jbpm4.4与Spring整合

与Spring的整合很简单:

  1)把事务交给Spring管理。

  2)通过Spring获取流程引擎ProcessEngine。

在项目的src目录下添加jbpm.cfg.xml文件:

<?xml version="1.0" encoding="UTF-8"?>
<jbpm-configuration>

  <import resource="jbpm.default.cfg.xml" />
  <import resource="jbpm.businesscalendar.cfg.xml" />
  <!-- <import resource="jbpm.tx.hibernate.cfg.xml" /> -->
  <!-- 与Spring整合使用 -->
  <import resource="jbpm.tx.spring.cfg.xml" />
  <import resource="jbpm.jpdl.cfg.xml" />
  <import resource="jbpm.bpmn.cfg.xml" />
  <import resource="jbpm.identity.cfg.xml" />

  <!-- Job executor is excluded for running the example test cases. -->
  <!-- To enable timers and messages in production use, this should be included. -->
  <!--
  <import resource="jbpm.jobexecutor.cfg.xml" />
  -->

</jbpm-configuration>

在Spring的配置文件applicationContext.xml添加如下配置:

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource" ref="myDataSource"/>
        <!-- 映射jbpm4.4的实体配置文件 -->
        <property name="mappingJarLocations">
               <value>WEB-INF/lib/jbpm.jar</value>
        </property>
        <property name="hibernateProperties">
          <value>
            hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
            <!-- 自动建表 -->
            hibernate.hbm2ddl.auto=update
          </value>
        </property>
   </bean>


<!-- jbpm4.4配置 -->
     <bean id="springHelper" class="org.jbpm.pvm.internal.processengine.SpringHelper">
              <property name="jbpmCfg" value="jbpm.cfg.xml"></property>
     </bean>
    
     <bean id="processEngine" factory-bean="springHelper" factory-method="createProcessEngine"/>
