New Spring controller instrumentation modules #1675

jtduffy · 2023-12-22T18:48:50Z

Overview

Resolves #1576
These instrumentation modules support proper transaction naming (route + HTTP method) of traditional annotated spring controllers as well as controllers that inherit annotations from interfaces, super classes or custom annotations. Check one of the README files in the PR for a full description.

spring-4.3.0: This module provides instrumentation for Spring Controllers utilizing Spring Web-MVC v4.3.0 up to but not including v6.0.0. (v6.0.0 instrumentation is provided by another module).
spring-6.0.0: Identical to spring-4.3.0 except for javax -> jakarta namespace.
spring-webflux-controller-mappings-5.0.0: Same functionality as the above modules except for Webflux rather than WebMVC.

Note that because the new instrumentation can change transaction names, enabling this "enhanced transaction naming" is gated by a configuration flag enhanced_spring_transaction_naming, which is false by default:

class_transformer:
    # Enhanced Spring transaction naming.
    # This feature will name any transaction that originates from a Spring controller after
    # the defined route and HTTP method. For example: "/customer/v1/edit (POST)".
    # This includes controllers that implement or extend interfaces/classes with WebMVC related
    # annotations (@RestController, @Controller, @RequestMapping, etc). By default, this is configured
    # to false, which will name transactions for those types of controllers based on the controller
    # class name and method. For example; "CustomerController/edit". This is the naming logic carried
    # over from previous agent versions. "Standard" controllers, with all relevant annotations
    # present on the actual class, will still get named based on route and HTTP method.
    enhanced_spring_transaction_naming: false

Testing

The agent includes a suite of tests which should be used to
verify your changes don't break existing functionality. These tests will run with
Github Actions when a pull request is made. More details on running the tests locally can be found
here,

Checks

Your contributions are backwards compatible with relevant frameworks and APIs.
Your code does not contain any breaking changes. Otherwise please describe.
Your code does not introduce any new dependencies. Otherwise please describe.

Looks like you re added this webclient that I had moved as it was not in alphabetical order.

Was this 6.0.0 supposed to be the module version? This is in the 4.3.0 module.

Same 6.0.0 here.
And , on the line below.

You already have the transaction here. Any reason to get it again from the API?
The log message is ending with , . This gives the impression that there would me more content on this log message. Was there supposed to be?

I'll address this in all 3 modules.

Do we still need the weave-violation-filter?

I was going to create another issue to discuss this later. I don't know if it has any applicability outside of the spring controller stuff or not.

Is this the case of a RouterFunction?

No, this checks the case of a controller method that has no Spring controller annotations at all (like actuator endpoints or error handlers).

meiao · 2024-01-16T15:39:54Z

+            //named them
+            boolean isEnhancedNaming = NewRelic.getAgent().getConfig().getValue("class_transformer.enhanced_spring_transaction_naming", false);


This could be a constant in SpringControllerUtility.

I'll address this in all 3 modules.

Same for weave violation filter.
