Question

我有一个Spring MVC应用程序，直到现在，当我在pom.xml中更改了某些内容时，它运行良好。当我启动服务器或应用程序时，我没有收到任何错误，但当我尝试从我的应用程序访问页面时，我得到：

HTTP Status 404 -
type Status report
message
description The requested resource is not available.

所以，这是我的pom.xml文件的一部分：

哪里可能是问题？

Answer 1

HTTP 404表示找不到资源。

网址映射不正确

（或）

未启动附加到该特定URL映射的服务。

1）首先检查DateConf处的映射。此页面上是否列出了URL端点？

2）您是否在Spring Boot（或）服务器启动时看到任何错误？

Answer 2

K139是对的，可能您没有点击正确部署的网址。做一个：

tail -f TOMCAT/logs/*

部署上的

根本没有显示任何奇怪的东西？您是如何配置日志记录设置的（使用slf4j进行tomcat和spring-boot）？

这是下次给你的建议（如果你现在没有这样做）：1）使用版本控制工具，2）经常提交。通过这种方式，您将了解破坏应用程序的更改。

Answer 3

我的猜测是问题来自您的服务器，完全从菜单中删除您的服务器：
窗口 - ＆gt;偏好 - ＆gt;服务器 - ＆gt;运行时环境
选择并删除您的服务器，然后再次添加您的Apache tomcat服务器 根本不改变或操纵您的服务器
现在再次运行你的项目希望在经过近一年的挑战后帮助我帮助我

Apache Tomcat和Spring MVC。 HTTP状态404
