activiti 使用

activiti使用：最近公司要做一个项目，使用工作流，但是也没有人会，只好自己去研究研究。本人菜鸟一个使用的方法有可能狠低级勿喷啊。欢迎指正！研究时间只有4天＝＝！

activiti的配置文件：

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	<!-- 流程引擎 -->
	<bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">
		<property name="processEngineConfiguration" ref="processEngineConfiguration" />
	</bean>
	

	<!-- 由流程引擎对象，提供的方法，创建项目中使用的Activiti工作流的Service -->
	<bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService" />
	<bean id="runtimeService" factory-bean="processEngine" factory-method="getRuntimeService" />
	<bean id="taskService" factory-bean="processEngine" factory-method="getTaskService" />

	<bean id="managementService" factory-bean="processEngine" factory-method="getManagementService" />
	
</beans>

工作流的话也就涉及到待办，已办，新建任务什么的了。

查询待办的代码：

/**
	 * 查询待办分页数据
	 * @param page 分页对象
	 * @param taskManager
	 * @return
	 */
	public Page<Map<String, Object>> findMissionPage(String taskId, String taskName) {

		List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
		Page<Map<String, Object>> result = new Page<Map<String, Object>>();

		// 创建查询对象
		NativeTaskQuery taskQuery = taskService.createNativeTaskQuery();
		StringBuffer sb = new StringBuffer();
		sb.append("SELECT * FROM " + managementService.getTableName(Task.class)+" H WHERE H.CREATE_TIME_ IS NOT NULL AND H.PROC_INST_ID_ IS NOT NULL AND H.ASSIGNEE_ = #{userCode}");
		taskQuery.parameter("userCode", UserUtils.getUser().getUserCode());
		
		if(StringUtils.isNotBlank(taskId)){
			sb.append(" and H.PROC_INST_ID_ LIKE #{taskId}");
			taskQuery.parameter("taskId", "%"+taskId+"%");
		}
		
		// 设置排序 字段，根据任务创建时间降序
		sb.append(" ORDER BY H.CREATE_TIME_ DESC");
		
		// 执行sql
		taskQuery.sql(sb.toString());

		// 获取查询列表
		List<Task> taskLst = taskQuery.list();
		
		WorkflowService workflowService = new WorkflowService();
		Map<String, String> processNames = workflowService.findDeploymentList();
		Map<String, String> resourceMap = ResourceUtils.getResource("jkyprocessflow").getMap();
		
		for (Task task : taskLst) {
			
			TaskRes taskRes = new TaskRes();
			taskRes.setProcessInstanceId(task.getProcessInstanceId());
			TaskRes taskResInfo = taskResDao.get(taskRes);
			
			String pid = workflowService.findDeploymentid(task.getProcessDefinitionId()).getDeploymentId();
			if(StringUtils.isNotBlank(taskName)){
				if(!(processNames.get(pid)).contains(taskName)){
					continue;
				}
			}
			Map<String,Object> map = new HashMap<String,Object>();
			String processInstanceId = task.getProcessInstanceId();
			map.put("id", task.getId());
			map.put("processName", processNames.get(pid));
			map.put("name", task.getName());
			map.put("createTime", task.getCreateTime());
			map.put("assignee", UserUtils.get(task.getAssignee()).getUserName());
			map.put("processInstanceId", processInstanceId);
			map.put("executionId", task.getExecutionId());
			map.put("resCode", taskResInfo==null ? "" : taskResInfo.getResCode());
			map.put("serviceCode", taskResInfo==null ? "" : taskResInfo.getBusinessCode());
			map.put("processDefinitionId", task.getProcessDefinitionId());
			map.put("instanceStatus", (workflowService.processIsEnd(processInstanceId)) == true ? "运行中":"完成");
			
			// 维护流程
			if(resourceMap.get("maintenanceProcessDefinitionPid").equals(pid)){
				if("提交表单".equals(task.getName())){
					map.put("formUri", "/instru/maService/commit");
				}else{
					map.put("formUri", "/instru/maService/form");
				}
			}
			// 维修流程
			else if(resourceMap.get("repairProcessDefinitionPid").equals(pid)){
				if("提交表单".equals(task.getName())){
					map.put("formUri", "/instru/maintain/commit");
				}else{
					map.put("formUri", "/instru/maintain/maform");
				}
			}
			//
