Spring App 未使用 Tomcat 服务器从 Intellij 运行

【问题标题】：Spring App is not running from Intellij with Tomcat ServerSpring App 未使用 Tomcat 服务器从 Intellij 运行
【发布时间】：2021-10-24 16:01:36
【问题描述】：

如果我使用 Tomcat 服务器从 Intellij 运行我的 spring 应用程序，它会给我：

HTTP Status 404 – Not Found
Type Status Report

Message The requested resource [/] is not available

Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

Apache Tomcat/9.0.52

但如果我将我的app.war 放入tomcat/webapps/ 作为ROOT.war，它就可以完美地工作。

我只有在尝试从Intellij运行时才会遇到问题

这是配置：

这是部署：

这是输出：

我想从根目录运行我的应用程序：localhost:8080/。

为什么我会收到来自 Tomcat 的404 - Not Found？以及如何解决？

如果您需要更多详细信息，请告诉我。

Intellij IDEA 版本：2021.2 Ultimate Edition

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <version>2.5.3</version>
</dependency>

P.S.：我认为有些地方没有正确部署。因为部署后，在控制台中不会出现那么大的SPRING 徽标和有关初始化的日志。或者这不一定？

【问题讨论】：

  • 您可以连接到 Tomcat 管理器 (http://localhost:8080/manager) 以查看 Intellij 将您的应用程序部署在哪里。
  • @PiotrP.Karwasz ，我检查了manager，我可以在列表中看到我的应用程序/ 和/manager，我不知道如何在磁盘上找到位置。
  • @PiotrP.Karwasz ，我认为有些东西没有正确部署。如果我没记错的话，部署后，控制台中应该会出现一些SPRING 徽标和更多细节。但现在不见了。
  • 检查其他日志（catalina.&lt;date&gt;.log 和 localhost.&lt;date&gt;.log）。
  • @PiotrP.Karwasz ，我解决了这个问题。在Run/Debug Configuration Before Launch 我删除了所有内容。现在工作。谢谢你的帮助。

【解决方案1】：

我找到了解决问题的方法。

我的问题已通过删除 Run/Debug Configuration -&gt; Before Launch 中的所有内容得到解决

我还添加了maven clean install 命令，而不是那里的内容。
