Jbpm4.4 与spring集成

注：实现的过程中，一开始Spring的版本采用的是3.0.1的集成测试的时候会报：

tried to access method org.springframework.orm.hibernate3.SessionFactoryBuil......

的异常信息，最后改为2.5的版本即可。

1. jbpm的配置

2. <?xml version="1.0" encoding="UTF-8"?>
   
   <jbpm-configuration>
   
     <import resource="jbpm.default.cfg.xml" />
     <import resource="jbpm.businesscalendar.cfg.xml" />
     <!--
     	jbpm 与spring集成时，需要将事务管理交给spring 
     	<import resource="jbpm.tx.hibernate.cfg.xml" /> 
     -->
     <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>

4. 测试

   @Test
       public void testSpring(){
           try {
               ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
               ProcessEngine pe = (ProcessEngine) ac.getBean("processEngine");
               HistoryService hs = pe.getHistoryService();
               //查看系统中定义的流程的历史流程实例信息
               List<HistoryProcessInstance> hpis = hs.createHistoryProcessInstanceQuery().processDefinitionId("demo-1").list();
               for (HistoryProcessInstance historyProcessInstance : hpis) {
                   System.out.println(historyProcessInstance.getProcessInstanceId());
               }
           } catch (BeansException e) {
               e.printStackTrace();
           }
       }
