JWT 同一路径回退到 SAML2 的身份验证

Question

I'm using spring-security-saml2-service-provider for authentication in one of my spring boot applications and I'm using a custom JwtAuthorizationFilter (via a http Authentication header) in a different spring boot application.

They both work perfectly on their own.

Now I need to write a spring boot application that uses both of them. If the JWT token is available (Authentication header), then use the JwtAuthorizationFilter , otherwise use saml2Login .

The SAML2 configuration looks like this: (There is no filter , just the saml2Login )

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .csrf()
            .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse()).and()
            .antMatcher("/**").authorizeRequests()
            .antMatchers("/saml2/service-provider-metadata/**").permitAll()
            .antMatchers("/**").authenticated().and()

            // use SAML2
            .saml2Login()
            .addObjectPostProcessor(new ObjectPostProcessor<OpenSamlAuthenticationProvider>() {
                public <O extends OpenSamlAuthenticationProvider> O postProcess(O samlAuthProvider) {
                    samlAuthProvider.setAuthoritiesExtractor(authoritiesExtractor());
                    samlAuthProvider.setAuthoritiesMapper(authoritiesMapper());
                    return samlAuthProvider;
                }
            })
        ;
    }

The JWT configuration looks like this:

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .csrf()
            .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse()).and()
            .antMatcher("/**").authorizeRequests()
            .antMatchers("/**").authenticated().and()

            // use JWT
            .addFilter(new JwtAuthorizationFilter(authenticationManager(), jwtUtil))
        ;
    }

I think I need something like a JwtOrSaml2AuthenticationFilter but don't know how to do that.

The solution is to

1. Duplicate the configuration with @Order and

2. Set a header based requestMatcher before the addFilter

    @EnableWebSecurity public class SecurityConfiguration { @Order(100) // lower number = higher priority @Configuration @RequiredArgsConstructor public static class AppSecurityJWT extends WebSecurityConfigurerAdapter { final JWTUtil jwtUtil; @Override protected void configure(HttpSecurity http) throws Exception { http.csrf().csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse()).and().antMatcher("/**").authorizeRequests().antMatchers("/saml2/service-provider-metadata/**", "/idm-app/**").permitAll().antMatchers("/**").authenticated().and() // This configuration will only be active if the Authorization header is present in the request.requestMatcher(new RequestHeaderRequestMatcher("Authorization")).addFilter(new JwtAuthorizationFilter(authenticationManager(), jwtUtil)); } } @Order(101) @Configuration @RequiredArgsConstructor public static class AppSecuritySAML2 extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http.csrf().csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse()).and().antMatcher("/**").authorizeRequests().antMatchers("/saml2/service-provider-metadata/**", "/idm-app/**").permitAll().antMatchers("/**").authenticated().and() // This whole configuration will only be active, if the previous (100) didn't match.saml2Login() //... ; } }
