java - Spring Security 为 Authentication.getPrincipal() 返回 guest 而不是 UserDetails

Question

我正在尝试实现 spring security 3.1.0.M1，但我无法让我的应用程序将 Authentication.getPrincipal 设置为我的自定义 UserDetails 实现。当我尝试获取登录用户时，它总是返回“guest”主体。请参阅下面的 getLoggedInUser 方法。

在 Users.java(UserDetails impl)中，getAuthorities 方法永远不会被调用，也许这就是为什么没有分配 user_role 的原因。

也许我配置错误了……我附上了我的实现大纲，希望有人能发现我的错误。感谢您的协助!

public static Users getLoggedInUser() {
    Users user = null;
    Authentication auth = SecurityContextHolder.getContext().getAuthentication();
    if (auth != null && auth.isAuthenticated()) {
        Object principal = auth.getPrincipal();
        if (principal instanceof Users) {
            user = (Users) principal;
        }
    }
    return user;
}

安全上下文文件(删除了 xml 和模式定义):

    <logout logout-url="/auth/logout.html"
            logout-success-url="/" />
    <anonymous username="guest" granted-authority="ROLE_ANONYMOUS"/>
    <remember-me user-service-ref="userManager" key="valid key here"/>
</http>
<!-- Configure the authentication provider -->
<authentication-manager>
    <authentication-provider user-service-ref="userManager">
            <password-encoder ref="passwordEncoder" />
    </authentication-provider>
</authentication-manager>

用户详细信息实现(Users.java):

public class Users implements Serializable, UserDetails {
    public Collection<GrantedAuthority> getAuthorities() {
     List<GrantedAuthority> auth = new ArrayList<GrantedAuthority>();
    auth.add(new GrantedAuthorityImpl("ROLE_USER"));
    return auth;
}

user-service-ref="userManager"(UserManagerImpl.java):

 public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException, DataAccessException {
    Users user = null;
    try {
        user = userDAO.findByUsername(username);
    } catch (DataAccessException ex) {
        throw new UsernameNotFoundException("Invalid login", ex);
    }
    if (user == null) {
        throw new UsernameNotFoundException("User not found.");
    }
    return user;
}

你没有在这一行收到编译错误:auth.add("ROLE_USER");？

我认为应该是:auth.add(new SimpleGrantedAuthority("ROLE_USER"));
