Spring 3.0 annotated formatting: style/pattern not applied

[dxxvi]

Maybe everybody knew it already, so this message is for myself only: Joda time is needed if @DateTimeFormat is used or we'll see sth like:

20:15:10 DEBUG AbstractHandlerExceptionResolver:132 - Resolving exception from handler [home.OneController@1f5cbd6]: org.springframework.beans.TypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'java.util.Date'; nested exception is org.springframework.core.convert.ConversionFailedException: Unable to convert value "30-041982" from type 'java.lang.String' to type 'java.util.Date'; nested exception is java.lang.IllegalStateException: JodaTime library not available - @DateTimeFormat not supported

20:15:10 DEBUG DispatcherServlet:824 - Null ModelAndView returned to DispatcherServlet with name 'test': assuming HandlerAdapter completed request handling

The spring-mvc-showcase on github also says that.

I've read that @DateTimeFormat is avaiable in Spring MVC, but I'm working with Spring Portlets. Is it avaiable for this case too? How I have to proceed? must I include <mvc:annotation-driven/> in my applicattion-context.xml file too?

Now I'm printting my @DateTimeFormat date in a JSP without obtaining the expected result:


@DateTimeFormat(pattern="dd-MM-yyyy")
private java.util.Date myDate;

and that's what I have printed: 2011-12-30 10:06:18.0 as result of <c:out value="${myForm.myDate}"></c:out>

I've tried also with @DateTimeFormat(style="S-"), including and excluding the <mvc:annotation-driven/> and obtaining the same result, some help?

In Spring 3.1 @NumberFormatter does not allow pattern to be used for Currency or Percent types so the fractionDigits is a needed and missing annotation field. Furthermore rounding is always ROUND_HALF_EVEN (the default for BigDecimal) meaning rounding is a needed and missing annotation field. Another useful missing property is multiplier. That is the reason I had to come up with a CustomNumberFormatter and bunch of classes that I have documented at http://thinkinginsoftware.blogspot.c...on-driven.html, hopefully it will be useful as a tutorial to get custom Converters working in Spring.
