Question

你好，我现在面临一个问题 - 好几天 - 我需要保存一个带有select / option的表单，该表单包含对另一个类的引用......但是当控制器试图保存它时失败。控制台没有显示任何内容......任何提示？白标错误页面

for (i = 0;i < dim;i++)
    free(&words[i]);

表格cadastro.html

This application has no explicit mapping for /error, so you are seeing this as a fallback.

Answer 1

尝试

    <select  id="select-medico-consulta" th:field="*{medico.id}">
        <option th:each="medicoEntry : ${medicos}" th:value="${medicoEntry.id}"
                    th:text="${medicoEntry.nome}" ></option>
    </select>

springboot + thymeelaf使用select和object处理表单
