Creating and Editing in Spring Framework

I recently started learning Spring from the Thymeleaf template engine for displaying the data. However, I have been facing some problems that I can not solve:

At the time of editing the Star Wars Movie entity, I can not retrieve the "ReleaseDate" field and set it to the date input of the form. When I change the input type to text, this particular data ends up being displayed, but I would like this to be done in a date input (which is most appropriate).

When I submit the "movieForm" form, both in the creation and editing of a movie, there is also a conversion problem in the "ReleaseDate" field. Spring points out that there is incompatibility between the type String (sent from the form) and the type Date (related to the database). How could I resolve this conversion problem?

This problem is related to the others, and it is also a mistake when submitting the "movieForm" form. I can not save the uploaded data, neither in the authoring operation, nor in the editing. I think it's some mistake I made in the Conversion classes (inside the package converters), but I've been looking for it for days and I can not figure it out.

Problem with accentuation when exporting data from Sql Server to Excel TXT File Manipulation Using Python

Lucas, regarding your item 1 dataRelease:

You can use the DateTimeFormat annotation to enter a mask in your model class. Already in your html when using thymeleaf you can use the mask defined in the template.

Note to place in Template:

@DateTimeFormat(pattern = "dd/MM/yyyy HH:mm:ss")

How to use the mask in html:

th:field="*{{releaseDate}}"

This should also resolve item 2.

A good practice is to use the annotation in the template as well as the annotation to determine the date type of the attribute.

@Temporal(TemporalType.TIMESTAMP)

These minor adjustments should solve your problem.
