private void deleteMarkedCertificates() { log.warn("Deletes the certificate marked for deletion from the database"); List<CustomDomainCert> certsToDelete = customDomainCertRepository.findByDeleteFlag(true); customDomainCertRepository.deleteAll(certsToDelete); }需要加事务吗

根据这段代码，需要在方法上加上事务注解，确保该方法在执行过程中具有事务性。

可以使用Spring框架提供的@Transactional注解，在方法上添加该注解即可。例如：

@Transactional
private void deleteMarkedCertificates() {
    log.warn("Deletes the certificate marked for deletion from the database");
    List<CustomDomainCert> certsToDelete = customDomainCertRepository.findByDeleteFlag(true);
    customDomainCertRepository.deleteAll(certsToDelete);
}

这样添加事务注解后，当该方法执行时，会自动开启一个事务，方法执行结束后，事务会自动提交或回滚。这样可以保证数据库操作的一致性和可靠性。

可以考虑使用Java8的stream API来简化代码：

List<String> stringList = ExcelUtil.excelToShopIdList1(inputStream);
if (CollectionUtils.isEmpty(stringList)) {
    return warn("无数据");
}
List<EquDeviceTslProperty> excelResult = stringList.stream()
        .map(ar -> JSON.parseObject(ar, EquDeviceTslProperty.class))
        .collect(Collectors.toList());
String deviceCode = excelResult.get(0).getDeviceCode();
List<EquDeviceTslProperty> equDeviceTslProperties = equDeviceTslPropertyService.selectEquDeviceTslPropertyList(new EquDeviceTslProperty().setDeviceCode(deviceCode));
Map<String, List<EquDeviceTslProperty>> listMap = equDeviceTslProperties.stream().collect(Collectors.groupingBy(EquDeviceTslProperty::getPropertyId));
List<EquDeviceTslProperty> saveList = excelResult.stream()
        .filter(ar -> CollectionUtils.isEmpty(listMap.get(ar.getPropertyId())))
        .collect(Collectors.toList());
listMap.forEach((propertyId, properties) -> {
    excelResult.stream()
            .filter(ar -> propertyId.equals(ar.getPropertyId()))
            .findFirst()
            .ifPresent(ar -> {
                EquDeviceTslProperty property = properties.get(0);
                property.setValueType(ar.getValueType())
                        .setSortsIndex(ar.getSortsIndex())
                        .setPropertyName(ar.getPropertyName());
                equDeviceTslPropertyService.updateEquDeviceTslProperty(property);
            });
});
equDeviceTslPropertyService.batchInsert(saveList);

这样可以更清晰地表达出代码的逻辑，并且减少了一些不必要的中间变量的使用。

这个警告通常是由于组件或元素的 VNode 类型未定义而引起的。VNode 是 Vue 中的虚拟节点，它用于描述 DOM 节点的属性、样式、事件等信息。

可能的原因包括：

1. 组件或元素的名称拼写错误，导致 Vue 无法解析该组件或元素。
2. 组件或元素的文件未正确导入或注册，导致 Vue 找不到该组件或元素。
3. 组件或元素的模板中使用了未定义的变量或方法，导致 Vue 无法正确解析该模板。

您可以通过检查组件或元素的名称、文件路径和模板代码，以及确保组件或元素已正确导入和注册，来解决这个警告。如果问题仍然存在，请提供更多代码和信息以便更好地帮助您。
