Question

我尝试使用Spring Security和Hibernate连接我的应用程序。但是上下文没有看到bean myUserDetailsService。我已经尝试了几种方法来解决这个问题而没有结果。我想使用注释方式，但我也尝试过XML方式。下面是我的配置：

MyUserDetailsService.java

@Service("userDetailsService") 
@Transactional
public class MyUserDetailsService implements UserDetailsService {

    @Autowired
    private UserRepository userRepository;

    @Override
    public UserDetails loadUserByUsername(final String userName)
            throws UsernameNotFoundException {

        com.engineering.pawel.pojo.User user = userRepository
                .findByUserName(userName);
        List<GrantedAuthority> authorities = buildUserAuthority(user
                .getUserRole());

        return buildUserForAuthentication(user, authorities);
    }

    private User buildUserForAuthentication(
            com.engineering.pawel.pojo.User user,
            List<GrantedAuthority> authorities) {
        return new User(user.getNick(), user.getPassword(), true, true, true,
                true, authorities);
    }

    private List<GrantedAuthority> buildUserAuthority(Set<UserRole> userRoles) {

        Set<GrantedAuthority> setAuths = new HashSet<GrantedAuthority>();

        for (UserRole userRole : userRoles) {
            setAuths.add(new SimpleGrantedAuthority(userRole.getRole()));
        }

        List<GrantedAuthority> Result = new ArrayList<GrantedAuthority>(
                setAuths);

        return Result;
    }
}

Answer 1

而不是

<authentication-manager>
    <authentication-provider user-service-ref="myUserDetailsService" >
        <password-encoder hash="md5" />    
    </authentication-provider>
</authentication-manager>

你试过吗

<authentication-manager>
    <authentication-provider user-service-ref="userDetailsService" >
        <password-encoder hash="md5" />    
    </authentication-provider>
</authentication-manager>

这是因为bean的服务注释是

@Service("userDetailsService")
