rest - 在UrlMappings中定义的REST资源产生404

使用grails 3.0.9，我定义了2个域:

Game -> hasMany plays
Play -> belongsTo game

我已经将以下内容添加到我的UrlMappings.groovy文件中。

"/games"(resources: "game") {
  "/plays"(resources: "play")
}

使用Postman，我正在获得http://localhost:8080/games，并且得到了404。

如果删除UrlMappings并将@Resource(uri='/games')放在Game域上，则它会返回200，这与预期的一样。这是我运行url-mappings-report时得到的:

 |   GET    | /games/${gameId}/plays                            | Action: index            |
 |  DELETE  | /games/${gameId}/plays/${id}                      | Action: delete           |
 |  PATCH   | /games/${gameId}/plays/${id}                      | Action: patch            |
 |   PUT    | /games/${gameId}/plays/${id}                      | Action: update           |
 |   GET    | /games/${gameId}/plays/${id}                      | Action: show             |

不知道为什么UrlMappings不起作用。

最佳答案

我的理解是UrlMappings语法"/games"(resources: "game")自动生成关联的RESTful映射(并且仅生成映射)，而使用@Resource(uri='/games')语法生成 Controller / Action 。

使用"/games"(resources: "game")，您仍然需要定义自己的 Controller 。您写这个问题的方式，让我觉得您还没有这样做。
