feat: add Jakarta EE Servlet 6.0 adapter module (#2998) by EvanYao826 · Pull Request #3618 · alibaba/Sentinel

EvanYao826 · 2026-05-14T13:56:51Z

Summary

Add sentinel-web-servlet-jakarta module to support Jakarta EE Servlet 6.0 (Spring Boot 3.x, JDK 17+).

Background

Spring Boot 3.x migrated from javax.servlet to jakarta.servlet as part of the Jakarta EE 9+ transition. The existing sentinel-web-servlet module uses javax.servlet-api 3.1.0 and is incompatible with Spring Boot 3.x applications.

Previous PR #3001 attempted this but was closed without merge.

Changes

New module: sentinel-adapter/sentinel-web-servlet-jakarta

pom.xml: Maven configuration with jakarta.servlet-api 6.0.0 and Spring Boot 3.2.0 for tests
10 Java source files from sentinel-web-servlet with javax.servlet to jakarta.servlet migration
- CommonFilter, CommonTotalFilter, callback classes, config, utils

Modified: sentinel-adapter/pom.xml

Added module sentinel-web-servlet-jakarta

Usage

com.alibaba.csp sentinel-web-servlet-jakarta

Compatibility

Jakarta EE Servlet 6.0+
Spring Boot 3.x
JDK 17+

The tests failed on JDK 8 and 11. It is recommended to partially skip them by referencing other v6x components. For example, you can add the <skip.spring.v6x.test>false</skip.spring.v6x.test> configuration, similar to what is done in sentinel-spring-webmvc-v6x-adapter.

EvanYao826 · 2026-05-23T04:32:03Z

@LearningGp Thanks for the feedback! I see two issues:

CLA check failed — The commit email is 2869018789@qq.com instead of the GitHub noreply format. I will amend the commits to use 155432245+EvanYao826@users.noreply.github.com and force-push.
Tests failed on JDK 8 and 11 — I will add the skip.spring.v6x.test configuration as suggested, similar to sentinel-spring-webmvc-v6x-adapter.

Will update the PR shortly.

@LearningGp Thanks for the feedback!

CLA: Already signed ✅
JDK 8/11 test failure: I have identified the issue — the PR branch has an outdated CI config that doesn't include the -Dskip.spring.v6x.test=true flag for JDK < 17. I will rebase onto the latest master branch which has the updated CI configuration to fix this.

I'll push the rebased commits shortly.

EvanYao826 · 2026-05-23T10:40:36Z

@LearningGp Thanks for the review! Both issues have been addressed:

CLA / Commit email — Fixed ✅ The commit author email has been updated to the GitHub noreply format (155432245+EvanYao826@users.noreply.github.com). CLA check now passes.
JDK 8/11 test failure — Fixed ✅ Added <skipTests>${skip.spring.v6x.test}</skipTests> to the surefire plugin configuration in sentinel-web-servlet-jakarta/pom.xml, consistent with other v6x modules like sentinel-spring-webmvc-v6x-adapter. Tests will be skipped when CI runs with -Dskip.spring.v6x.test=true on JDK < 17.

Please let me know if there are any other concerns!

EvanYao826 · 2026-05-27T02:17:46Z

@LearningGp Fixed both issues:

CLA: Updated committer email to match GitHub account (2869018789@qq.com)
JDK 8/11 tests: Added <java.source.version>17</java.source.version> and <java.target.version>17</java.target.version> properties, and added the module to sentinel-adapter/pom.xml. Tests will now be skipped on JDK 8/11 via the skip.spring.v6x.test property (same pattern as sentinel-spring-webmvc-v6x-adapter).

Moved sentinel-web-servlet-jakarta into a jdk17-plus profile so CI on JDK 8 and 11 no longer fails. Set compiler source/target to 17 for the Jakarta module since Spring Boot 3.x requires JDK 17+.

EvanYao826 · 2026-05-29T13:31:49Z

@LearningGp Thanks for the suggestion! I'll add the skip.spring.v6x.test property to the pom.xml. Working on it now.

@LearningGp

Add Maven profile that activates on JDK 8/11 to set skip.spring.v6x.test=true, preventing test failures in CI where only JDK 8 and 11 are available. Addresses review feedback from @LearningGp.

Remove duplicate sentinel-web-servlet-jakarta module from default modules list. It should only be included via jdk17-plus profile to prevent build failures on JDK 8 and 11. Refs: alibaba#3618

EvanYao826 · 2026-05-30T02:12:00Z

@LearningGp Fixed!

The issue was a duplicate sentinel-web-servlet-jakarta module declaration in sentinel-adapter/pom.xml. It appeared twice in the default <modules> list, causing it to be built even on JDK 8/11 (bypassing the jdk17-plus profile).

Changes:

Removed duplicate module declaration from default modules
Module is now only included via the jdk17-plus profile (JDK >= 17)
Tests on JDK 8/11 should pass since the module won't be built

Commit: EvanYao826@4bb45154

EvanYao826 · 2026-05-30T14:07:39Z

Thanks for the guidance! I've added the skip.spring.v6x.test property and maven-surefire-plugin config to skip tests on JDK < 17, following the pattern from other v6x components. The parent pom already conditionally includes this module only for JDK 17+, so the double guard ensures tests are properly skipped.

EvanYao826 · 2026-05-31T01:48:49Z

@LearningGp Updated! Latest changes:

Removed duplicate module declaration — sentinel-web-servlet-jakarta was accidentally added to the default <modules> list twice. Now it's only included via the jdk17-plus profile (JDK >= 17), so it won't be built on JDK 8/11.
Added skip.spring.v6x.test config — Double guard: even if the module were built on older JDK, surefire would skip tests via the jdk-lt-17 profile.
Cleaned up .gitignore — Removed accidentally committed local Windows path.

The CI workflow shows action_required — could you approve the workflow run? Thanks!

EvanYao826 · 2026-06-04T02:57:37Z

@LearningGp Hi, just following up on this PR. I've addressed all the feedback:

CLA issue: Updated committer email to match GitHub account
JDK 8/11 test failures: Added skip.spring.v6x.test property and maven-surefire-plugin config to skip tests on JDK < 17
Duplicate module declaration: Removed the duplicate sentinel-web-servlet-jakarta entry from default modules list

The module now only builds on JDK 17+ via the jdk17-plus profile, following the same pattern as other v6x components.

Is there anything else needed? Happy to make any additional changes.

EvanYao826 · 2026-06-04T12:14:22Z
