Java 百里香验证

我正在学习thymeleaf验证部分，我得到了如下错误

        <div class="form50">
            <label for="contact.emailAddress"><span th:text="#{contact.email}">Email</span></label>
             <span class="error" th:if="${#fields.hasErrors('email')}" th:errors="email"></span>
            <input type="email" th:field="*{email}" class="field50" th:classappend="${#fields.hasErrors('email')}? 'fieldError'" />
        </div>

        <div class="form50">
            <label for="customer.firstName"><span th:text="#{contact.jobtitle}">Job Title</span></label>
            <span class="error" th:if="${#fields.hasErrors('jobtitle')}" th:errors="*{jobtitle}"></span>
            <input type="text" th:field="*{jobtitle}" class="field50" th:classappend="${#fields.hasErrors('name')}? 'fieldError'" />
        </div>

        <div class="login_register">
            <input class="register_button big red" type="submit" th:value="#{contact.contact}"/>
        </div>

    </blc:form>

有什么问题我不能确定！！！！！！请帮助

问题如下

        <div class="form50">
            <label for="contact.emailAddress"><span th:text="#{contact.email}">Email</span></label>
             <span class="error" th:if="${#fields.hasErrors('email')}" th:errors="email"></span>
            <input type="email" th:field="*{email}" class="field50" th:classappend="${#fields.hasErrors('email')}? 'fieldError'" />
        </div>

        <div class="form50">
            <label for="customer.firstName"><span th:text="#{contact.jobtitle}">Job Title</span></label>
            <span class="error" th:if="${#fields.hasErrors('jobtitle')}" th:errors="*{jobtitle}"></span>
            <input type="text" th:field="*{jobtitle}" class="field50" th:classappend="${#fields.hasErrors('name')}? 'fieldError'" />
        </div>

        <div class="login_register">
            <input class="register_button big red" type="submit" th:value="#{contact.contact}"/>
        </div>

    </blc:form>

<span class="error" th:if="${#fields.hasErrors('email')}" th:errors="email"></span>

与下面代码中的这一行相同

        <div class="form50">
            <label for="contact.emailAddress"><span th:text="#{contact.email}">Email</span></label>
             <span class="error" th:if="${#fields.hasErrors('email')}" th:errors="email"></span>
            <input type="email" th:field="*{email}" class="field50" th:classappend="${#fields.hasErrors('email')}? 'fieldError'" />
        </div>

        <div class="form50">
            <label for="customer.firstName"><span th:text="#{contact.jobtitle}">Job Title</span></label>
            <span class="error" th:if="${#fields.hasErrors('jobtitle')}" th:errors="*{jobtitle}"></span>
            <input type="text" th:field="*{jobtitle}" class="field50" th:classappend="${#fields.hasErrors('name')}? 'fieldError'" />
        </div>

        <div class="login_register">
            <input class="register_button big red" type="submit" th:value="#{contact.contact}"/>
        </div>

    </blc:form>

<span class="error" th:if="${#fields.hasErrors('jobtitle')}" th:errors="*{jobtitle}"></span>

stacktrace中更有趣的消息更深。你能发布完整的吗？你能先验证一下你的代码吗？看起来你的表单元素有点混淆了。并发布整个表单元素。。。
