Springframework UserDetailsS​​ervice错误

Question

我正在尝试使用spring框架创建自己的UserDetailsS​​ervice。

我做了以下简单的课程，但我收到了一个错误：Cannot convert value of type [com.mycompany.project.MyDetailsService] to required type org.springframework.security.core.userdetails.UserDetailsService]

全班：

package com.mycompany.myproject;

import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.Collection;
import java.util.Enumeration;
import java.util.HashMap;
import java.util.Map;
import java.util.Properties;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.dao.DataAccessException;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;


public class MyDetailsService implements UserDetailsService{
    private static final Log log = LogFactory.getLog(MyDetailsService.class);

    @Override
    public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException, DataAccessException {        
        return null; //It'll do something here later
    }
}

如果有用，我可以包括填充堆栈跟踪。它只是很长，并且不容易放入盒子中，所以这里是堆栈跟踪之前的错误消息的全文。
