SpringBoot Merge

I'm using Spring Full, with Thymeleaf and SpringBoot, but my question is about SpringData, after implementing the interface to make use of the methods Spring makes available in the repository, when I created the Service, I did not find a method that would update .

I have read in some places that .save does the update as well, but in my case, this does not work, it is passed to register a client with id null, so, when registering, generates a new client and does not update , but it generates a new record.

Note: everything else works except the update.

My registration view:

Radio enable field, checked from bank How together did these two select?

score 1 · Accepted Answer

For the save method to do the merge of the object, it needs to know what the id is.

In case of an update, I recommend putting a hidden field containing the id, like this:

<input type="hidden" th:field="*{id}" />

When executing the request Spring will verify that the id already exists and will merge the data
