将osworkflow集成到Spring环境中

osworkflow2.8提供了新的方式，将osworkflow集成到Spring环境中，并且使用Hibernate3持久化工作流状态。相关配置片断如下：

applicationContext.xml

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource"/>
</property>
<property name="hibernateProperties">
<ref bean="hibernateProperties"/>
</property>
<property name="mappingResources">
<list>

<!-- osworkflow mapping files -->

<value>com/opensymphony/workflow/spi/hibernate/HibernateCurrentStep.hbm.xml</value>

<value>com/opensymphony/workflow/spi/hibernate/HibernateHistoryStep.hbm.xml</value>

<value>com/opensymphony/workflow/spi/hibernate/HibernateWorkflowEntry.hbm.xml</value>

</list>

</property>



</bean>





<bean id="propertySetDelegate" class="com.opensymphony.workflow.spi.hibernate.DefaultHibernatePropertySetDelegate">

<property name="sessionFactory">

<ref bean="sessionFactory"/>

</property>

</bean>

<bean id="workflowStore" class="com.opensymphony.workflow.spi.hibernate3.NewSpringHibernateWorkflowStore">

<property name="sessionFactory">

<ref bean="sessionFactory"/>

</property>

<property name="propertySetDelegate">

<ref bean="propertySetDelegate"/>

</property>

</bean>

<bean id="workflowFactory" class="com.opensymphony.workflow.loader.SpringWorkflowFactory" init-method="init">

<property name="resource">

<value>workflows.xml</value>

</property>

<property name="reload">

<value>true</value>

</property></bean>

<bean id="workflowConfiguration" class="com.opensymphony.workflow.config.SpringConfiguration">

<property name="store">

<ref local="workflowStore"/>

</property>

<property name="factory">

<ref local="workflowFactory"/>

</property>

</bean>

<bean id="workflowTypeResolver" class="com.opensymphony.workflow.util.SpringTypeResolver">

</bean>

在应用代码中初始化工作流示例片断：

Workflow workflow = new BasicWorkflow(String caller);
workflow.setConfiguration(workflowConfiguration);
workflow.initialize(workflowName, 0, null);
