我正在使用elasticsearch,我试图处理数据库为空的情况
@SuppressWarnings("unchecked")
public <M extends Model> SearchResults<M> findPage(int page, String search, String searchFields, String orderBy, String order, String where) {
BoolQueryBuilder qb = buildQueryBuilder(search, searchFields, where);
Query<M> query = (Query<M>) ElasticSearch.query(qb, entityClass);
// FIXME Currently we ignore the orderBy and order fields
query.from((page - 1) * getPageSize()).size(getPageSize());
query.hydrate(true);
return query.fetch();
}
return query.fetch() 处的错误;
我正在尝试实现一个 try and catch 语句,但它不起作用,任何人都可以帮助解决这个问题吗?
