我编写了 creteria 查询，其中条件包括 and、or，也包含过滤条件的类似运算符。我的 creteria 查询执行在没有过滤条件的情况下运行良好。但如果我给出过滤条件，它会给我 NullPointerException。我已经引用了下面的链接，但它没有过滤条件
JPA 2.0 Criteria Query with Hibernate
Creteria查询代码:
List<TbiDDDetailView> tbiDDDetailViews = tbiDDDetailViewDao.findByDomainIdAndMetricNameLike(domainId, searchString);
CriteriaBuilder cb=em.getCriteriaBuilder();
CriteriaQuery<TbiDDDetailView> qry =cb.createQuery(TbiDDDetailView.class);
Root root = qry.from(TbiDDDetailView.class);
Root config = qry.from(TbiDDConfigMaster.class);
List<Order> orderList = new ArrayList<>();
orderList = getSort(cb,root,sortProperties, sortTypes, null);
qry.orderBy(orderList);
List creteriaList = new ArrayList<>();
Predicate predicate1 = cb.equal(root.get("tbiDDConfigMaster").get("ddConfigId"), config.get("ddConfigId"));
creteriaList.add(predicate1);
Predicate predicate2 = cb.equal(root.get("tbiDDConfigMaster").get("domainId"), domainId);
creteriaList.add(predicate2);
Predicate predicate3 = cb.or(cb.like(root.get("tbiDDConfigMaster").get("keywords"), "%"+searchString+"%"),cb.like(root.get("metricName"),"%"+searchString+"%"));
CriteriaQuery<TbiDDDetailView> criteriaQuery = qry.select(cb.construct(TbiDDDetailView.class, root.get("ddConfigId"),root.get("metricName"),root.get("ddType"),
root.get("ddName"),root.get("discoveryId"),root.get("keywords")));
//filter
Predicate filterCondition = cb.conjunction();
try {
Path<Integer> pathFilter = (Path<Integer>) getPath("isActive", root, null);
filterCondition=cb.and(cb.equal(pathFilter,"Y"));
filterCondition = getFilters(filterCondition, cb, root, property, operator, value, null);
} catch (JSONException e) {
e.printStackTrace();
log.info("Error In filter isActive", e);
}
qry.where(filterCondition,cb.and((Predicate[]) creteriaList.toArray(new Predicate[0])), predicate3);
TypedQuery<TbiDDDetailView> tq = em.createQuery(qry); //NullPointerException at this line
return tbiDDDetailViews = tq.getResultList();

普通MySql查询:
select d.* from tbi_datadiscovery_detail_view d join tbi_dd_config_master c on d.dd_metric_id = c.dd_metric_config_id
where c.domain_id = 1 and d.dd_metric_name like "%exp%" or d.key_words like "%exp%"
我已使用 Predicate 将这个 MySql 查询转换为 Creteria 查询。请让我知道我在使用过滤条件时哪里做错了
最佳答案
我已经找到了解决问题的方法。
问题是，我将 filterCondition 直接添加到 qry.where() 中，而不是我应该将其添加到 creteriaList 中，就像我正在做的那样其他谓词。
我的代码最后几行的更改(CriteriaQuery):
//filter
Predicate filterCondition = cb.conjunction();
try {
Path<Integer> pathFilter = (Path<Integer>) getPath("isActive", root, null);
filterCondition=cb.and(cb.equal(pathFilter,"Y"));
filterCondition = getFilters(filterCondition, cb, root, property, operator, value, null);
} catch (JSONException e) {
e.printStackTrace();
log.info("Error In filter isActive", e);
}
creteriaList.add(filterCondition);
Predicate predicate3 = (cb.or(cb.like(root.get("tbiDDConfigMaster").get("keywords"), "%"+searchString+"%"),cb.like(root.get("metricName"),"%"+searchString+"%")));
creteriaList.add(predicate3);
qry.where(cb.and((Predicate[]) creteriaList.toArray(new Predicate[0])));
关于java - JPA creteria 查询中的 NullPointerException(在 where 子句上带有过滤条件)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32351923/
