Spring-Boot + Spring-MVC + Thymeleaf + Apache Tiles

Question

Spring-Boot + Spring-MVC + Thymeleaf + Apache Tiles

Mic*_*ner 4 spring-mvc apache-tiles thymeleaf spring-boot spring-java-config

我已经有一个带有apache tile和thymeleaf的客户端模块，效果很好。我想将其转换为spring-boot，并希望逐步进行，但是我真的坚持使用它。我不想改变太多，当有人可以告诉我，我应该首先做什么并使其运行时，我会喜欢的。我已经尝试过在javaConfig中编写servlet，但是我也陷入了困境。也许有人可以帮我。如果需要更多信息，请随时询问。

另一个问题是，我需要从xml更改为javaconfig吗？我更喜欢最简单的方法。但是，一旦我将spring-starter依赖项添加到pom中，应用程序就不再起作用。

我知道了，希望对其他有类似问题的开发人员有所帮助。

在POM中，我删除了所有Spring-Dependencies，而仅使用Spring-Starter-Dependencies，如以下代码片段所示：

我的RestConfig类非常简单

我将所有html文件或thymeleaf模板移至src / main / resources下的template-folder。同样在同一个文件夹中，您可以将所有客户端资源（如图像，js和css）放在静态文件夹下。文件夹static和template是关键字，由Spring-Boot自动找到。application.properties中没有特殊配置，百里香和apache瓷砖需要这些配置。

项目结构

====

由于您的应用程序能够找到资源，因此可以如下配置路径：

<link rel="stylesheet" type="text/css" media="screen, projection" 
          href="/static/css/bootstrap.css" 
          th:href="@{/css/bootstrap.css}" />

<link rel="stylesheet" type="text/css" media="screen, projection" 
          href="/static/css/bootstrap-responsive.css" 
          th:href="@{/css/bootstrap-responsive.css}" />

如果这对您有帮助，请毫不犹豫地投票;-)。如果您需要更多信息，请发表评论，我将在几天内尝试回答。

好的，到目前为止，它仅在Eclipse下有效。当我执行可执行jar时，仍然出现错误。也许有人想帮助;-)

我的JAR的结构如下：

在此处输入图片说明

======

解：

我不知道为什么，但是另外我还必须修复模板的url路径，在Eclipse中它的工作原理与之类似，但不能作为可执行jar。为了使其在两种环境中都能运行，我必须修复所有如下所示的模板url，并对属性值进行特殊检查：

之前：

<definition name="home" extends="standard1ColLayout">
    <put-attribute name="title" value="/home/title :: content" type="thymeleaf" />
    <put-attribute name="body" value="/home/body :: content" type="thymeleaf" />
</definition>

后：

<definition name="home" extends="standard1ColLayout">
    <put-attribute name="title" value="./home/title :: content" type="thymeleaf" />
    <put-attribute name="body" value="./home/body :: content" type="thymeleaf" />
</definition>

最终，它可以在Eclipse下作为可执行jar起作用。从正常的Spring-Project转换为Spring-Boot Project并不是一件容易的事，我希望它能对其他开发人员有所帮助，并且希望该帖子值得投票。;-)
