Nikita updated CAMEL-22849:
---------------------------
Summary: AS2 server/listen does not resolve requestUriPattern wildcards
when selecting consumer configuration (was: AS2 server/listen does not resolve
`requestUriPattern` wildcards when selecting consumer configuration)
> AS2 server/listen does not resolve requestUriPattern wildcards when selecting
> consumer configuration

> Key: CAMEL-22849
> URL: https://issues.apache.org/jira/browse/CAMEL-22849
> Project: Camel
> Issue Type: Bug
> Components: camel-as2
> Affects Versions: 4.14.3
> Environment: *Environment*
> * Camel version: 4.14.x (observed on {*}4.14.3{*})
> * Previous working version: 3.22.x
> * Component: camel-as2
> * Server endpoint: as2:server/listen
> * Configuration example:
> ** requestUriPattern={*}/receiver/*{*}
> Reporter: Nikita
> Priority: Major
> Attachments: AS2.png
>
>
> AS2 server routes configured with *requestUriPattern* wildcards (e.g.
> {*}/receiver/*{*}) no longer resolve the correct *AS2ConsumerConfiguration*
> for incoming requests.
> When an AS2 request is sent to a concrete path like */receiver/test-1,* the
> server logs:
> {code:java}
> No AS2 consumer configuration found for canonical path: /receiver/test-1.
> Encrypted messages will likely fail.{code}
> Debugging shows that *AS2ServerConnection.consumerConfigurations* contains
> the configuration under the key */receiver/*,* but
> *getConfigurationForPath(String path)* performs an exact map lookup using the
> resolved request path ({*}/receiver/test-1{*}), which results in null.
> This behavior breaks encrypted and/or signed AS2 messages, because the server
> cannot locate the appropriate consumer configuration for decryption and
> signature validation.
> This worked correctly in Camel, for example, 3.22.x and appears to be a
> regression in Camel 4.14.3.
> *Environment*
> * Camel version: 4.14.x (observed on {*}4.14.3{*})
> * Previous working version: 3.22.x
> * Component: camel-as2
> * Server endpoint: as2:server/listen
> * Configuration example:
> ** requestUriPattern={*}/receiver/*{*}
> *Steps to Reproduce*
> # Configure an AS2 server route with:
> as2("server/listen?requestUriPattern=/receiver/*&serverPortNumber=8190")
> # Enable encryption and/or signing on the server.
> # Send an AS2 request to: /receiver/test-1
> # Observe that the server logs a warning and does not apply the consumer
> configuration.
> *Expected Result*
> The AS2 server should resolve the consumer configuration when the incoming
> request path matches the configured *requestUriPattern* wildcard.
> *Actual Result*
> The server only attempts an exact match on the canonical request path and
> ignores wildcard patterns, resulting in no configuration being found.
> *Suggested Solution*
> Update *getConfigurationForPath(String path)* to support wildcard (pattern)
> matching instead of exact key lookup only.
> If the incoming request path matches a configured pattern, return the
> corresponding *AS2ConsumerConfiguration* immediately.
> *Conceptual example*
>
> {code:java}
> Optional<AS2ConsumerConfiguration> getConfigurationForPath(String path) {
> AS2ConsumerConfiguration exact = consumerConfigurations.get(path);
> if (exact != null) {
> return Optional.of(exact);
> }
> for (Map.Entry<String, AS2ConsumerConfiguration> entry :
> consumerConfigurations.entrySet()) {
> String pattern = entry.getKey(); // e.g. "/receiver/*"
> if (matches(pattern, path)) {
> return Optional.of(entry.getValue());
> }
> }
> return Optional.empty();
> }
> boolean matches(String pattern, String path) {
> // simple wildcard support, e.g. '*' matches any characters
> }
> {code}
> This would restore compatibility with *requestUriPattern* behavior from Camel
> 3.x and prevent encrypted AS2 messages from failing due to missing
> configuration.
