activiti7中流程实例的挂起和激活

谁借莪１个温暖的怀抱￠ 2023-01-02 07:29 208阅读 0赞

如下代码可以实现流程实例的挂起和激活

但是里面有一个坑

activateProcessDefinitionById和suspendProcessDefinitionById方法中的第三个参数是要填写时间

我填写了new Date()

然后就修改不成功

只能写null才能过去

这个坑先留着

//对流程定义来进行全部流程实例的挂起和激活
    //假如到月底我不做处理出差申请了,那么就把所有的出差审批都给挂起,月初了我再全部激活
    @Test
        public void suspendAllProcessInstance() {
            //1.获取引擎
            ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
            //2.获取repositoryService
            RepositoryService repositoryService = processEngine.getRepositoryService();
            //3.查询流程定义, 获取流程定义的查询对象来查询
            ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery()
                    .processDefinitionKey("myEvection")
                    .singleResult();
            //4.查询当前流程定义的实例是否都是挂起状态
            //获取当前实例是否是挂起状态,对应的表中字段1为true,2位false
            boolean suspended = processDefinition.isSuspended();
            //5.获取流程定义id
            String definitionId = processDefinition.getId();
            //6.如果是挂起状态,改为激活状态
            if (suspended) {
                repositoryService.activateProcessDefinitionById(definitionId, true, null);
                System.out.println(definitionId + "已激活");
    
            } else {
                //7.如果是激活状态,则改为挂起状态
                //参数1是流程定义的id,参数2是是否要激活,参数3是激活时间
                repositoryService.suspendProcessDefinitionById(definitionId, true, null);
                System.out.println(definitionId + "已挂起");
            }
    
        }
       
    
    
    //单人的流程实例的挂起和激活
        @Test
        public void suspendOneProcessInstance(){
            //1.获取引擎
            ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
            //2.获取runtimeService
            RuntimeService runtimeService = processEngine.getRuntimeService();
            //3.获取流程实例的id
            ProcessInstance processInstance = runtimeService.createProcessInstanceQuery()
                    .processInstanceId("10001")
                    .singleResult();
            //4.获取流程实例的状态
            boolean suspended = processInstance.isSuspended();
            //5.获取流程实例id
            String id = processInstance.getId();
            System.out.println("流程实例id:" + id);
    
            if (suspended){
                runtimeService.activateProcessInstanceById(id);
                System.out.println("流程实例id:" + id +"激活");
            }else{
                runtimeService.suspendProcessInstanceById(id);
                System.out.println("流程实例id:" + id +"挂起");
            }
    
        }
