导入excel hutool工具

第一步 : 导包

(需要注意这里包的版本号有很大问题需要注意 !!!)

<dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi</artifactId>
        <version>4.0.0</version>
    </dependency>
    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml</artifactId>
        <version>4.0.0</version>
    </dependency>
    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml-schemas</artifactId>
        <version>4.0.0</version>
    </dependency>

接下来就简单了

第二步 : 不知道怎么描述了->看代码

1. 首先 必须要有个和excel 标题对应的类

@Data
public class Student {

    private String id;

    private String name;

    private String age;
}

其次

ExcelReader reader = ExcelUtil.getReader("d:\\aaa.xlsx");
        reader.addHeaderAlias("编号","id");
        reader.addHeaderAlias("姓名","name");
        reader.addHeaderAlias("年龄","age");
        List<Student> readAll = reader.readAll(Student.class);
