RE: [Springframework-developer] MappingSqlQuery - setTypes in app lication context?

[Kopylenko, D. <dko...@ac...>]

Darren,

AbstractBeanFactory.managedListToArray() tries to convert a List into
Object[]. I would guess, since "types" property is int[], that's where it's
getting ClassCastException. Am I correct? Anyone?

Regards,
Dmitriy.

Subject: [Springframework-developer] MappingSqlQuery - setTypes in
application context?


hi,

is it possible to declare a bean in an application context whose class is a
subclass of MappingSqlQuery and declare bind params?  Something like this:

<bean
    id="myMapper"
    class="some.subclass.of.MappingSqlQuery">
    <property name="sql"><value>SELECT * FROM table WHERE field=?
</value></property>
    <!-- 12 is the typecode for VARCHAR and somehow needs to be handled as
an int[] -->
    <property name="types"><list><value>12</value></list></property>
    <property name="dataSource"><ref bean="myDS"/></property> </bean>

I seem to be having a lot of troube getting the beans instantiated due to
the 'types' property, with the following trace:
java.lang.ClassCastException: java.lang.Object

Am I going about this the wrong way completely?

Cheers,
Darren.
