Thymeleaf:按字段的验证错误 [英] Thymeleaf: validation error by field

问题描述

使用Thymeleaf + Spring和表单验证，我想在该字段旁边显示与该字段相关的错误.

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'"/>

如果该字段有错误，则确实应用错误"类.但是，有没有一种简便的方法可以显示字段的验证错误?

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?

推荐答案

使用以下代码显示错误:

Use this code to display error:

<p class="alert alert-danger" th:if="${#fields.hasErrors('companyName')}" th:errors="*{companyName}"></p>
