Why updating items will trigger com.ctrip.framework.apollo.common.entity.BaseEntity#setDeleted ?

[nobodyiam]

It's because of the statement - BeanUtils.copyEntityProperties(item, managedItem);.

apollo/apollo-biz/src/main/java/com/ctrip/framework/apollo/biz/service/ItemService.java

Lines 186 to 197 in 63c16c1

	@Transactional
	public Item update(Item item) {
	checkItemValueLength(item.getNamespaceId(), item.getValue());
	Item managedItem = itemRepository.findById(item.getId()).orElse(null);
	BeanUtils.copyEntityProperties(item, managedItem);
	managedItem = itemRepository.save(managedItem);
	auditService.audit(Item.class.getSimpleName(), managedItem.getId(), Audit.OP.UPDATE,
	managedItem.getDataChangeLastModifiedBy());
	return managedItem;
