Java Springframework用户详细信息服务错误

我正在尝试使用spring框架创建自己的UserDetails服务

我创建了以下简单的类，但出现了一个错误：

无法将[com.mycompany.project.MyDetailsService]类型的值转换为所需的类型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
    }
}

如果有帮助的话，我可以包括填充堆栈跟踪。它很长，不容易放入框中，因此这里是堆栈跟踪之前错误消息的全文

我们可以看一下您的OWFsecurityContext.xml文件的片段吗？当然可以。我不知道你需要多少，但我把大部分都贴在上面了。请让我知道填写任何省略号是否有帮助。谢谢。我看不出有什么问题。值得一提的是，CasAuthenticationProvider（这是虚拟的）确实说setUserDetailsService已被弃用，您应该使用setAuthenticationUserDetailsService，它接受不同的用户详细信息服务。看看这是否是问题所在-我不能说。谢谢你的帮助。我尝试将类更改为实现AuthenticationUserDetailsService，并将安全上下文更改为使用AuthenticationUserDetailsService，但我仍然收到类似的错误，只是这次它无法转换为AuthenticationUserDetailsService。
