Question

[当我尝试将实体持久化到数据库中时，出现以下错误消息：

我给出错误的方法：

public Result saveFilterHierarchy(List<Filter> filters) {
        EntityTransaction transaction = null;
        EntityManager entityManager = null;
        Result result = new Result();
        try {
            entityManager = createEntityManager();
            if (entityManager != null) {

                if (filters != null && !filters.isEmpty())
                    for(int i = 0; i < filters.size(); i++) {
                        logger.error("Filter ready: {}", filters.get(i));
                        if(filters.get(i).getId() == null) {
                            transaction = entityManager.getTransaction();
                            transaction.begin();
                            initDatabaseSession(entityManager);
                            logger.error("Filter saved: {}", filters.get(i));
                            entityManager.flush();
                            entityManager.persist(filters.get(i));
                            transaction.commit();
                        }
                    }
                }
        } catch (Exception ex) {
            logger.error("Transaction error: {}", ex);
        } finally {
            closeEntityManager(entityManager);
        }
        return result;
    }

什么可能导致此错误？
