[Springframework-developer] HTML escaping and other changes to the web package

[<jue...@we...>]

Hi everybody,

I've just finished the HTML escaping support and some minor tweaks of =
the web package:

- Reworked tags: Spring's custom tags have an optional boolean =
"htmlEscape" property now, and there's a new htmlEscape tag for setting =
a default value. For escaped Errors as returned by the hasBindErrors =
tag, an Errors proxy is used, adding HTML escaping for affected methods. =


- RequestContextUtils: JSP expressions can use simple utility methods in =
RequestContextUtils for retrieving either escaped or plain versions of =
Errors and messages, and the current Locale. ControllerServlet exposes a =
locale attribute to the request now, analogous to the =
WebApplicationContext. I've dissolved =
com.interface21.web.bind.BindUtils, as its functionality is now covered =
by RequestContextUtils.

- RequestContext: An alternative approach, also suitable for Velocity =
and JSTL, is using the new RequestContext and reading its properties. A =
RequestContext instance can automatically get added as a request =
attribute with a specified name (for convenient access) via =
AbstractViews's new "requestContextAttribute" property.

- Startup simplification: FrameworkServlet and thus ControllerServlet =
implictly call ContextLoader now if no WebApplicationContext has been =
initialized previously. This means that explictly declaring =
ContextLoaderListener or ContextLoaderServlet in web.xml is entirely =
optional now, at least if you do have one or more ControllerServlet =
declarations with load-on-startup!

- Context refresh: ApplicationContext has a new ContextRefreshedEvent =
that gets published after initializing all beans. This allows for =
implementing a respective listener bean that performs some startup work =
using other beans, therefore needing all beans preinitialized instead of =
just itself. An example is a custom configurer that reads some =
administration config file outside of the application context and =
populates respective properties of various beans.

- Locale resolution: Correct locale attribute usage in all view =
implementations.

- Validation: Slightly polished API.

Looking forward to your feedback!

BTW, there's only one of my proposals left now: multipart request =
handling. I will try to start work on it next week - expect a finished =
initial solution the week after.

Regards,
Juergen
