今天给宝子带来一套多sheet页导入的模板，话不多说直接上代码

   String localFilePath = "file.xlsx";JSONObject jsonObject = JSON.parseObject(file);String useFile = jsonObject.getString("file");useFile=useFile.replace("\\\\","/");System.out.println("222222"+useFile);if (useFile.startsWith("http")||useFile.startsWith("https")||useFile.startsWith("ftp")){System.out.println("11111111111111111111");URL url = new URL(useFile);// 打开远程文件的输入流BufferedInputStream inputStream = new BufferedInputStream(url.openStream());// 创建本地文件的输出流FileOutputStream outputStream = new FileOutputStream(localFilePath);// 从输入流读取数据并写入输出流byte[] buffer = new byte[1024];int bytesRead;while ((bytesRead = inputStream.read(buffer, 0, 1024)) != -1) {outputStream.write(buffer, 0, bytesRead);}// 关闭流inputStream.close();outputStream.close();}else {localFilePath=useFile;}EasyExcel.read(localFilePath, CustomerExcel.class,new CustomerExcelListener()).sheet(0).doRead();EasyExcel.read(localFilePath, CustomerBankExcel.class,new CustomerBankExcelListener()).sheet(0).doRead();EasyExcel.read(localFilePath, CustomerAddressExcel.class,new CustomerAddressExcelListener()).sheet(0).doRead();EasyExcel.read(localFilePath, CustomerCreditExcel.class,new CustomerCreditExcelListener()).sheet(0).doRead();EasyExcel.read(localFilePath, CustomerSaleExcel.class,new CustomerSaleExcelListener()).sheet(0).doRead();List<Customer> customers = CustomerExcelListener.list;List<CustomerBank> customerBanks = CustomerBankExcelListener.list;List<CustomerAddress> customerAddresses = CustomerAddressExcelListener.list;List<CustomerCredit> customerCredits = CustomerCreditExcelListener.list;List<CustomerSale> customerSales = CustomerSaleExcelListener.list;customers.stream().forEach(customer -> {LambdaQueryWrapper<Customer> eq = new QueryWrapper<Customer>().lambda().eq(Customer::getCode, customer.getCode());Customer one = customerService.getOne(eq);if (one!=null){BeanUtils.copyProperties(customer,one);customerService.updateById(one);}else {customerService.save(customer);}});customerBanks.stream().forEach(customerBank -> {LambdaQueryWrapper<CustomerBank> eq = new QueryWrapper<CustomerBank>().lambda().eq(CustomerBank::getCustomerCode, customerBank.getCustomerCode());CustomerBank one = customerBankService.getOne(eq);if (one!=null){BeanUtils.copyProperties(customerBank,one);customerBankService.updateById(one);}else {customerBankService.save(customerBank);}});customerAddresses.stream().forEach(customerAddress -> {LambdaQueryWrapper<CustomerAddress> eq = new QueryWrapper<CustomerAddress>().lambda().eq(CustomerAddress::getCustomerCode, customerAddress.getCustomerCode());CustomerAddress one = customerAddressService.getOne(eq);if (one!=null){BeanUtils.copyProperties(customerAddress,one);customerAddressService.updateById(one);}else {customerAddressService.save(customerAddress);}});customerCredits.stream().forEach(customerCredit -> {LambdaQueryWrapper<CustomerCredit> eq = new QueryWrapper<CustomerCredit>().lambda().eq(CustomerCredit::getCustomerCode, customerCredit.getCustomerCode());CustomerCredit one = customerCreditService.getOne(eq);if (one!=null){BeanUtils.copyProperties(customerCredit,one);customerCreditService.updateById(one);}else {customerCreditService.save(customerCredit);}});customerSales.stream().forEach(customerSale -> {LambdaQueryWrapper<CustomerSale> eq = new QueryWrapper<CustomerSale>().lambda().eq(CustomerSale::getCustomerCode, customerSale.getCustomerCode());CustomerSale one = customerSaleService.getOne(eq);if (one!=null){BeanUtils.copyProperties(customerSale,one);customerSaleService.updateById(one);}else {customerSaleService.save(customerSale);}});customerCredits.clear();customers.clear();customerSales.clear();customerAddresses.clear();customerBanks.clear();return JsonResponse.ok();
