }   
      
    public String getHeadTextName() {  
       return headTextName;  
   }  
 
   public void setHeadTextName(String headTextName) {  
       this.headTextName = headTextName;  
   }  
 
   public String getPropertyName() {  
       return propertyName;  
   }  
 
   public void setPropertyName(String propertyName) {  
       this.propertyName = propertyName;  
   }  
 
   public Integer getCols() {  
       return cols;  
   }  
 
   public void setCols(Integer cols) {  
       this.cols = cols;  
   }  
 
   public XSSFCellStyle getCellStyle() {  
       return cellStyle;  
   }  
 
   public void setCellStyle(XSSFCellStyle cellStyle) {  
       this.cellStyle = cellStyle;  
   }  
}
