grails - 用于休息和其他操作的Grails UrlMappings

Question

我有一个 Controller ，该 Controller 主要用于使用show，update，save和delete操作的REST通信。相应地将其映射到UrlMappings.groovy文件中，并且工作正常。

然后，我需要在同一 Controller 中调用getAccountTypesByEnv Action ，但是我在设置实际上有效的语法时遇到了一些麻烦。

下面的定义有效，但是我想知道是否存在更简单，更正确的方法。

"/ext/accounttype/$id?"(controller: "accountType") {
    action = [GET: 'show', PUT: 'update', POST: 'save', DELETE: 'delete']
    "/ext/accounttype/getAccountTypesByEnv"(controller: "accountType", action: "getAccountTypesByEnv")
}

更新

我最终将其分为两个单独的通用映射，如下所示:

"/ext/$controller/$id?" {
     action = [GET: 'show', PUT: 'update', POST: 'save', DELETE: 'delete']
}

"/ext/$controller/action/$customAction?" {
     action = { return params.customAction }
}

Answer 1

您可以像这样在UrlMappings.groovy中定义:

 "/ext/$controller/$resourceId?/$customAction?" {
    action = {
        Map actionMethodMap = [GET: params.resourceId ? "show" : "index", POST: "save", PUT: "update", DELETE: "delete"]

        return params.customAction ?: actionMethodMap[request.method.toUpperCase()]
    }
    id = {
        if (params.resourceId == "action") {
            return params.id
        }
        return params.resourceId
    }
}

这是我目前认为最通用的 UrlMapping，您可以通过以下方式在此处使用它:

GET     "/ext/accounttype" will call **index** action of AccounttypeController
POST    "/ext/accounttype" will call save action of AccounttypeController
PUT     "/ext/accounttype/14" will call update action of AccounttypeController with id 14
DELETE  "/ext/accounttype/14" will call update action of AccounttypeController with id 14
GET     "/ext/accounttype/14" will call show action of AccounttypeController with id 14
GET     "/ext/accounttype/action/getAccountTypesByEnv" will call getAccountTypesByEnv action of AccounttypeController with null id
GET     "/ext/accounttype/action/getAccountTypesByEnv?id=143" will call getAccountTypesByEnv action of AccounttypeController with id 143
