废话不多说，直接上代码，简单易懂，好好学
- 架构：SpringBoot+Mybatis
- 数据库：Mysql5
- 导入依赖，版本随便
org.apache.poi
poi-ooxml
3.15-beta2
org.apache.poi
poi
4.0.1
org.projectlombok
lombok
1.18.20
provided
- 实体类：每个字段对应Excel表格中的一个表头字段名字，实际字段根据自己的实际情况
import lombok.Data;
import java.io.Serializable;
@Data
public class Detailed implements Serializable {
public Long id;
public String auditDate;
public Integer sceneId;
public String sceneName;
public String entityid;
public Long housingResourcesId;
public Integer cityid;
public String firstInstanceOA;
public String firstInstance;
public String preliminaryResults;
public String reasonsForFirstInstance;
public String timeOfInitialExaminationAndStorage;
public String initialAuditTime;
public Double shenheshichang;
public String timeoutStatus;
public String qualityInspectionResults;
public String qualityInspectionReasons;
public String qualificationStatus;
}
- 两个utils：
-
- ReadLocalFileUtils：获取本地指定文件夹下的文件，文件夹里必须都是Excel文件
import java.io.File;
import java.util.ArrayList;
import java.util.List;
public class ReadLocalFileUtils {
public static List getFile(String path) {
// 创建集合，用来储存文件名称
ArrayList-
- XlsxUtils：读取Excel中的数据。这里的
// 获取目标单元格的值并存进对象中根据自己的实体类进行编写，实体类是String类型的不用转类型，不是得得转类型
- XlsxUtils：读取Excel中的数据。这里的
import com.iyunfish.tongcheng.domain.Detailed;
import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
public class XlsxUtils {
public static List read(String path) throws IOException {
// 建立输入流
FileInputStream fileInputStream = new FileInputStream(path);
// 在输入流中获取工作簿
XSSFWorkbook workbook = new XSSFWorkbook(fileInputStream);
// 在工作簿获取目标工作表
XSSFSheet sheetAt = workbook.getSheetAt(0);
// 获取到最后一行
int physicalNumberOfRows = sheetAt.getPhysicalNumberOfRows();
// 创建集合，用来储存储存行的对象
ArrayList detaileds = new ArrayList<>();
// 遍历整张表的所有行，从第二行开始，第一行表头不要，所以循环的下表从1开始
for (int i = 1; i < physicalNumberOfRows; i++) {
// 创建对象用来存行数据
Detailed detailed = new Detailed();
// 获取当前行数据，不是行数
XSSFRow row1 = sheetAt.getRow(i);
// 获取目标单元格的值并存进对象中
detailed.setAuditDate(row1.getCell(0).getStringCellValue());
detailed.setSceneId(Integer.valueOf(row1.getCell(1).getStringCellValue()));
detailed.setSceneName(row1.getCell(2).getStringCellValue());
detailed.setEntityid(row1.getCell(3).getStringCellValue());
detailed.setHousingResourcesId(Long.valueOf(row1.getCell(4).getStringCellValue()));
detailed.setCityid(Integer.valueOf(row1.getCell(5).getStringCellValue()));
detailed.setFirstInstanceOA(row1.getCell(6).getStringCellValue());
detailed.setFirstInstance(row1.getCell(7).getStringCellValue());
detailed.setPreliminaryResults(row1.getCell(8).getStringCellValue());
detailed.setReasonsForFirstInstance(row1.getCell(9).getStringCellValue());
detailed.setTimeOfInitialExaminationAndStorage(row1.getCell(10).getStringCellValue());
detailed.setInitialAuditTime(row1.getCell(11).getStringCellValue());
detailed.setShenheshichang(Double.valueOf(row1.getCell(12).getStringCellValue()));
detailed.setTimeoutStatus(row1.getCell(13).getStringCellValue());
detailed.setQualityInspectionResults(row1.getCell(14).getStringCellValue());
detailed.setQualityInspectionReasons(row1.getCell(15).getStringCellValue());
detailed.setQualificationStatus(row1.getCell(16).getStringCellValue());
if (detailed != null) {
// 把对象放到集合里
detaileds.add(detailed);
}
}
// 返回集合
return detaileds;
}
}
- Controller层。
import com.iyunfish.tongcheng.domain.Detailed;
import com.iyunfish.tongcheng.service.ReadService;
import com.iyunfish.tongcheng.utils.ReadLocalFileUtils;
import com.iyunfish.tongcheng.utils.XlsxUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.io.IOException;
import java.util.List;
@RestController
public class ExcelReadController {
@Autowired
private ReadService readService;
@RequestMapping("/read/add")
// 参数path是存放.xlsx文件的路径
public void add(String path) throws IOException {
// 获取指定文件夹下的所有文件
List file = ReadLocalFileUtils.getFile(path);
// 循环遍历每个文件
for (int i = 0; i < file.size(); i++) {
// 获取excel中的数据 集合里放n个对象，对象里放一行excel信息
List read = XlsxUtils.read(file.get(i).toString());
// 循环向数据库添加信息
for (int a = 0; a < read.size(); a++) {
// 获取到当前行的信息
Detailed detailed = read.get(a);
// 添加
readService.addDetailed(detailed);
}
}
}
}
往后的接口实现类就不写了，没有逻辑，一直到xml文件
- ReadMapper.xml。添加的字段和
XXX根据自己的实际情况编写
INSERT INTO XXX (
`audit_date`,
`scene_id`,
`scene_name`,
`entityid`,
`housing_resources_id`,
`cityid`,
`firstInstanceOA`,
`firstInstance`,
`preliminary_results`,
`reasons_for_firstInstance`,
`time_ofInitial_examination_and_storage`,
`initial_audit_time`,
`shenheshichang`,
`timeout_status`,
`quality_inspection_results`,
`quality_inspection_reasons`,
`qualification_status`
)
VALUES
(#{read.auditDate}, #{read.sceneId}, #{read.sceneName}, #{read.entityid}, #{read.housingResourcesId}, #{read.cityid}, #{read.firstInstanceOA}, #{read.firstInstance}, #{read.preliminaryResults}, #{read.reasonsForFirstInstance}, #{read.timeOfInitialExaminationAndStorage}, #{read.initialAuditTime}, #{read.shenheshichang}, #{read.timeoutStatus}, #{read.qualityInspectionResults}, #{read.qualityInspectionReasons}, #{read.qualificationStatus})
这样写完了直接运行会有报错，因为请求参数是个路径，例如：D:\a。参数里面有特殊符号，需要在启动类添加一个@Bean就好了，详情看我的另一篇文章：https://www.jianshu.com/p/79e57e4f0f71
代码到此结束，给个关注！
