【问题描述】：

我正在尝试使用 Spring Security 3.2.4 从我的 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。我可以得到当前的用户名。 预身份验证由 JBoss 7.2 使用 JCIFS (NTLM) 完成。 LDAP 服务器工作正常，所以主机和端口是正确的。 域正确。

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();

我在控制台中得到了什么：

打开调试后，我得到了以下额外详细信息：

其他调试信息：

权限始终为空 mapAuthorities 和 getAuthority 似乎从未被调用过。添加断点根本没有任何作用。

任何帮助将不胜感激。

【参考方案1】：

我不知道你是否解决了你的问题。但是，您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，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，或者参数中没有权限映射到定义为 ROLE_USER 和 ROLE_ADMIN 的 AD 角色。
