Java Tomcat无法启动grails应用程序定位

这是我的控制器：

 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
 }

这是我的服务：

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

将代码添加到现有工作应用程序后，tomcat无法编译代码，并抛出以下日志错误

有人能帮我找出导致此错误的原因吗？

您的日志中有多个错误，但都是由于FileManageService不存在。您没有在这里提供整个服务（您也不需要），但我猜该文件中的某个地方存在编译错误，并且没有成功编译。因此，它不包含在您的应用程序中，并且在您调用它时不存在

使用你的IDE（如果你有，如果你没有，还有很好的免费IDE！看看Intellij！）来跟踪代码中的错误。

此外，按照惯例，方法的名称不能用大写字母开头。这使它看起来像一个内部类，并且确实使调试更加困难！在添加代码段之前，应用程序工作得很好，当我删除服务方法并部署时，它再次成功编译。您的文件对象是什么？我在java.io.File上没有看到getSpace（）方法，也没有看到Groovy对它的增强。
