프로세스 정의의 완성 된 인스턴스를 쿼리하는 방법은 무엇입니까?

Question

camunda 엔진이 완료된 모든 프로세스 인스턴스를 쿼리하는 API를 제공합니까?

Answer 1

다음과 같은 코드를 사용하여 프로세스의 모든 완성 된 인스턴스를 얻을 수 있습니다 :

package org.camunda.bpm; 

import org.camunda.bpm.engine.HistoryService; 
import org.camunda.bpm.engine.ProcessEngine; 
import org.camunda.bpm.engine.RepositoryService; 
import org.camunda.bpm.engine.history.HistoricProcessInstance; 
import org.camunda.bpm.engine.repository.ProcessDefinition; 
import java.util.List; 

public class AllFinishedProcessInstances { 

    public List<HistoricProcessInstance> getAllFinishedProcessInstances(String processDefinitionName) { 
    ProcessEngine processEngine = BpmPlatform.getDefaultProcessEngine(); 
    HistoryService historyService = processEngine.getHistoryService();; 
    RepositoryService repositoryService = processEngine.getRepositoryService(); 

    ProcessDefinition myProcessDefinition = 
     repositoryService.createProcessDefinitionQuery() 
      .processDefinitionName(processDefinitionName) 
      .latestVersion() // we are only interested in the latest version 
      .singleResult(); 

    List<HistoricProcessInstance> processInstances = 
     historyService.createHistoricProcessInstanceQuery() 
      .processDefinitionId(myProcessDefinition.getId()) 
      .finished() // we only want the finished process instances 
      .list(); 

    return processInstances; 
    } 

}
