||
== Overview | ||
|
||
This document is about promoting the http://download.eclipse.org/microprofile/microprofile-rest-client-4.0/microprofile-rest-client-spec-4.0.html[MicroProfile REST Client 4.0] | ||
from a stability level of `preview` to a stability level of `default`. | ||
|
||
As you'll see in the release notes below, not much was added to the MicroProfile REST Client 4.0 API. There are only two | ||
new methods added to the `RestClientBuilder` API. | ||
|
||
=== User Stories | ||
|
||
A user wants to use the MicroProfile REST Client version 4.0 or use MicroProfile Platform 7.0. | ||
|
||
== Issue Metadata | ||

=== Related Issues | ||
|
||
* https://issues.redhat.com/browse/WFLY-19866[WFLY-19866] - Promotion from `preview` to `default` | ||
* https://issues.redhat.com/browse/WFLY-19589[WFLY-19589] - Integration of MicroProfile REST Client 4.0 into WildFly Preview | ||
* https://issues.redhat.com/browse/WFLY-19588[WFLY-19588] - MicroProfile Platform 7.0 | ||
|
||
=== Affected Projects or Components | ||
|
||
* https://github.com/wildfly/wildfly | ||
|
||
=== Other Interested Projects | ||
|
||
Any project wanting either the MicroProfile REST Client version 4.0 or MicroProfile Platform 7.0. There are two new | ||
methods on the `RestClientBuilder` for user convenience. | ||
|
||
* `baseUri(String)`: This was added as an alternative to `baseUri(URI)` and `baseUrl(URL)`. It allows a simple | ||
`java.lang.String` to be used instead of having to create a `java.net.URI` or `java.net.URL` first. | ||
* `header(String, Object)`: Adds a header to which will be used on all requests with the built client. Headers added via | ||
this method will be merged with the headers added via `@ClientHeaderParam` annotations, `@HeaderParam` annotations, and | ||
`ClientHeadersFactory` implementations. | ||
|
||
=== Relevant Installation Types | ||
|
||
* Traditional standalone server (unzipped or provisioned by Galleon) | ||
* Managed domain | ||
* OpenShift Source-to-Image (S2I) | ||
* Bootable jar | ||
|
||
== Requirements | ||
|
||
The MicroProfile REST Client API and the RESTEasy MicroProfile implementation must be upgraded to be compliant with the | ||
https://download.eclipse.org/microprofile/microprofile-7.0/microprofile-spec-7.0.html[MicroProfile 7.0 Specification]. | ||
|
||
There are no specific integration requirements as this is about upgrading an API and implementation. | ||
|
||
=== Changed requirements | ||
|
||
The only change here is migrating from the MicroProfile REST Client 3.0 API to the MicroProfile REST Client 4.0 API and | ||
RESTEasy MicroProfile 2.1 to RESTEasy MicroProfile 3.0. | ||
|
||
=== Non-Requirements | ||
|
||
N/A | ||
|
||
=== Future Work | ||
|
||
N/A | ||
|
||
== Backwards Compatibility | ||
|
||
There are no backwards compatibility issues. The new API has only added two new methods to the `RestClientBuilder` API. | ||
|
||
=== Default Configuration | ||
|
||
There are currently no configuration options for the integration and no new ones will be added. | ||
|
||
=== Importing Existing Configuration | ||
|
||
There is no issue using a current WildFly configuration with this change. | ||
|
||
=== Deployments | ||
|
||
There is no incompatible changes to the API or implementation. Deployments will simply see the newer versions available | ||
on their class path. | ||
|
||
=== Interoperability | ||
|
||
N/A | ||
|
||
== Implementation Plan | ||
|
||
The implementation plan is to simply upgrade versions of the required components. | ||
|
||
One note is that TCK POM configuration needed some changes. However, that is only for testing. | ||
|
||
== Admin Clients | ||
|
||
This change has no affect on admin clients. There are no model changes. | ||
|
||
== Security Considerations | ||
|
||
There would be no changes to security considerations for this upgrade. | ||
|
||
[[test_plan]] | ||
== Test Plan | ||
|
||
The test plan here is to rely on the MicroProfile REST Client TCK and the tests in | ||
https://github.com/resteasy/resteasy-microprofile[RESTEasy MicroProfile]. There are TCK tests for all the new features | ||
and some new TCK tests that were previously missed in the last TCK release. | ||
|
||
Some of the other MicroProfile TCK's and integration tests use the the MicroProfile REST Client. Some indirect testing | ||
will happen there as well. | ||
|
||
These TCK's run as part of a full WildFly build. | ||
|
||
There will not be any manual testing at this time as these new features are simply convenience methods for existing | ||
methods. New TCK tests were also added for these. Therefore, there is some build-in integration testing. | ||
|
||
== Community Documentation | ||
|
||
There seems to be no documentation for the MicroProfile REST Client short of noting the version. The version matrix | ||
documentation will be updated. | ||
|
||
== Release Note Content | ||
|
||
In this release there was an alignment with https://jakarta.ee/specifications/restful-ws/3.1/jakarta-restful-ws-spec-3.1[Jakarta RESTful Web Services 3.1] | ||
to be compatible with Jakarta EE 10. | ||
|
||
* There was a clarification about closing the REST client when being injected via CDI (https://github.com/eclipse/microprofile-rest-client/issues/348[348]). | ||
* The RestClientBuilder added a new method, baseUri(String) (https://github.com/eclipse/microprofile-rest-client/issues/334[334]). | ||
* The RestClientBuilder also added a new header(String, Object) method for adding headers to the built REST Client. The headers will be merged with headers added via other means (https://github.com/eclipse/microprofile-rest-client/issues/283[283]). | ||
|
||
Two New Helper Methods: | ||
|
||
* `baseUri(String)`: This was added as an alternative to `baseUri(URI)` and `baseUrl(URL)`. It allows a simple | ||
`java.lang.String` to be used instead of having to create a `java.net.URI` or `java.net.URL` first. | ||
* `header(String, Object)`: Adds a header to which will be used on all requests with the built client. Headers added via | ||
this method will be merged with the headers added via `@ClientHeaderParam` annotations, `@HeaderParam` annotations, and | ||
`ClientHeadersFactory` implementations. |
