Thymeleaf-JAVA中的传递模型

Question

I am trying to create a simple webpage, in which animals have some properties (like name, animalType, and balance) using Thymeleaf. However, I've been suffering from the proper syntax.

My Java code is:

   @GetMapping("/multipleaccounts")
   public String multiple(Model model) {
   List bankAccounts = new ArrayList<>();
   model.addAttribute("account", bankAccounts);
   return "multiple";
   }

The problematic part of my thymeleaf code at the /multipleaccounts endpoint:

<div th:each="element : ${account}" th:object="${element}">
    <p th:text="|My name is *{name}|"></p>
    <p th:text="|My balance is *{balance}|"></p>
    <p th:text="|My type is *{animalType}|"></p>
</div>`

Answer 1

I recommend you not use the raw types but rather List<Account> or similar.

To iterate the List in Thymeleaf template, please see the Baeldung's webpage where is this issue properly explained.

In a nutshell, the correct notation with the string concatenation is the following:

<div th:each="a: ${account}">
    <p th:text="'|My name is ' + ${a.name} + '|'"></p>
    <p th:text="'|My balance is ' + ${a.balance} + '|'"></p>
     <p th:text="|My type is ' + ${a.animalType} + '|'"></p>
</div>

By the way, are you sure that each account has animalType ?

Answer 2

This will helps you:

<div th:each="element : ${account}">
    <p th:text="'|My name is ' + ${element.name} + '|'"></p>
    <p th:text="'|My balance is ' + ${element.balance} + '|'"></p>
    <p th:text="'|My type is ' + ${element.animalType} + '|'"></p>
</div>
