导入Spring Context Annotation时出错

Question

When I import a Controller annotation on Spring, the following error occours:

The import org.springframework.stereotype.Controller conflicts with a type defined in the same file

Here goes the (very simple) code of my starting web-MVC project:

package com.company.project.servlet;

import org.springframework.stereotype.Controller;

@Controller
public class Controller {

    public String execute(){
        System.out.println("Controller executing...");
        return("page");
    }
}

As you can see, it is aparently no reason to an error be shown here. Have you any idea on what should be happening? Thanks!

Usefull information: - Eclipse Spring Tool Suite 3.3.0 (over Kepler) - Eclipse jars version 4.0.0.M1 (It should be the lattest versions of all these stuff)

Answer 1

The message says it all :

The import org.springframework.stereotype.Controller conflicts with a type defined in the same file

You have defined a single type in your file: the class Controller , which conflicts with the annotation Controller .

@Controller ---> same name
                     ^
                     |
public class Controller {

Choose another name, or use the fully qualified name of the enum:

@org.springframework.stereotype.Controller 
public class Controller {

Answer 2

@Controller是一个关键字，因此请选择其他类名。
