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。
