如何在Spring Boot中设置基于头部的预身份验证？

Question

我的应用程序从Oracle Access Manager SSO获取一个带有用户名的AUTH_用户请求标头。Spring Security“附加主题”2.2。1有一个“PreAuth”的示例，这似乎是我需要的，但不是一个完整的工作示例。

下面的片段来自文档/示例，而不是基于注释的配置。

Siteminder示例配置-使用带有RequestHeaderAuthenticationFilter和PreAuthenticationDauthenticationProvider的XML以及UserDetails服务来查找用户。

这如何映射到基于Java的配置？

<security:http>
  <!-- Additional http configuration omitted -->
  <security:custom-filter position="PRE_AUTH_FILTER" ref="siteminderFilter" />
</security:http>

<bean id="siteminderFilter" class="org.springframework.security.web.authentication.preauth.RequestHeaderAuthenticationFilter">
  <property name="principalRequestHeader" value="AUTH_USER"/>
  <property name="authenticationManager" ref="authenticationManager" />
</bean>

<bean id="preauthAuthProvider" class="org.springframework.security.web.authentication.preauth.    PreAuthenticatedAuthenticationProvider">
  <property name="preAuthenticatedUserDetailsService">
    <bean id="userDetailsServiceWrapper"
          class="org.springframework.security.core.userdetails.UserDetailsByNameServiceWrapper">
      <property name="userDetailsService" ref="userDetailsService"/>
    </bean>
  </property>
</bean>

<security:authentication-manager alias="authenticationManager">
   <security:authentication-provider ref="preauthAuthProvider" />
</security:authentication-manager>

SpringSecurityPreauth示例有一个完全不同的设置（XML配置甚至更吓人）。未提及预验证过滤器或如何设置标题名称。

@Configuration
@EnableWebMvcSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/login","/resources/**").permitAll()
                .anyRequest().authenticated()
                .and()
            .jee()
                .mappableRoles("USER","ADMIN");
    }
}

spring boot示例web secure扩展了WebMVCConfigureAdapter而不是WebSecurityConfigureAdapter，只进行基于表单的基本登录，没有关于如何从预授权用户头获取用户ID的信息。

public class SampleWebSecureApplication extends WebMvcConfigurerAdapter {

... omitted...

    @Bean
    public ApplicationSecurity applicationSecurity() {
        return new ApplicationSecurity();
    }

    @Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
    protected static class ApplicationSecurity extends WebSecurityConfigurerAdapter {

        @Autowired
        private SecurityProperties security;

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.authorizeRequests().anyRequest().fullyAuthenticated().and().formLogin()
                    .loginPage("/login").failureUrl("/login?error").permitAll();
        }
    }

}

我读过很多参考文献/文章，但它们似乎与当前代码和Spring boot无关，因此我一直在努力理解如何配置应用程序预验证安全性。

这是我基于注入的userService配置预验证安全性的方法：

@Configuration
@EnableWebSecurity
@EnableWebMvcSecurity
@EnableGlobalMethodSecurity(jsr250Enabled = true, securedEnabled = true, prePostEnabled = true, proxyTargetClass = true)
public class ApplicationSecurity extends WebSecurityConfigurerAdapter {

    private static final Logger LOG = Logger.getLogger(ApplicationSecurity.class.getName());

    @Autowired
    private UserService userService; // implements AuthenticationUserDetailsService...

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        LOG.info("configure autentication provider with custom userService");
        PreAuthenticatedAuthenticationProvider paaProvider = new PreAuthenticatedAuthenticationProvider();
        paaProvider.setPreAuthenticatedUserDetailsService(userService);
        auth.authenticationProvider(paaProvider);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        LOG.info("configure autentication filter");
        // ...
    }

}
