apache camel

这些天，我在玩Wildfly ， Apache Camel和Spring 。

在EAR / WAR之间进行通信的一种简单方法是使用Camel的direct-vm组件。 有或没有骆驼，有很多方法可以实现这一目标。 骆驼在WildFly中就像一个饰物，不需要任何额外的配置。 骆驼很棒！！！

为了避免将Spring和Camel所需的所有JAR打包到我的应用程序中，我使用出色的JBoss Modules框架（WildFly已经使用过）创建了两个模块。 然后，我可以引用这两个框架，而无需在应用程序（EAR / WAR）中打包所有这些JAR。

创建Spring模块

• 转到WildFly主页目录： $> cd /home/torun/jboss/wildfly/wildfly-8.0.0.Beta1
• 创建Spring模块目录结构：
  • $> mkdir -p modules / org / springframework / 3.2.5.RELEASE
• 在这个新目录中，创建具有以下内容的module.xml文件：

<module xmlns="urn:jboss:module:1.3" name="org.springframework" slot="3.2.5.RELEASE"><resources><resource-root path="aopalliance-1.0.jar"/><resource-root path="aspectjrt-1.7.4.jar"/><resource-root path="aspectjtools-1.7.4.jar"/><resource-root path="aspectjweaver-1.7.4.jar"/><resource-root path="org.aspectj.matcher-1.7.4.jar"/><resource-root path="spring-aop-3.2.5.RELEASE.jar"/><resource-root path="spring-aspects-3.2.5.RELEASE.jar"/><resource-root path="spring-beans-3.2.5.RELEASE.jar"/><resource-root path="spring-context-3.2.5.RELEASE.jar"/><resource-root path="spring-context-support-3.2.5.RELEASE.jar"/><resource-root path="spring-core-3.2.5.RELEASE.jar"/><resource-root path="spring-expression-3.2.5.RELEASE.jar"/><resource-root path="spring-jdbc-3.2.5.RELEASE.jar"/><resource-root path="spring-orm-3.2.5.RELEASE.jar"/><resource-root path="spring-oxm-3.2.5.RELEASE.jar"/><resource-root path="spring-tx-3.2.5.RELEASE.jar"/><resource-root path="spring-web-3.2.5.RELEASE.jar"/><resource-root path="spring-webmvc-3.2.5.RELEASE.jar"/><resource-root path="spring-webmvc-portlet-3.2.5.RELEASE.jar"/></resources><dependencies><module name="javaee.api"/><module name="org.apache.commons.logging"/><module name="org.jboss.vfs"/><module name="org.hibernate"/><module name="javax.el.api" export="true"/><module name="com.sun.xml.bind" export="true"/></dependencies>
</module>

• 然后在此新目录内添加所有提到为“ resource-root”的JAR。
• 您已经完成了Spring模块！！！
• 现在，您可以在EAR / WAR中使用“ jboss-deployment-structure.xml”中的下一行来引用spring模块：
  • <module name =” org.springframework” slot =“ 3.2.5.RELEASE” />

创建骆驼模块

• 创建骆驼模块目录结构：
  • $> mkdir -p modules / org / apache / camel / 2.12.1
• 在这个新目录中，创建具有以下内容的module.xml文件：

<module xmlns="urn:jboss:module:1.3" name="org.apache.camel" slot="2.12.1"><resources><resource-root path="camel-core-2.12.1.jar"/><resource-root path="camel-spring-2.12.1.jar"/><resource-root path="jaxb-impl-2.2.6.jar"/></resources><dependencies><module name="org.springframework" slot="3.2.5.RELEASE" /><module name="org.slf4j"/><module name="javax.xml.bind.api"/><module name="javax.api"/><module name="sun.jdk" /></dependencies>
</module>

• 然后在此新目录内添加所有提到为“ resource-root”的JAR。
• 您已经与骆驼模块一起完成了！！！
• 现在，您可以在EAR / WAR中使用“ jboss-deployment-structure.xml”中的下一行来引用骆驼模块：
  • <module name =“” org.apache.camel” slot =” 2.12.1” />

您可以从Spring或Camel模块中删除一些jar依赖项，但是这些只是我当前的设置，我知道它可以工作！

还有一个重要的注意事项。 在尝试为这些模块找到正确的JAR时，我遇到了一些例外情况……因此，如果您忘记了任何JAR，则可能会看到以下任何例外情况：
