一些小记

List rs1 = this.jdbcTemplate.queryForList("select count(*) as counter from (" + sqlString + ")",obj);
if (rs1 != null && !rs1.isEmpty() && rs1.size() > 0) {
　　ListOrderedMap map = (ListOrderedMap) rs1.iterator().next();
　　pagenator.setCount(((BigDecimal) map.getValue(0)).intValue());
} else {
　　pagenator.setCount(0);}
