Spring Security授予的权限始终返回空

Question

我正在尝试使用 Spring Security 3.2.4 从 Spring 4.0.6 应用程序中的 Active Directory 收集用户权限。

一些细节:

• 身份验证有效。我可以获得当前的用户名。
• 预身份验证由 JBoss 7.2 使用 JCIFS (NTLM) 完成。
• LDAP 服务器正常运行，因此主机和端口正确。
• 域名正确。

SecurityConfig.java

@Configuration
@EnableWebMvcSecurity
@PropertySource( "classpath:/resources/ldap-config.properties" )
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Value( "${domain}" )
    private String strDomain;

    @Value( "${ldap.host}" )
    private String strHost;

    @Value( "${ldap.basedn}" )
    private String strBaseDn;

    @Value( "${ldap.userdn}" )
    private String strUserDn;

    @Value( "${ldap.userdn.password}" )
    private String strUserDnPassword;

    @Bean
    public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
        return new PropertySourcesPlaceholderConfigurer();
    }

    @Bean 
    public ActiveDirectoryGrantedAuthoritiesMapper grantedAuthoritiesMapper() {
        return new ActiveDirectoryGrantedAuthoritiesMapper();
    }

    @Bean
    public ActiveDirectoryLdapAuthenticationProvider activeDirectoryLdapAuthenticationProvider() {

        ActiveDirectoryLdapAuthenticationProvider activeDirectoryLdapAuthenticationProvider = new ActiveDirectoryLdapAuthenticationProvider(strDomain, strHost);
        activeDirectoryLdapAuthenticationProvider.setUseAuthenticationRequestCredentials(true);
        activeDirectoryLdapAuthenticationProvider.setConvertSubErrorCodesToExceptions(true);

        activeDirectoryLdapAuthenticationProvider.setAuthoritiesMapper(this.grantedAuthoritiesMapper());

        return activeDirectoryLdapAuthenticationProvider;
    }

    @Override
    public void configure(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception {

        authenticationManagerBuilder
        .authenticationProvider(this.activeDirectoryLdapAuthenticationProvider());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http
            .authorizeRequests()
                .anyRequest().authenticated()
            .and()
            .jee();
    }
}

ActiveDirectoryGrantedAuthoritiesMapper.java

public class ActiveDirectoryGrantedAuthoritiesMapper implements GrantedAuthoritiesMapper {

    // Constants for group defined in LDAP
    private final String ROLE_ADMIN = "A_SPECIFIC_ADMIN_GROUP_IN_AD";
    private final String ROLE_USER = "A_SPECIFIC_GROUP_IN_AD";

    public ActiveDirectoryGrantedAuthoritiesMapper() {
    }

    @Override
    public Collection<? extends GrantedAuthority> mapAuthorities(final Collection<? extends GrantedAuthority> authorities) {

        Set<SecurityContextAuthority> roles = EnumSet.noneOf(SecurityContextAuthority.class);

        for (GrantedAuthority authority : authorities) {

            System.out.println("GrantedAuthority : " + authority.getAuthority());

            if (ROLE_ADMIN.equals(authority.getAuthority())) {
                roles.add(SecurityContextAuthority.ROLE_ADMIN);
            }

            if (ROLE_USER.equals(authority.getAuthority())) {
                roles.add(SecurityContextAuthority.ROLE_USER);
            }
        }

        return roles;
    }

}

SecurityContextAuthority.java

public enum SecurityContextAuthority implements GrantedAuthority {

    ROLE_ADMIN, ROLE_USER;

    @Override
    public String getAuthority() {
        return name();
    }
}

我在控制台中得到的内容:

2014-10-14 14:04:02,557 INFO  [stdout] (http-localhost/127.0.0.1:8080-2) Is Authenticated: true

打开调试后，我获得了以下额外详细信息:

其他调试信息:

• 权威永远是空的
• mapAuthorities 和 getAuthority 似乎从未被调用。添加断点根本没有任何作用。

任何帮助将不胜感激。

Answer 1

不知道你的问题解决了吗？然而，你的描述帮助我解决了我的问题。我几乎根据您的代码实现了权限映射器，并且它工作得很好。我能看到的唯一可能导致权限字段为空的情况是，在调用映射器时该字段为空，或者参数中没有任何权限映射到定义为 ROLE_USER 和 ROLE_ADMIN 的 AD 角色。
