osgi1——camel与cxf发布webservice

经过三个月的osgi学习，今天打算总结一下osgi与blueprint结合，并且使用camel、cxf等框架去做ESB.

camel是apache下面一个非常著名的框架，定义了一套路由规则，他的根本原理就是，一端进来——处理——另外一端出去，基于这个高度抽象模型，他扩展的范围非常广，可以去整合HTTP,?ActiveMQJBI?or?CXF

首先先了解下camel与cxf发布webservice

webservice经常用于ESB,如果不用框架自己去实现的话会非常麻烦，所以我们要站在巨人的肩膀上去实现。请看下面blueprint.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
           xmlns:camel-cxf="http://camel.apache.org/schema/blueprint/cxf"
           xmlns:cxfcore="http://cxf.apache.org/blueprint/core"
           xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd

http://camel.apache.org/schema/blueprint/cxf http://camel.apache.org/schema/blueprint/cxf/camel-cxf.xsd
http://cxf.apache.org/blueprint/core http://cxf.apache.org/schemas/blueprint/core.xsd"
>

	<!--Web service-->
    <camel-cxf:cxfEndpoint id="myService"
                           address="http://0.0.0.0:8018/myosgi/camelwebservice"
                           serviceClass="com.cn.yyc.osgi.imywebservice"
                           bindingId="http://www.w3.org/2003/05/soap/bindings/HTTP/">
        <camel-cxf:properties>
            <entry key="dataFormat" value="POJO"/>
        </camel-cxf:properties>
    </camel-cxf:cxfEndpoint>
    
   <bean id="test1" class="com.cn.yyc.Test1"/>
    <camelContext  id="myCamelContext" xmlns="http://camel.apache.org/schema/blueprint" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                   xsi:schemaLocation="http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-blueprint.xsd">
        <route >
            <from uri="myService" />
            <log message="Request:${in.header.operationName}"/>
            <choice>
                <when>
                    <simple>${in.header.operationName} == 'test1'</simple>
                    <to uri="bean:test1"/>
                </when>
                <otherwise>
			<to uri="bean:test"/>
		</otherwise>
	    </choice>
	</route>
     </camelContext>
</blueprint>

上面配置中serviceClass的配置是一个接口，接口方法中可以定义接受的webservice参数和返回的参数，下面路由节点to到一个资源的时候，可以到很多地方，如果到bean的话，那么类就需要继承org.apache.camel.Processor，实现process方法

import org.apache.camel.Exchange;
import org.apache.camel.Processor;

/**
 *
 * @author Administrator
 */
public class Test1 implements Processor{

    @Override
    public void process(Exchange exchange) throws Exception {
        Response response=new Response();
        exchange.getOut().setBody(response);
    }
    
}

因此pom.xml，文件需要引入依赖

?<dependency>
? ? ? ? ? ? <groupId>org.apache.camel</groupId>
? ? ? ? ? ? <artifactId>camel-core</artifactId>
? ? ? ? ? ? <version>2.15.1</version>
</dependency>

?<dependency>
? ? ? ? ? ? <groupId>org.apache.cxf</groupId>
? ? ? ? ? ? <artifactId>cxf-core</artifactId>
? ? ? ? ? ? <version>3.0.4</version>
? ? ? ? ? ? <type>jar</type>
</dependency>

maven打包成bundle的时候，需要配置如下

<build>
        <plugins>
            <plugin>

可以将打包好的jar包放入servicemix运行，即可拿soapui软件测试
