Question

升级后将Hibernate搜索4.3.0.Final升级到5.7.0.Final和当前的hibernate版本为5.2.6.Final

我遇到了以下异常

以下是提供异常的代码块

@Transactional(readOnly = true)
public <T> TextResults<T> performExclusionTextSearch(TextArgs<T> args)
{
    if (args != null && args.getSearchText() != null && args.getFromDate() != null && args.getToDate() != null
            && args.getFields() != null)
    {
        FullTextSession fullTextSession = Search.getFullTextSession(sessionFactory.getCurrentSession());
        QueryBuilder qb = getQueryBuilder(fullTextSession, args.getSearchEntity());

        try
        {
            // exclusion query
            Query query = qb
                    .bool()
                    .must(qb.keyword().onFields(args.getFields()).matching(args.getSearchText()).createQuery())
                    .not()
                    .must(qb.range().onField("captureDate").from(args.getFromDate()).to(args.getToDate())
                            .createQuery()).createQuery();

            FullTextQuery textQuery = fullTextSession.createFullTextQuery(query, args.getSearchEntity());

            // apply any filter
            if (args.getFilter() != null)
            {
                textQuery.enableFullTextFilter(args.getFilterClass()).setParameter(args.getFilterField(),
                        args.getFilter());
            }

            return runQuery(textQuery, args.getLimit());
        }
        catch (EmptyQueryException e)
        {
            // lucene standardanalyser filtered out the query word - ignore
        }
        return new TextResults<T>(false, new ArrayList<T>(0));
    }
    else
    {
        ManagementContext.logErrorEvent("Null parameters passed to text search");
        return new TextResults<T>(false, new ArrayList<T>(0));
    }
}

protected <T> TextResults<T> runQuery(FullTextQuery query, int limit)
{       
    boolean moreDataAvailable = false;

    //apply capturedate as a sorted field
    Sort sort = new Sort(new SortField("captureDate", SortField.Type.LONG, true));
    query.setSort(sort);

    int resultsize = query.getResultSize();

    if(resultsize > limit)
    {
        //return marker to indicate more results available
        moreDataAvailable = true;
        query.setMaxResults(limit);
    }

    @SuppressWarnings("unchecked")
    List<T> data = query.getResultList();   

    TextResults<T> results = new TextResults<>(moreDataAvailable, data);

    return results;
}

在runQuery方法中执行以下行时出错。

@SuppressWarnings("unchecked")
List<T> data = query.getResultList();

我的数据库是Oracle 11g。上面的代码工作正常，并通过Hibernate搜索4.3.0.Final提供有效的输出。

Answer 1

老实说，你正在更新这样一个古老的版本，我很惊讶你的应用程序甚至已经过去了：）

在尝试分析与搜索相关的失败之前，您应该做两件事：

确保您使用的是最近版本的Hibernate ORM。在这种情况下，它至少应该是ORM 5.2.3，我建议最新的（5.2.10，因为我正在写这篇文章）。
reindex your database completely。自4.3以来，Hibernate Search发生了很大的变化，因此您的旧索引不太可能与Hibernate Search 5.7一起使用。

Answer 2

虽然在从4.3.0.Final升级到5.7.0.Final期间调查类似问题，但发现了断言异常的可能原因： -

org.hibernate.search.exception.AssertionFailure: An entity got loaded even though it was not part of the EntityInfo list

当搜索条件中使用的类错误地重写其equals()和hashCode()方法以在身份而不是值上进行比较时，可能会抛出异常。这导致Hibernate代码的LinkedHashMap.put(key, value)方法无法找到它期望在映射中的临时代理对象（之前放置在那里），因为key将包含具有不同的对象实例相同的价值。
