Spring Boot and SAML 2.0

问题

Is there a way to integrate SAML 2.0 in a Spring Boot-based application? I'd like to implement my own SP and communicate with a remote IdP.

回答1:

I implemented a sample project in order to show how to integrate Spring Security SAML Extension with Spring Boot.

The source code is published on GitHub:

I recently released a spring boot plugin for this here. It is basically a wrapper around Spring Security SAML that allows for friendlier configuration through a DSL or config properties. Here's an example using the DSL:

@SpringBootApplication
@EnableSAMLSSO
public class SpringBootSecuritySAMLDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringBootSecuritySAMLDemoApplication.class, args);
    }

    @Configuration
    public static class MvcConfig extends WebMvcConfigurerAdapter {

        @Override
        public void addViewControllers(ViewControllerRegistry registry) {
            registry.addViewController("/").setViewName("index");
        }
    }

    @Configuration
    public static class MyServiceProviderConfig extends ServiceProviderConfigurerAdapter {
        @Override
        public void configure(ServiceProviderSecurityBuilder serviceProvider) throws Exception {
            serviceProvider
                .metadataGenerator()
                .entityId("localhost-demo")
            .and()
                .sso()
                .defaultSuccessURL("/home")
                .idpSelectionPageURL("/idpselection")
            .and()
                .logout()
                .defaultTargetURL("/")
            .and()
                .metadataManager()
                .metadataLocations("classpath:/idp-ssocircle.xml")
                .refreshCheckInterval(0)
            .and()
                .extendedMetadata()
                .idpDiscoveryEnabled(true)
            .and()
                .keyManager()
                .privateKeyDERLocation("classpath:/localhost.key.der")
                .publicKeyPEMLocation("classpath:/localhost.cert");

        }
    }
}

That's basically all the code you need.

You'd have to do all the SAML stuff in XML (surprise, surprise). But the rest shouldn't get in the way, just standard Springy, Booty stuff, e.g.

@EnableAutoConfiguration
@Configuration
@ImportResource("my-crazy-ass-saml.xml")
public class Application implements WebMvcSecurityAdapter {

    // set up security filter chain here

}

I tried @vdenotaris' solution, but does not seem to work with current spring-boot, and thus given up that approach.

So as an alternate solution I used shibboleth to do all the SAML stuff using the mod_shib2 module in apache httpd, and run tomcat using mod_jk (mod_proxy_ajp could also be used) behind the said apache instance. Tomcat receives all the required SAML attributes as request attributes, and I only have to store the idp and the user id in the regular user table to connect the internal authentication to the external (I need both SAML and password-based authentication).

I would recommend checking out the Spring SAML extension
