EasyPOI导入多个sheet，既可更新又可新增，且从第二个sheet开始是根据第一个sheet内容的详情导入

1、第一张sheet的导入类
@Data
@ExcelTarget("PmAppServiceManageNewImportVO")
@EqualsAndHashCode(callSuper = false)
public class PmAppServiceManageNewImportVO extends ExcelVerifyInfo implements IExcelModel {/** 应用名称 */@Excel(name = "*应用名称", width = 18, orderNum = "1")@NotNullprivate String projectName;/** 应用负责人 */@Excel(name = "*应用负责人", width = 18, orderNum = "2")@NotNullprivate String applicationUser;/** 业务负责人 */@Excel(name = "*业务负责人", width = 18, orderNum = "3")@NotNullprivate String businessUser;/** 应用状态;1使用,2停用 */@Excel(name = "*应用状态", width = 18, orderNum = "4", replace = {"使用_1", "停用_2", "_null"}, addressList = true)@NotNullprivate Integer status;/** 环境;1正式,2测试,3开发) */@Excel(name = "*环境", width = 18, orderNum = "5", replace = {"开发_3", "测试_2", "正式_1", "_null"},addressList = true)@NotBlankprivate String environment;/** 管理员账号 */@Excel(name = "管理员账号", width = 18, orderNum = "6")private String adminAccount;/** 管理员密码 */@Excel(name = "管理员密码", width = 18, orderNum = "7")private String adminPassword;/** 备注 */@Excel(name = "备注", width = 18, orderNum = "8")private String remarks;@ExcelIgnoreprivate String errorMsg;
}1.1、第二张sheet导入类
@Data
@ExcelTarget("PmAppServiceManageDetailsImportVO")
@EqualsAndHashCode(callSuper = false)
public class PmAppServiceManageDetailsImportVO extends ExcelVerifyInfo implements IExcelModel {/** 服务名称 */@Excel(name = "*服务名称", width = 18, orderNum = "1")@NotBlankprivate String serviceName;/** 服务类型 */@Excel(name = "*服务类型", width = 18, orderNum = "2", replace = {"前端服务_1", "后端服务_2", "数据服务_3", "MQ服务_4", "附件服务_5", "通用服务_6", "外部服务_7"},addressList = true)@NotBlankprivate String serviceType;/** 运维负责人 */@Excel(name = "*运维负责人", width = 18, orderNum = "3")@NotNullprivate String operationUser;/** 开发负责人 */@Excel(name = "*开发负责人", width = 18, orderNum = "4")@NotNullprivate String developmentUser;/** 映射IP */@Excel(name = "映射IP", width = 18, orderNum = "5")private String mappingIp;/** 映射端口 */@Excel(name = "映射端口", width = 18, orderNum = "6")private String mappingPort;/** 内部IP地址 */@Excel(name = "*内部IP", width = 18, orderNum = "7")@NotBlankprivate String insideIp;/** 内部端口 */@Excel(name = "*内部端口", width = 18, orderNum = "8")@Pattern(regexp = "^[0-9]*$", message = "只能输入数字！")@NotBlankprivate String occupyPort;/** 超融合集群 */@Excel(name = "超融合集群", width = 18, orderNum = "9")private String hyperconvergedCluster;/** CPU用量 */@Excel(name = "CPU用量", width = 18, orderNum = "10")private String centralProcessingUnit;/** 内存用量 */@Excel(name = "内存用量", width = 18, orderNum = "11")private String internalStorage;/** 硬盘用量 */@Excel(name = "硬盘用量", width = 18, orderNum = "12")private String hardDiskSize;@ExcelIgnoreprivate String errorMsg;
}
1.2、注解解释
- @ExcelTarget：表示要导出的目标对象，作用在实体类上。
- @EqualsAndHashCode(callSuper = false):排除父类字段。
- @Data相当于@Getter @Setter @RequiredArgsConstructor @ToString @EqualsAndHashCode这5个注解的合集。
- @ExcelIgnore：标注在成员变量上，默认所有字段都会和excel去匹配，加了这个注解会忽略该字段。
- @Excel： 作用到filed上面,是对Excel一列的一个描述
- name：列名。
- width：列宽。
- orderNum：列的排序。如果不加，将根据实体类的顺序进行导出。
- needMerge：纵向合并单元格。用于含list中创建多个row。
- replace：值的替换。也就是excel单元格表现为下拉框。

