Answer 1

DataController类：

class DataController {

    static allowedMethods = [save: "POST", update: "POST", delete: "POST"]

    def doSomeThing() {
        def myData = dataService.dataMethod(params)
        render(view: "show", model:[myData:myData])
    }
............
}

show.gsp：

...........
<!-- show response data -->
${myData}
<!-- thats it -->
