在openshift中运行项目后空白页面打开

问题描述：

我在openshift中部署了一个Web应用程序。尽管构建和部署是成功的，我上单击应用程序得到一个空白页：在openshift中运行项目后空白页面打开

该应用程序在本地系统中运行良好。请建议我如何解决这个问题。

删除配置文件标记并更正上下文根，工件标识为您的上下文根名称已解决该问题。

在构建日志看的.war文件的名称：

[INFO]建筑战争：/tmp/src/target/yourcontextrootname-0.0.1-SNAPSHOT.war

“yourcontextrootname “是应用程序的上下文根 - 您应该看到您的上下文根名称。（How to change context root of a dynamic web project in Eclipse?）

为了能够访问我的OpenShift3启动应用程序，我有过这样

...网址后，我的.war文件的名称追加adoreindia-adoreindia.a3c1.starter美-west-1.openshiftapps.com/yourcontextrootname-0.0.1-SNAPSHOT

生成日志显示战争文件的名称 - [INFO]建筑战争：/tmp/src/webapps/ROOT.war 我已经修改了Web应用程序根目录的上下文根。这不起作用，仍然显示空白页面。我在事件中发现了两条警告 - 1.无法为pod“adoreindia-3-deploy_adore-india（3805e0d4-99cf-11e7-a546-06579ed29230）”装入卷：超时等待卷挂接/挂载pod“adore-india”/“adoreindia-3-deploy”。未连接/未挂载的卷列表= [部署者令牌-ngq25] 2.同步错误pod – Arnab

我无法对这些警告说些什么。从来没有像这样的。这就是我的web应用程序的工作原理：构建由每次推送时git存储库中的webhook触发。在我的pom.xml中，我没有部分。可能有区别，这就是为什么你的.war文件被命名为ROOT。我认为上下文根本应该是以前的样子，我提供的链接仅用于澄清，其中可以找到上下文根的名称。除了这些信息我只能说，我必须在OpenShift3中重新创建Web应用程序多次，从头开始，才能正常运行。 – nikoalset
