How to prevent parameter binding from interpreting commas in Spring 3.0.5?

Question

Consider the following controller method:

@RequestMapping(value = \"/test\", method = RequestMethod.GET)
public void test(@RequestParam(value = \"fq\", requi         


        

Answer 1

I have found the most elegant and the shortest way for me - add @InitBinder to a @Controller:

@InitBinder
public void initBinder(WebDataBinder binder) {
    binder.registerCustomEditor(String[].class, new StringArrayPropertyEditor(null));
}

It will convert String to String[] without using separator (null param), with Spring class org.springframework.beans.propertyeditors.StringArrayPropertyEditor. If someone in same project will use new default conversion way, it will be ok.
