JeecgBoot 里两个流程引擎，你用对了吗？

@Service
public class BizTripProcessService {

    @Autowired
    private FlowableProcessService flowableService;  // Flowable 流程服务

    @Autowired
    private CollaborativeWorkService collaborativeService;  // 协同工作服务

    /**
     * 发起出差审批——根据流程类型分流到不同引擎
     * @param tripId  出差申请ID
     * @param processType  "flowable" 或 "collaborative"
     * @param nextAssignee  协同工作模式下，下一步审批人账号
     */
    public void startProcess(String tripId, String processType, String nextAssignee) {
        if ("flowable".equals(processType)) {
            // Flowable：流程图已预部署，按定义key启动
            // 流程定义中已绑定各节点角色，不需要手动指定审批人
            flowableService.startProcessByKey("biz_trip_flowable", tripId);
        } else if ("collaborative".equals(processType)) {
            // 协同工作：无预定义流程，发起时指定第一个审批人
            collaborativeService.startAdhocProcess(
                "biz_trip", tripId, nextAssignee
            );
        } else {
            throw new IllegalArgumentException("未知的流程类型: " + processType);
        }
    }
}
