java - Spring Boot Security - 默认映射的匿名用户访问/

Question

我们有基于 Spring boot 的应用程序，我们想为匿名用户提供默认/映射访问权限。 我们添加了默认的 index.html(基本页面)。

在 Controller 中

@RequestMapping("/")
public ModelAndView defaultViewManager(HttpServletRequest request) {
    logger.info("Default mapping.");
    ModelAndView modelAndView = new ModelAndView("index");
    return modelAndView;
} 

安全配置

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

private static final String SSO_HEADER = "AUTH_USER";

public static final String ADMIN = "ROLE_ADMIN";
public static final String USER = "ROLE_USER";
public static final String ANONYMOUS = "ROLE_ANONYMOUS";

@Autowired
private PreAuthUserDetailsService userDetailsService;

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
    auth.authenticationProvider(preAuthenticatedAuthProvider());
}

@Bean
public PreAuthenticatedAuthenticationProvider preAuthenticatedAuthProvider() {
    UserDetailsByNameServiceWrapper<PreAuthenticatedAuthenticationToken> wrapper =
            new UserDetailsByNameServiceWrapper<PreAuthenticatedAuthenticationToken>    (userDetailsService);

    PreAuthenticatedAuthenticationProvider authProvider = new PreAuthenticatedAuthenticationProvider();
    authProvider.setPreAuthenticatedUserDetailsService(wrapper);
    return authProvider;
}

@Bean
public RequestHeaderAuthenticationFilter headerAuthFilter() throws Exception {
    RequestHeaderAuthenticationFilter filter = new RequestHeaderAuthenticationFilter();
    filter.setPrincipalRequestHeader(SSO_HEADER);
    filter.setAuthenticationManager(authenticationManagerBean());
    return filter;
}

上面提到的代码可能不是必需的，但作为背景，我们使用 PreAuthenticatedAuthentication Provider

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

    // @formatter:off
    http.addFilter(headerAuthFilter())
        .authorizeRequests()
            .antMatchers("/").permitAll()
            .antMatchers("/admin/**").hasAuthority(ADMIN)
            .antMatchers("/**").hasAuthority(USER)

        .and()
            .logout()
                .deleteCookies("remove")
                .invalidateHttpSession(true)
                .logoutUrl("/logout")
                .logoutSuccessUrl("/login?logout")
        .and()
            .csrf().disable()
            .headers().frameOptions().disable();
    // @formatter:on
}
}

仅供引用，我也添加了拦截器。拦截器似乎被触发，即使使用排除模式也是如此

public void addInterceptors(InterceptorRegistry registry) {     
         registry.addInterceptor(wikiRequestHandlerInterceptor()).
excludePathPatterns("/").addPathPatterns("/**");   

}

在上面的SecurityConfig代码中。我试图允许使用 .antMatchers("/").permitAll() 并添加了 Authority for rest 意味着所有 /** 和 /admin/**。但这是行不通的。请帮助提及正确的 antMatchers 以仅提供对默认/mapping 的匿名访问。

提前致谢。

Answer 1

看起来 antMatchers 需要重新安排以修复优先级。要在 "/" 处允许“所有请求”，首先添加 anyRequest().permitAll()，然后添加受限目录，最后添加包罗万象的 /** 像这样:

http.addFilter(headerAuthFilter())
    .authorizeRequests()
    .anyRequest().permitAll()
    .antMatchers("/admin/**").hasAuthority(ADMIN)
    .antMatchers("/**").hasAuthority(USER)

View Controller 可以设置为直接映射到模板目录中的 indexroot.html(假设是 ThymeLeaf):

public void addViewControllers(ViewControllerRegistry registry) {
    registry.addViewController("/").setViewName("indexroot");
}

我相信拦截器仍然可以用简单的“/”以任何顺序排除:

public void addInterceptors(InterceptorRegistry registry) {
    registry.addInterceptor(wikiRequestHandlerInterceptor())
            .addPathPatterns("/admin/**")
            .excludePathPatterns("/");
}
