【问题描述】:
我对 Spring 框架和 Web 应用程序很陌生,尽管我对 Java 有一定的经验。当我在本地 tomcat 服务器上运行我的网站时,URL 是:http://localhost:8080/myApp/
现在请求映射将我委托到我的主页:
@RequestMapping(value = "/", method = RequestMethod.GET)
public String someMethod(Model model) { ...
return "index"; }
现在在文件index.xhtml 中,我使用<a href="apps/">link</a> 链接到另一个页面
但是当我想链接回索引页面时,我必须使用<a href="../index/">link</a>。我搜索了一个解决方案,发现:
<spring:url value='/apps' var="apps_url" />
<a href="${apps_url}">link</a>
但 spring:url 总是解析为 http://localhost:8080/myApp/ - 我当前所在的页面。此外,当我只使用这样的链接:<a href="/otherSite">link</a> 时,它总是解析为 http://localhost:8080/otherSite 而不是 http://localhost:8080/myApp/otherSite,就像我预期的那样。我怎样才能让我的链接工作? http://localhost:8080/myApp 是隐式定义为我的上下文还是可以/应该将其更改为 http://localhost:8080/?
另外,本地 tomcat 服务器上的 URL 和 Web 应用程序发布时的 URL 之间是否有任何联系?
这是我的一些应用程序文件:
