Apache Servicemix 学习（3） ------ 创建service unit

ServiceMix提供了几个默认的mavne命令，可以方便的开发出servicemix工程。比如：用servicemix-service-unit来创建一个service unit工程。servicemix提供的几个内置命令列表：

servicemix-binding-component
servicemix-service-assembly 
servicemix-service-engine 
servicemix-service-unit 
servicemix-shared-library

在工程目录（/opt/ericWorkspace/servicemix ）下运行命令：

mvn archetype:create -DarchetypeArtifactId=servicemix-service-unit -DarchetypeGroupId=org.apache.servicemix.tooling -DartifactId=tutorial-file-su

如果出现如下信息：

eric@eric-laptop:/opt/ericWorkspace/servicemix$ 

则说明创建service unit成功。
在工程目录（servicemix）下会生成tutorial-file-su子模块。
tutorial-file-su子模块目录结构：

tutorial-file-su
                pom.xml
                src
                   main
                       resources

修改pom.xml文件，将name改为 Tutorial :: File SU

<project>
  ...
  <name>Tutorial :: File SU</name>
  ...
</project>

同时。增加一个依赖类包：

<dependency>
    <groupId>org.apache.servicemix</groupId>
    <artifactId>servicemix-file</artifactId>
    <version>${servicemix-version}</version>
  </dependency>

整个pom文件内容：

这只是一个非常简单的service unit工程，并没有java代码，只是利用了servicemix内置的service unit，如果能够让servicemix支持service unit，那么我就要写xbean.xml配置文件，将其配置到servicemix中。

在tutorial-file-su/src/main/resources目录下新建xbean.xml文件，内容为：

<beans xmlns:file="http://servicemix.apache.org/file/1.0"
	xmlns:tut="urn:servicemix2:tutorial2">
	
	<file:sender service="tut:file" 
             endpoint="sender"
             directory="file:/home/eric/temp/sender" />

	<file:poller service="tut:file" 
             endpoint="poller"
             file="file:/home/eric/temp/poller" 
             targetService="tut:file"
             targetEndpoint="tut:wiretap"/>
</beans>

此外，我们还要创建 service assembly工程，
输入命令：

mvn archetype:create -DarchetypeArtifactId=servicemix-service-assembly -DarchetypeGroupId=org.apache.servicemix.tooling -DartifactId=tutorial-sa

当出现如下信息时

[INFO] ------------------------------------------------------------------------
[INFO] Building Tutorial
[INFO]    task-segment: [archetype:create] (aggregator-style)
[INFO] ------------------------------------------------------------------------
[INFO] [archetype:create {execution: default-cli}]

此时，sa工程创建成功，
sa子模块目录结构为：

tutorial-sa
           pom.xml

修改pom,xml

  <properties>
    <servicemix-version>3.2.3</servicemix-version>
  </properties>
</project>

此时，一个完整的工程创建完成。
在工程目录（servicemix）下运行命令：

mvn install

当编译运行成功后，在目录下 servicemix/tutorial-sa/target 会生成此工程的jar包：tutorial-sa-1.0-SNAPSHOT.jar。

部署：
只要将tutorial-sa-1.0-SNAPSHOT.jar拷贝到 %SERVICEMIX/hotdeploy目录下即可。
