事件

开始事件：

initiator
流程启动人
通过identityService.setAuthenticatedUserId(startProcessBo.getUserId())设置的就是流程启东人

    public String startProcess(StartProcessBo startProcessBo) {
        identityService.setAuthenticatedUserId(startProcessBo.getUserId());
        ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(
                startProcessBo.getDefinitionKey(),
                startProcessBo.getBusinessKey(),
                startProcessBo.getVariables()
        );
        return processInstance.getProcessInstanceId();
    }

User Task

Assignee
任务处理人
Candidate groups
候选组
Candidate users
候选用户
Due date
到期日
Follow up date
跟进日期，是指任务的约定完成日期或截止日期。
有助于任务管理和优先级设定
Priority
优先级

send task

（1）在同一流程定义中发送消息

@Slf4j
@Component("sendMessage")
public class SendMessage implements JavaDelegate {
    @Override
    public void execute(DelegateExecution execution) throws Exception {
        execution.getProcessEngineServices().getRuntimeService()
                .createMessageCorrelation("messageName").processInstanceBusinessKey(execution.getBusinessKey()).correlate();
    }
}

（2）一个流程定义发送消息，另一个流程定义接收消息
启动流程

public class Test{
StartProcessBo startProcessBo = new StartProcessBo();     
startProcessBo.setBusinessKey(String.valueOf(carOrderCollectDetect.getOrderCollectId()));
startProcessBo.setDefinitionKey(carDetectDefinitionKey);
VariableMap variableMap = Variables.createVariables();
variableMap.put("test","test");
bpmFormService.startProcess(startProcessBo);
}

@Slf4j
@Component("sendMessageHandler")
public class SendMessageHandler implements JavaDelegate {

    @Override
    public void execute(DelegateExecution execution) throws Exception {

        execution.getProcessEngineServices().getRuntimeService()
                .createMessageCorrelation("messageName").processInstanceBusinessKey(execution.getBusinessKey()).correlate();

    }
}

会签

同一个审批节点，需要多个人审批：

会签：几个审批人，要全部同意

${nrOfInstances == nrOfCompletedInstances}

${nrOfCompletedInstances == nrOfInstances || !approve }

或签：几个审批人，只要有一个同意
${1 == nrOfCompletedInstances}
加签：增加审批人

runtimeService.createProcessInstanceModification(processInstanceId)
                .startBeforeActivity(activityId)
                .setVariable("user",user)
                .execute();

nrOfInstances 实例的数目
nrOfCompletedInstances 完成实例的数目
nrOfActiveInstances 未完成实例的数目
loopCounter 循环计数器，办理人在列表中的索引。
