jpa返回List<Map<String, Object>>相当于jdbctemplate的queryForlist

public classTest(){
@PersistenceContext(unitName = "manageFactory")
protectedEntityManager em;
public List<Map<String, Object>>getListMap(String sql){
        Query nativeQuery=em.createNativeQuery(sql);
        nativeQuery.unwrap(NativeQueryImpl.class).setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP);
        List resultList=nativeQuery.getResultList();
        returnresultList;
        }
        }
