> getDbType(){ String sql = "select * from student"; List
> list = jdbcTemplate.queryForList(sql); for (Map
map : list) { Set
> entries = map.entrySet( ); if(entries != null) { Iterator
> iterator = entries.iterator( ); while(iterator.hasNext( )) { Map.Entry
entry =(Map.Entry
) iterator.next( ); Object key = entry.getKey( ); Object value = entry.getValue(); System.out.println(key+":"+value); } } } return list; } }
