flowable流程引擎开发记录

• 根据流程定义ID和发起人，获取流程实例。还可以区分其中运行和结束。通过endTime是否为空判断

获取全部

String userIdStr = TaskUtils.getUserId();
List<HistoricProcessInstance> historicProcessInstances =
    historyService.createHistoricProcessInstanceQuery().processDefinitionId(procDefId).startedBy(userIdStr).list();
if (CollUtil.isNotEmpty(historicProcessInstances)) {
    throw new ServiceException("请勿重复发起流程.");
}

• 查询条件的使用

1. 使用businessKey查询。精确和模糊查询两种

String businessKey = "project-12345:user001";
List<HistoricProcessInstance> instances = historyService.createHistoricProcessInstanceQuery()
    .processInstanceBusinessKeyLike("project-12345:%") // 匹配所有该项目下的申请
    .list();

boolean hasApplied = !historyService.createHistoricProcessInstanceQuery()
    .startedBy("user001")
    .processInstanceBusinessKey("project-12345:user001")
    .list().isEmpty();

if (hasApplied) {
    throw new ServiceException("您已为此项目发起过流程");
}

2. 使用条件组合查询

variables.put("projectId", "12345");
variables.put("applicantId", "user001");
variables.put("patientSysUserId", "patient-001");


List<HistoricProcessInstance> instances = historyService.createHistoricProcessInstanceQuery()
    .processVariableValueEquals("projectId", "12345")
    .processVariableValueEquals("applicantId", "user001")
    .list();
