프로세스 인스턴스의 위치를 ​​쿼리하는 방법은 무엇입니까?

Question

내 프로세스에서 단일 인스턴스의 현재 위치를 가져오고 싶습니다. id에 반환 값으로 액티비티의 이름을 추가 할 수 있습니까?

Answer 1

다음 코드를 사용하여 프로세스 인스턴스의 현재 위치를 알 수 있습니다. 그러면 프로세스가 여러 위치에서 대기 할 때 활동의 이름이 표시됩니다.

package org.camunda.bpm; 

import java.util.HashMap; 
import java.util.List; 
import java.util.Map; 
import org.camunda.bpm.engine.ProcessEngine; 
import org.camunda.bpm.engine.RepositoryService; 
import org.camunda.bpm.engine.RuntimeService; 
import org.camunda.bpm.engine.runtime.ProcessInstance; 
import org.camunda.bpm.model.bpmn.BpmnModelInstance; 
import org.camunda.bpm.model.xml.instance.ModelElementInstance; 

public class AllActiveActivities { 

    public Map<String, String> getAllActiveActivities(String processInstanceId) { 
    // get engine services 
    ProcessEngine processEngine = BpmPlatform.getDefaultProcessEngine() 
    RuntimeService runtimeService = processEngine.getRuntimeService(); 
    RepositoryService repositoryService = processEngine.getRepositoryService(); 

    // get the process instance 
    ProcessInstance processInstance = 
     runtimeService.createProcessInstanceQuery() 
      .processInstanceId(processInstanceId) 
      .singleResult(); 

    HashMap<String, String> activityNameByActivityId = new HashMap<String, String>(); 

    // get all active activities of the process instance 
    List<String> activeActivityIds = 
     runtimeService.getActiveActivityIds(processInstance.getId()); 

    // get bpmn model of the process instance 
    BpmnModelInstance bpmnModelInstance = 
     repositoryService.getBpmnModelInstance(processInstance.getProcessDefinitionId()); 

    for (String activeActivityId : activeActivityIds) { 
     // get the speaking name of each activity in the diagram 
     ModelElementInstance modelElementById = 
      bpmnModelInstance.getModelElementById(activeActivityId); 
     String activityName = modelElementById.getAttributeValue("name"); 

     activityNameByActivityId.put(activeActivityId, activityName); 
    } 

    // map contains now all active activities 
    return activityNameByActivityId; 
    } 

}
