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");
