在Java Config中自动装配Spring Authentication Manager

Question

我已经设置了自定义身份验证提供程序:

@Configuration
@EnableWebSecurity
@EnableGlobalAuthentication
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    @Qualifier("samlAuthenticationProvider")
    SAMLAuthenticationProvider samlAuthenticationProvider;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        /**
         * Do your stuff here
         */
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(samlAuthenticationProvider);
    }   

}

现在,我想为身份验证管理器设置一个别名,然后我想在另一个bean定义中自动装配它.

例如:

<!-- Register authentication manager with SAML provider -->
<security:authentication-manager alias="authenticationManager">
    <security:authentication-provider
        ref="samlAuthenticationProvider" />
</security:authentication-manager>

<!-- Processing filter for WebSSO Holder-of-Key profile -->
<bean id="samlWebSSOHoKProcessingFilter"
    class="org.springframework.security.saml.SAMLWebSSOHoKProcessingFilter">
    <property name="authenticationManager" ref="authenticationManager" />
    <property name="authenticationSuccessHandler" ref="successRedirectHandler" />
</bean>

有没有办法只在Java Config中这样做？

Answer 1

我不熟悉新的安全Java配置,但这是我从源代码中看到的:

@Import(AuthenticationConfiguration.class)
public @interface EnableGlobalAuthentication {}

这个注释也会导入AuthenticationConfiguration谁@Configuration.Any也@Configuration被注册为bean.所以,你可以这样做WebSecurityConfigurerAdapter:

@Autowired
public void setAuthenticationConfiguration(AuthenticationConfiguration authenticationConfiguration) {
     this.authenticationConfiguration = authenticationConfiguration;
}

并访问AuthenticationManager:

this.authenticationConfiguration.getAuthenticationManager();

从xml的角度来看,您可以使用SpEL来访问它authenticationManager:

<property name="authenticationManager" value="#{authenticationConfiguration.authenticationManager}" />

对不起,我没有看到重点,AuthenticationManager注册为bean的位置.从这里你不能为他配置别名.

UPDATE

顺便说一句,如果你要@Autowired在AuthenticationManager其他一些组成部分,@Value前来resque:

@Value("#{authenticationConfiguration.authenticationManager}")
private AuthenticationManager authenticationManager;

UPDATE2

找到了WebSecurityConfigurerAdapter.源代码和JavaDocs:

/**
 * Override this method to expose the {@link AuthenticationManager} from
 * {@link #configure(AuthenticationManagerBuilder)} to be exposed as
 * a Bean. For example:
 *
 * <pre>
 * &#064;Bean(name name="myAuthenticationManager")
 * &#064;Override
 * public AuthenticationManager authenticationManagerBean() throws Exception {
 *     return super.authenticationManagerBean();
 * }
 * </pre>
 *
 * @return the {@link AuthenticationManager}
 * @throws Exception
 */
public AuthenticationManager authenticationManagerBean() throws Exception {
    return new AuthenticationManagerDelegator(authenticationBuilder);
}

UPDATE3

如何AuthenticationManager从自定义WebSecurityConfigurerAdapter和配置访问现有的SAMLWebSSOHoKProcessingFilter？

@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

  @Bean
  public SAMLWebSSOHoKProcessingFilter samlFilter() {
    SAMLWebSSOHoKProcessingFilter samlFilter = new SAMLWebSSOHoKProcessingFilter();
    samlFilter.setAuthenticationManage(authenticationManager());
    .......
    return samlFilter;
  }

  @Override  
  protected void configure(HttpSecurity http) throws Exception {
      http.addFilter(samlFilter());
  }
}
