使用JDBC连接数据库，查询结果转成List或者Map(臃肿版)： http://my.oschina.net/zhengweishan/blog/484377
这个感觉不是很好：然后改成下面的这种方式：
public static List<Map<String, Object>> convertList(ResultSet rs) {
List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
try {
ResultSetMetaData md = rs.getMetaData();
int columnCount = md.getColumnCount();
while (rs.next()) {
Map<String, Object> rowData = new HashMap<String, Object>();
for (int i = 1; i <= columnCount; i++) {
rowData.put(md.getColumnName(i), rs.getObject(i));
}
list.add(rowData);
}
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
if (rs != null)
rs.close();
rs = null;
} catch (SQLException e) {
e.printStackTrace();
}
}
return list;
}
public static Map<String, Object> convertMap(ResultSet rs){
Map<String, Object> map = new TreeMap<String, Object>();
try{
ResultSetMetaData md = rs.getMetaData();
int columnCount = md.getColumnCount();
while (rs.next()) {
for (int i = 1; i <= columnCount; i++) {
map.put(md.getColumnName(i), rs.getObject(i));
}
}
} catch (SQLException e){
e.printStackTrace();
} finally {
try {
if (rs != null)
rs.close();
rs = null;
} catch (SQLException e) {
e.printStackTrace();
}
return map;
}
