如何避免在 Spring MVC 中硬链接前端资源
我是 Spring MVC 的新手，有使用 PHP MVC 框架和 ROR 的经验。我很难找到适当的方法来组织前端资产并将其包含到视图模板中。
这是 Roo 为默认样式表生成的默认代码：
<spring:theme code="styleSheet" var="roo_css"/>
<spring:url value="/${roo_css}" var="roo_css_url"/>
<spring:url value="/static/images/favicon.ico" var="favicon" />
<link rel="stylesheet" type="text/css" media="screen" href="${roo_css_url}"></link>
这对我来说似乎完全没有必要。我们从 spring:theme 代码列表中调用一个变量。将其分配给视图范围中的变量，然后调用该视图变量
理想情况下，我希望有一些路径标记，例如： ${imagePage}、${stylePath} 等。我们可以插入并用于软链接。
希望有人能给我指出一些高质量的 SpringMVC 文档或给出一些示例。谢谢
更新：
我已经看到了一些示例，engfer 在下面发布了一个示例，建议在 html 中使用 spring 标签来输出 href，如下所示
<a href="<spring:url url='/about'/ />">About</a>
这是可以接受的，但是我从 jetty 收到以下错误
Caused by: org.apache.jasper.JasperException: /WEB-INF/views/footer.jspx(6,22) The value of attribute "href" associated with an element type "null" must not contain the '<' character.
我是否缺少编码的某些内容？还是DTD？
更新：
显然，内联 href 样式仅适用于 .jsp 文件，因为 .jspx （我使用的）是严格的 xml。 .jspx 相对于 .jsp 有哪些优点？
I am new to spring MVC coming with experience using PHP MVC frameworks and ROR. I am having a hard time finding the appropriate way to organize and include front end assets into the view templates.
Here is the default code Roo produces for the default style sheet:
<spring:theme code="styleSheet" var="roo_css"/>
<spring:url value="/${roo_css}" var="roo_css_url"/>
<spring:url value="/static/images/favicon.ico" var="favicon" />
<link rel="stylesheet" type="text/css" media="screen" href="${roo_css_url}"></link>
This seems totally unnecessary to me. We are calling a variable from the spring:theme code list. Assigning it to a variable in the view scope/ and then calling that view variable for the
Ideally I would like to have some path tokens like: ${imagePage}, ${stylePath}, etc. That we could drop in and use for soft linking.
Hopefully somebody can point me to some quality SpringMVC documentation or give some examples. Thanks
Update:
I have seen a few examples and engfer has posted one below that suggest using the spring tags within the html to ouput the href like so
<a href="<spring:url url='/about'/ />">About</a>
This would be acceptable however I am getting the following error from jetty
Caused by: org.apache.jasper.JasperException: /WEB-INF/views/footer.jspx(6,22) The value of attribute "href" associated with an element type "null" must not contain the '<' character.
Am I missing something with the encoding? or DTD?
Update:
So apparently the in-line href style only works with .jsp files as .jspx (What im using) is strict xml. What are the benefits of .jspx over .jsp and

您从 Roo 提供的代码有点不必要。如果您按照 tkeE2036 指出的那样查看 Spring MVC 文档...您将看到主题部分 http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-themeresolver
Spring 主题标签使您能够将 CSS/图像/js（想象一个包含单词“Hello”的图像，需要将其更改为英语/西班牙语/等）国际化为单独的国际化主题文件，如下所示http://java.sun.com/javase /6/docs/api/java/util/ResourceBundle.html 约定，Spring 将自动解析正确的资源捆绑主题。
如果您仍然想要
${imagePath}或其他内容，您可以使用The code you have provided from Roo is a little unnecessary. If you look at the Spring MVC documentation as tkeE2036 pointed out... you will see the themes section http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-themeresolver
The Spring theme tag gives you the ability to internationalize your CSS/images/js (imagine an image that has the word 'Hello' which needs to be changed for English/Spanish/etc) into separate internationalized theme files that follow the http://java.sun.com/javase/6/docs/api/java/util/ResourceBundle.html convention and Spring will automatically resolve the correct resource bundled theme.
If you still want your
${imagePath}or whatever, you can use the<spring:url/>tag to get your job done.
