【问题描述】：
我需要在 docker 容器中的 Tomcat 上收集简单的 spring 应用程序，但是当我尝试 localhost:8080 时，我得到：
404 Type Status Report
Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
Dockerfile：
FROM tomcat:latest
COPY target/internship_project.war /usr/local/tomcat/webapps/
EXPOSE 8080
CMD [\"catalina.sh\", \"run\"]
- docker build -t 应用程序。
- docker run --rm -it -p 8080:8080 应用程序

localhost:8080/internship_project_war并得到了同样的结果。任何想法如何解决这个问题？
-
这回答了你的问题了吗？ .war on tomcat on docker, 404 on servlet
-
不，我从这篇文章中做了所有事情，但是没有..
-
在您的情况下，您只需将
tomcat:latest替换为tomcat:9。 -
@PiotrP.Karwasz 是的，你是对的。但是现在，我有一个错误：
500 org.postgresql.util.PSQLException: Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.你知道为什么吗？我读到这是因为我在 docker 容器中有一个数据库，我必须使用 0.0.0.0 而不是 localhost，但这不起作用。
