jbpm4.3与spring 集成

(参照http://www.blogjava.net/pengo/archive/2010/01/04/308219.html 做的)

下面是集成方法。

版本：
jbpm4.3
spring 3.0.2
mysql5.1.40

直接从jbpm4.4自带的文件到src目录:
从jbpm-4.4"install"src"cfg"hibernate"jdbc复制mysql.hibernate.cfg.xml到src目录，文件名改为hibernate.cfg.xml。
从jbpm-4.4"install"src"cfg"spring复制applicationContext.xml到src目录。
从jbpm-4.4"install"src"cfg"jbpm复制spring.jbpm.cfg.xml到src目录，文件名改为jbpm.cfg.xml。
修改applicationContext.xml、hibernate.cfg.xml的数据库配置信息，jbpm4.4与spring的集成就完成了，可以自己写测试文件测试，集成非常容易。

不过在applicationContext.xml和hibernate.cfg.xml两个文件都要改数据库信息有点麻烦，所以只复制 applicationContext.xml、spring.jbpm.cfg.xml两个文件到src目录，把hibernate.cfg.xml的配置整进spring的配置文件applicationContext.xml中。
applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<property name="url" value="${dataSource.url}" />
<property name="username" value="${dataSource.username}" />
<property name="password" value="${dataSource.password}" />
</bean>
</beans>

复制代码

新建文件hibernate.properties,主要用来配置连接数据库信息

dataSource.password=
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

复制代码

以后要改数据库配置信息也只在这个文件修改就可以了。

测试用的流程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>

测试代码
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();

      //发布流程
      String deploymentId = processEngine.getRepositoryService().createDeployment()
      .addResourceFromClasspath("resource/swing.jpdl.xml"

.deploy();
      System.out.println("流程发布ID:"+deploymentId);

      //启动一个流程实例
      ProcessInstance processInstance = executionService.startProcessInstanceByKey("swing"

;
      System.out.println("流程实例ID:" + processInstance.getId());

      //A处理任务
      List<Task> taskList_A = taskService.findPersonalTasks("A"

;
      System.out.println("A待处理任务数:" + taskList_A.size());
      if(taskList_A.size() > 0){
         Task task = taskList_A.get(0);
         taskService.completeTask(task.getId());
      }

      //B处理任务
      List<Task> taskList_B = taskService.findPersonalTasks("B"

;
      System.out.println("B待处理任务数:" + 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测试代码,仅在spring2.5.6测试过,要运行该部分代码,需要添加jbpm4.4和spring的相关依赖库文件参照.classpath时行添加。
