如何在Thymeleaf上对动态数据使用多个“组件”(文件)?

标签: java html model-view-controller thymeleaf

我正在建立一个新的网站,我想拥有多个文件来存储可重复使用的组件(页眉,页脚,,上的常用导入,脚本等)。我还希望每个布局都有文件(结合我定义的组件),例如“主应用程序”,“全屏仪表板”等。 最后,我想创建仅包含所需内容的页面,然后将其插入我选择的布局中。

类似这样的内容:Diagram of files

我看过this question,但这要求我以内容为参数调用java布局,而不是在内容上定义要使用的布局。

我还考虑过仅将“布局”用作模板,然后将+粘贴并粘贴到新的“内容”文件中,然后将占位符编辑掉。

这是一个示例控制器:

    @View("ticketing/home")
    @Get("/")
    public HttpResponse home() {
        final Map<String, Object> resultMap = new HashMap<>();

        resultMap.put("requests", ticketingClient.getSummaryRequests()); //Returns a list of tickets to be displayed.
        return HttpResponse.ok(resultMap); //Maps the resultMap variable to the ticketing/home thymeleaf template
    }

这就是我想要的内容文件结构化的方式:

<html>
    <head>
        <title>Tickets</title>
    </head>
<body>
    <div>
        <p>My Content is here!</p>
        <img src="wow.jpeg">
    </div>
</body>
</html>

这就是我现在的布局:

<html xmlns:th="http://www.thymeleaf.org">
<head>
    <title>Application Layout</title>
    <th:block th:include="./fragments/head.html :: imports"></th:block>
</head>
<body>
    <div id="wrapper">
        <!-- Sidebar Menu -->
        <div th:replace="./fragments/sidebar.html :: sidebar"></div>
        <div id="page-wrapper" class="gray-bg">
            <!-- Navigation Menu -->
            <div th:replace="./fragments/topbar.html :: topbar"></div>
            <!-- Page Header -->
            <div th:replace="./fragments/pageheader.html :: pageheader"></div>
            <!-- Main Content -->
            <div class="wrapper wrapper-content animated fadeInUp" th:fragment="content">
                <div class="row">
                    <div class="col-lg-12">
                        <div class="wrapper wrapper-content">
                            <p>Content here</p>
                        </div>
                    </div>
                </div>
            </div>
        </div>
    </div>
    <div th:replace="./fragments/footer.html :: footer"></div>
    <th:block th:replace="./fragments/scripts.html :: scripts"></th:block>
</body>
</html>

我希望能够使用相同的Java语法(带有批注)来使用我的视图。

相对于布局文件,我宁愿在内容文件中进行更多更改。

我找到了一个对我有用的答案:

我已经引用了this postthis other postthe post mentioned on the question

以下是一些代码: 组件:内容

<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>Content Wrapper</title>
</head>
<body>
    <div class="wrapper wrapper-content animated fadeInUp" th:fragment="content(content)">
        <!-- Main Content -->
        <div class="row">
            <div class="col-lg-12">
                <div class="wrapper wrapper-content">
                    <th:block th:replace="${content}"></th:block>
                </div>
            </div>
        </div>
    </div>
</body>
</html>

组件:pageheader

<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org" th:fragment="pageheader">
<head>
<title>Page Header</title>
</head>
<body>
    <div class="row wrapper border-bottom white-bg page-heading" th:fragment="pageheader(title)">
        <div class="col-sm-8 col-lg-9">
            <!-- Title -->
            <h2 th:replace="${title}">This is main title</h2>
            <th:block th:if="${breadcrumb}">
                <!-- Breadcrumb -->
                <ol class="breadcrumb" th:replace="${breadcrumb}">
                    <li class="breadcrumb-item"><a href="index.html">This is</a></li>
                    <li class="breadcrumb-item active"><strong>Breadcrumb</strong></li>
                </ol>
            </th:block>
        </div>
        <div class="col-sm-4 col-lg-3">
            <th:block th:if="${actions}">
                <!-- Main Action -->
                <div class="title-action btn-group" th:if="${actions}" th:replace="${actions}">
                    <a href="" class="btn btn-primary">Main Actions</a>
                    <a href="" class="btn btn-primary">Main Actions</a>
                </div>
            </th:block>
        </div>
    </div>
</body>
</html>

布局:应用布局

<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org" th:fragment="layout"> <!-- ${content} and ${title} are mandatory -->
<head>
<title th:replace="${title}">Application Layout</title>
<th:block th:include="./fragments/head.html :: imports"></th:block>
</head>
<body>
    <div id="wrapper">
        <!-- Sidebar Menu -->
        <div th:replace="./fragments/sidebar.html :: sidebar"></div>
        <div id="page-wrapper" class="gray-bg">
            <!-- Navigation Menu -->
            <div th:replace="./fragments/topbar.html :: topbar"></div>
            <!-- Page Header -->
            <div th:replace="./fragments/pageheader.html :: pageheader(title=${title},breadcrumb=${breadcrumb},actions=${actions})"></div>
            <!-- Main Content -->
            <div class="wrapper wrapper-content animated fadeInUp" th:replace="./fragments/content.html :: content(${content})"></div>
        </div>
    </div>
    <div th:replace="./fragments/footer.html :: footer"></div>
    <th:block th:replace="./fragments/scripts.html :: scripts"></th:block>
</body>
</html>

内容:票证

<!DOCTYPE html>
<html lang="en" th:replace="~{layout/applayout.html :: layout(title=~{::title},breadcrumb=~{::ol},content=~{::#main},scripts=~{::#scripts})}" xmlns:th="http://www.thymeleaf.org">
<head>
<title>Homepage</title>
</head>
<body>
    <ol class="breadcrumb">
        <li class="breadcrumb-item"><a href="index.html">Home</a></li>
        <li class="breadcrumb-item active"><strong>wow</strong></li>
    </ol>
    <div id="main">
        <div class="col">
            <p>WOW</p>
        </div>
        <div class="col">
            <p>WOW</p>
        </div>
        <div class="col">
            <p>WOW</p>
        </div>
    </div>
    <th:block id="scripts">
    </th:block>
</body>
</html>

这样,我可以在内容页面上具有可选参数,这些参数将分别由每个片段处理。
