hecking is an interesting idea - I'm just not sure that
it makes it much less error prone - in both cases, you need to type

It's not my idea, actually. I found it in the section "JavaBean and Map

It's not my idea, actually. I found it in the section "JavaBean and Map
parameters" of "iBatis in Action". It sais:
"If you create a parameter map with a bean and attempt to refer to a

I dont know how iBatis set the properties of a bean. In case it uses
reflection, it surely will slower than hashmap. But if it uses the
bean.set...(...) directly, i believe it is faster than hashmap.

I don't know about the performance - a hashmap is pretty fast for
retrieval. (FYI: the constructor you use there will cause slower
performance - the default would use more memory, but be faster - using
3 or 4 as the parameter might be better, read the javadocs on that
one.)
The parameter checking
Thanks, Larry!
but could you tell me why? I thought using an anonymous class has an
important advantage: it allows loading-time parameter check. Also I
think it should be faster than using HashMap. Isn't it true?

Hello all,
what should I prefer, this:
return getSqlMapClientTemplate().queryForList("listEvaluationPlans", new
Object() {
long getPersonId() { return personId; }
String getLang() { return lang; }
});
or this:
final Map params = new HashMap(2);
params.put("personId", personId);
params
