问题 I'm working on an authentication feature and have run into an issue with persisting the data from the entity class. I'm able to access the password_hash and the username from the data transfer object but am not able to see the email, firstName, lastName, or phoneNumber from the User class in the database.

问题 Using Thymeleaf + Spring and form validation, I want to display errors that are related to a field next to this field. <input type="text" th:field="*{companyName}" class="form-control" placeholder="Code client" th:errorClass="'error'"/> If the field has an error, the class "error" is applied indeed. But is there an easy way to display also the validation error of the field? 回答1: Use this code to display error: <p class="alert alert-danger" th:if="${#fields.hasErrors('companyName')}" th:errors
