Activiti'de program örneği olarak bir işlem örneği nasıl silinir/askıya alınır?

Question

Bir İşlem Motoru, Depo Hizmeti, Çalışma Zamanı Hizmeti oluşturdum ve bir BPMN iş akışı dağıtdım. Ayrıca bir İşlem örneği oluşturdum ve başlatabiliyordum. Sorun, "deleteProcessInstance" yöntemini kullanarak işlem örneğini askıya almayı veya silmeyi denediğimde, ProcessInstanceId bulunamadığını belirten bir hata alıyorum !! PS: BPMN'deki processId'nin Activiti'de processKey olarak ele alındığını öğrendim.

Kodu: işlem örneğini başlarken Yukarıdaki kodu

public void startProcess(String processDefinitionKey) 
    { 

     ListenerClass.processInstance= ListenerClass.runtimeService.startProcessInstanceByKey(processDefinitionKey); 

    } 

    public void deleteProcess(String processInstanceId) 
    { 


      System.out.println("Stopping Process instance id " +processInstanceId); 

      ListenerClass.runtimeService.deleteProcessInstance(processInstanceId, "Ok"); 



    } 

} 

ben BPMN.xml dosyasının "işlem kimliği" geçiş (BPMN.xml arasında ProcessID activiti ait = processInstanceKey anlamına gelir).

bu bağlamda herhangi bir yardım gerçekten yararlı olacaktır.

runtimeService.deleteProcessInstance(processInstanceId, null); 

süreç, belki işlem zaten sona erdi geçmiş silmek için ihtiyaç bitirildiginde: Yukarıda olduğu gibi bir koşu işlemi için

Answer 1

, bunu kullan?

HistoricProcessInstance historicProcessInstance = historyService.createHistoricProcessInstanceQuery() 
     .processInstanceId(processInstanceId).singleResult(); 
if (historicProcessInstance != null) { 
    historyService.deleteHistoricProcessInstance(historicProcessInstance.getId()); 
}
