tomcat - 在 tomcat 上部署的 war 文件给出 404 错误

Question

我已经使用 ant build.xml 文件成功地将我的小型 Web 应用程序的 war 文件部署到本地 tomcat 7.0.42 服务器。当我输入我的应用程序的 url localhost:8080/springapp/index.jsp 时，我收到 404 错误。我不明白为什么部署war文件时会出错。

我知道我的部署是成功的，因为我可以在 tomcat 管理器应用 localhost:8080/manager 中看到列出的 /springapp。我一直在关注本教程，http://docs.spring.io/docs/Spring-MVC-step-by-step/part1.html ，几乎完全除了改变一些东西，因为我正在使用 tomcat 7 并且它正在使用 tomcat 6。我目前正在执行步骤 1.4。任何帮助将不胜感激，我已经在这个问题上停留了一天多的谷歌搜索和故障排除。

这是我的 build.xml:

这是我的 web.xml 文件:

        <welcome-file-list>
            <welcome>
                index.jsp
            </welcome>
        </welcome-file-list>

</web-app>

这是我的 properties.build 文件:

appserver.home=/Users/joe/projects/tomcat
appserver.lib=${appserver.home}/lib

deploy.path=${appserver.home}/webapps

tomcat.manager.url=http://localhost:8080/manager/text
tomcat.manager.username=someone
tomcat.manager.password=something

这是我的 tomcat-users.xml 文件:

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
    <role rolename="manager-gui"/>
    <role rolename="manager-script"/>
    <role rolename="manager-jmx"/>
    <role rolename="manager-status"/>
    <user username="someone" password="something" 
          roles="manager-gui,manager-script,manager-jmx,manager-status"/>
</tomcat-users>

我解决了这个问题。我的 index.jsp 文件位于/webapps/springapp/WEB-INF/index.jsp，而它本应位于/webapps/springapp/index.jsp。愚蠢的错误。感谢 JB Nizet 的帮助。
