Description

camunda-webapp-webjar 7.22.0 causes IllegalArgumentException on org.springframework.web.servlet.resource.ResourceHttpRequestHandler v6.2.0-RC3

Steps to reproduce

create an application with spring boot 6.2.0-RC3 and camunda-webapp-webjar 7.22.0 included by camunda-bpm-spring-boot-starter-root 7.22.0

Observed Behavior

During context loading the ResourceHttpRequestHandler class scans all possible paths and if these do not end with "/" an IllegalArgumentException type exception is thrown with message "Resource location does not end with slash: …" (see ResourceHttpRequestHandler@283 the call to ResourceHandlerUtils::assertLocationPath). The path provided by your library is "classpath:/META-INF/resources/webjars/camunda" which as you can see does not contain the final "/". Could you fix it in a next minor? This is critical as the current version of camunda-webapp-webjar (7.22.0) is unusable with spring-boot 6.2.0-RC3.

Expected behavior (Required on creation)

All path from library should ends with "/"

Root Cause (Required on prioritization)

Path from library not ends with "/"

Solution Ideas

Add "/" on all path

Hi @milazzo-g,
Thanks for reporting this issue. I will look into it and get back to you.

Hi @milazzo-g,
Camunda 7.22.0 supports SpringBoot 3.3 which is uses Spring Framework 6.1.x
https://repo1.maven.org/maven2/org/springframework/boot/spring-boot/3.4.0/spring-boot-3.4.0.pom

Support for Spring Boot 3.4 is planned to be added for the Camunda 7.23. release. You can see this in the Camunda Platform Announcements

Spring Boot 3.4 supports Spring Framework 6.2.x:
https://repo1.maven.org/maven2/org/springframework/boot/spring-boot/3.4.0/spring-boot-3.4.0.pom

I don't get any errors on startup but still getting a warn from ResourceHandlerUtils

2025-02-21T14:14:08.605Z  WARN 28703 --- [cards] [           main] o.s.w.s.resource.ResourceHandlerUtils    : Appended trailing slash to static resource location: classpath:/META-INF/resources/webjars/camunda/

I tried to manually adjust properties by adding to my application.yaml:

webapp:
  webjar-classpath: /META-INF/resources/webjars/camunda/
  security-config-file: securityFilterRules.json

but then I get a 404 when accessing the webapp

java.io.FileNotFoundException: class path resource [META-INF/resources/webjars/camunda//app/cockpit/index.html] cannot be opened because it does not exist

Hi @venetrius, can you check @jpbassinello latest message?

[venetrius]

Hi @jpbassinello,
Do you have the same setup as described in the issue description?
Would you able to check if you have the same issue when building you app with the latest alpha release ? If yes, I would advise you to open a new bug report.

Thanks,
Gergely
