java - 为什么我不能在 Tomcat 上部署？无法在本地主机上发布 Tomcat v7.0 服务器的服务器配置。多个上下文的路径为 "/ROOT"？

Question

我必须在 Tomcat 7 上部署一个从我们内部 SVN 存储库检索到的 Java EE 应用程序(它是过去由其他人创建的)。

我已经使用 Maven 正确构建了它(Maven 构建过程似乎是成功的)。

问题是，当我尝试从 Eclipse 将其部署到 Tomcat 7 服务器时，我发现了一些困难(服务器配置良好，因为访问 URL localhost:8080 我获得了 Tomcat主页)。

我选择项目，然后右键单击并最终运行方式 --> 在服务器上运行。所以我选择了我的 Tomat 服务器。

部署不成功，因为我立即收到此错误消息弹出窗口:

点击Details按钮我得到了这条详细信息:

Could not publish server configuration for Tomcat v7.0 Server at localhost. Multiple Contexts have a path of "/ROOT".

究竟是什么意思？可能是什么问题呢？哪些附加信息对于故障排除很重要？

进入 Tomcat webapps 目录(我认为这是放置部署的 war 文件的目录，对吗？)，我发现:

C:\Users\Andrea\Documents\FAO\workspace\apache-tomcat-7.0.73\webapps\ROOT

似乎包含可通过 URL localhost:8080 访问的 Tomcat 网页。

那么这个应用程序可能是想使用相同的目录来部署我的应用程序吗？在我的项目中，我还发现了这个 run.sh bash 脚本:

cd ROOT
unzip -o ROOT.war
ln -s /data/gaezappdata/cache/images images/

所以似乎尝试以某种方式涉及ROOT目录。

您是否有一些想法可以帮助我更好地了解情况以及我如何尝试部署此应用程序？

编辑 1: 这是我的 server.xml Tomcat 配置文件，似乎有一个与我的 gaez-server 相关的“上下文”定义应用:

Answer 1

转到您的 tomcat 文件夹和/conf 和 server.xml，检查是否有多个“上下文”定义并删除重复项。
