JAVA监听类
以AssignTask为例，实现AssignmentHandler接口，即可在JPDL里应用监听
public class
AssignTask implements AssignmentHandler {
private static final long serialVersionUID = 1L;
@Override
public void assign(Assignable assignable, OpenExecution
execution)
throws Exception
{
//设置流程处理（受理）人
assignable.setAssignee("userA");
}
}
流程操作代码与前一章相同
部署流程
repositoryService.createDeployment().addResourceFromClasspath("com/tgb/node/task/task.jpdl.xml").deploy();
创建流程实例
//流程部署KEY
ProcessInstance processInstance =
executionService.startProcessInstanceByKey("task");
print("流程实例ID",processInstance.getId());
获取当前节点
//流程实例ID
String name =
executionService.createProcessInstanceQuery().processInstanceId("task.290001").uniqueResult().findActiveActivityNames().toString();
print("当前节点名词:",name);
获得任务列表
List<Task> tasks =
taskService.findPersonalTasks("A");
print("任务数量",tasks.size());
print("任务名词",tasks.get(0).getActivityName());
print("任务ID",tasks.get(0).getId());
完成任务
//任务ID
taskService.completeTask("290002");
