获取流程发起人

• 通过当前实例获取

// 流程发起人
ProcessInstance processInstance = runtimeService.createProcessInstanceQuery()         .processInstanceId(execution.getProcessInstanceId())
                .singleResult();
String startUserId = processInstance.getStartUserId();

• 通过历史任务

// 获取流程发起人
HistoricProcessInstance hi = historyService.createHistoricProcessInstanceQuery().processInstanceId(execution.getProcessInstanceId())
                .singleResult();
String startUserId = hi.getStartUserId();

设置流程发起人

//设置流程发起人
Authentication.setAuthenticatedUserId(userId);
ProcessInstance processInstance =  runtimeService.startProcessInstanceByKey(procdefKey,businessKey, paras);
// 重置为空
Authentication.setAuthenticatedUserId(null);

获取某个人发起的流程

List<HistoricProcessInstance> list = historyService.createHistoricProcessInstanceQuery()
        .startedBy(userId)
        .orderByProcessInstanceStartTime()
        .list();
