java.lang.ClassCastException: [Ljava.lang.Object; incompatible with com.shkco.adsr3.cbm.vo.ICustomerAccount
看到这错误都知道是数据类型转换不匹配,Object 与ICustomerAccount.
DAO 方法原始如下:
public List<ICustomerAccount> getListOfCustomerAccount(ISessionContext sessionContext, IClientCentricCustomer clientCentricCustomer) { ISessionWrapper session = getCurrentSession(); String sqlStr = "from " + CustomerAccount.class.getName() + " as cust join cust.companyGroup as cg where cg.compGrpId = " + ":companyGroupId " + " and cust.ccdRef= :ccdRef "; Query query = session.createQuery(sqlStr); query.setParameter("companyGroupId", getCompGrpId(sessionContext)); query.setParameter("ccdRef", clientCentricCustomer); return query.list(); }
没有注意看代码,因为是直接写的from .....没有写select 对象,所以返回的就是Object.
修改如下即可:
加上Select cust,即ICustomerAccount 对象就ok啦。
public List<ICustomerAccount> getListOfCustomerAccount(ISessionContext sessionContext, IClientCentricCustomer clientCentricCustomer) { ISessionWrapper session = getCurrentSession(); String sqlStr = "select cust from " + CustomerAccount.class.getName() + " as cust join cust.companyGroup as cg where cg.compGrpId = " + ":companyGroupId " + " and cust.ccdRef= :ccdRef "; Query query = session.createQuery(sqlStr); query.setParameter("companyGroupId", getCompGrpId(sessionContext)); query.setParameter("ccdRef", clientCentricCustomer); return query.list(); }
