How to Change Controller Name and function name URL in Grails 2.2.2?

Question

I am trying to change my controller name and method name in grails

e.g :abc.com/newUser/viewUser/4

i want to convert in below format e.g :abc.com/new-user/view-user/4

Or

e.g :abc.com/new_user/view_user/4

for that i wrote a code :

package customize

import grails.web.UrlConverter

import org.apache.commons.lang.StringUtils

class CustomUrlConverter implements UrlConverter {

    private static final String GRAILS_EXTENSION = '_'

    String toUrlElement(String propertyOrClassName) {

        if (StringUtils.isBlank(propertyOrClassName)) {

            return propertyOrClassName

        } else {

            String[] r =    propertyOrClassName.split("(?=\\p{Upper})");
            String lowerPropertyOrClassName = propertyOrClassName.toLowerCase();
            println r.length + "size()";
            String extendedPropertyOrClassName="";
            if(r.length > 1){
                for(int i=0; i < r.length;i++){
                    extendedPropertyOrClassName = extendedPropertyOrClassName + r[i].toLowerCase()
                    if(i+1 <  r.length ){
                    extendedPropertyOrClassName =addGrailsExtension(extendedPropertyOrClassName);
                    }
                }
            }else{
                extendedPropertyOrClassName =  propertyOrClassName.toLowerCase()
            }
            return extendedPropertyOrClassName

        }
    }



    private String addGrailsExtension(String propertyOrClassName) {

        if (propertyOrClassName.endsWith(GRAILS_EXTENSION)) {

            return propertyOrClassName

        } else {

            return propertyOrClassName + GRAILS_EXTENSION

        }

    }
}

In Config.groovy

grails.web.url.converter = 'hyphenated'

// grails-app/conf/spring/resources.groovy

beans = {
    "${grails.web.UrlConverter.BEAN_NAME}"(com.myapplication.MyUrlConverterImpl)
}

In this when i am trying to get all character in small letter like below Url

e.g :abc.com/newuser/viewuser/4

its working fine

But when i add underscore in between two character like below Url

e.g :abc.com/new_user/view_user/4

Its gives an error 404.. Please Help me out. If you have any other option to change URL also welcome..

Thank you

One of the easiest way to achieve your requirement is UrlMappings.groovy

"/new_user/view_user/$id"(controller: 'newUser', action: 'viewUser')
