我正在从书中弹簧食谱中制作一个示例，并且我似乎无法将示例部署到 tomcat 中。我正在尝试打开 messageList.htm 页面，但我总是收到 HTTP 状态 404 错误。

有人可以帮助我吗？

提前谢谢

这是代码：

HTTP 404 意味着您在浏览器中提供的 URL 没有映射到您希望的页面。

如果您将应用程序作为名为 foo.war 的 WAR 文件部署到 Tomcat，我希望 URL 如下所示：

http://localhost:8080/foo/messageList.html

使用该语法，直到正确为止。

如果 Maven 对您来说是一个黑匣子，我建议您手动创建和部署一个 WAR 文件，直到您弄明白为止。
