[I] [Bug] plugin.http.include_http_headers does not work with Spring Boot 3.x / Jakarta EE (Spring MVC 6.x plugin) [skywalking]
ardacuhadaroglu opened a new issue, #13938:
URL: https://github.com/apache/skywalking/issues/13938
### Search before asking
- [x] I had searched in the [issues](https://github.com/apache/skywalking/issues?q=is%3Aissue) and found no similar issues.
### Apache SkyWalking Component
Java Agent (apache/skywalking-java)
### What happened
When using plugin.http.include_http_headers configuration with a Spring Boot 3.5.7 application running on embedded Tomcat 10.x (Jakarta EE), the specified HTTP headers are never collected or displayed in the trace span tags.
The tomcat-10x-plugin correctly creates the Entry Span and plugin.tomcat.collect_http_params=true works as expected (query parameters appear in tags). However, plugin.http.include_http_headers has no effect regardless of configuration.
Root Cause Analysis:
The AbstractMethodInterceptor.java in the mvc-annotation-commons module imports javax.servlet.http.HttpServletRequest:
```java
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
```
Since Spring Boot 3.x / Spring MVC 6.x uses the jakarta.servlet namespace exclusively, the header collection logic that depends on javax.servlet.http.HttpServletRequest silently fails at runtime. The mvc-annotation-6.x-plugin loads successfully and instruments controller classes (no WARN logs), but the shared commons interceptor code that handles include_http_headers cannot operate on jakarta.servlet request objects.
Agent configuration used:
```properties
plugin.springmvc.collect_http_params=${SW_PLUGIN_SPRINGMVC_COLLECT_HTTP_PARAMS:true}
plugin.tomcat.collect_http_params=${SW_PLUGIN_TOMCAT_COLLECT_HTTP_PARAMS:true}
plugin.http.include_http_headers=${SW_PLUGIN_HTTP_INCLUDE_HTTP_HEADERS:Authorization,User-Agent,Content-Type,X-Trace-Id}
plugin.http.http_headers_length_threshold=${SW_PLUGIN_HTTP_HTTP_HEADERS_LENGTH_THRESHOLD:2048}
```
### What you expected to happen
When plugin.http.include_http_headers is configured with header names (e.g., Authorization,User-Agent,Content-Type,X-Trace-Id), those headers should appear as tags (e.g., http.headers) in the Entry Span of the trace when using the mvc-annotation-6.x-plugin with a Jakarta EE / Spring Boot 3.x application.
### How to reproduce
1- Create a Spring Boot 3.5.7 application with a simple REST controller:
```java
@RestController
public class TestController {
@GetMapping("/test")
public String test() {
return "ok";
}
}
```
2- Download SkyWalking Java Agent 9.6.0.
3- Copy optional-plugins/apm-springmvc-annotation-6.x-plugin-9.6.0.jar into the plugins/ directory.
4- Configure agent.config:
```properties
plugin.springmvc.collect_http_params=${SW_PLUGIN_SPRINGMVC_COLLECT_HTTP_PARAMS:true}
plugin.http.include_http_headers=${SW_PLUGIN_HTTP_INCLUDE_HTTP_HEADERS:Authorization,User-Agent,Content-Type}
plugin.http.http_headers_length_threshold=${SW_PLUGIN_HTTP_HTTP_HEADERS_LENGTH_THRESHOLD:2048}
```
5- Start the application with the agent:
```bash
java -javaagent:/path/to/skywalking-agent.jar \
-Dskywalking.agent.service_name=test-service \
-jar application.jar
```
6- Send a request with headers:
```bash
curl "http://localhost:8080/test?testParam=hello" \
-H "Authorization: Bearer test-token" \
-H "Content-Type: application/json" \
-H "User-Agent: TestAgent/1.0"
```
7- Open SkyWalking UI → Trace → click the Entry Span → check Tags section.
Actual result: Only http.params tag is present with testParam=hello. No header-related tags appear.
Expected result: An http.headers tag should be present containing the specified header values.
### Anything else
- Agent version: 9.6.0 (build 9.6.0-8c649c4)

Yes, your analysis is correct. All those plugins have to be changed to adopt both, a very bad chaos of JVM.
