一次渲染多个对象

我正在尝试将多个对象呈现为 JSON。我的控制器代码如下所示：

 def showClient = {
    if (springSecurityService.isLoggedIn()) {
        def q_param = params.name_startsWith;
        def listOfClients =ClientRole.findAll("FROM ClientRole WHERE  party.name LIKE ? AND is_active =true",["%"+q_param+"%"])
        def point= Point.get(1)

        ArrayList<DisplayableName> clientList = ParameterFormatter.getFormattedDisplayNameList(listOfClients)
        def json = clientList as JSON
        log.debug("showClients :: jsondata = "+json)
        render json
    }else{
        redirect(controller:'login',action: "auth")
    }
}

这里我仅将 clientList 渲染为 json，但我还想渲染 point 对象。如何同时渲染 clientList 和 point 对象？

I am trying to render multiple objects as JSON. My controller code looks like:

 def showClient = {
    if (springSecurityService.isLoggedIn()) {
        def q_param = params.name_startsWith;
        def listOfClients =ClientRole.findAll("FROM ClientRole WHERE  party.name LIKE ? AND is_active =true",["%"+q_param+"%"])
        def point= Point.get(1)

        ArrayList<DisplayableName> clientList = ParameterFormatter.getFormattedDisplayNameList(listOfClients)
        def json = clientList as JSON
        log.debug("showClients :: jsondata = "+json)
        render json
    }else{
        redirect(controller:'login',action: "auth")
    }
}

Here I am rendering only clientList as json, but I also want to render the point object. How can I render both clientList and point object at the same time?

您可以尝试：

render(contentType: 'text/json') {
    delegate.clientList = clientList
    delegate.point = point
}

这将产生一个 JSON 对象，如下所示：

{
    "clientList": [ /* client list */ ],
    "point": { /* point object */ }
}

You can try:

render(contentType: 'text/json') {
    delegate.clientList = clientList
    delegate.point = point
}

This will result in a JSON object like:

{
    "clientList": [ /* client list */ ],
    "point": { /* point object */ }
}

在渲染为 JSON 之前，我总是将所有内容放入地图中！所以试试这个：

def showClient = {
    if (springSecurityService.isLoggedIn()) {
        def q_param = params.name_startsWith;
        def listOfClients =ClientRole.findAll("FROM ClientRole WHERE  party.name LIKE ? AND is_active =true",["%"+q_param+"%"])
        def point= Point.get(1)

        ArrayList<DisplayableName> clientList = ParameterFormatter.getFormattedDisplayNameList(listOfClients)
        def map = [clients:clientList]
        map << [point:point]
        def json = map as JSON
        render json


    }else{
        redirect(controller:'login',action: "auth")
    }
}

I always put everything in a map before rendering as JSON! so try this:

def showClient = {
    if (springSecurityService.isLoggedIn()) {
        def q_param = params.name_startsWith;
        def listOfClients =ClientRole.findAll("FROM ClientRole WHERE  party.name LIKE ? AND is_active =true",["%"+q_param+"%"])
        def point= Point.get(1)

        ArrayList<DisplayableName> clientList = ParameterFormatter.getFormattedDisplayNameList(listOfClients)
        def map = [clients:clientList]
        map << [point:point]
        def json = map as JSON
        render json


    }else{
        redirect(controller:'login',action: "auth")
    }
}
