Method Detail

initBinder

public void initBinder(WebDataBinder binder,
                       NativeWebRequest request)
                throws java.lang.Exception

Initialize a WebDataBinder with @InitBinder methods. If the @InitBinder annotation specifies attributes names, it is invoked only if the names include the target object name.

Overrides:

initBinder in class DefaultDataBinderFactory

Parameters:

binder - the data binder instance to customize

request - the current request

Throws:

java.lang.Exception - if one of the invoked @InitBinder methods fail.

isBinderMethodApplicable

protected boolean isBinderMethodApplicable(HandlerMethod initBinderMethod,
                                           WebDataBinder binder)

Return true if the given @InitBinder method should be invoked to initialize the given WebDataBinder.

The default implementation checks if target object name is included in the attribute names specified in the @InitBinder annotation.
