注：@ExcelProperty(value = “xxxxx”,index =3)其中value 为列名，index 为列的序号

service类

 public List< Students> exports() {
        return studentMapper.exports();
    }

mapper

 List< Students> exports();

mapper.xml文件

    
    id, number, name, type, password
  

    select
    
    from student
  

运行看看效果：
