jbpm4.3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());

            taskService.completeTask(task.getId());
        }
        
    }
