Activiti7的通用功能

删除部署流程
挂起或激活流程
获取流程的所有节点的人员信息
获取流程的历史审核记录
处理task的通用方法

删除部署流程

    /**
     * 删除部署流程
     * @param deploymentId
     */
    void deleteDeployment(String deploymentId){
        repositoryService.deleteDeployment(deploymentId);
    }

挂起或激活流程

    /**
     * 挂起或激活部署流程
     * @param processDefinitionId
     */
    void suspendProcessDefinition(String processDefinitionId){
        ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery()
                .processDefinitionId(processDefinitionId).singleResult();
        if (processDefinition.isSuspended()){
            repositoryService.activateProcessDefinitionById(processDefinitionId);
        }else {
            repositoryService.suspendProcessDefinitionById(processDefinitionId);
        }
    }

获取流程的所有节点的人员信息

    /**
     * 获取流程节点人员方法，人员名称按照user1,user2,user3...依次类推
     * @param num
     * @param instanceId
     * @return
     */
    List<String> getVariablesUsers(int num,String instanceId){
        Map<String,String> map = Maps.newHashMap();
        List<String> users = Lists.newArrayList();
        for(int i = 1 ; i<=num; i++){
            String name = "user"+i;
            map.put(name,"");

        List<HistoricVariableInstance> historicVariableInstances = historyService
                .createHistoricVariableInstanceQuery()
                .processInstanceId(instanceId)
                .list();

                    b=false;
                    break;
                }
            }
            if (b){
                break;
            }
        }
        for(int i = 1 ; i <=num ; i++){
            users.add(map.get("user"+i));
        }

获取流程的历史审核记录

        }

    }

处理task的通用方法

    /**
     * 处理task方法
     * @param instanceId
     * @param result
     * @param comment
     */
    void dealTask(String instanceId,String result,String comment){
        Task task = taskService.createTaskQuery().processInstanceId(instanceId).taskAssignee(RequestHolder.getCurrentUser().getUsername()).singleResult();
        String taskId ="";
        if (task!=null){
            taskId = task.getId();
            /**
             * 单个流程的变量使用setVariableLocal(taskId,paramName,paramValue)
             */
            taskService.setVariableLocal(taskId,"result",result);

            if (comment!=null){
                taskService.addComment(taskId,instanceId,comment);
            }
            taskService.complete(taskId);
        }
    }
