在jBoss AS中创建模块

Gon*_*oso 9 java deployment configuration jersey jboss7.x

我正在使用jBoss AS 7发布我的各种项目,并且所有项目都使用Jersey API,因此我不想在每个项目中部署它,而是想为它创建一个模块.为此,我创建了文件夹JBOSS_HOME\modules\com\sun\Jersey\main,在这个文件夹中我放置了Jersey jar和文件module.xml:

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="com.sun.jersey">
    <properties>
        <property name="jboss.api" value="private"/>

*编辑:*如果我将Jersey API放在JBOSS_HOME\modules\com\sun\jsf-impl\main中并更改相应的module.xml,一切正常.这个位置有什么不同？

您需要在部署中指定对模块的依赖关系.

META-INF\MANIFEST.MF

Dependencies: com.sun.jersey

我需要补充一下

<subsystem xmlns="urn:jboss:domain:ee:1.0">
    <global-modules>
        <module name="com.sun.jersey" slot="main"/>
    </global-modules>
</subsystem>

进入JBOSS_HOME\standalone\configuration\standalone.xml配置文件

已经有一个答案，但是我想为以后的读者澄清一下这个话题。

在三个位置中，将JBoss模块声明为JBoss 7（EAP 6）中其他部署的依赖项：

  1. 全局模块
  2. 清单文件
  3. jboss-deployment-structure.xml

在大多数情况下，它们是替代方法。

1.全局模块

全局模块是JBoss Enterprise Application Platform 6作为对每个应用程序的依赖关系而提供的模块。通过将任何模块添加到应用程序服务器的全局模块列表中，可以使其成为全局模块。

您可以从管理控制台（请参阅源代码）或通过编辑standalone.xml轻松添加全局模块：

<subsystem xmlns="urn:jboss:domain:ee:1.0" >            
  <global-modules>
    <!-- Add global modules here -->
    <module name="org.javassist" slot="main" />            
  </global-modules> 
</subsystem>

2. MANIFEST.MF

将一个Dependencies条目添加到MANIFEST.MF文件中，并使用逗号分隔的依赖关系模块名称列表。

Dependencies: org.javassist, org.apache.velocity

如果您使用的是Maven，则只需配置一些插件。例如耳朵。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-ear-plugin</artifactId>
    <configuration>
        <version>6</version>
        ...
        <defaultLibBundleDir>lib</defaultLibBundleDir>
        <archive>
            <manifestEntries>
                <Dependencies>
                    com.foo.bar.test-module export optional
                    <!-- Beware of new lines! They can quietly break the conf -->
                </Dependencies>
            </manifestEntries>
        </archive>
        <modules>
            ...
        </modules>
    </configuration>
</plugin>
Run Code Online (Sandbox Code Playgroud)

注意：使用export可使com.foo.bar.test-module耳朵中所有捆绑的模块可见。

3. jboss-deployment-structure.xml

jboss-deployment-structure.xml是JBoss特定的部署描述符，可用于以细粒度方式控制类加载。应将其放置在META-INF（或用于Web部署的WEB-INF）的顶级部署中

您可以从下面的文档中看到与MANIFEST.MF相比，它有多强大。对于最简单的情况，这是一个示例：

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <ear-subdeployments-isolated>false</ear-subdeployments-isolated>
    <deployment>
        <dependencies>
            <!-- Add modules here -->
            <module name="com.foo.bar.test-module" export="true"/>
            <module name="org.apache.axis.axis-jaxrpc" export="true"/>
        </dependencies>
    </deployment>
</jboss-deployment-structure>
Run Code Online (Sandbox Code Playgroud)

注意1：就像MANIFEST.MF一样，设置export=true使com.foo.bar.test-module在耳朵中捆绑的所有模块可见。

注2：该属性optional=true/false在jboss-deployment-structure.xml中也可用，但不适用于特定版本（可能<EAP 6.4.7）。如果需要，请签出。

希望能帮助到你。
