java - 服务 jboss.web.deployment.default-host./.realm 已经注册

Question

我正在尝试将三个不同的 ear 文件部署到同一个 Jboss 服务器...

其中一个没有上下文根，另外两个有，但不同。我的意思是，让我们把三只耳朵当作一只耳朵、两只耳朵和三只耳朵:

one.ear 有:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
    <context-root>/</context-root>
</jboss-web>

two.ear 有:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
    <context-root>/two</context-root>
</jboss-web>

three.ear 没有。

当我尝试为 Jboss (7 AS) 加注星标时，我得到了这个:

我读到当同一服务器中的两个应用程序具有相同的上下文根时可能会抛出此错误，但事实并非如此...发生了什么？

Answer 1

一般Jboss等容器的context root是

<context-root>/</context-root>

拦截所有传入的请求并传递给应用程序服务器。在你我怀疑冲突的应用程序是 JBoss AppServer root 本身，你可以使用以下 (enable-welcome-root="false")

<subsystem xmlns="urn:jboss:domain:web:1.0">
  <connector name="http" protocol="HTTP/1.1" socket-binding="http" scheme="http"/>
  <virtual-server name="localhost" enable-welcome-root="false">
    <alias name="example.com"/>
  </virtual-server>
</subsystem>
