There is often a need to have the same @RequestParam in multiple methods and even in multiple controllers, e.g. a required filter param that is processed in a hibernate filter for security checking. To avoid repeating the same parameter in every request the only thing needed is to register a new @ControllerAdvice bean.

To show with an example:

import org.springframework.web.bind.annotation.ControllerAdvice
import org.springframework.web.bind.annotation.ModelAttribute
import org.springframework.web.bind.annotation.RequestParam

@ControllerAdvice("my.package.with.controllers")
class RequiredParameterControllerAdvice {

    @ModelAttribute
    public void requiredParam(@RequestParam Long requiredLongParameter) {
        // empty on purpose - @RequestParam is by default required so this
        // will throw validation error on request without requiredLongParameter
    }
}

The key things in this example are:

• @ControllerAdvice("my.package.with.controllers") which tells spring to apply this @ControllerAdvice only to controllers in listed packages (You could of course omit this so that this advice is applied for every controller).
• @ModelAttribute that binds requiredParam method parameter as a named model attribute
• And of course @RequestParam (which is required by default) that defines our parameter
