JBPM与SSH架构融合 

 

1．  加入spring-modules-jbpm31.jar

2．  在spirng中配置jbpmConfiguration

    <!-- jbpm configuration -->

    <bean id="jbpmConfiguration" class="org.springmodules.workflow.jbpm31.LocalJbpmConfigurationFactoryBean">

       <property name="sessionFactory" ref="sessionFactory" />

       <property name="configuration" value="classpath:jbpm.cfg.xml" />

    <!--   <property name="createSchema" value="true" />  -->

    </bean>

   

    <bean id="jbpmTemplate" class="org.springmodules.workflow.jbpm31.JbpmTemplate">

       <constructor-arg index="0" ref="jbpmConfiguration" />

    </bean>

    <!-- end jbpm configuration -->

 

2.如果Service中要用到工作流，将jbpmConfiguration注入到其属性中。

<bean id="xxxService" class="com.business.xxxServiceImpl">

       <property name="xxxDao">

           <ref bean="xxxDao" />

       </property>

       <property name="jbpmConfiguration">

           <ref bean="jbpmConfiguration" />

       </property>

    </bean>

3.如果想在项目部署时，就将流程自动部署到数据库中，则加上配置

<!-- reading jBPM process definitions -->

    <bean id="baoxiao"

       class="org.springmodules.workflow.jbpm31.definition.ProcessDefinitionFactoryBean">

       <property name="definitionLocation"

           value="classpath:com/workflow/flowchart/baoxiao/processdefinition.xml" />

    </bean>

    <bean id="caiwu"

       class="org.springmodules.workflow.jbpm31.definition.ProcessDefinitionFactoryBean">

       <property name="definitionLocation"

           value="classpath:com/workflow/flowchart/caiwu/processdefinition.xml" />

    </bean>

    <!-- jbpm configuration -->

    <bean id="jbpmConfiguration"

       class="org.springmodules.workflow.jbpm31.LocalJbpmConfigurationFactoryBean">

       <property name="sessionFactory" ref="sessionFactory" />

       <property name="configuration" value="classpath:jbpm.cfg.xml" />

       <property name="createSchema" value="true" />

       <property name="processDefinitions">  

           <list>

              <ref local="baoxiao" />

              <ref local="caiwu" />

           </list>

       </property>

    </bean>

 

    <bean id="jbpmTemplate"

       class="org.springmodules.workflow.jbpm31.JbpmTemplate">

       <constructor-arg index="0" ref="jbpmConfiguration" />

       <constructor-arg index="1" ref="baoxiao" />

       <constructor-arg index="1" ref="caiwu" />

    </bean>

    <!-- end jbpm configuration -->

 

4．配置workflow中action,assignment,decision等,同spring中普通的javaBean配置一样，采用依赖注入。

 

5.配置好后，在具体的processdefinition.xml中，引用这个类时，就有点区别：

   <assignment class="org.springmodules.workflow.jbpm31.JbpmHandlerProxy" config-type="bean">

            <targetBean>userAssignment</targetBean> 

            <factoryKey>jbpmConfiguration</factoryKey>

         </assignment>

<handler class="org.springmodules.workflow.jbpm31.JbpmHandlerProxy">

        <targetBean>processDecision</targetBean>

        <factoryKey>jbpmConfiguration</factoryKey>

     </handler>

 

  <action name="action1" class="org.springmodules.workflow.jbpm31.JbpmHandlerProxy">

         <targetBean>processResult</targetBean>

            <factoryKey>jbpmConfiguration</factoryKey>

         </action>

 

 

6.注意

config-type有4种配置类型：

1）Field------直接给目标类的字段赋值。 字段没有set/get方法，不是一个属性。该类也不是一个Bean。这应该是使用CGLIB字节码生成实现的。也可能使用反射。

<assignment class="com.withub.cms.jbpm.assignmenthandler.WriteNewsAssignmentHandler">

            <a>a</a>

         </assignment>

2）Bean------通过set方法赋值。   这和Spring的<property>是一致的。

<assignment class="com.withub.cms.jbpm.assignmenthandler.WriteNewsAssignmentHandler" config-type="bean">

            <a>a</a>

         </assignment>

3）constructor-----传给构造器的参数。

<assignment class="com.withub.cms.jbpm.assignmenthandler.WriteNewsAssignmentHandler" config-type="constructor">

            a

         </assignment>

4）compatibility-----兼容性

<assignment class="com.withub.cms.jbpm.assignmenthandler.WriteNewsAssignmentHandler" config-type="configuration-property">

            a

         </assignment>

默认的配置是默认的构造
