Spring Security 6.4 provides a number of new features.
Below are the highlights of the release, or you can view https://github.com/spring-projects/spring-security/releases[the release notes] for a detailed listing of each feature and bug fix.
== Deprecation Notices
As we get closer to Spring Security 7, it's important to stay up to date on deprecations.
As such, this section points out deprecations in the 6.4 release.
* *Method Security* - `AuthorizationManager#check` is deprecated in favor of `AuthorizationManager#authorize`.
This is primarily to allow the return type to be an interface instead of a concrete class.
If you are invoking `AuthorizationManager#check`, please invoke `AuthorizationManager#authorize` instead.
+
Relatedly, `AuthorizationEventPublisher#publishEvent` that takes an `AuthorizationDecision` is deprecated in favor of a method of the same name that takes an `AuthorizationResult` interface instead.
* *Method Security* - `PrePostTemplateDefaults` is deprecated in favor of the more generic `AnnotationTemplateExpressionDefaults` as there is now meta-annotation property support for `@AuthenticationPrincipal` and `@CurrentSecurityContext` as well.
If you are constructing a `PrePostTemplateDefaults`, change this out for an `AnnotationTemplateExpressionDefaults`.
* *OAuth 2.0* - `NimbusOpaqueTokenIntrospector` has been deprecated in favor of `SpringOpaqueTokenIntrospector` in order to remove Spring Security OAuth 2.0 Resource Server's reliance on the `oidc-oauth2-sdk` package.
If you are constructing a `NimbusOpaqueTokenIntrospector`, replace it with ``SpringOpaqueTokenIntrospector``'s constructor
* *OAuth 2.0* - `DefaultAuthorizationCodeTokenResponseClient`, `DefaultClientCredentialsTokenResponseClient`, `DefaultJwtBearerTokenResponseClient`, `DefaultPasswordTokenResponseClient`, `DefaultRefreshTokenTokenResponseClient`, and `DefaultTokenExchangeTokenResponseClient` are deprecated in favor of their `RestClient` equivalents.
+
Relatedly,`JwtBearerGrantRequestEntityConverter`, `OAuth2AuthorizationCodeGrantRequestEntityConverter`, `OAuth2ClientCredentialsGrantRequestEntityConverter`, `OAuth2PasswordGrantRequestEntityConverter`, `OAuth2RefreshTokenGrantRequestEntityConverter` are deprecated in favor of providing an instance of `DefaultOAuth2TokenRequestParametersConverter` to one of the above token response clients
+
For example, if you have the following arrangement:
+
[source,java]
----
private static class MyCustomConverter
extends AbstractOAuth2AuthorizationGrantRequestEntityConverter<OAuth2AuthorizationCodeGrantRequest> {
@Override
protected MultiValueMap<String, String> createParameters
(OAuth2AuthorizationCodeGrantRequest request) {
MultiValueMap<String, String> parameters = super.createParameters(request);
parameters.add("custom", "value");
return parameters;
}
}
@Bean
OAuth2AccessTokenResponseClient authorizationCode() {
DefaultAuthorizationCodeTokenResponseClient client =
new DefaultAuthorizationCodeTokenResponseClient();
Converter<AuthorizationCodeGrantRequest, RequestEntity<?>> entityConverter =
new OAuth2AuthorizationCodeGrantRequestEntityConverter();
entityConverter.setParametersConverter(new MyCustomConverter());
client.setRequestEntityConverter(entityConverter);
return client;
}
----
+
This configuration is deprecated since it uses `DefaultAuthorizationCodeTokenResponseClient` and `OAuth2AuthorizationCodeGrantRequestEntityConverter`.
The recommended configuration is now:
+
[source,java]
----
private static class MyCustomConverter implements Converter<OAuth2AuthorizationCodeGrantRequest, Map<String, String>> {
@Override
public MultiValueMap<String, String> convert(OAuth2AuthorizeCodeGrantRequest request) {
MultiValueMap<String, String> parameters = OAuth2AuthorizationCodeGrantRequest.defaultParameters(request);
parameters.add("custom", "value");
return parameters;
}
}
@Bean
OAuth2AccessTokenResponseClient authorizationCode() {
RestClientAuthorizationCodeTokenResponseClient client =
new RestClientAuthorizationCodeTokenResponseClient();
client.setParametersConverter(new MyCustomConverter());
return client;
}
----
* *SAML 2.0* - Unversioned OpenSAML implementations of Spring Security SAML 2.0 Service Provider's interfaces have been deprecated in favor of versioned ones.
For example, `OpenSamlAuthenticationTokenConverter` is now replaced by `OpenSaml4AuthenticationTokenConverter` and `OpenSaml5AuthenticationTokenConverter`.
If you are constructing one of these deprecated versions, please replace it with the one that corresponds to the OpenSAML version you are using.
* *SAML 2.0* - Methods surrounding `AssertingPartyDetails` are deprecated in favor of equivalent methods that use the `AssertingPartyMetadata` interface.
* *LDAP* - Usages of `DistinguishedName` are now deprecated in order to align with Spring LDAP's deprecations
