以请假作为例子
1.通过部署模型,然后流程实例就创建成功了。
2.发起请假
发起请假,流程实例就启动起来了,启动的时候,相应的参数是在车传入的,比如,比如请假天数,用户判断后面流程的流向。
import lombok.AllArgsConstructor; import lombok.extern.slf4j.Slf4j; import org.springblade.core.log.exception.ServiceException; import org.springblade.core.mp.base.BaseServiceImpl; import org.springblade.core.secure.utils.SecureUtil; import org.springblade.core.tool.api.R; import org.springblade.core.tool.support.Kv; import org.springblade.core.tool.utils.DateUtil; import org.springblade.core.tool.utils.Func; import org.springblade.desk.entity.ProcessLeave; import org.springblade.desk.mapper.LeaveMapper; import org.springblade.desk.service.ILeaveService; import org.springblade.flow.core.constant.ProcessConstant; import org.springblade.flow.core.entity.BladeFlow; import org.springblade.flow.core.feign.IFlowClient; import org.springblade.flow.core.utils.FlowUtil; import org.springblade.flow.core.utils.TaskUtil; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; /** * 服务实现类 * * @author Chill */ @Slf4j @Service @AllArgsConstructor public class LeaveServiceImpl extends BaseServiceImplimplements ILeaveService { private IFlowClient flowClient; @Override @Transactional(rollbackFor = Exception.class) // @GlobalTransactional public boolean startProcess(ProcessLeave leave) { String businessTable = FlowUtil.getBusinessTable(ProcessConstant.LEAVE_KEY); if (Func.isEmpty(leave.getId())) { // 保存leave leave.setApplyTime(DateUtil.now()); save(leave); // 启动流程 Kv variables = Kv.create() .set(ProcessConstant.TASK_VARIABLE_CREATE_USER, SecureUtil.getUserName()) .set("taskUser", TaskUtil.getTaskUser(leave.getTaskUser())) .set("days", DateUtil.between(leave.getStartTime(), leave.getEndTime()).toDays()); R result = flowClient.startProcessInstanceById(leave.getProcessDefinitionId(), FlowUtil.getBusinessKey(businessTable, String.valueOf(leave.getId())), variables); if (result.isSuccess()) { log.debug("流程已启动,流程ID:" + result.getData().getProcessInstanceId()); // 返回流程id写入leave leave.setProcessInstanceId(result.getData().getProcessInstanceId()); updateById(leave); } else { throw new ServiceException("开启流程失败"); } } else { updateById(leave); } return true; } }
另外,在请假流程的xml中,我们发现了变了applyUser,applyUser是flowable引擎内部定义的发起人的参数名,代码位置:
@RestController @AllArgsConstructor public class FlowClient implements IFlowClient { private RuntimeService runtimeService; private IdentityService identityService; private TaskService taskService; @Override @PostMapping(START_PROCESS_INSTANCE_BY_ID) public RstartProcessInstanceById(String processDefinitionId, String businessKey, @RequestBody Map variables) { // 设置流程启动用户 identityService.setAuthenticatedUserId(TaskUtil.getTaskUser()); // 开启流程 ProcessInstance processInstance = runtimeService.startProcessInstanceById(processDefinitionId, businessKey, variables); // 组装流程通用类 BladeFlow flow = new BladeFlow(); flow.setProcessInstanceId(processInstance.getId()); return R.data(flow); }
然后就是“发起事物”,通过填写请假需要的信息,发起请假流程
进入控制搜索:start-process,查看启动流程,请假单据实体:public class ProcessLeave extends FlowEntity,对应数据库表blade_process_leave
3.第一次处理请假(人事审批)
发起请假的时候,指定了第一个处理的人。这个人登录的时候,在“待办事物”菜单查看
审批处理同意:blade-flow/work/complete-task
4.第二次处理请假(老板或者经理审批)
因为“发起请假”的时候,传入了请假天数,流程自动判断是老板还是经理审批
其他问题,xml流程中的相关变量,是如何设定的,同指定xml流程的时候,可以进入流程设计中具体看看
