我正在使用CriteriaQuery创建具有特定类类型的TypedQuery。 而且我只需要类类中的几列。 我正在通过multiselect方法选择这些列，但我正在努力处理下面的RuntimeException。 这是说系统不能罚款构造函数。 但是，我创建了构造函数。CriteriaQuery multiselect - 运行时构造函数错误
请给我关于这个问题的建议。
用条件创建查询。
CriteriaBuilder criteriaBuilder = getEntityManager().getCriteriaBuilder();
CriteriaQuery<VwLocationBrief> criteriaQuery = criteriaBuilder.createQuery(VwLocationBrief.class);
Root<VwLocationBrief> root = (Root<VwLocationBrief>) criteriaQuery.from(VwLocati onBrief.class);
CriteriaHelper<VwLocationBrief> criteriaHelper = criteriaHelperFactory.newCriteriaHelper(criteriaBuilder, root);
criteriaHelper.ignoreCaseLike(CONTACT_NAME, locationAdvancedSearchCriteria.getContactName())
.ignoreCaseEq(CONTACT_EMAIL, locationAdvancedSearchCriteria.getEmailaddress())
.ignoreCaseLike(LOCATION_NAME2, locationAdvancedSearchCriteria.getLocationName())
.ignoreCaseLike(UNIT_NAME, locationAdvancedSearchCriteria.getUnitName())
.ignoreCaseLike(LOCATION_CODE, locationAdvancedSearchCriteria.getLocationCode())
.ignoreCaseAndSpaceSuffixLike(POSTCODE, locationAdvancedSearchCriteria.getPostcode() != null ? locationAdvancedSearchCriteria.getPostcode().replaceAll(" ", "") : null)
.orderBy(LOCATION_NAME2, CriteriaHelper.ASCENDING);
//Here are the columns that I want to select
**criteriaQuery.multiselect(
root.get(ADDRESS_LINE1),
root.get(ADDRESS_LINE2),
root.get(ADDRESS_LINE3),
root.get(ADDRESS_LINE5),
root.get("businessName"),
root.get(BRN_PARAM),
root.get(LOCATION_CODE),
root.get("locationId"),
root.get(LOCATION_NAME),
root.get("mainLocation"),
root.get(POST_TOWN),
root.get(POSTCODE))
.distinct(true);**
criteriaQuery.where(criteriaHelper.getPredicates());
if(type != null && type.equals("list")) {
criteriaQuery.orderBy(criteriaHelper.getOrdering());
}
这里是构造函数。
public VwLocationBrief(String addressLine1, String addressLine2,
String addressLine3, String addressLine5, String businessName,
long brn, String locationCode, long locationId,
String locationName, boolean mainLocation, String postTown,
String postcode) {
this.addressLine1 = addressLine1;
this.addressLine2 = addressLine2;
this.addressLine3 = addressLine3;
this.addressLine5 = addressLine5;
this.businessName = businessName;
this.brn = brn;
this.locationCode = locationCode;
this.locationId = locationId;
this.locationName = locationName;
this.mainLocation = mainLocation;
this.postTown = postTown;
this.postcode = postcode;
}
这是我得到的例外。

我已经创建了构造函数。 有人可以让我现在我有什么运行时错误？
所以用确切的消息陈述异常和堆栈跟踪 –
@NeilStockton你好，谢谢。我对理解英语有限制。你是否意味着要把整个异常信息？ –
是的。调用“e.printStackTrace（）”并将其添加到您的问题 –
