java数据库resultset取值是地址而不是数据库存的数据

ResultSetMetaData metaData = resultSet.getMetaData();
List> rows = new ArrayList>();
while (resultSet.next()) {
Hashtable row = new Hashtable();
for (int i = 1; i <= metaData.getColumnCount(); i++) {
System.out.println(metaData.getColumnName(i));
row.put(metaData.getColumnName(i), resultSet.getObject(i));
}
resultSet.getobject(i)从数据库取出的值是地址，而我从数据库中查的是数字0
