java - Tomcat 上的 Spring RESTful Web 服务 404

标签 java spring maven tomcat

我正在尝试在 Tomcat 服务器实例上部署我的 Spring Framework 应用程序。关于这两个问题，我都是新手。

我的服务器是 Google Compute Engine 上的 x86_64 Debian 机器。我正在使用 Tomcat 8.0.36 和 Java 1.8。

我的问题类似于此线程中描述的问题: Spring RESTful Service as a WAR instead of JAR in Tomcat 我的意思是我收到 404“请求的资源不可用”。错误信息。相同的应用程序在我的本地环境中完美运行。

我可能完全按照上述线程中的步骤进行操作，但我的应用程序仍然无法运行。尽管我能够部署 WAR 文件并且我可以在 manager/html 中看到应用程序的状态为“正在运行”，但我无法通过 http 访问它或查看它的日志。

任何人都可以查看代码并帮助我理解原因吗？

最佳答案

@EnableWebMvc 未在配置中设置，它在 Controller 上设置。

在配置 (conf.xml) 中设置它。
