예약 된 작업과의 Confluence에서 UnUniqueObjectException이 발생했습니다

Question

은 페이지 생성과 관련하여 Quartz Job in Conluence에 큰 문제가 있습니다.

QUARTZ 작업 클래스 :

@ComponentImport 
private final SpaceManager spaceManager; 
@Autowired 
private final GeneralConfig config; 
@Autowired 
private final PageCreator pageCreator; 
@ComponentImport 
private final PageManager pageManager; 

@Autowired 
public ReportingPluginJob(GeneralConfig config, SpaceManager spaceManager, PageCreator pageCreator, 
     PageManager pageManager) { 
    this.config = config; 
    this.spaceManager = spaceManager; 
    this.pageCreator = pageCreator; 
    this.pageManager = pageManager; 
} 

private static final org.slf4j.Logger LOG = LoggerFactory.getLogger(ReportingPluginJob.class); 

@Override 
public void execute(JobExecutionContext jec) throws JobExecutionException { 

    Collection<String> keys = spaceManager.getAllSpaceKeys(SpaceStatus.CURRENT); 

    String parentPageName = config.getSchedulerWeeklyParentPageName(); 

    for (String key : keys) { 

     Page parentPage 
       = pageManager.getPage(key, parentPageName); 

     if (parentPage != null) { 
      LOG.debug("Creating weekly report for space " + key); 
      long pageId = parentPage.getId(); 
      try { 
       pageCreator.createEazyBiReport(key, pageId); 
      } catch (ApplicationException e) { 
       LOG.error("FAILED TO CREATE A REPORT FOR SPACE " + key + " with error: " + System.lineSeparator() 
         + e.getMessage()); 
      } 

     } 

    } 

} 

페이지 생성 클래스 :

Space space = spaceManager.getSpace(spaceKey); 

    if (page != null) { 
     page.setTitle(pageTitle); 
     page.setSpace(space); 
     page.setVersion(1); 
     page.addLabelling(new Labelling(label, page.getEntity(), AuthenticatedUserThreadLocal.get())); 
     page.setCreator(AuthenticatedUserThreadLocal.get()); 
     page.setCreationDate(new Date()); 
     Page parent = pageManager.getPage(parentId); 
     if (parent != null) { 
      parent.addChild(page); 
     } 
    } 
     pageManager.saveContentEntity(page, DefaultSaveContext.builder().suppressNotifications(true).build()); 
     attachmentProvider.attachExcelFileToPage(page);

는 스택 추적에 따르면, 내가 ' 페이지 저장 중 문제가 발생했습니다 (saveContentEntity). 그것은, 페이지 저장 너무 페이지와 관련된 공간을 업데이 트해야합니다 보인다. 그리고 여기에 문제가 있습니다. 스택 트레이스에 따르면,이 공간은 이미 Hibernate 세션에 존재한다. 실제 세션의 evict 및 clear이 작동하지 않습니다. 제안 사항, 어떻게이 예외를 처리 할 수 ​​있습니까? 아니면 실제로 최대 절전 모드 세션에서 공간을 제거 할 수 있습니까?

감사

Answer 1

는 분명히,이 코드에서 무슨 일이 일어나고 있는지입니다 : 내

1. 은 SpaceManager는 세션이 ID 1과 Session 객체 (즉, 가정)을 찾아 돌려줍니다.
2. 귀하의 방법은이 참조를 사용하여 다른 객체 인 Page과 연관시킵니다.
3. 그리고 마지막으로 PageManager은이 데이터를 데이터베이스에 유지합니다.

아마, 문제는 문제가 있음 :
1 단계의 SpaceManager 데이터를 반환 할 때, 거래가 종료하고 반환 된 객체가 detached됩니다 2,에.
그 후 save을 호출하면 분리 된 Session을 유지하려고 시도하지만 데이터베이스에 이미 있습니다. 그런 다음 예외가 발생합니다.

merge 메서드를 사용하거나 엔터티에서이 참조에서 cascade을 제거 할 수 있습니다.

이 (가 아무 잘못이 나있는 당신을 위해 작동하지 않는 경우 그래서 내 대답을 향상시킬 수 있습니다 엔터티 코드를 입력하십시오.)
