java - 在 Java Config 中 Autowiring Spring Authentication Manager

我设置了一个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，我还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 Autowiring 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 中做到这一点？

最佳答案

我对新的安全 Java 配置不太满意，但这是我从源代码中看到的:

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

此注释导入 AuthenticationConfiguration 也是 @Configuration。任何 @Configuration 也被注册为 bean。所以，你可以从 WebSecurityConfigurerAdapter 这样做:

@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 访问该 authenticationManager :

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

抱歉，我不明白将 AuthenticationManager 注册为 bean 的重点。从这里您无法为他配置别名。

更新

顺便说一句，如果您要将 @Autowired AuthenticationManager 编码到其他某个组件，则 @Value 会出现问题:

@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

如何从自定义 AuthenticationManager 访问现有的 WebSecurityConfigurerAdapter 并配置 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());
  }
}
