Spring4 Webflow Thymeleaf2 Tiles Ajax: все работает, кроме

Question

Моя конфигурация плиток и Ajax Spring4 Thymeleaf2 работает, кроме самого последнего шага. Моя HTML-страница не обновляется. Я знаю, что метод вызывается, и результат возвращается из моего метода обслуживания. Я думаю, что моя ошибка заключается в том, как я отношусь к "идентификатору" в плитке helloworld.

Я покажу всю свою конфигурацию, так как в Интернете есть несколько примеров конфигурации xml, и один из них неправильный.

Помощь на последнем этапе будет высоко ценится.

Ключевые части конфигурации:

Понял!

Плитки с песочницей Thymeleaf были очень полезными, как и этот пост (нижняя часть темы)

Я сделал несколько изменений.

1. Я сделал фрагмент ajax отдельным html-файлом, hw4.html. ПРИМЕЧАНИЕ: я называю дату дважды в этом тесте. Один раз непосредственно через тимелист (который подтверждает обновление плитки) и один раз из боба (который подтверждает, что бин находится в области действия и обновляется). Таким образом я мог подтвердить, что это не было проблемой с моим бобом или определением объема.

<div id="data"> <h3 th:text="${#dates.createNow()}"></h3>
 <span  th:text="${mydate}? ${mydate.date}">
  the date goes here</span></div>
 

Также обратите внимание, что нет th: фрагмент или плитки: фрагмент. Это больше не нужно.

Views.xml выглядит так:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE tiles-definitions PUBLIC
 "-//Apache Software Foundation//DTD Tiles Configuration 2.1//EN"
 "http://tiles.apache.org/dtds/tiles-config_3_0.dtd">
 
<tiles-definitions>
 
 
  <!-- If just using tiles view resolver all pages must be defined in view regardless of whether or not they use tiles
  The path to the tiles is the path over and ablve the path specified in templateResolver configuration. Hence since template configuration
  specifies WEB-INF/html and since there is a single view.xml and all html files (templates and fragments) in the html folder, no further 
  path specification is required in this case. Webflow will be looking for the definition name as the "to" value of a transition -->
  <definition name="hellotl" template="hellotl" templateType="thymeleaf"/>
  <definition name="hellotlv1" template="hellotlv1" templateType="thymeleaf"/>
  
  
      <!-- standard.html is a template. hw and hw2 are tiles inserted into the template. Note there is no need to specify a suffix .html here -->
  <definition name="standard" template="standard" templateType="thymeleaf">
  <put-attribute name="testa" value="hw :: content" type="thymeleaf"/> 
  <put-attribute name="testb" value="hw2 :: test"  type="thymeleaf"/>
  <put-attribute name="helloworld" value="hw :: helloworld"  type="thymeleaf"/> 
  </definition>
 
 <!--  standardext is where we attempt an ajax call.  -->
 <definition name="standardext" extends="standard" templateType="thymeleaf">
  <put-attribute name="testa" value="hw3 :: content" type="thymeleaf"/>  
  <put-attribute name="testb" value="hw2 :: blank" type="thymeleaf"/> 
    <put-attribute name="helloworld" value="hw4"  type="thymeleaf"/> 
 </definition>

 
</tiles-definitions>

Шаблон плиток должен использовать плитки: заменить

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" 
      xmlns:th="http://www.thymeleaf.org"
      xmlns:tiles="http://www.thymeleaf.org"
      xmlns:sec="http://www.thymeleaf.org"
      lang="en">
     
      
<head>

<title>test layout</title>


</head>

<body >

<div tiles:include="testa">dodododo</div>

  This text appears everywhere
<div tiles:include="testb">kkkkkkk</div>

<div tiles:replace="helloworld">hello world</div>  



</body>


</html>

Форма плитки практически не изменилась:

<div tiles:fragment="content">

  <script type="text/javascript" th:src="@{/resources/dojo/dojo.js}"></script>
  <script type="text/javascript" th:src="@{/resources/spring/Spring.js}"></script>
  <script type="text/javascript"
   th:src="@{/resources/spring/Spring-Dojo.js}"></script>

  <form id="triggerform" method="post" action="">
   <input type="submit" id="helloWorld" name="_eventId_doHelloWorld"
    value="Update now!" />
  </form>

  <script type="text/javascript">
   Spring.addDecoration(new Spring.AjaxEventDecoration({
    formId : 'triggerform',
    elementId : 'helloWorld',
    event : 'onclick'
   }));
  </script>
  
  
 </div>

Остальное почти так же, как в вопросе. Я не вносил изменения в контекст приложения.

Итак, это работает. У меня ушло около недели, чтобы проработать тимелист и аякс. Надеюсь, что этот пост будет намного проще для других.

Я должен подчеркнуть, что это усилия новичка. Эксперты могут предложить предлагаемые улучшения или ошибки в этом посте
