首先 ，引入相关依赖EasyPOI

        <dependency>
            <groupId>cn.afterturn</groupId>
            <artifactId>easypoi-spring-boot-starter</artifactId>
            <version>4.4.0</version>
        </dependency>

编写实体类： 

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
    private Integer id;
    private String username;
    private String password;
    private String email;
    private Integer age;
    private String phone;
    private Integer isDeleted;
}

 编写控制类UserController：

@RestController
public class UserController {
    @SneakyThrows
    @GetMapping("export")
    public void exportExcel(HttpServletResponse response){
        List<User> list = new ArrayList<>();
        list.add(new User(1,"zhangsan","aaa","28181@163.com",18,"13256564454",1));
        list.add(new User(2,"lisi","aaa","28181@163.com",28,"18456234454",0));
        list.add(new User(3,"Wangwu","aaa","28181@163.com",38,"18423564454",1));
        list.add(new User(4,"mazi","aaa","28181@163.com",15,"18456564454",1));

        // 传入表头和表名
        ExportParams exportParams = new ExportParams("员工信息表","员工表");
        Workbook sheets = ExcelExportUtil.exportExcel(exportParams,User.class,list);

        //设置响应输出的类型为excel
        response.setContentType("application/vnd.ms-excel");
        //设置相应的文件名

        String filename = UUID.randomUUID() + ".xlsx";
        response.setHeader("Content-disposition","attachment;filename="+ new String(filename.getBytes("utf-8"),"iso8859-1"));

        sheets.write(response.getOutputStream());
    }
}

实现导出元素：

现在进行导入操作：

    @SneakyThrows
    @PostMapping("import")
    public AjaxResult importExcel(@RequestParam(value = "file") MultipartFile file){
        ImportParams params = new ImportParams();
        params.setTitleRows(1);// 标题行数
        params.setHeadRows(1); // 列名行数

        List<User> list = ExcelImportUtil.importExcel(file.getInputStream(), User.class, params);

        list.forEach(System.out::println);
        return success();
    }

使用postman进行导入测试：

导入的表格元素入下所示：
