Why is Spring 3.2 only mapping my Boolean based on that the requestparam is "0" or "1" ?
@RequestParam(required= false, defaultValue = "false") Boolean preview Preview will only be "true" when the requestparam is "?preview=1" which is wierd
I want it to be "?preview=true". How do I do that?

You can also use the primitive boolean type for @RequestParam in place of Boolean . In this case, Spring automatically assigns false . For example, the following isCanceled param is optional. When you hit the URI http://localhost:8080/orderStatus , then the Spring assigns false to the isCanceled primitive.
Method parameters annotated with @RequestParam are required by default. This means that if the parameter isn't present in the request, we'll get an error: GET /api/foos HTTP/1.1 ----- 400 Bad Request Required String parameter 'id' is not present.
@RequestParam annotation enables spring to extract input data that may be passed as a query, form data, or any arbitrary custom data.
I think we may need more detail in order to be effective answering your question.
I have working Spring 3.2 code along the lines of:
@RequestMapping(value = "/foo/{id}", method = RequestMethod.GET) @ResponseBody public Foo getFoo( @PathVariable("id") String id, @RequestParam(value="bar", required = false, defaultValue = "true") boolean bar) { ... } Spring correctly interprets ?bar=true, ?bar=1, or ?bar=yes as being true, and ?bar=false, ?bar=0, or ?bar=no as being false.
True/false and yes/no values ignore case.

Spring should be able to interpret true, 1, yes and on as true boolean value... check StringToBooleanConverter.
