Spring Security 5.0.0 M4 Released

Releases | Rob Winch | September 15, 2017 | ...

On behalf of the community, I’m pleased to announce the release of Spring Security 5.0.0 M4. This release includes bug fixes, new features, and is based off of Spring Framework 5.0.0 RC4. You can find complete details in the changelog. The highlights of the release include:

OAuth2 / OIDC

OAuth2 Login Java Config

There are a number of improvements to the HttpSecurity.oauth2Login() DSL.

You can now configure the Token Endpoint with a custom implementation of an AuthorizationGrantTokenExchanger or SecurityTokenRepository<AccessToken>, as follows:

protected void configure(HttpSecurity http) throws Exception {

We’ve also added the capability of customizing the request paths for the Authorization Endpoint and Redirection Endpoint:

protected void configure(HttpSecurity http) throws Exception {
        .requestMatcher(new AntPathRequestMatcher("/custom-path/{clientAlias}"))
        .requestMatcher(new AntPathRequestMatcher("/custom-path/callback/{clientAlias}"));

As with all AbstractAuthenticationProcessingFilter 's in Spring Security, you can also set a custom AuthenticationSuccessHandler and AuthenticationFailureHandler:

protected void configure(HttpSecurity http) throws Exception {

Security Token Repository

We’ve introduced the SecurityTokenRepository<T extends SecurityToken> abstraction, which is responsible for the persistence of SecurityToken 's.

The initial implementation InMemoryAccessTokenRepository provides the persistence of AccessToken 's. In an upcoming release we’ll also provide an implementation that supports the persistence of Refresh Token’s.

ID Token and Claims

A couple of minor improvements were introduced to the IdToken along with some final implementation details for JwtClaimAccessor, StandardClaimAccessor and IdTokenClaimAccessor, which provide convenient access to claims in their associated constructs, for example, Jwt, IdToken, UserInfo.

Authorization Request Improvements

We’ve added the capability for an AuthorizationRequestRepository to persist the Authorization Request to a Cookie. The current default implementation persists in the HttpSession, however, a custom implementation may be provided to persist to a Cookie instead.

Support was also added for URI variables configured in the redirect-uri for the AuthorizationCodeRequestRedirectFilter.

OAuth2 Client Properties

There were a couple of minor updates to the properties for configuring an OAuth 2.0 Client. The configuration below outlines the current structure. You will notice that there is support for configuring multiple clients, for example, google, github, okta, etc.

        client-id: your-app-client-id
        client-secret: your-app-client-secret
        client-authentication-method: basic
        authorization-grant-type: authorization_code
        redirect-uri: "{scheme}://{serverName}:{serverPort}{contextPath}/oauth2/authorize/code/{clientAlias}"
        scope: openid, profile, email, address, phone
        authorization-uri: "https://accounts.google.com/o/oauth2/v2/auth"
        token-uri: "https://www.googleapis.com/oauth2/v4/token"
        user-info-uri: "https://www.googleapis.com/oauth2/v3/userinfo"
        user-name-attribute-name: "sub"
        jwk-set-uri: "https://www.googleapis.com/oauth2/v3/certs"
        client-name: Google
        client-alias: google

A complete example for using the new Spring Security OAuth 2.0 / OpenID Connect 1.0 login feature can be found in the Spring Security samples at oauth2login. The guide will walk you through the steps for setting up the sample application for OAuth 2.0 login using an external OAuth 2.0 or OpenID Connect 1.0 Provider.

Reactive Security

Reactive Method Security

Spring Security’s Reactive support now includes method security by leveraging Reactor’s Context. The highlights are below, but you can find a complete example of it in action in samples/javaconfig/hellowebflux-method

The first step is to use @EnableReactiveMethodSecurity to enable support for @PreAuthorize and @PostAuthorize annotations. This step ensures that the objects are properly proxied.

public class SecurityConfig {

The next step is to create a service that is annotated with @PreAuthorize or @PostAuthorize. For example:

public Mono<String> findMessage() {

Spring Security’s WebFlux support will then ensure that the Reactor Context will be populated with the current user which is used to determine if access is granted or denied.

Spring Security’s standard @WithMockUser and related annotations has been updated to work with Reactive Method Security. For example:

// ...
public class HelloWorldMessageServiceTests {
  HelloWorldMessageService messages;

@Test public void messagesWhenNotAuthenticatedThenDenied() { StepVerifier.create(this.messages.findMessage()) .expectError(AccessDeniedException.class) .verify(); }

@Test @WithMockUser public void messagesWhenUserThenDenied() { StepVerifier.create(this.messages.findMessage()) .expectError(AccessDeniedException.class) .verify(); }

@Test @WithMockUser(roles = "ADMIN") public void messagesWhenAdminThenOk() { StepVerifier.create(this.messages.findMessage()) .expectNext("Hello World!") .verifyComplete(); } }

The test support also works nicely with TestWebClient. For example:

// ...
public class HelloWebfluxMethodApplicationTests {
  ApplicationContext context;

WebTestClient rest;

@Before public void setup() { this.rest…

Spring Session 2.0.0 M4

Releases | Rob Winch | September 15, 2017 | ...

On behalf of the community I’m pleased to announce the release of Spring Session 2.0.0.M4. This release is focused primarily on refining WebFlux support. The highlights are:

Simplified WebFlux Configuration

Configuring Spring Session for WebFlux is simplified to be:

public class HelloWebfluxSessionConfig {

  public MapReactorSessionRepository reactorSessionRepository() {
    return new MapReactorSessionRepository(new ConcurrentHashMap<>());

You can also switch the strategy for resolving session id’s by simply adding a WebSessionIdResolver Bean. For example, to switch from using cookies to resolve the session id to using headers, you can use Spring Framework’s new HeaderWebSessionIdResolver

  • Reactive WebFlux Channel Adapters has been extracted to the separate spring-integration-webflux module to distinguish Servlet-based MVC configuration from the Reactive foundation.

  • The EmbeddedJsonHeadersMessageMapper is introduced to allow embedding message headers together with the payload into packages for target protocols which doesn’t support headers natively, for example TCP/IP, MQTT, AWS Kinesis and Apache Kafka before version 0.11.x.

  • The java.util.function.Supplier can now act as a MessageSource:
