回答1:

the view page code to view error and suces msg in different style

   <g:if test="${flash.message}">
        <div class="message" role="status" style="font-size: medium;color: green;">${flash.message}</div>
    </g:if>
    <g:if test="${flash.warning}">
        <div class="message_error" style="font-size: medium;color: red;">${flash.warning}</div>
    </g:if>

the controller code to call respective label if scues:

flash.message = message(code: 'Applied Successfully', args: [message(code: 'hrIrRegistration.label', default: 'HrIrRegistration'), hrIrAplcJobAppldLkInstance.id])
                redirect(controller: "hrIrRegistration", action: "showVcnyForApplcnt", id: params.hrIrVcncyIdHrIrVcncy.id)

if error:

flash.warning = message(code: 'You have already Applied in this vacancy', args: [message(code: 'hrIrRegistration.label', default: 'HrIrRegistration'), hrIrAplcJobAppldLkInstance.id])
                redirect(controller: "hrIrRegistration", action: "showVcnyForApplcnt", id: params.hrIrVcncyIdHrIrVcncy.id)
