java - Tomcat服务器404

Question

我有一个使用 Maven3 的项目在 Tomcat 7 上运行。

Tomcat正在运行，maven项目成功部署到tomcat；但是，当我访问我的项目链接 http://localhost:8080/myWebApp 时，我收到 404 错误。

我想知道是否必须先登录 tomcat？

我对这个设置还很陌生，所以如果我遗漏了一些明显的东西，请原谅我的无知。

我按照说明修复了第一次编辑中的 Spring 错误 here但我仍然收到 404 错误。任何 tomcat 日志上都没有错误。

我的pom.xml tomcat插件是

    <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>tomcat-maven-plugin</artifactId>
         <configuration>
               <url>http://localhost:8080/manager/text</url>
               <server>tomcat</server>
              <path>/myWebApp</path>
         </configuration>
    </plugin>

很可能它是部署在另一个上下文名称下的。考虑到您使用的是 Maven，可能包含版本号，因此您可以通过 http://localhost:8080/myWebApp-0.0.1-SNAPSHOT 或类似的内容进行访问，具体取决于您项目的实际版本。

我认为 Tomcat 日志指示了上下文名称。
