何时以及为什么我需要一个Spring应用程序的jboss-deployment-structure.xml？ [英] When and why would I need a jboss-deployment-structure.xml for a Spring application?

问题描述

我试图了解如何在Spring应用程序中使用JBoss EAP6。我有一个示例OpenShift应用程序，它包含一个 jboss-deployment-structure.xml 文件。

I am trying to understand how to use JBoss EAP6 with Spring applications. I have a sample OpenShift application and it contains a jboss-deployment-structure.xml file.

我发现了一些有关此文件的文档，但我不清楚为什么以及何时应该将这些文件与Spring应用程序一起使用。内容如下：

I found some documentation about this file, but I am not clear why and when one should use those files with Spring applications. The content is the following:

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.0">
   <deployment>
       <dependencies>
            <module name="com.h2database.h2"/>
            <module name="org.codehaus.jackson.jackson-core-asl"/>
            <module name="org.codehaus.jackson.jackson-mapper-asl"/>
            <module name="org.slf4j"/>
       </dependencies>
   </deployment>
</jboss-deployment-structure>

为什么需要声明对模块的依赖？什么是JBoss范例中的模块？是否有可能没有这个xml文件？

Why does one need to declare dependencies to modules? And what are modules in the JBoss paradigm? Is it possible to live without this xml file?

推荐答案

只要你的应用程序没有任何类加载问题你就可以了不需要jboss-deployment-structure.xml文件。但是一旦遇到这种麻烦，jboss-deployment-structure.xml中的依赖管理就会成为你的朋友。

As long as you don't have any classloading problems with your application you don't need the jboss-deployment-structure.xml file. But once you have trouble of such kind the dependency management in jboss-deployment-structure.xml would be your friend.

本文解释了很好的模块是。

我想简而言之，你可以说所有部署为WAR，JAR或EAR是一个模块。这些模块称为动态模块。除了它们之外，$ JBOSS_HOME / modules中还有静态模块。唯一的区别是它们是如何打包的。

I think in short you can say that everything that is deployed as WAR, JAR or EAR is a module. These modules are referred to as dynamic modules. Beside them there are static modules in $JBOSS_HOME/modules. The only difference is how they are packaged.
