activiti流程變量的設置和獲取

流程變量的作用域依賴於流程實例，也就是在整個流程實例此流程變量是共享的

import org.activiti.engine.*;
import org.activiti.engine.repository.Deployment;
import org.activiti.engine.runtime.ProcessInstance;
import org.activiti.engine.task.Task;
import org.junit.Test;

public class ActivitiTest {
    //創建工作流引擎
    ProcessEngine processEngine= ProcessEngines.getDefaultProcessEngine();
    //管理任務節點的對象
    TaskService taskService=processEngine.getTaskService();

    /**
     * 設置流程變量
     */
    @Test
    public void setVariable(){
        //獲取當前流程實例id=10001的當前任務節點對象
        Task task= taskService.createTaskQuery().processInstanceId("10001").singleResult();
        //設置流程變量
        taskService.setVariable(task.getId(),"username","yl01");
        //完成此任務節點
        taskService.complete(task.getId());
    }

    /**
     * 獲取流程變量
     */
    @Test
    public void getVariable(){
        //獲取當前流程實例id=10001的當前任務節點對象
        Task task= taskService.createTaskQuery().processInstanceId("10001").singleResult();
        //設置流程變量
        String username= (String) taskService.getVariable(task.getId(),"username");
        System.out.println(username);
        //完成此任務節點
        taskService.complete(task.getId());
    }
