Db.find(strSql, param)应该怎么用

String strSql = " select * from menu where id=? ";

List<Object> param = new ArrayList<Object>();

// param.add("d39a10ed-9089-0ff5-e302-9cdcb8ca3788");

param.add(new String("d39a10ed-9089-0ff5-e302-9cdcb8ca3788"));

List<Record> ls = Db.find(strSql, param);

for (int i = 0; i < ls.size(); i++) {

System.out.println(ls.get(i));

}

renderJson(ls);

List ls = Db.find(strSql,s.toArray()); list可以直接转数组，find不能传list的

写错了，是List ls = Db.find(strSql,para.toArray());

Db.find("select * from girls where age >? and weight < ?", 18, 50);
