java - 在 jBoss AS 中创建模块

Question

我正在使用 jBoss AS 7 来发布我的各种项目，并且所有项目都使用 Jersey API，因此我不想在每个项目中都部署它，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 并在该文件夹中放置了 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"/>
    </properties>
    <resources>
        <resource-root path="jersey-bundle-1.12.jar"/>
        <resource-root path="asm-3.1.jar"/>
        <resource-root path="jackson-core-asl-1.9.2.jar"/>
        <resource-root path="jackson-jaxrs-1.9.2.jar"/>
        <resource-root path="jackson-mapper-asl-1.9.2.jar"/>
        <resource-root path="jackson-xc-1.9.2.jar"/>        
        <resource-root path="jersey-client-1.12.jar"/>
        <resource-root path="jersey-core-1.12.jar"/>
        <resource-root path="jersey-json-1.12.jar"/>
        <resource-root path="jersey-server-1.12.jar"/>
        <resource-root path="jersey-servlet-1.12.jar"/>
        <resource-root path="jettison-1.1.jar"/>
        <resource-root path="jsr311-api-1.1.1.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <module name="org.jboss.staxmapper"/>
        <module name="org.jboss.as.controller"/>
        <module name="org.jboss.as.server"/>
        <module name="org.jboss.modules"/>
        <module name="org.jboss.msc"/>
        <module name="org.jboss.logging"/>
        <module name="org.jboss.vfs"/>
    </dependencies>
</module>

为了防止使用 jBoss JAX-RS，我从文件 JBOSS_HOME\standalone\standalone.xml 中删除了以下行:

<subsystem xmlns="urn:jboss:domain:jaxrs:1.0"/>
<extension module="org.jboss.as.jaxrs"/>

在 MyProjectEAR\META-INF 文件夹中，我创建了具有以下结构的 jboss-deployment-structure.xml 文件:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.0">
   <deployment>
      <dependencies>
        <module name="com.sun.jersey" slot="main" >
            <imports>
                <include path="META-INF/**"/>
                <include path="**"/>
            </imports>
        </module>
      </dependencies>
   </deployment>
</jboss-deployment-structure>

我的 MyProject\webContent\web.xml 文件是这样的:

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
    <display-name> MyProject </display-name>

    <servlet>
        <description>
        </description>
        <servlet-name>Jersey Servlet</servlet-name>
        <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
        <init-param>
            <description></description>
            <param-name>javax.ws.rs.Application</param-name>
            <param-value>com.MyProject.service.REST_Application</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>Jersey Servlet</servlet-name>
        <url-pattern>/jaxrs/*</url-pattern>
    </servlet-mapping>
</web-app>

MyProject\webContent\META-INF\MANIFEST.MF 中的 list 文件是这样的:

Manifest-Version: 1.0
Class-Path:

当我尝试部署项目时出现以下错误:

* 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您的模块的依赖。

Dependencies: com.sun.jersey
