问题描述
所以我花了将近一天的时间试图让tomcat接受我的.war，所以也许你们可以帮助我。
我做了什么：
- 将.war文件复制到/ webapps目录
- 使用“ sudo systemctl stop tomcat8”停止了tomcat
- 使用“ sudo systemctl start tomcat8”启动tomcat
此后，我检查了我的应用程序是否在那里并且仍然得到默认的“ It Works！”。的tomcat页面。所以我检查了catalina.out，并有以下几行：

所以我认为问题是在 demo-0.0.1-SNAPSHOT.war 应用之后部署了标准 ROOT 应用。因此，我删除了 ROOT 文件夹并重新启动了服务器，但是仍然无法访问我的服务。现在，我得到一个404错误页面。 catalina.out：

因此，它实际上是在部署我的war文件-但无论如何都不完全。 我尝试通过 {ip}：80 / 和 {ip}：80 / demo-0.0.1-SNAPSHOT /
致电服务其他信息：
- tomcat位于树莓派上，距离我大约100公里
- 树莓派还为那里的网络托管了一个pi孔
- catalina.out日志在两个启动中的每个启动处都有其他行（带有警告）。我将从最后一次启动时发布完整的日志
希望我能提供足够的信息！ 预先谢谢你
