在表单中添加是微不足道的:
<form th:action="|#{group/save}/${id}|" th:object="${groupForm}" method="post" class="col m8 s8 offset-m2">
<div class="row">
<div class="input-field">
<input th:field="${groupForm.name}" id="name" type="text" required="required"/>
<label for="name">Nazwa:</label>
</div>
</div>
<div class="row">
<button class="btn-success" type="submit" name="save">Wyślij<i class="mdi-content-send right"></i></button>
</div>
</form>
但我们假设groupForm有客户列表
public class Customer{
private long id;
private String firstName;
private String lastName;
private String nick;
}
如何将5个客户添加到班级组的列表中?我想在一个请求中实现。

假设您的Group类看起来像这样:
public class Group {
private List<Customer> customers;
}
试试这个:
<input th:field="*{customers[0].name}" type="text" required="required"/>
<input th:field="*{customers[1].name}" type="text" required="required"/>
<input th:field="*{customers[2].name}" type="text" required="required"/>
<input th:field="*{customers[3].name}" type="text" required="required"/>
<input th:field="*{customers[4].name}" type="text" required="required"/>
