public class ReservationForm {
    @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm")
    private LocalDateTime date;

    public ReservationForm(LocalDateTime date) {
        this.date = LocalDateTime.now();
    }

}
what i want: datepicker sends ajax request on changing the date to reload the displayed data, but when i change the date an error is thrown. demo project to showcase my problem: https://github.com/DragonCat4012/web-thymeleaf

Have you tried parsing your string using 
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm");
Date date = formatter.parse("2023-11-29T11:20:17.719199");
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm");
Date date = formatter.parse("2023-11-29T11:20:17.719199");
I have a feeling this won't work because the string looks sketchy in regards to the format pattern (I sadly can't try it rn)

Your ReservationForm specifies a datetime pattern in @DateTimeFormat decorator I doubt your pattern would work considering "2023-11-29T11:20:17.719199" as possible input

the correct format would be something along the lines of yyyy-MM-dd'T'HH:mm:ss.SSSSSS 
public class ReservationForm {
    @DateTimeFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSSSS")
    private LocalDateTime date;

    public ReservationForm(LocalDateTime date) {
        this.date = LocalDateTime.now();
    }

    public LocalDateTime getDate() {
        return date;
    }

    public void setDate(LocalDateTime date) {
        this.date = date;
    }

}
public class ReservationForm {
    @DateTimeFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSSSS")
    private LocalDateTime date;

    public ReservationForm(LocalDateTime date) {
        this.date = LocalDateTime.now();
    }

    public LocalDateTime getDate() {
        return date;
    }

    public void setDate(LocalDateTime date) {
        this.date = date;
    }

}
@' .•` KIΛ.RΛR ’•. ' that should at least make it parse correctly
