Spring Boot，Thymeleaf表单错误=>我想从表中选择编辑行

Question

我想在另一个html页面中编辑表格的一行。我有一个初学者与thymeleaf和Spring MVC...

profileSall.html

但是，我有这个错误：org.thymeleaf.exceptions.templateProcessingException：执行处理器“org.thymeleaf.spring5.processor.springInputRadioFieldTagProcessor”（模板：“profilsall”-第39行，第26栏）时出错....

原因：java.lang.IllegalStateException：bean名称'profil'的BindingResult和普通目标对象都不能作为请求属性使用

profilsall.html：

<form th:action="@{/profiles/update}" th:object="${profil}" method="POST">
    <table border="1">
        <thead>
            <tr> 
                <th>Select</th> 
                <th>UID</th>
                <th>SIP</th>
                <th>enterpriseVoiceEnabled</th>
                <th>voicePolicy</th>
                <th>dialPlan</th>
                <th>samAccountName</th>
                <th>exUmEnabled</th>
                <th>exchUser</th>
                <th>objectClass</th>
                <th>statusProfile</th>
            </tr>
        </thead>
        <tbody>
            <tr th:if="${skypeProfiles.empty}">
                <td colspan="2"> No skype profile available </td>
            <tr th:each="skypeProfile, profile:${skypeProfiles}">
                <td>
                    <input type="radio" th:field="*{profile}" th:value="${profile}" />
                </td>
                <td th:text=${skypeProfile.collaboraterId}>UID</td>
                <td th:text=${skypeProfile.SIP}>SIP</td>
                <td th:text=${skypeProfile.enterpriseVoiceEnabled}>enterpriseVoiceEnabled</td>
                <td th:text=${skypeProfile.voicePolicy}>voicePolicy</td>
                <td th:text=${skypeProfile.dialPlan}>dialPlan</td>
                <td th:text=${skypeProfile.samAccountName}>samAccountName</td>
                <td th:text=${skypeProfile.exUmEnabled}>exUmEnabled</td>
                <td th:text=${skypeProfile.exchUser}>exchUser</td>
                <td th:text=${skypeProfile.objectClass}>objectClass</td>
                <td th:text=${skypeProfile.statusProfile}>statusProfile</td>
            </tr>   
        </tbody>
    </table>
    <button type="submit" value ="Edit">Edit</button>
</form>

控制器：

@PostMapping("profiles/update")
public String profilesUpdate(@ModelAttribute("profil") SkypeProfileSearchBean skypeProfile) {
    
    System.out.print("skypeProfile id "+skypeProfile.getCollaboraterId());
    return "profilsUpdate";
}

<input type="radio" th:field="*{profile}" th:value="${profile}" />

您不需要有两个skypeProfiles实例来在object中使用一个实例并显示一个实例。只要有一个实例就足够了。参见https://www.baeldung.com/spring-boot-crud-thymeleaf

将替换为

和一起使用
