我希望电子邮件、电话号码和服务提供商这三个属性中的每一个都有四个文本输入框。每个输入都应该存储在不同的ArrayList对象的电子邮件、电话号码和服务提供商属性中。
我认为每个都将使用
这是我的代码：
这是我的控制器端点方法：
@GetMapping("/")
public String formMethod(Model model) {
ArrayList<User> users = new ArrayList<>(4);
model.addAttribute("users", users);
return "communicationForm";
}
这是我的用户类：
public class User {
String email;
String phoneNumber;
String serviceProvider;
String emailSubject;
String emailMessage;
String textSubject;
String textMessage;
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPhoneNumber() {
return phoneNumber;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
public String getServiceProvider() {
return serviceProvider;
}
public void setServiceProvider(String serviceProvider) {
this.serviceProvider = serviceProvider;
}
public String getEmailSubject() {
return emailSubject;
}
public void setEmailSubject(String emailSubject) {
this.emailSubject = emailSubject;
}
public String getEmailMessage() {
return emailMessage;
}
public void setEmailMessage(String emailMessage) {
this.emailMessage = emailMessage;
}
public String getTextSubject() {
return textSubject;
}
public void setTextSubject(String textSubject) {
this.textSubject = textSubject;
}
public String getTextMessage() {
return textMessage;
}
public void setTextMessage(String textMessage) {
this.textMessage = textMessage;
}
}
这是我的communicationForm.html文件

Thymeef不将List/ArrayList作为支持对象处理。。。因此，您必须创建另一个对象来容纳用户。
public class UserForm {
private List<User> users;
// getters and setters
}
对于model.addAttribute("form", userForm);，典型的形式如下：
<form action="#" th:action="@{/sendMessage}" th:object="${form}" method="post">
<th:block th:each="user, status: ${form.users}">
<p>
Email:
<input type="text" th:field="*{users[__${status.index}__].email}" />
</p>
</br>
</br>
</th:block>
控制器的方法看起来像：
@PostMapping("/sendMessage")
public String save(@ModelAttribute("form") UserForm form) {
