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, ActiveMQ, JMS, JBI, SCA, MINA or CXF, WD等等。并且实现也非常简单，他可以用spring或者blueprint去简单配置即可使用。

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://aries.apache.org/xmlns/jpa/v1.1.0 http://aries.apache.org/schemas/jpa/jpa_110.xsd http://aries.apache.org/xmlns/transactions/v1.0.0 http://aries.apache.org/schemas/transaction/transactionv10.xsdhttp://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0 http://aries.apache.org/schemas/blueprint-cm/blueprint-cm-1.1.0.xsd http://camel.apache.org/schema/blueprint/cxf http://camel.apache.org/schema/blueprint/cxf/camel-cxf.xsdhttp://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>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-compiler-plugin</artifactId>                <version>2.3.2</version>                <configuration>                    <source>1.7</source>                    <target>1.7</target>                    <encoding>${project.build.sourceEncoding}</encoding>                </configuration>            </plugin>            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-source-plugin</artifactId>                <version>2.4</version>                <executions>                    <execution>                        <phase>deploy</phase>                        <goals>                            <goal>jar</goal>                        </goals>                    </execution>                </executions>            </plugin>            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-deploy-plugin</artifactId>                <version>2.8.2</version>                <configuration>                    <skip>false</skip>                </configuration>            </plugin>            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-javadoc-plugin</artifactId>                <version>2.10.3</version>                <configuration>                    <aggregate>true</aggregate>                </configuration>            </plugin>            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-surefire-plugin</artifactId>                <version>2.7.2</version>                <configuration>                    <skip>false</skip>                </configuration>            </plugin>            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-jar-plugin</artifactId>                <version>2.3.1</version>                <configuration>                    <archive>                        <manifest>                            <addClasspath>true</addClasspath>                            <classpathPrefix>lib/</classpathPrefix>                        </manifest>                        <manifestEntries>                            <Class-Path>.</Class-Path>                            <Built-By>yyc</Built-By>                            <Bundle-ManifestVersion>2</Bundle-ManifestVersion>                            <Bundle-Name>${project.groupId}.${project.ArtifactId}</Bundle-Name>                            <Bundle-SymbolicName>${project.groupId}.${project.ArtifactId}</Bundle-SymbolicName>                            <Bundle-Version>${project.version}</Bundle-Version>                            <Bundle-Vendor>${project.groupId}</Bundle-Vendor>                            <Import-Package>                                org.osgi.framework,org.slf4j,org.apache.camel,org.apache.cxf.message                            </Import-Package>                        </manifestEntries>                    </archive>                </configuration>            </plugin>        </plugins>    </build>

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