所以我知道有几十个类似的帖子，但不幸的是没有一个对我有帮助。我只是想启动并运行一个演示 Spring MVC 项目。我正在尝试运行 Heroku 提供的模板项目（https://devcenter.heroku.com/articles/getting-started-with-heroku-eclipse）。我尝试了许多设置组合都无济于事。以下是默认设置：

人控制器.java：
@Controller
public class PersonController {
@Autowired
private PersonService personService;
@RequestMapping("/")
public String listPeople(Map<String, Object> map) {
map.put("person", new Person());
map.put("peopleList", personService.listPeople());
return "people";
}
@RequestMapping(value = "/add", method = RequestMethod.POST)
public String addPerson(@ModelAttribute("person") Person person, BindingResult result) {
personService.addPerson(person);
return "redirect:/people/";
}
@RequestMapping("/delete/{personId}")
public String deletePerson(@PathVariable("personId") Integer personId) {
personService.removePerson(personId);
return "redirect:/people/";
}
}
我在 webapp/WEB-INF/jsp/people/jsp 有一个“people.jsp”文件
我的 Tomcat 服务器的 server.xml 上下文元素如下所示：
<Context docBase="facultypublicationsdb" path="/facultypublicationsdb" reloadable="true" source="org.eclipse.jst.jee.server:facultypublicationsdb"/></Host>
每次我在 ( http://localhost:8080/facultypublicationsdb/) 的 Tomcat 上运行它时，我都会得到以下信息：
HTTP Status 404 - /facultypublicationsdb/
type Status report
message /facultypublicationsdb/
description The requested resource (/facultypublicationsdb/) is not available.
Apache Tomcat/7.0.21
我通过 Eclipse 在 Ubuntu 上运行它。我注意到没有 .war 被复制到/usr/share/tomcat7/webapps目录中。这应该发生吗？
有任何想法吗？