2、配置设置
2.1、导入第一张sheet
ImportParams params1 = new ImportParams();// 读取第一张sheetparams1.setStartSheetIndex(0);params1.setSheetNum(1);//标题行2params1.setTitleRows(2);//表头1params1.setHeadRows(1);// 不需要保存params1.setNeedSave(false);//设置读取空值params1.setKeyIndex(null);// 开启验证params1.setNeedVerify(true);String message = "";//创建HSSFWorkbookWorkbook hssfWorkbook = new HSSFWorkbook();try (InputStream inputStream = file.getInputStream()){//easypoi导入，数据量不大ExcelImportResult<PmAppServiceManageNewImportVO> appServiceResult =ExcelImportUtil.importExcelMore(inputStream, PmAppServiceManageNewImportVO.class, params1);//创建空数组，用于导入内容的新增或者更新List<PmAppServiceManageNew> pmAppServiceManageNewAddList = new ArrayList<>();List<PmAppServiceManageNew> pmAppServiceManageNewUpdateList = new ArrayList<>();hssfWorkbook = appServiceResult.getWorkbook();//显示错误信息for (int i = 0; i < appServiceResult.getFailList().size(); i++){PmAppServiceManageNewImportVO excel = appServiceResult.getFailList().get(i);if (appServiceResult.getFailList().get(i).getErrorMsg() != null&& !"".equals(appServiceResult.getFailList().get(i).getErrorMsg())){message = message + "--> 第" + excel.getRowNum() + "行,"+ appServiceResult.getFailList().get(i).getErrorMsg();}}appServiceResult.getList().stream().forEach(appService -> {String projectName = appService.getProjectName();String environment = appService.getEnvironment();String applicationUser = appService.getApplicationUser();String businessUser = appService.getBusinessUser();// 应用名称-环境唯一PmAppServiceManageNew selectOne = pmAppServiceManageMapper.selectList(new LambdaQueryWrapper<PmAppServiceManageNew>().eq(PmAppServiceManageNew::getProjectName, projectName).eq(PmAppServiceManageNew::getEnvironment, environment).eq(PmAppServiceManageNew::getDelFlag, DelFlagEnum.NORMALL.getValue())).stream().findFirst().orElse(null);// 存入数据库PmAppServiceManageNew pmAppServiceManageNew = new PmAppServiceManageNew();pmAppServiceManageNew.setProjectName(appService.getProjectName());pmAppServiceManageNew.setApplicationUser(applicationUser);pmAppServiceManageNew.setBusinessUser(businessUser);pmAppServiceManageNew.setStatus(appService.getStatus());pmAppServiceManageNew.setEnvironment(appService.getEnvironment());pmAppServiceManageNew.setAdminAccount(appService.getAdminAccount());pmAppServiceManageNew.setAdminPassword(appService.getAdminPassword());pmAppServiceManageNew.setDelFlag(DelFlagEnum.NORMALL.getValue());pmAppServiceManageNew.setCreateBy(SecurityUtils.getUser().getId());pmAppServiceManageNew.setCreateTime(LocalDateTime.now());// 新增if (ObjectUtil.isNull(selectOne)){pmAppServiceManageNewAddList.add(pmAppServiceManageNew);}else{// 更新pmAppServiceManageNew.setId(selectOne.getId());pmAppServiceManageNew.setUpdateBy(SecurityUtils.getUser().getId());pmAppServiceManageNew.setUpdateTime(LocalDateTime.now());pmAppServiceManageNewUpdateList.add(pmAppServiceManageNew);}});if (ObjectUtil.isNotEmpty(pmAppServiceManageNewAddList)){saveBatch(pmAppServiceManageNewAddList);}if (ObjectUtil.isNotEmpty(pmAppServiceManageNewUpdateList)){updateBatchById(pmAppServiceManageNewUpdateList);}}
2.2、导入后面的sheet
// 导入后面的详情表for (int numSheet = 1; numSheet <= hssfWorkbook.getNumberOfSheets() - 1; numSheet++){//设置sheet的名称：projectName-environment String sheetName = hssfWorkbook.getSheetName(numSheet);if (!sheetName.contains("-")){throw new BizException("第" + numSheet + "个sheet命名不规范，请重新编辑！");}String[] split = sheetName.split("-");String projectName = split[0];String environment = "";switch (split[1]){case "正式":{environment = "1";break;}case "测试":{environment = "2";break;}case "开发":{environment = "3";break;}default:break;}// 校验sheetName对应的project是否存在PmAppServiceManageNew selectOne =pmAppServiceManageMapper.selectList(new LambdaQueryWrapper<PmAppServiceManageNew>().eq(PmAppServiceManageNew::getProjectName, projectName).eq(PmAppServiceManageNew::getEnvironment, environment).eq(PmAppServiceManageNew::getDelFlag, DelFlagEnum.NORMALL.getValue())).stream().findFirst().orElse(null);if (ObjectUtil.isNull(selectOne)){throw new BizException("应用:" + sheetName + "不存在,请先添加对应应用！");}ImportParams params2 = new ImportParams();// 读取第二个sheet到第一千个sheetparams2.setStartSheetIndex(numSheet);params2.setSheetNum(1);params2.setNeedSave(false);params2.setKeyIndex(null);params2.setNeedVerify(true);List<PmAppServiceManageDetails> pmAppServiceManageDetailsAddList = new ArrayList<>();List<PmAppServiceManageDetails> pmAppServiceManageDetailsUpdateList = new ArrayList<>();try (InputStream inputStream1 = file.getInputStream()){ExcelImportResult<PmAppServiceManageDetailsImportVO> appServiceDetailsResult =ExcelImportUtil.importExcelMore(inputStream1, PmAppServiceManageDetailsImportVO.class, params2);//显示报错信息for (int i = 0;

2.3、最后导入失败，抛出异常，导入成功返回信息
try{//代码块
} catch (Exception e){throw new BizException(e.getMessage());}return R.ok("导入成功！");
