Custom DataBinder Hook [SPR-6534]

[spring-projects-issues]

Pavel Müller opened SPR-6534 and commented

I'm migrating our project to Spring 3.0. Most of the issues is resolved but one of them not.

We used to create our own custom DataBinder in a AnnotationMethodHandlerAdapter subclass. We used to override the createBinder() method and created our own DataBinder implementation there.

How to achieve the same in Spring 3.0. The createBinder() method disappeared.

I think this issue hurts backwards compatibility too. Our project has a lot of following methods:
@InitBinder
public void initBinder(MyDataBinder binder) {
...define custom editors here.
}

We use custom data binder to specify empty values for bound fields as well as allowed fields and other things.

I'd prefer this issue to be resolved in 3.0 GA rather then later. For us it's a blocker to migrate to Spring 3.0

I've reintroduced the createBinder template method in AnnotationMethodHandlerAdapter. Overriding createBinder should work again now, even in binary compatible form (e.g. with precompiled Spring 2.5 extensions).

This will be available in the next snapshot. I'll post the URL once it is available.
