Spring Boot Deployed in Tomcat gives 404 but works Stand-alone
提问by xelamitchell
I have been testing Spring Boot with embedded Tomcat for about a month now to build a REST API. Everything was working fine. We now want to deploy the API in a separate development environment which has a couple of other (non-Spring) applications running on a Tomcat container.
我已经使用嵌入式 Tomcat 测试 Spring Boot 大约一个月来构建 REST API。一切正常。我们现在想要在单独的开发环境中部署 API，该环境有几个其他（非 Spring）应用程序在 Tomcat 容器上运行。
I made the changes specified in Converting a Spring Boot JAR Application to a WAR using Mavenand Spring Boot Docs.
我进行了使用 Maven和Spring Boot Docs将 Spring Boot JAR 应用程序转换为 WAR 中指定的更改。
The deployment goes well (logs are fine, no errors) and looking at Tomcat management i see my application deployed. However, when I attempt to access http://localhost:8080/sophia/usersin curl I get 404.
部署进展顺利（日志正常，没有错误）并且查看 Tomcat 管理我看到我的应用程序已部署。但是，当我尝试在 curl 中访问http://localhost:8080/sophia/users 时，我得到 404。
Any help is much appreciated.
任何帮助深表感谢。

我试过访问

The first returns a 404 but with the CORS information from my CORS filter bean. The second return 404 without CORS information (which indicates the application has started and is configured but I do not seem to have access to the Controllers).
第一个返回 404 但带有来自我的 CORS 过滤器 bean 的 CORS 信息。第二个返回 404 没有 CORS 信息（这表明应用程序已启动并已配置，但我似乎无法访问控制器）。

When running an application the path to call consists of a couple of parts.
运行应用程序时，调用路径由几个部分组成。
The first is the base URL on which the application is deployed, in your case that is /sophia.
第一个是部署应用程序的基本 URL，在您的情况下是/sophia.
The second is the servlet mapping of the DispatcherServletin your case that is /sohpia/*.
第二个是DispatcherServlet在您的情况下的 servlet 映射，即/sohpia/*.
The third is the mapping of the controller inside the DispatcherServlet, in your example that is /users.
第三个是控制器内部的映射DispatcherServlet，在你的例子中就是/users.
All those things combined create the URL /sophia/sophia/users.
所有这些东西结合起来创建 URL /sophia/sophia/users。
The difference between the deployment as a WAR is that you included a separate URL to deploy on, when running as a jar it, by default, is deployed to /(the root).
作为 WAR 部署之间的区别在于，您包含了一个单独的 URL 来部署，当作为 jar 运行时，默认情况下，它被部署到/（根）。
You could fix it by putting /sophiaas the server.context-pathin the application.propertiesand map the DispatcherServletto /*or /. That will in both situations give you the URL you want (and expected).
您可以通过将/sophiaas放入 并将server.context-path其application.properties映射DispatcherServlet到/*或来修复它/。这将在两种情况下为您提供所需（和预期）的 URL。

check java -version means the if you complied war in java 8 and tomcat is running on java 7 then it doesn't work.
检查 java -version 意味着如果您在 java 8 中编译了 war 并且 tomcat 在 java 7 上运行，则它不起作用。

Have you tried extending the SpringBootServletInitializer and overriding the configure method? As stated here
您是否尝试过扩展 SpringBootServletInitializer 并覆盖 configure 方法？如前所述这里
The entry point for jar file is different [Main Class] when compared to running your app as war file inside a container.
jar 文件的入口点与在容器内作为 war 文件运行应用程序相比是不同的 [Main Class]。
Hope this helps.
希望这可以帮助。
