【问题描述】：
我是 Spring 新手，我使用 sts/eclipse 开发了我的第一个 spring mvc web 应用程序。
对于部署到我的虚拟主机后出现的此错误，我需要您的帮助。
请注意，这个小应用程序在 eclipse 的 tomcat 服务器中运行良好。
spring 应用的上下文路径（应用上下文）是'realtyguide'。
Webhost 服务器是私有的 Tomcat 5.5。该应用程序被打包为一个 Maven 战争包。我将war文件（解压缩）部署在我的网络主机上作为虚拟主机（在server.xml中使用上下文路径=“/ realtyguide”）。
通过http://mysite.com/realtyguide/访问网站索引
索引页面正常，但是当访问索引页面引用的其他网页时，浏览器返回错误：
“在此服务器上找不到请求的 URL /realtyguide/page-name。”
我验证了索引页面检测到了我的应用程序上下文，因为我的链接使用了 c:url 和 spring:url 并且索引页面的页面源在我的链接中显示了上下文路径，例如 href="/realtyguide/resources/styles/standard.css” 和
<a href="/realtyguide/testpage" >Test - next page</a>
控制器似乎没有检测到映射的 URL。这可能是导致此错误的原因吗？

这里有一些控制器处理方法
@RequestMapping(value = "/", method=RequestMethod.GET)
public String setupForm(@ModelAttribute("searchFormBean") SearchFormBean searchFormBean, Model model) {
model.addAttribute("searchFormBean", searchFormBean);
return "index.tiledef"; // 'index' is a Tile definition in tiles.xml,
}
@RequestMapping(value = "/", method=RequestMethod.POST)
public String submitForm(@ModelAttribute("searchFormBean") SearchFormBean searchFormBean,
BindingResult result, SessionStatus status, Model model) {
searchFormValidator.validate(searchFormBean, result);
if (result.hasErrors()) {
model.addAttribute("searchFormBean", searchFormBean);
return "index.tiledef";
} else {
String searchTerm = searchFormBean.getSearchTerm();
searchTerm = searchTerm.replaceAll(" ","_");
return "redirect:/propertylistings/" + searchTerm + "/1"; // If no errors - display the listings page
}
}
@RequestMapping("/testpage")
public String gotoNextPage() {
return "nextpage.tiledef";
}
这是 webhosts tomcat/conf/server.xml

这个小应用程序在 eclipse/springsource 工具套件中运行良好。
找不到此 URL 错误的解决方案是什么？请帮帮我。
问题已解决
我怀疑我的虚拟主机服务器可能配置错误，但我无法检查，因为我有一个共享主机计划。为了验证问题不在于我的应用程序，我将应用程序部署在笔记本电脑中 eclipse 之外的本地 Tomcat 中。它运行完美。
所以我再次向技术支持报告“Tomcat servlet 未加载”。我坚持要技术支持，问题出在他们头上。他们的apache配置可能有问题。 Apache 与 Tomcat 的对话不正确。
他们终于修复了它，这是我从他们那里收到的确认信息 - “我们更改了服务器配置文件中的一些设置，以便对您的域的所有请求都将由 tomcat 而不是 Apache 处理。”
我希望这对使用共享主机计划并遇到相同错误的人有所帮助。如果您觉得您的 Tomcat 服务器设置正确，但仍然不断收到 URL 未找到错误，请坚持让您的技术支持人员查看他们的服务器配置。或者，如果您负担得起的话，可以购买一台专用服务器，这样您就可以完全控制您的 apache 服务器和 tomcat。
