javaWeb->hql->in这个怎么做才是对的呀
StringBuilder hql = new StringBuilder("from Trade where ")
.append("shop = ? ")
.append("and workStatus in (?) ");
List<Object> paramsList = new ArrayList<Object>();
paramsList.add(trade.getShop());
List<WorkStatus> workStatusList = new ArrayList<WorkStatus>();
workStatusList.add(WorkStatus.CLIENT);
workStatusList.add(WorkStatus.FINANCIAL);
paramsList.add(workStatusList);//paramsList.add(workStatusList);后面这个也不行
tradeDao.findByHql(hql.toString(), paramsList.toArray());
报的异常都是in后面的这个?的类型转换错误。
java.lang.ClassCastException: java.util.ArrayList cannot be cast to java.lang.Enum
用注释掉的会报
java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to java.lang.Enum
at org.hibernate.type.EnumType.nullSafeSet(EnumType.java:148)
[解决办法]
当前，类型也应该正确。看样子in里面应该是数字类型，而不是你的EnumType类.
