的Tomcat無法啓動的Grails applocation

Question

這是我的控制器：

def delete(){ 
    def response = fileManageService.delete(params.a,params.b,params.c) 
    def SpaceVal = fileManageService.Space(params.d) 
    def message = ["message":response ,"data": SpaceVal] 
    render message as JSON 
} 

這是我的服務：

def Space(def d){ 
    try{ 
     File fileObj = new File(d) 
     def useSpace = fileObj.getSpace() 
     return useSpace 
    }catch(Exception e){ 
     return e.getMessage(); 
    } 
} 

將代碼添加到現有的工作程序後，Tomcat是無法編譯代碼並引發以下日誌錯誤。

誰能幫我弄清楚是什麼原因導致了這個錯誤？

Answer 1

您的日誌中有多個錯誤，但都歸結爲FileManageService不存在的事實。你沒有在這裏提供整個服務（你也不需要），但我的猜測是該文件中存在編譯錯誤，並且它沒有成功編譯。因此，它不包含在您的應用程序中，並且在您調用它時不存在。

使用你的IDE（如果你有一個，如果你沒有，有很好的免費可用的！看看Intellij！）來追蹤代碼中的錯誤。
