一个方便读取excel内容,且可以使用注解进行内容验证的包装工具
- 在easyexcel的基础上进行封装,方便读取excel内容,避免在主业务代码中嵌入重复繁琐的样本代码
- 支持Hibernate-validator验证框架,可使用诸如@NotBlank,@NotDuiplicate的注解
- 1、新建一个JavaBean用于接收excel内容,并继承ExcelRow基础类,如:新建MyRow.java
import com.alibaba.excel.annotation.ExcelProperty;
import com.wuyue.excel.ExcelRow;
import com.wuyue.excel.validate.NotDuplicate;
import lombok.Getter;
import lombok.Setter;
import lombok.ToString;
import org.hibernate.validator.constraints.Email;
import org.hibernate.validator.constraints.NotBlank;
@Getter
@Setter
@ToString
public class MyRow extends ExcelRow {
@ExcelProperty(index = 0)
@NotDuplicate
@NotBlank(message = "名称不能为空")
private String name;
@ExcelProperty(index = 1)
@Email
private String email;
}
- 2、调用ExcelUtil.read方法,获取excel内容
File file = new File("D:\\1.xlsx");
FileInputStream fileInputStream = new FileInputStream(file);
List<MyRow> rows = ExcelReader.builder()
.inputStream(fileInputStream)
.sheetNo(1)
.headLineMun(1)
.build()
.read(MyRow.class);
- 3、主业务功能代码使用“行”内容的校验结果
System.out.println(rows);
rows.forEach(row -> {
// 行号,如果要提示实际excel行号,应该要加上headLineMun的值
System.out.print("Row number:" + row.getRowNum());
// 校验结果代码(0为正常)
System.out.print(", validate code:" + row.getValidateCode());
// 校验结果内容
System.out.println(", message:" + row.getValidateMessage());
});
输出结果如下:
[MyRow(name=felix, email=5401142), MyRow(name=wuyue, email=540114289@qq.com), MyRow(name=felix, email=null), MyRow(name=wuyue, email=null)]
Row number:1, validate code:2, message:不是一个合法的电子邮件地址
Row number:2, validate code:0, message:null
Row number:3, validate code:1, message:Duplicate field
Row number:4, validate code:1, message:Duplicate field
