Spring MVC populate @RequestParam Map

Question

I have the following method in my Spring MVC @Controller :

@RequestMapping(method = RequestMethod.GET)
public String testUrl(@RequestParam(value=\"test\") Ma         


        

Answer 1

As detailed here https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/bind/annotation/RequestParam.html

If the method parameter is Map or MultiValueMap and a parameter name is not specified, then the map parameter is populated with all request parameter names and values.

So you would change your definition like this.

@RequestMapping(method = RequestMethod.GET)
public String testUrl(@RequestParam Map parameters) 
{   
  (...)
}

And in your parameters if you called the url http://myUrl?A=ABC&B=DEF

You would have in your method

parameters.get("A");
parameters.get("B");
