Spring 在按钮上单击“绑定列表”可将其绑定到文件夹中

我想要的是当我点击

id=addUnitCharge

按钮时，

id=proName

和

id=proAge

应该添加到

id=property\u type\u tbl

主体中。当我点击提交按钮时，所有值都应该分配给（

id=code

和

id=school

作为值和

id=property\u type\u tbl

值分配给

unitCharge

列表）

这是我的班

public class PlAccount{

    private String code;
    private String school;
    private List<UnitCharge> unitCharge;

    //Getters and Setters
}

我的控制器类

@GetMapping(path = {"/product/add")
public String index(Model model) {
   model.addAttribute("type", PlAccount.builder().build());
   return "/loan/product/add";
}

@PostMapping("/coopmis/waterTariff/product/add")
public String save(@Valid PlAccount plAccount, BindingResult result){
     plAccountService.savePlAccount(plAccount);
}

我的html

<form method="post" action="/product/add" th:object="${type}">

    <input type="number" id="code" class="form-control" th:name="code">
    <input type="number" id="school" class="form-control" th:name="school">

    //On button click below Items should add to `property_type_tbl` table.
