Tomcat:每个应用程序的请求的状态代码404

Question

我的Tomcat status code 404上部署的每个应用程序都会在我发出的每个请求中返回 我尝试过几个项目,helloworlds或者骷髅,每个项目的行为与其他项目相同:

---

我用过的一些项目:

https://github.com/mwarman/skeleton-ws-spring-boot

https://spring.io/guides/gs/rest-service/(我可以运行它,mvn spring-boot:run但它不能部署到Tomcat)

https://github.com/shagstrom/spring-mvc-hibernate-skeleton

---

我正在使用最新的Tomcat8 (8.0.27),Oracle JDK 8.我也试过Tomcat7了OpenJDK 7.使用的Tomcats在MAC和Debian上运行.我通过mvn和Intellij Idea构建应用程序.

Tomcats很干净,没有更改配置(除了添加manager-gui用户).

由于我尝试了很多不同的项目,我不相信代码中存在问题.它是在Tomcat的配置中吗？我怎样才能让它发挥作用？

如果您成功安装了 tomcat，您可能已经从浏览器http://localhost:8080/ URL看到了 tomcat 主页。（否则，需要先检查tomcat安装。）

我想您可能已经通过您提到的上述网站构建了 jar。我想知道您是否将该 jar 应用于您的 tomcat 中，因为您提到了任何其他项目的相同结果。为了应用java程序，你需要将jar或war应用到你的tomcat中。
