feat: add Jakarta EE Servlet 6.0 adapter module (#2998)

[EvanYao826]

Fixes #2998

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.

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

1. 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.

2. 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!

1. CLA: Already signed ✅
2. JDK 8/11 test failure: I have identified the issue — the PR branch has an outdated CI config that doesn't include the -Dskip.spring.v6x.test=true flag for JDK 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.

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

1. 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.

2. 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!
