When a @ModelAttribute is instantiated from a URI variable with type
conversion, if conversion fails allow the exception to propagate.
This is consistent with what happens on type conversion failure with
@PathVariable and other args that rely on type conversion.
Make it possible to hook in custom ServletRequestDataBinderFactory
by overriding RequestMappingHandlerAdapter.
Create ExtendedServletRequestDataBinder to add URI template vars
to the binding values taking advantage of a new extension hook in
ServletRequestDataBinder to provide additional values to bind.
RequestCondition types keep individual expression types (e.g. the
discrete header or param expressions) package private. Although the
implementation of these types should remain private, there is no
reason not to provide access to the underlying expression data --
e.g. for creating a REST endpoint documentation tool, or if you
want to know which of the "consumes"/"produces" media types
are negated.
This change ensures that all RequestCondition types have a public
getter that makes available the basic expression data.
1. Consider single-purpose return value types like HttpEntity, Model,
View, and ModelAndView ahead of annotations like @ResponseBody and
@ModelAttribute. And reversely consider multi-purpose return value
types like Map, String, and void only after annotations like
@RB and @MA.
2. Order custom argument resolvers and return value handlers after the
built-in ones also clarifying the fact they cannot be used to override
the built-in ones in Javadoc throughout.
3. Provide hooks in RequestMappingHandlerAdapter that subclasses can use
to programmatically modify the list of argument resolvers and return
value handlers, also adding new getters so subclasses can get access
to what they need for the override.
4. Make SessionStatus available through ModelAndViewContainer and
provide an argument resolver for it.
5. Init test and javadoc improvements.
Previously, #containsBean Javadoc advertised that a true return value
indicates that a call to #getBean for the same name would succeed.
This is actually not the case, and has never been. The semantics
of #containsBean have always been to indicate whether a bean definition
with the given name is definied or a singleton instance with the given
name has been registered.
The Javadoc now reflects this accurately.
Issue: SPR-8690
Cite original inspiriation by Domain-Driven Design, but make clear the
flexible and general-purpose nature of Spring's stereotype annotations
such as @Repository and @Service.
Also update @Repository Javadoc with more explicit instructions about
switching on exception translation through use of
PersistenceExceptionTranslationPostProcessor, and update PETPP Javadoc
for style as well as concrete examples of 'resource factories' that
implement the PersistenceExceptionTranslator interface
