Question

这是我的控制者：

 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无法编译代码并引发以下日志错误。

任何人都可以帮我找出导致此错误的原因吗？

Answer 1

您的日志中有多个错误，但它们都归结为FileManageService不存在。你没有在这里提供整个服务（你真的不需要），但我的猜测是该文件中某处存在编译错误，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。

使用您的IDE（如果您有一个，如果没有，可以使用免费的IDE！请查看Intellij！）以跟踪代码中的错误。
