Can ibatis work with java object with constructor have parameters?
I like to pass something to the object while initalization, can I
specific about that?

Bah, gmail messed up my code...let's try again...
===
Reader reader;
SqlMapClientImpl smc;
SelectStatement statement;
String sql;
// this is just plumbing:
reader = Resources.getResourceAsReader("com/mwt/config/sqlmap.xml");
smc = (SqlMapClientImpl) SqlMapClientBuilder.buildSqlMapClient(reader);
// At this point, you can get a statement and get freaky with it
// ...all unsupported of course, and if a later release breaks it, you
// have been warned. :-)
statement = (SelectStatement)
smc.getDelegate().getMappedStatement("Customers.fetch");
// replace the 2nd parameter below with YOUR parameter object, a
// bean or map or whatever.
sql = statement.getSql().getSql(null, null);
// ALSO, who says this has to be SQL? it could be HQL, or an LDAP query, or

Hey Paul,
If all you want is the SQL, you can get that with a tiny bit of hacking:
===
Reader reader;
SqlMapClientImpl smc;
SelectStatement statement;
String sql;
// this is just plumbing:
reader = Resources.getResourceAsReader("com/mwt/config/sqlmap.xml");
smc = (SqlMapClientImpl) SqlMapClientBuilder.buildSqlMapClient(reader);
// At this point, you can get a statement and get freaky with it
// ...all unsupported of course, and if a later release breaks it, you
// have been warned. :-)
statement = (SelectStatement)
smc.getDelegate().getMappedStatement("Customers.fetch");
// replace the 2nd parameter below with YOUR parameter object, a
bean or map or whatever.
sql = statement.getSql().getSql(null, null);
// ALSO, who says this has to be SQL? it could be HQL, or an LDAP query, or
// whatever other crazy stuff you want to try. This is the result
in any case:
System.out.println(sql);

Jumping in a little late here but I do exactly this, and I use iBATIS
*and* I don't require any new iBATIS features. It's pretty simple:
- Turn off iBATIS caching
- Build a Factory layer that sites right about your iBATIS layer
- Use something like ehcache, oscache, etc. in your factories along
with some simple methods to ensure object identity

@key is nice and key is probably what I only need also.

Posted by Paul Benedict <pb...@apache.org>.
Brandon,
I am happy with your response. Yes, I am trying to address a current
failure in extensibility. I could do something with the RowHandler,
except it's the wrong point in the lifecycle of the data mapper. A
RowHandler gives you back an object -- but this is not ideal since I
need to first determine if I have the object already. So in theory I am
wasting memory and time to create objects I most likely will be tossing
away.
You could add to IBATIS this way:
* Allow me to attach a cache at the resultMap level.
* Add a @key attribute to a resultMap. This would flag one or multiple
properties as being a primary key, and then ibatis could then, if a
cache is present, check if an object already exists.
<resultMap id="roleMap" cacheModel="roleObjectCache">
...
</resultMap>
* Add some other feature to allow flushing of a single object from the
object cache.

I already do this :-) I front my DAOs with a layer and use OSCache.
However, this can get very tedious and tough to manage as the # of my
DAOs grow. If this kind of caching at the object level can be built
straight into ibatis, life would be easier.

I think there are better ways to address these sorts of issues and remain
true to what iBATIS is about. What you are pointing out would be more tied
to a potential failure in iBATIS extensibility than about getting access to
a raw ResultSet. Also, the caching sounds like something you can implement
with a RowHandler.

Re: Can ibatis work with java object with constructor have parameters?
Posted by Paul Benedict <pb...@apache.org>.
Brandon,
Sometimes it's good to construct the object directly with access to the
ResultSet, but using IBATIS to dynamically write the SQL. There's a
ticket open for this functionality:
http://issues.apache.org/jira/browse/IBATIS-226
My driver is because I cache at the object instance level, and return
the same instance for the same primary key. This is a little deeper than
ibatis' caching which is at the statement level -- but with multiple
statements potentially returning the same object (in terms of object
identity), this is where having access to the ResultSet is necessary. If
I can shortcut the creation of the object, I will.

Re: Can ibatis work with java object with constructor have parameters?
Posted by Carfield Yim <ca...@gmail.com>.
That is kind of surprise me, I thought this is a common use case to
implement role permission. However look like this is not the case.
In fact I just do it this way in my last application as we write DAO
ourselves without any tools. May be you can share how ibatis user
commonly do for role permission?

