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"]

我尝试：
localhost:8080/internship_projectType Status Report
Message The requested resource [/internship_project/] is not available
Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
我也尝试过：
localhost:8080/internship_project_war有什么想法可以解决这个问题吗？
尝试这样做
docker pull tomcat:latest
docker run -d --name mytomcat -p 8080:8080 tomcat:latest
docker exec -it mytomcat /bin/bash
mv webapps webapps2
mv webapps.dist/ webapps
exit
为了更好地理解：
下载tomcat： docker pull tomcat：最新
运行tomcat： docker run -d --name mytomcat -p 8080:8080 tomcat:最新
要更改为您在本示例中创建的容器，“mytomcat”是您的 tomcat 的名称： docker exec -it mytomcat /bin/bash
在文件夹之间移动文件进行备份： mv webapps webapps2
最后从“webapps.dist”复制“webapps”文件夹中缺少的文件： mv webapps.dist/webapps
退出
希望有帮助。
