Have ConversionFailedException store/expose the failed value [SPR-6629]

[spring-projects-issues]

Chris Hubick opened SPR-6629 and commented

The org.springframework.core.convert.ConversionFailedException constructor currently accepts an "Object value - the value we tried to convert" argument, which it uses while constructing the exception detail message, but it doesn't store this value, nor provide a getValue() accessor method.

For client code dealing with the conversion of more complex custom classes, the ability to catch a ConversionFailedException and gain a reference to the failed value would enable that code to use it to provide much better logging/error/debugging context information than a simple toString() of the failed value will currently provide.

Thanks for you consideration.

Good point! I've added a "getValue()" method that exposes the actual value object.
