jbpm4.2與spring集成有點問題，直接跟據它自己的“開發指南”提供的方法是不能集成的。在官網查到的信息是發布4.2時，忘記更新集成spring的文件。不過4.3已經把該bug改過來了。下面是集成方法。

版本：
jbpm4.3
spring2.5.6
mysql5.1.40

直接從jbpm4.3自帶的文件到src目錄:
從jbpm-4.3"install"src"cfg"hibernate"jdbc復制mysql.hibernate.cfg.xml到src目錄，文件名改為hibernate.cfg.xml。
從jbpm-4.3"install"src"cfg"spring復制applicationContext.xml到src目錄。
從jbpm-4.3"install"src"cfg"jbpm復制spring.jbpm.cfg.xml到src目錄，文件名改為jbpm.cfg.xml。
修改applicationContext.xml、hibernate.cfg.xml的數據庫配置信息，jbpm4.3與spring的集成就完成了，可以自己寫測試文件測試，集成非常容易。

不過在applicationContext.xml和hibernate.cfg.xml兩個文件都要改數據庫信息有點麻煩，所以只復制applicationContext.xml、spring.jbpm.cfg.xml兩個文件到src目錄，把hibernate.cfg.xml的配置整進spring的配置文件applicationContext.xml中。
applicationContext.xml

新建文件hibernate.properties,主要用來配置連接數據庫信息

dataSource.password=123
dataSource.username=root
dataSource.databaseName=jbpmdb
dataSource.driverClassName=com.mysql.jdbc.Driver
dataSource.dialect=org.hibernate.dialect.MySQLInnoDBDialect
dataSource.serverName=localhost:3306
dataSource.url=jdbc:mysql://${dataSource.serverName}/${dataSource.databaseName}
dataSource.properties=user=${dataSource.username};databaseName=${dataSource.databaseName};serverName=${dataSource.serverName};password=${dataSource.password}
dataSource.hbm2ddl.auto=update

以后要改數據庫配置信息也只在這個文件修改就可以了。

測試用的流程swing.jpdl.xml

<?xml?version="1.0"?encoding="UTF-8"?>
<process?name="swing"?xmlns="http://jbpm.org/4.3/jpdl">
???<start?g="94,64,48,48"?name="start1">
??????<transition?g="-52,-22"?name="A"?to="A"/>
???</start>
???<task?assignee="A"?g="73,195,92,52"?name="A">
??????<transition?g="-52,-22"?name="B"?to="B"/>
???</task>
???<task?assignee="B"?g="266,192,92,52"?name="B">
??????<transition?g="-40,-21"?name="end"?to="end1"/>
???</task>
???<end?g="290,327,48,48"?name="end1"/>
</process>

測試代碼

public?class?Main?{
????public?static?void?main(String[]?args)??{
????????ClassPathXmlApplicationContext?applicationContext?=?new?ClassPathXmlApplicationContext("applicationContext.xml");
????????applicationContext.start();
????????ProcessEngine?processEngine?=?(ProcessEngine)applicationContext.getBean("processEngine");
????????ExecutionService?executionService?=?processEngine.getExecutionService();
????????TaskService?taskService?=?processEngine.getTaskService();

????????//發布流程
????????String?deploymentId?=?processEngine.getRepositoryService().createDeployment()
????????.addResourceFromClasspath("resource/swing.jpdl.xml").deploy();
????????System.out.println("流程發布ID:"+deploymentId);
????????
????????//啟動一個流程實例
????????ProcessInstance?processInstance?=?executionService.startProcessInstanceByKey("swing");
????????System.out.println("流程實例ID:"?+?processInstance.getId());

????????//A處理任務
????????List<Task>?taskList_A?=?taskService.findPersonalTasks("A");
????????System.out.println("A待處理任務數:"?+?taskList_A.size());
????????if(taskList_A.size()?>?0){
????????????Task?task?=?taskList_A.get(0);
????????????taskService.completeTask(task.getId());
????????}
????????
????????//B處理任務
????????List<Task>?taskList_B?=?taskService.findPersonalTasks("B");
????????System.out.println("B待處理任務數:"?+?taskList_B.size());
????????if(taskList_B.size()?>?0){
????????????Task?task?=?taskList_B.get(0);
????????????taskService.completeTask(task.getId());
????????}
????????
????}
}

附件是完整的集成文件和測試代碼,僅在spring2.5.6測試過,要運行該部分代碼,需要添加jbpm4.3和spring的相關庫文件。
源代碼:jbpm4.3-spring
