我正在尝试将我的 JBOSS 5.1 应用程序迁移到 JBOSS 7.0.2。在管理控制台中，我选择部署 -> 添加内容和我的 .war 并尝试启用它。我已经解决了一些问题，但无法弄清楚这个：（总之，最后是长）

JBoss AS 7 does class-loading in a diff way.
JBoss AS 7 以不同的方式加载类。
All classes in the WAR are loaded with the same class loader. This means classes packaged in the WEB-INF/lib are treated the same as classes in WEB-INF/classes. Hence it works for you.
WAR 中的所有类都使用相同的类加载器加载。这意味着打包在 WEB-INF/lib 中的类被视为与 WEB-INF/classes 中的类相同。因此它对你有用。
But as you have said correctly your WEB-INF/lib is bloated.This would not be the correct way.
但是正如您所说的那样，您的 WEB-INF/lib 是臃肿的。这不是正确的方法。
You would need to make a module : Goto modules folder, make folder structure with main folder and put your jar and modules.xml with entries in it. Something like :
您需要创建一个模块：转到模块文件夹，使用主文件夹创建文件夹结构，并将带有条目的 jar 和 modules.xml 放入其中。就像是 ：
<main-class name="org.jboss.msc.Version"/>
<resources>
<resource-root path="jboss-msc-1.0.1.GA.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="org.jboss.logging"/>
<module name="org.jboss.modules"/>
<!-- Optional deps -->
<module name="javax.inject.api" optional="true"/>
<module name="org.jboss.threads" optional="true"/>
<module name="org.jboss.vfs" optional="true"/>
</dependencies>
You would also need to update MANIFEST as well. Details are here : https://docs.jboss.org/author/display/MODULES/Module+descriptors
您还需要更新 MANIFEST。详细信息在这里：https: //docs.jboss.org/author/display/MODULES/Module+descriptors

I would not put those JARs in that directory. Try them in your WAR file's WEB-INF/lib. The class loader will find them there.
我不会将那些 JAR 放在那个目录中。在您的 WAR 文件的 WEB-INF/lib 中尝试它们。类加载器会在那里找到它们。
You need to understand that all Java EE app servers use a hierarchy of class loaders: bootstrap, server, application. JBoss wasn't finding that class when it needed to.
您需要了解所有 Java EE 应用服务器都使用类加载器的层次结构：引导程序、服务器、应用程序。JBoss 在需要的时候没有找到那个类。

There is a major change Jboss 7 when compared to previous versions.If you want to access any libraries outside your war file, it should be installed as module. Check https://docs.jboss.org/author/display/MODULES/IntroductionIn this case you should install Spring as module and specify the name of the module as dependency in your application's manifest file(check Manifest module information)
与以前的版本相比，Jboss 7 有一个重大变化。如果你想访问你的 war 文件之外的任何库，它应该作为模块安装。检查https://docs.jboss.org/author/display/MODULES/Introduction在这种情况下，您应该将 Spring 作为模块安装，并在应用程序的清单文件中指定模块的名称作为依赖项（检查清单模块信息）
