为什么我得到“不能被解析为类型“错误？ [英] Why I got " cannot be resolved to a type" error?

问题描述

我正在 Eclipse IDE下开发一个动态Web项目（RESTful jersey）。

在 src / my / demo / service 文件夹我有 CarService.java 类

  public class CarService {
 ... 
} 
  

在 src下/ my / demo / controller 文件夹我有 UserController.java 类

 导入我的.demo.service.CarService; 
 
 public class UserController {
 private CarService carService; //错误：CarServcie无法解析为类型
 
} 
  

我确实导入了 CarService ，为什么eclipse会在我的 UserController.java ？中给出错误 CarServcie无法解析为类型？ p>

--------编辑------------------

我发现原因：由于某种原因，在eclise项目资源管理器视图中， my.demo.service 具有与 src / 相同的级别。在我移动 my.demo.service src / 之前，没关系。看来我不应该在Eclipse的项目资源管理器视图中创建新的包...

但是谢谢你的回复：）

解决方案

你只需要去项目---> clean
请参阅http://philip.yurchuk.com/2008/12/03/eclipse-cannot-be-resolved-to-a-type -error /

I am developing a dynamic web project (RESTful jersey) under Eclipse IDE.

Under src/my/demo/service folder I have CarService.java class

public class CarService {
  ...
}

Under src/my/demo/controller folder I have UserController.java class

import my.demo.service.CarService;

public class UserController{
    private CarService carService; //ERROR: CarServcie cannot be resolved to a type

}

I do have imported the CarService, why eclipse give me the error "CarServcie cannot be resolved to a type" in my UserController.java?

--------Edit------------------

I found the cause: for some reason, my.demo.service has the same level as src/ in eclise project explorer view. After I move my.demo.service under src/, it is fine. Seems I should not create new package in "Project Explorer" view in Eclipse...

But thank you for your response:)

解决方案

u just need go to Project ---> clean See http://philip.yurchuk.com/2008/12/03/eclipse-cannot-be-resolved-to-a-type-error/