Re: Can ibatis work with java object with constructor have parameters?
Posted by Clinton Begin <cl...@gmail.com>.
ACK!!! Sorry, my bad. It wasn't RowHandler. It was the custom
TypeHandlerCallback. ResultGetter now exposes the ResultSet.
Sorry for the confusion and my unclear brain before my Starbucks Grande
Half-Sweet Vanilla Americano with room.

Hi,
I would like to ask you if iBatis offers support for the following JDBC
function:

Re: Can ibatis work with java object with constructor have parameters?
Posted by Larry Meadors <lm...@apache.org>.
Hmm, RowHandler is clear of java.sql references - as it should be.
There are some ResultSet references passed around in the type handler
extension points..

Re: Can ibatis work with java object with constructor have parameters?
Posted by Brandon Goodin <br...@gmail.com>.
Do you mean the TypeHandlerCallback which has a method called
getResult(ResultGetter). From the ResultGetter.getResultSet() you could get
the ResultSet. But, again this seems like a HUGE hack to accomplsh what is
desired.

Re: Can ibatis work with java object with constructor have parameters?
Posted by Clinton Begin <cl...@gmail.com>.
Except for that new method Larry added to the RowHandler APIs...you can now
get the original ResultSet while the rows are being returned from within a
RowHandler.
But other than that very isolated case, Brandon is right, you can't just
arbitrarily get the ResultSet and do with it as you please.
Cheers,
Clinton

Posted by Brandon Goodin <br...@gmail.com>.
No you cannot get a ResultSet. iBATIS will not at anytime from anywhere
provide you a reference to the ResultSet.

Re: Can ibatis work with java object with constructor have parameters?
Posted by Carfield Yim <ca...@gmail.com>.
Just really read
http://ibatis.apache.org/docs/java/dev/com/ibatis/sqlmap/client/event/RowHandler.html
, However can I get the resultset from the RowHandler?

Sounds like you can use a RowHandler for this.

Re: Can ibatis work with java object with constructor have parameters?
Posted by Larry Meadors <lm...@apache.org>.
You would use iBATIS - it's using your SQL, no?
If it is using your SQL, in your SELECT statement, you can exclude
records based on anything in the result set using a WHERE or HAVING
clause.
Larry
PS: iBATIS is not an ORM tool, it's a data mapper. ;-)

It seems like this would be way more efficient to do in the SQL.
That way you don't have any overhead (i.e., network latency, object
creation, etc..).

Re: Can ibatis work with java object with constructor have parameters?
Posted by Carfield Yim <ca...@gmail.com>.
Actually I get I cannot do... but anyway, just ask.
For method http://ibatis.apache.org/docs/java/dev/com/ibatis/sqlmap/engine/mapping/result/ResultObjectFactory.html#createInstance(java.lang.String,
java.lang.Class)
instead of having
public Object ResultObjectFactory(String id, Class clazz) {
Constructor con = clazz.getDeclaredConstructor(new Class[]{String.class});
return con.newInstance(objectStaticAvailable);
}
Can I init the object using resultset result, like
public Object ResultObjectFactory(String id, ResultSet rs, Class clazz) {
Constructor con = clazz.getDeclaredConstructor(new Class[]{String.class});
return con.newInstance(rs.getString("id"));
}
So that I can use the ID of the record to check for permission when
initalization. If the user don't have permission to load that record,
the system will throw an exception and we will show an generic
permission deny page.

Re: Can ibatis work with java object with constructor have parameters?
Posted by Brandon Goodin <br...@gmail.com>.
I'm not completely sure what you are asking. But, if you are asking if you
can get the ResultSet itself that would be a no. iBATIS is JDBC wrapper. If
you find that you need more direct access to JDBC then you should use JDBC
directly.

Re: Can ibatis work with java object with constructor have parameters?
Posted by Carfield Yim <ca...@gmail.com>.
Can I get the reference of resultset when the object is initalizating?

You can find the javadoc here:
http://ibatis.apache.org/docs/java/dev/com/ibatis/sqlmap/engine/mapping/result/ResultObjectFactory.html
I was assuming you were wanting to map result values to a constructor. If
you are trying to map results to a constructor, it would seem a tedious
effort to use the ResultObjectFactory for this.
I know it is lame that we don't have this functionality. But, we've
discussed adding the constructor mapping functionality and have decided it
is best to delay adding it until iB3 (no eta).

I just check for the document and I cannot see those APIs ,
http://ibatis.apache.org/docs/java/user/ , am I looking for wrong
thing?

Have you considered using an implementation of ResultObjectFactory? It can be configured within iBatis or injected into the SqlMapExecutorDelegate. Either ways you will have control over the creation and subsequent initialization of objects.

You can do this using Spring. I think iBatis does not have to support this.
