activiti是工作流，它可以实现一些请假或者面试等业务上的工作流，也可以实现ESB上一些服务编排，以便适应千变万化的互联网。

下面了解下他怎么和camel实现服务编排

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">   <service interface="org.activiti.camel.ContextProvider">        <bean class="org.activiti.camel.SimpleContextProvider">            <argument value="checkactiviti"/>            <argument ref="camelContext1"/>        </bean>    </service>        <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">        <property name="driverClassName" value="org.postgresql.Driver" />        <property name="url" value="jdbc:postgresql://192.168.1.100:5432/workflow1" />        <property name="username" value="xxx" />        <property name="password" value="xxxx" />    </bean>        <bean id="configurationFactory" class="org.activiti.osgi.blueprint.ConfigurationFactory">        <property name="dataSource" ref="dataSource"/>        <property name="databaseSchemaUpdate" value="true"/>    </bean>        <bean id="configuration" factory-ref="configurationFactory"  factory-method="getConfiguration"/>        <bean id="processEngineFactory" class="org.activiti.osgi.blueprint.ProcessEngineFactory" init-method="init" destroy-method="destroy">        <property name="processEngineConfiguration" ref="configuration"/>        <property name="bundle" ref="blueprintBundle"/>        <property name="blueprintELResolver" ref="blueprintELResolver"/>    </bean>        <bean id="processEngine" factory-ref="processEngineFactory" factory-method="getObject"/>    <bean id="identityService" factory-ref="processEngine" factory-method="getIdentityService"/>    <bean id="runtimeService" factory-ref="processEngine" factory-method="getRuntimeService"/>    <bean id="repositoryService" factory-ref="processEngine" factory-method="getRepositoryService"/>    <bean id="blueprintELResolver" class="org.activiti.osgi.blueprint.BlueprintELResolver"/>        <service ref="processEngine"  interface="org.activiti.engine.ProcessEngine"/>    <service ref="identityService" interface="org.activiti.engine.IdentityService"/>    <service ref="runtimeService" interface="org.activiti.engine.RuntimeService"/>    <service ref="repositoryService" interface="org.activiti.engine.RepositoryService"/>        <bean id="camel_bean" class="com.lala.activiti.CamelProcessor">    <property name="processEngine" ref="processEngine"/>    </bean>        <bean id="bean1" class="com.lala.bean.Bean1">        <property name="processEngine" ref="processEngine"/>         <property name="camelContext1" ref="camelContext1"/>            </bean>    <bean id="bean2" class="com.lala.bean.Bean2">         <property name="processEngine" ref="processEngine"/>               <property name="camelContext1" ref="camelContext1"/>    </bean>    <bean id="bean3" class="com.lala.bean.Bean3"></bean>        <camelContext id="camelContext1" xmlns="http://camel.apache.org/schema/blueprint">            <route id="activitidemo">            <from uri="acitivitiwg"/>            <to uri="activiti:checkactiviti"/>        </route>        <route id="cool1">            <from uri="activiti:checkactiviti:servicetask1" />            <to uri="bean:bean1"/>        </route>        <route id="cool2">            <from uri="activiti:checkactiviti:servicetask2?copyVariablesToProperties=true" />            <to uri="bean:bean2"/>        </route>    </camelContext></blueprint>

并且在src\main\resources\OSGI-INF\activiti\ 文件夹下面定义check.bpmn20.xml

<?xml version="1.0" encoding="UTF-8"?>             <definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:activiti="http://activiti.org/bpmn"  xmlns:bpmndi="http://www.omg.org/spec/BPMN/20100524/DI"  xmlns:omgdc="http://www.omg.org/spec/DD/20100524/DC"  xmlns:omgdi="http://www.omg.org/spec/DD/20100524/DI"             typeLanguage="http://www.w3.org/2001/XMLSchema"              expressionLanguage="http://www.w3.org/1999/XPath"              targetNamespace="http://www.activiti.org/test"><process id="checkactiviti" name="自动执行例子" isExecutable="true"><startEvent id="startevent1" name="自动执行"></startEvent><serviceTask id="servicetask1" name="一级转发" activiti:delegateExpression="${camel}"></serviceTask> <serviceTask id="servicetask2" name="二级转发" activiti:delegateExpression="${camel}"></serviceTask>                                <userTask id="usertask1" name="UserTask" activiti:delegateExpression="${camel}"></userTask>                <endEvent id="endevent1" name="结束"></endEvent><sequenceFlow id="flow1" sourceRef="startevent1" targetRef="servicetask1"></sequenceFlow><sequenceFlow id="flow2" sourceRef="servicetask1" targetRef="servicetask2"></sequenceFlow>                <sequenceFlow id="flow3" sourceRef="servicetask2" targetRef="usertask1"></sequenceFlow><sequenceFlow id="flow4" sourceRef="usertask1" targetRef="endevent1"></sequenceFlow></process></definitions>

bean1.java

public class Bean1 implements Processor {    private ProcessEngine processEngine;    private CamelContext camelContext1;    public void setProcessEngine(ProcessEngine processEngine) {        this.processEngine = processEngine;    }    public void setCamelContext1(CamelContext camelContext1) {        this.camelContext1 = camelContext1;    }        @Override    public void process(Exchange exchange) throws Exception {               exchange.getOut().setBody("sss");            }}

pom.xml需要导入依赖

<dependency>
<groupId>org.activiti</groupId>
<artifactId>activiti-camel</artifactId>
<version>5.16</version>
<scope>provided</scope>

</dependency>

<dependency>
<groupId>org.activiti</groupId>
<artifactId>activiti-osgi</artifactId>
<version>5.17.0</version>
<scope>provided</scope>
</dependency>

当然servicemix需要安装插件

<?xml version="1.0" encoding="UTF-8"?>
<features xmlns="http://karaf.apache.org/xmlns/features/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://karaf.apache.org/xmlns/features/v1.0.0 http://karaf.apache.org/xmlns/features/v1.0.0"
>

<feature name='features-activiti' version='1.0.0' install="auto">
<feature version='5.16.4'>activiti</feature>
</feature>

</features>
