Spring MVC / Thymeleaf-如何使用一个输入字段插入两个不同的表？

Question

I have an input field for first name:

<input th:field="*{fleet.firstName}" class="signup1" type="text" id="fname" name="fname" autofocus="" required=""/>

I have two tables/objects 'fleet' and 'service.' How can I do that if thymeleaf only allows me to use one object per input field?

I tried two input th:field, but it didn't work. Like:

<input th:field="*{fleet.firstName}" th:field="*{service.firstName}" class="signup1" type="text" id="fname" name="fname" autofocus="" required=""/>

Answer 1

I think this is not possible. You could create a DTO object for Thymeleaf with the union of the fields that you are trying to see in the web side. Then, separate this into database tables in you Service tier.

Something like:

Option 1: WITHOUT th:object

<form th:action="@{/destination}">
      <input type="text" th:value="${service.firstName}" name="service.firstName"/>
      <input type="text" th:value="${fleet.firstName}" name="fleet.firstName"/>
      <button type="submit">Go</button>
</form>

Option 2:

web

<form th:action="@{/destination}" th:object="${myThymeleafFormObject}">

public class ThymeleafForm {

    private String fleetFirstName;
    private String serviceFirstName;

    ...

}

Service

public class MyService {

    // To avoid complexity maps the ThymeleafForm in different JPA entities 
    // Logic and repository calls
}

Repositories

public class FleetServiceRepositoryJPA {    
    //Database operations for fleet table
}

public class ServiceRepositoryJPA { 
    //Database operations for service table
}
