Grails 2 应用程序无法在 JBOSS : BeanCreationException 上部署

Question

在将我的一个应用程序从 Grails 1.3.7 升级到 2.1.0 并安装了几个额外的插件后，该应用程序将不再部署在用于生产的 JBOSS AS 5.1 上。
我从 JBOSS 服务器日志中得到的错误如下:

13:39:10,263 ERROR [[/]] Exception sending context initialized event to listener instance of class org.codehaus.groovy.grails.web.context.GrailsContextLoaderListener

为了解决我之前遇到的另一个问题(LifecycleException/ReflectionException:找不到方法 addChild...)，我在我的 WEB-INF 目录中引入了一个 jboss-classloading.xml。目前，这有以下内容:

<classloading xmlns="urn:jboss:classloading:1.0" name="ROOT.war" domain="DefaultDomain" top-level-classloader="true" export-all="NON_EMPTY" import-all="true" parent-first="false"> </classloading>

我怀疑当前的问题也与类加载有关，特别是因为我看到有问题的类是从 JBOSS lib 文件夹加载的，而不是从 war 的 lib 文件夹中的 jars 加载的:

 [Loaded org.hibernate.cfg.Mappings from jar:file:/usr/local/jboss-5.1.0.GA/common/lib/hibernate-core.jar!/]

显然，类 org.hibernate.cfg.Mappings 存在于 hibernate-core.jar 以及应用程序的 lib 文件夹(hibernate-core-3.6.10.Final.jar)中。因此，我试图以不同的方式调整 jboss-classloading.xml 文件，以强制 JBOSS 从 war 文件中加载这个特定的类，但无论我做什么，我都会收到相同的错误(或更早的不同错误)在部署周期中)。

有没有人知道如何解决这个问题？

Answer 1

有一个插件:)

http://grails.org/plugin/jbossas

文档位于此处:

http://grails-plugins.github.com/grails-jbossas/

这就是为什么会发生这种情况:

https://community.jboss.org/thread/156441

您需要配置 JBoss 以排除休眠 jar。 JBoss 安装中的 common/lib 中的 JBoss Hibernate jar 将首先加载，而不是 Grails Hibernate jar。这是一个类加载器顺序/偏好问题。

一个非常脏的解决方案是删除 common/lib 下的 jar，或者按照建议让类加载器工作以排除这些 jar。
