1、查询指定字段

     public List<Object[]> getUseList( Integer index, Integer offset, String state, String search ){

            String sqlSelect = "select user_id, user_name ";
            String sql = sqlSelect + " from users where user_status in (:state) limit :index, :offset";

                SQLQuery sqlQuery = sessionFactory.getCurrentSession().createSQLQuery(sql);
                
                sqlQuery.setInteger("index", index);
                sqlQuery.setInteger("offset", offset);

                String [] stateList = state.split(",");
                sqlQuery.setParameterList("state", stateList);

                search =  "%" + search + "%";
                sqlQuery.setString("userName", search);

                List<Object[]> restList = sqlQuery.list();
            
                return restList;
            }

获取结果集

for(Object[] restArr : restList){
                Map<String, Object> userMap = new HashMap<>();
                Integer userId = (Integer) restArr[0];
                String userName =  (String) restArr[1];
}
