Configuring Apache Shiro with Google Guice Servlet

I'm starting to use Guice/Shiro instead of Spring/Spring Security. I have looked examples from Shiro site, and all configuration examples are made as INI-file examples. Is it possible to configure Shiro in plain Java, as Guice Servlets are meant to be configured?

Yes it is possible, but requires some glue code if you want Guice to create your Realms.

  1. Bind Realm implementation:
    bind(Realm.class).to(MyRealm.class).in(Singleton.class);
  1. Bind WebSecurityManager:
    @Provides @Singleton WebSecurityManager securityManager(Realm realm) {
      DefaultWebSecurityManager sm = new DefaultWebSecurityManager();
      sm.setRealm(realm);
      return sm;
    }
  1. Subclass one of Shiro filters so you can use Guice provided WebSecurityManager:
    public class SecurityFilter extends IniShiroFilter {

      static class SecurityManagerFactory extends WebIniSecurityManagerFactory {

        private final WebSecurityManager securityManager;

        public SecurityManagerFactory(WebSecurityManager securityManager) {
          this.securityManager = securityManager;
        }

        public SecurityManagerFactory(WebSecurityManager securityManager, Ini ini) {
          super(ini);
          this.securityManager = securityManager;
        }

        @Override
        protected SecurityManager createDefaultInstance() {
          return securityManager;
        }
      }

      private final Provider<WebSecurityManager> securityManager;

      @Inject
      SecurityFilter(Provider<WebSecurityManager> securityManager) {
        super();
        this.securityManager = securityManager;
      }


      protected Map<String, ?> applySecurityManager(Ini ini) {
        SecurityManagerFactory factory;
        if (ini == null || ini.isEmpty()) {
          factory = new SecurityManagerFactory(securityManager.get());
        } else {
          factory = new SecurityManagerFactory(securityManager.get(), ini);
        }
        setSecurityManager((WebSecurityManager) factory.getInstance());
        return factory.getBeans();
      }
    }
  1. Configure your filter:
    Joiner lines = Joiner.on("\n");
    Map<String, String> config = ImmutableMap.of("config", lines.join(
        "; here you can provide additional ini",
        "[roles]",
        "admin = *",
        "[urls]",
        "/secure/** = authcBasic"
    ));
    filter("/*").through(SecurityFilter.class, config);
