环境说明

jdk1.8，springboot2.5.3

项目结构

1.controller层

package com.example.pdf.controller;import com.example.pdf.service.ReadExcelFileService;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;import javax.annotation.Resource;@RestController
@RequestMapping(value = "read")
public class ReadExcelFileController {@Resourceprivate ReadExcelFileService readExcelFileService;@PostMapping("excelFile")public void excelFile(@RequestBody MultipartFile file) {readExcelFileService.excelFile(file);}
}

2.service层

package com.example.pdf.service;import org.springframework.web.multipart.MultipartFile;public interface ReadExcelFileService {/*** 读excel表格数据* */void excelFile(MultipartFile file);
}

实现层

package com.example.pdf.service.impl;import com.alibaba.excel.EasyExcel;
import com.alibaba.excel.read.listener.PageReadListener;
import com.example.pdf.model.StudentModel;
import com.example.pdf.service.ReadExcelFileService;
import org.springframework.stereotype.Service;
import org.springframework.web.multipart.MultipartFile;@Service
public class ReadExcelFileServiceImpl implements ReadExcelFileService {/*** 读excel表格数据** @param file*/@Overridepublic void excelFile(MultipartFile file) {try {// 最高缓存量，放满后存储一次数据库，然后清空缓存int batchCount = 100;EasyExcel.read(file.getInputStream(), StudentModel.class, new PageReadListener<StudentModel>(list -> {System.out.println("已完成" + list.size() + "条车辆数据读取...");for (StudentModel studentModel : list) {System.out.println("学生姓名：" + studentModel.getName() + ",学生年龄：" + studentModel.getAge());}}, batchCount)).sheet(0).doRead();} catch (Exception e) {System.out.println("读取数据异常！");}}
}

StudentModel.java类

package com.example.pdf.model;import com.alibaba.excel.annotation.ExcelProperty;
import lombok.Data;@Data
public class StudentModel {@ExcelProperty("姓名")private String name;@ExcelProperty("年龄")private Integer age;}

使用的Maven依赖

<!-- lombok插件 --><dependency><artifactId>lombok</artifactId><groupId>org.projectlombok</groupId><scope>provided</scope><version>1.18.10</version></dependency><!-- alibaba Excel --><dependency><groupId>com.alibaba</groupId><artifactId>easyexcel</artifactId><version>3.3.2</version></dependency>
