使用Groovy的Spring MVC控制器

我正在設置一個webapp，我試圖用Groovy代替Java。我有基本的設置，webapp啓動。到目前爲止，我有一個具有適當註釋的Controller。在啓動過程中，RequestMappings被映射，但是當我嘗試訪問映射時，webapp使用404來回答。使用Groovy的Spring MVC控制器

我見過this post，但它沒有解決我的問題（既不使用接口也不使用PostProcessor）。

下面是從應用程序啓動的日誌，我看不到任何東西，看起來很奇怪：

這是控制器：

@Controller 
@RequestMapping("/mapping") 
class QueryController { 

    @RequestMapping("/show") 
    def show() { 
     return "show"; 
    } 
}

我缺少的東西，或做錯了什麼？幫助是非常appriciated！

如果你從頭開始，爲什麼不使用Grails？這正是基於春季Groovy的網絡應用程序。 – vector

根據日誌，你有一個名爲'QueryController'的控制器，其中一個映射到'/ query/show'的方法是'showQueryForm'。這個映射是否工作？這是一個Java控制器嗎？ – ataylor

@ataylor：控制器被命名爲QueryController，我更新了問題。該映射不起作用。 –

見鬼，檢查了這一點，第2點下來：使用Groovy 2

配置和實現Spring的風格的應用程序：基於Groovy的bean定義; Groovy中作爲首選從NEXT STOP: SPRING FRAMEWORK 4.0

的語言對整個應用

所以，你可能只是點點超前的時間在這裏:-)。但是你可能已經知道了。
