grails groovyPageRenderer injecting in file inside src/groovy

I want to inject groovyPageRenderer in a src/groovy/GSPFormatter, How can I do that without calling the new constructor?

EDIT

package gsprenderer
import spud.core.FormatterInterface
import grails.gsp.PageRenderer

class GSPFormatter implements FormatterInterface {

   PageRenderer groovyPageRenderer = grailsApplication.mainContext.getBean('groovyPageRenderer')

   String compile(String content) {
      groovyPageRenderer.render(view: new ByteArrayOutputStream().write(content.bytes), null)
   }
}

is my code in src/groovy/GSPFormatter (basically with the default injection mechanism which doesn't work either)

Solution

I think, you are referring to grails.gsp.PageRenderer ... btw, I am using Grails 3.3.0

Here is a small (tested) example -

In application.yml

grails:
    spring:
        bean:
            packages:
                    - ovr

in scr/groovy/ovr

package ovr.renderer

import grails.gsp.PageRenderer
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.stereotype.Component

@Component
class CustomRenderer {
    @Autowired
    PageRenderer pageRenderer

    def page(){
        pageRenderer.render(view: '/myrenderer', model: [hello: 'hello'])
    }

}

in controller

@Autowired
CustomRenderer customRenderer

def myPage(){
    render customRenderer.page()
}

in views/myrenderer.gsp

${hello}
