java.lang.IllegalArgumentException: Update/delete queries cannot be typed

一：错误写法

String hql =  " delete from T_ST_CircuitMeterInfo e where e.circuitID = ?";

Query query = em.createQuery(hql, T_ST_CircuitMeterInfo.class);
query.setParameter(1, circuitID);

int count =  query.executeUpdate();

二：正解

String hql =  " delete  from T_ST_CircuitMeterInfo e where e.circuitID = ?";

Query query = em.createQuery(hql);

query.setParameter(1, circuitID);
int count =  query.executeUpdate();

delete语句执行createQuery的时候，不能传对象类。
