如何将UserDetailsService下面的自定义添加到此Spring OAuth2示例中？

默认值user和默认值在应用程序password的application.properties文件中定义authserver。

不过，我想以下自定义添加UserDetailsService到该demo包中的authserver应用程序用于测试目的：

package demo;

import java.util.List;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.AuthorityUtils;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.provisioning.UserDetailsManager;
import org.springframework.stereotype.Service;

@Service
class Users implements UserDetailsManager {

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        String password;
        List<GrantedAuthority> auth = AuthorityUtils.commaSeparatedStringToAuthorityList("ROLE_USER");
        if (username.equals("Samwise")) {
            auth = AuthorityUtils.commaSeparatedStringToAuthorityList("ROLE_HOBBIT");
            password = "TheShire";
        }
        else if (username.equals("Frodo")){
            auth = AuthorityUtils.commaSeparatedStringToAuthorityList("ROLE_HOBBIT");
            password = "MyRing";
        }
        else{throw new UsernameNotFoundException("Username was not found. ");}
        return new org.springframework.security.core.userdetails.User(username, password, auth);
    }

    @Override
    public void createUser(UserDetails user) {// TODO Auto-generated method stub
    }

    @Override
    public void updateUser(UserDetails user) {// TODO Auto-generated method stub
    }

    @Override
    public void deleteUser(String username) {// TODO Auto-generated method stub
    }

    @Override
    public void changePassword(String oldPassword, String newPassword) {
        // TODO Auto-generated method stub
    }

    @Override
    public boolean userExists(String username) {
        // TODO Auto-generated method stub
        return false;
    }
}

如您所见，这UserDetailsService还不autowired是，它故意使用不安全的密码，因为它仅用于测试目的。

需要什么样的具体变化来进行 GitHub的示例应用程序，以便用户可以登录为username=Samwise与password=TheShire，或username=Frodo用password=MyRing？
是否需要对AuthserverApplication.java其他地方进行更改？

建议：

在春天的OAuth2开发指南说，使用一个GlobalAuthenticationManagerConfigurer配置UserDetailsService全球。但是，使用谷歌搜索这些名称所产生的效果会有所帮助。

另外，使用内部弹簧安全性INSTEAD OF
OAuth的其他应用程序使用以下语法来连接UserDetailsService，但是我不确定如何将其语法调整为当前OP：

@Order(Ordered.HIGHEST_PRECEDENCE)
@Configuration
protected static class AuthenticationSecurity extends GlobalAuthenticationConfigurerAdapter {

    @Autowired
    private Users users;

    @Override
    public void init(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(users);
    }
}

我试着用@Autowire里面的OAuth2AuthorizationConfig连接Users到AuthorizationServerEndpointsConfigurer如下：

@Autowired//THIS IS A TEST
private Users users;//THIS IS A TEST

@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
   endpoints.authenticationManager(authenticationManager)
        .accessTokenConverter(jwtAccessTokenConverter())
        .userDetailsService(users)//DetailsService)//THIS LINE IS A TEST
        ;
}

但是Spring Boot日志表明Samwise找不到该用户，这意味着该用户UserDetailsService未成功连接。这是Spring
Boot日志的相关摘录：

2016-04-20 15:34:39.998 DEBUG 5535 --- [nio-9999-exec-9] o.s.s.a.dao.DaoAuthenticationProvider    :  
        User 'Samwise' not found
2016-04-20 15:34:39.998 DEBUG 5535 --- [nio-9999-exec-9]   
        w.a.UsernamePasswordAuthenticationFilter :  
        Authentication request failed:  
        org.springframework.security.authentication.BadCredentialsException:  
        Bad credentials

我还能尝试什么？
