A list of "known" session attributes (listed in @SessionAttributes)
was gradually built as attributes get added to the model. In a
failover scenario that knowledge is lost causing session attributes
to be potentially re-initialized via @ModelAttribute methods.
With this change @SessionAttributes listed by name are immediately
added to he list of "known" session attributes thus this knowledge
is not lost after a failover. Attributes listed by type however
still must be discovered as they get added to the model.
The "default" FlashMapManager implementation added in 3.1 was invoked
after the redirect, which is too late in cases where the HTTP session
has not been yet been created since as the response is committed.
This change corrects the issue and makes other improvements to the
FlashMapManager implementation such as extracting a base
AbstractFlashMapManager class and making it easier for other
implementations to be added (for example cookie-based).
A direct path match with incorrect HTTP request method was causing another
request mapping with a pattern and a correct HTTP method to be ignored.
The bug affects the new @MVC support classes
(i.e. RequestMappingHandlerMapping).
The AbstractHttpMessageConverter was using the requested Content-Type
rather than the actual response Content-Type to determine the length
of the content. This can lead to a problem when a controller returns
a ResponseEntity with a Content-Type header that ignores (overrides)
the requested Content-Type. The fix ensures that actual response
Content-Type is the one used both to write to the response and to
determine the length of the content.
The UriComponentsBuilder instance passed into the method is initialized
with current request information including host, scheme, port, context
path, and the servlet mapping's literal part.
Also added shortcut methods to buildAndExpand in UriComponentsBuilder.
The Content-Type header and the contentType field in HttpServletRequest/Response
are now always in sync. When a header is added the contentType field is updated
as well and vice versa.
Similarly when the Content-Type header or the contentType field includes a charset
field, the character encoding is updated and vice versa.
Since dynamic attributes were allowed in Spring 3, it raised the
possibility to specify a type attribute on a number of the form tags.
Where it makes sense (see below) that attribute is now rejected
and reversely where it makes sense it is accepted.
InputTag allows types other than "text" but rejects type="radio" or
type="checkbox" since there is a good reason for those to be used
only in conjunction with the appropriate form library tags.
Other HTML input tags such as PasswordTag, HiddenInputTag,
Checkbox(es)Tag and RadioBox(es)Tag check the dynamic attributes
and reject them if they contain a type attribute since.
Certain external javadoc links were broken or out of date, namely
Hibernate, Java SE and EE 6, Quartz, and Apache Pluto. All resolve
properly now.
