jbpm 4.3 与 spring 集成

jbpm4.2与spring集成有点问题，直接跟据它自己的“开发指南”提供的方法是不能集成的。在官网查到的信息是发布4.2时，忘记更新集成spring的文件。不过4.3已经把该bug改过来了。下面是集成方法。

版本：
jbpm4.3
spring2.5.6
mysql5.1.40

直接从jbpm4.3自带的文件到src目录:
从jbpm-4.3"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-4.3"install"src"cfg"spring复制applicationContext.xml到src目录。
从jbpm-4.3"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，jbpm4.3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

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

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jbpm4.3和spring的相关库文件。
