Question

我的url映射配置如下：

class UrlMappings {

static mappings = {

    "/"(controller:"index")
    "/$controller/$action?/$id?(.${format})?"{
        constraints {
            // apply constraints here
        }
    }
    "500"(view:'/error')
    ////////////////////////

    "/recetas"(resources:"receta",version:'1.0',namespace:'user'){
        "/eventos"(resources:'evento',version:"1.0",namespace:"user")
    }

}

}

此网址映射会生成此网址映射报告。

我的EventoController

package com.ar.dasding

import grails.converters.JSON;
import grails.plugin.springsecurity.annotation.Secured;
import grails.transaction.Transactional;

@Transactional(readOnly = true)
@Secured(["ROLE_ADMIN"])
class EventoController {

def index(Integer max) {

    params.max = Math.min(max ?: 10, 100)

    def receta = Receta.get(params.recetaID)

    log.debug("Eventos para receta " + params.recetaID + ": " + receta.eventos)

    render receta.eventos as JSON
}

}

recetaController工作正常，但向EventoController发出此请求返回404

问题是控制器是否可能没有实现映射到url映射中的所有操作？

提前致谢。

Answer 1

我感觉网址映射的特殊性有些奇怪。

如果用以下内容替换“/ eventos”映射会发生什么：

“/ recetas / $ {recetaID} / EVENTOS”（控制器： “EVENTOS”，动作： “索引”）

本身，在'recetas'映射关闭之外

Grails控制器应该实现所有urlmappings？
