In order to determine why classloading errors occur after
upgrading to 4.2.0.Final.
To demonstrate this error, uncomment the 4.2.0.Final dependency in
ivy.xml and run `ant test` within the .web.servlet module.
This method allows a view to access the combined context path and
servlet mapping path for prefixing URLs without having to specify
the literal part of a servlet mapping such as "/main/*")
explicitly everywhere. For example:
${requestContext.pathToServlet}/css/main.css
Currently the combine method consolidates "/*" and "/hotel"
into "/hotel". However if the first pattern contains URI template
variables, the consolidation seems wrong. The fix is to prevent
the consolidation if the first pattern contains "{".
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 initial solution kept these three in full sync at all times:
contentType field, characterEncoding field, 'Content-Type' header.
That is correct behavior, however it breaks existing tests that rely
on contentType and characterEncoding being equal to exactly what
they were set to.
For example, consider:
response.setContentType("text/plain");
response.setCharacterEncoding("UTF-8");
Ideally both contentType and the 'Content-Type' header would now be
"text/plain;charset=UTF-8". However, existing tests would expect
that contentType is equal to "text/plain".
To avoid breaking existing tests, contentType and characterEncoding
will continue to be equal to exactly what they were set to while
the 'Content-Type' header will always include both the content
type and the charset.
The only exception to this rule is when a 'Content-Type' header
is set explicitly, the contentType and characterEncoding fields will
be updated accordingly, possibly overriding the existing values.
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.
Use of package private @Bean methods can cause issues if the class
is extended and the sub-class is in a different package. This is
covered in detail in SPR-8756.
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.
